  2. Motor NVR Switch
  3. Spindle Direction Switch
  4. Magnet Protection Fuse (2A Fast Blow)
[image 13]

 

5.2.1         Magnet Switch

 

The magnet switch (Image 13 - item 1) is an illuminated rocker switch.

When in the on position the switch will illuminate red.

This switch provides power to the electro magnet base.

 

The magnet switch must be turned on as soon as the machine is in position, before any attempt to use the drill is made.

 

The magnet switch also supplies power for the motor to operate, if it is off the motor will not start.


5.2.2         Motor NVR Switch

The Motor NVR Switch (image 13 – item 2) operates the motor spindle.

 

NVR = No Volt Release – The motor switch has an undervoltage release mechanism to switch off the motor if the supply voltage reduces. The switch must be manually reset when the power is retuned, this is a safety feature.

 

There are two buttons.

 

  1. GREEN marked with the symbol ‘I’ this will START the motor unit.
  2. RED marked with the symbol ‘0’ this will STOP the motor unit.

The GREEN-START button is lower and is shrouded to prevent unintentional operation or start up.

The RED-STOP button is raised and unshrouded so it can be quickly accessed in case of emergency.

 

The motor switch will not switch on if the magnet switch is in the OFF position.

The motor switch will not latch on if the magnet protection fuse has blown.

 

 

5.2.3         Spindle Direction Switch

 

The Spindle Direction Switch allows the direction of the spindle/motor to be reversed.

This is a 3-position rocker switch.

 

  1. Up Direction Forward - Normal cutting direction
  2. Centre            No direction  -  Power to motor is interrupted.
  3. Down           s  Direction Reverse  -  Reverse for operations such as tapping.

This switch SHOULD NOT be operated whilst the spindle is in motion.

 

To change the direction of the spindle during cutting, such as during tapping the following sequence should be followed.

 

  • Spindle is rotating in forward direction.
  • Press STOP ‘O’ on the motor switch.
  • WAIT until motor spindle has STOPPED.
  • Change direction switch to reverse position.
  • Press START ‘I’ on the motor switch.

5.2.4         Magnet Protection Fuse

 

The Magnet Protection Fuse protects the magnet from supply issues when being used on site.

 

If the fuse blows it indicates either a problem with the supply or a problem with the magnet.

If the magnet protection fuse blows machine should be checked by qualified service personnel.

 

5.3       Speed and Torque Control

 

SPEED CONTROL

The VERSADRIVE V85T has both Mechanical and Electronic Speed and Torque control.

 

The mechanical speed selector is 2 position a slider, positioned on the side of the motor gearbox.

The mechanical speed position should be set first, choosing the lowest gear ratio will provide the best torque.

 

ALWAYS check that the mechanical speed selector is fully in position before starting the motor.

 

The electronic speed control is via a rotary thumbwheel on the side of the motor. The electronic speed control should be used as a fine adjustment after the mechanical speed has been set.

 

The speed ranges are shown in the table below.

Gear Selector

Speed Range

[image 14] - Upper inset – Electronic Speed Control             Lower inset - Mechanical Speed Selector


TORQUE / POWER BOOST CONTROL

 

In addition to the Electronic Speed Control, the VERSADRIVE V85T has a Torque / Power Boost Control.

This control is primarily for situations where the Electronic Speed Control is at a low position or slow speed and extra Torque or Power is required. This control can be used to boost the Torque / Power up to 2.4 times from its minimum setting.

At high speed settings the Torque / Power Control should be reverted back to its minimum position.

 

 

 

 

 

 

 


 

5.4       Electro-Magnet

 

 

Make sure the magnetic drilling machine is placed on a smooth, clean, level and solid surface without any objects or debris in between to guarantee maximum adhesion.

 

The workpiece must be at least 10 mm thick for the magnet to sufficient to operate the machine.

 

When cutting thin material, it is possible to enhance magnetic adhesion by temporarily adding a piece of similar material to the workpiece on underside to increase the total thickness. [image 15] .

 

 

[image 15]

 

The electromagnet will work best on surface of at least 10 mm thickness.

 

The electromagnet may not be able to create a good enough magnetic field. Causes may be:

 

  • Surface not flat
  • Workpiece not magnetisable (e.g. Aluminium/Stainless Steel)
  • Workpiece coated or painted
  • Workpiece not thick enough

It is the responsibility of the operator to make sure the workpiece offers the best basis for the magnetic drilling machine to adhere and that the machine is secure before use.

 

  • Place the machine on the workpiece
  • Connect the machine to the power supply
  • Position the machine in the exact desired spot
  • Press the red magnet switch to activate the magnet, the magnet switch will illuminate.
  • To deactivate the magnet, press the red magnet switch again

 

Make sure that the magnet attaches securely to the work piece before starting the motor unit of the magnetic drilling machine. HMT magnets have 2 coils; make sure that both coils are in contact with the workpiece. Do not connect any other machines to the same electrical outlet the machine is plugged into, as this could result in the loss of magnetic force.

 

We need to point out that this is only an indication and not a certainty that the magnet will not release from the material. HMT accepts no liability for insufficient adhesion from any cause.

 

ALWAYS use the safety strap included.

 

Drilling above your head is extremely dangerous and is not recommended. For the use of magnetic drilling machines on pipes, curved or non-magnetic materials, we refer you to our website www.holemaker-technology.com where several pipe clamping & drilling systems can be found.

 

 

5.5       Emergency Stop

 

In case of emergency, to quickly stop the motor spindle rotating, hit the RED STOP button on the motor switch. This switch is both raised and unshrouded to enable it to be accessed quickly in an emergency. See [Image 16] below.

 

By hitting the motor stop this will stop the motor but leave the magnet energized for safety.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

[image 16]

5.6       Tool lubrication

 

 

MACHINE IN UPRIGHT DRILLING POSITION

 

In order to use the lubrication system, the tank must be filled with a cutting fluid or oil

 

  • Make sure the flow regulator is closed.
  • Unscrew the fluid reservoir cap.
  • Fill the fluid reservoir with cutting fluid or oil.
  • Replace and secure the cap.
  • Adjust the fluid flow as required using the flow regulator
  • Add more cutting fluid if the shavings (metal chips) become blue.

 

VERTICAL AND OVERHEAD DRILLING POSITION

 

Apply cutting paste or an appropriate lubrication spray.

 

 

 


WARNING:

Do not use the lubrication system in vertical or overhead drilling applications.

Cutting fluid should not be allowed to enter the motor housing of the machine.

Instead use HMT Cutting Paste / HMT AeroPaste Spray Lubricant.

 

Make sure to use only suitable cutting oil or fluid. HMT offers a wide range of cutting lubricants for all tool and material combinations. Proper cooling will help you create better results faster, whilst extending the lifetime of your tools.

FITTING THE MORSE TAPER ARBOR

 

The standard VERSADRIVE V85T machine is supplied with a standard MT3 to Weldon arbor.

 

To fit a morse taper arbor into the machine:

 

  1. Ensure the machine is unplugged from the supply.
  2. Check the morse taper socket in the machine is clean and free of any debris or swarf.
  3. Check that the arbor or tool to be fitted is clean, undamaged and free from debris or swarf.
  4. Align the tang of the arbor with the slot of the machine socket
  5. Push up the arbor firmly making sure the tang has entered the machine slot.
  6. If necessary, the arbor can be tapped with a soft mallet to ensure it has fully engaged into the taper.

 

REMOVING THE MORSE TAPER ARBOR

 

To remove the morse taper arbor from the machine:

 

  1. Ensure the machine is unplugged from the supply.
  2. Turn the spindle by hand to align the spindle slot with the gearbox housing slot.
  3. Insert the drill drift supplied.
  4. Tap the drift whilst ensuring the arbor does not drop and get damaged or cause injury.
  5. REMOVE the drill drift from the machine.

VERSADRIVE RAPID LOCK ADAPTORS

 

 

The VERSADRIVE V85T is supplied as standard with a VERSADRIVE RAPID LOCK Weldon adaptor.

 

The VERSADRIVE RAPID LOCK Weldon adaptor can also be used to adapt other magnetic drill.

 

This adaptor fits directly into the Weldon arbor of the machine to allow rapid loading of all VERSADRIVE tools/cutters.

 

VERSADRIVE RAPID LOCK offers the following advantages:

 

  • Single handed tool change.
  • RAPID and secure tool changing.
  • Quick Release mechanism.
  • Wide variety of VERSADRIVE cutting tools available, Drill, Tap, Countersink, Ream, etc.
  • No tools required (Chuck wrench, Allen Key, etc.)

 

 

 

6.3       Annular cutters

 

Annular cutters only cut material at the periphery of the hole, rather than converting the entire hole to shavings. As a result, the energy required to make a hole is lower than for a twist drill.

When drilling with an annular cutter, it is not necessary to drill a pilot hole.

 

 


WARNING:

Do not touch the cutter or the parts close to the cutter immediately after use, they may be extremely hot and cause burns to the skin. Ensure nobody is in the work area where the metal core is ejected.


 

DRILLING CONDITIONS

 

The ease with which material can be drilled depends on several factors such as the tensile strength and hardness. Whilst hardness and/or strength is the usual criterion, wide variations in machinability can exist among material showing similar physical properties.

 

The drilling conditions are dependent on requirements for tool life and surface finish. These conditions are further restricted by the rigidity of the tool and the work piece, lubrication and machine power available. The harder the material, the lower the cutting speed.

 

Some materials of low hardness contain abrasive substances leading to rapid cutter wear at

high speeds. Feed rates are governed by rigidity of set-up, volume of material to be removed, surface

finish and available machine power.

 

DRILLING A HOLE

 

Now that you have read the explanatory information and safety recommendations above, you are ready to start drilling. Follow these 13 steps below for best drilling results:

 

 

  1. Install the annular cutter.

 

Place the pilot pin into the cutter, as shown in [Image 17]

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

[image 17]

 

 

 

 

Insert the cutter and pin into the machine arbor, ensure both of the cutter shank flats align with the fixing screws on the machine arbor.

 

Once the cutter is aligned and pressed fully home tighten the two Allen screws with the key supplied.

 

ALWAYS MAKE SURE THE POWER PLUG IS DISCONNECTED!

TAKE CARE WHEN HANDLING SHARP CUTTERS

 

  1. Precisely mark the centre position of the of the hole on the workpiece.

 

  1. Use the pilot pin to position the machine and in the correct position, with the tip of the pilot pin to meet the marked center of the hole.

 

  1. Fix the machine by switching on the magnet and verify that the drill is in the right position and that the machine is fully secure on the work piece.

 

  1. Open the valve/tap of the coolant system (if fitted) to allow the coolant oil to flow.

 

  1. Switch on the motor and allow it to run up to the set speed.

 

  1. Use the feed handle to lower the cutter to the workpiece, begin with relatively light pressure until a groove is formed.

 

  1. Apply a regular pressure while drilling. The drilling performance does not improve by putting more pressure on the tool. Too much pressure will overload and slow the motor and as a result your annular cutter will become worn sooner.

A continuous, non-discoloured iron swarf is a sign of correct drilling speed and a well-cooled, sharp cutter. Let the cutter do the job and give it time to cut the metal!!!

 

  1. Adjust the coolant/lubrication supply as necessary.

 

  1. As the cutter approaches break though, apply less pressure.
    The slug will be ejected out of the cutter by the pilot pin. Take care to ensure the ejected slug is contained and does not present a hazard

 

  1. Once the slug is ejected, with the cutter still rotating, reverse the feed handle back until the output shaft is in its highest position and stop the motor unit.

 

  1. Remove any burrs, metal chips and clean the cutter and surface wearing PPE, safely.

 

  1. To remove the annular cutter, hold the cutter whilst releasing the two fixing screws, and pull down the cutter.

 

After drilling the cutter can be hot, resulting in a tighter fitment inside the output shaft. If this makes the cutter hard to remove, wait a few minutes for the cutter to cool down and try again.

PROTECT YOUR HANDS FROM THE SHARP CUTTER!

Caution: The ejected metal core piece drilled out can be sharp and very hot!!

the optional coolant/quick-release arbor.

 

  1. To fit the cutter, lift the collar arrowed.
  2. Insert the cutter and rotate until the flats of the cutter align with the retainers in the arbor.
  3. Release the collar it should drop to its original position.
  4. Check cutter is secure before use.

6.4       Twist drills

 

This magnetic drilling machine can be used with twist drills of the following types.

 

  • HMT VERSADRIVE shank drills – using the VERSADRIVE Rapid Lock Weldon Adaptor.
  • HMT Weldon shank drills – fitted directly into the Weldon arbor.
  • Morse taper shank drills up to MT3 – 27mm – Weldon arbor removed.
  • Plain shank drills used in 3 jaw drill chuck – MT3 drill chuck replaces Weldon arbor.

The Weldon arbor or taper shank drill can be removed by using the drill drift supplied.

 

6.5       Tapping

 

A range of HMT tapping accessories are available, please see the website or online catalogue for the full list.

 

It is advisable to use the Weldon Shank VERSADRIVE Clutched Chuck for tapping of blind holes.

 

When tapping with a magnetic drill it is best to use either spiral flute or spiral point taps to ensure the flutes stay clear of swarf. Swarf in the flutes creates excess drag and loads the motor.

 

To tap a through hole using a drill/cutter and tap.

 

  • Drill the through hole as normal to the tapping diameter for the thread to be cut.

DO NOT switch off the magnet or move the drill.

 

  • Fit the tap directly into the machine of via a tap holder and apply cutting compound or spray lubrication to both tap and workpiece.

 

  • Set the tapping speed, maximum torque is required for tapping so use the gear change to slow the spindle and maintain the electronic speed control to a high setting where possible.

 

  • Ensure the direction switch is in the forward direction and START the spindle.

 

  • Lower the tap with the feed handle, when it comes into contact with the workpiece it will begin to feed through on its own due to the pitch of the tap.

 

  • When the lead of the tap has cleared the thickness of the plate STOP the spindle.

 

  • Whilst the spindle is STOPPED switch over the direction switch to reverse.

 

  • START the drill in reverse, the tap will begin to feed out of the hole.

TAKE CARE to anticipate the feed handles rotating as the tap reverses out of the hole.

 

  • Once the tap has left the hole the drill unit can be raised and the spindle STOPPED.

 

                                   

7         Maintenance

 

 

Your HMT power tool has been designed to operate over a long period of time with a minimum of maintenance. Continuous satisfactory operation depends upon proper tool care and regular cleaning.

 

 


CAUTION: To reduce the risk of injury, turn unit off and disconnect machine from power source before installing and removing accessories, before adjusting or changing set- ups or when making repairs. Be sure the switch is in the OFF position. An accidental start-up can cause injury.

 

Just as every magnetic drilling machine with moving parts, your HMT magnetic drilling machine also needs regular maintenance service. A few recommendations follow:

 

VISUALLY CHECK THE MACHINE FOR DAMAGE

Machine must be checked before operation for any signs of damage that will affect the operation of the machine. Particularly the mains cable, if the machine appears to be damaged it should not be used failure to do so may cause injury or death.

 

CLEANING

  • Clean all dirt, dust, metal chips and burrs of your magnetic drilling machine
  • Blow dirt and dust out of the main housing with dry air as often as dirt is seen collecting in and around the air vents. Wear approved eye protection and an approved dust mask
  • Never use solvents or other harsh chemicals for cleaning the non-metallic parts of the tool. These chemicals may weaken the materials used in these parts. Use a cloth dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.

 

OPERATION OF THE MACHINE

The machines operation must be checked to ensure that all components are working correctly.  Replace any defective parts immediately. This prevents properly function parts from being damaged.

 

CARBON BRUSHES

Brushes should be checked to make sure there is no abnormal wear present. This should be checked at least once a week if used frequently. If the carbon brush has worn more than 2/3 the original length the brushes should be changed. Failure to do so may cause damage to the machine.

 

CHECK MAGNETIC BASE

Before every operation the magnetic base should be checked to make sure that the base is flat and there is no damage present. An uneven magnet base will cause the magnet not to hold as efficiently and may cause injury to the operator.

When the machine is out of use for a longer period, apply a small amount of machine oil to the underside of the magnetic base for rust protection. Clean the magnetic base again with next use.

 


 

CHECK GEARBOX GREASE

The gearbox grease should be checked and replaced at least once a year to ensure maximum lubrication and cooling, and thus the best performance and durability of the machine.

 

CHECK ARMATURE

This should be checked at least once per month to check that there are no visual signs of damage to the body or to the commutator. Some signs of wear will be seen on the commutator over a period of time, as this part comes in contact with the carbon brushes, but any signs of abnormal damage and the part should be replaced.

 

ADJUSTMENT OF SLIDE

An essential requirement of the machine is that the slide can move in a smooth and controlled manner, free of lateral movement and vibration.

 

When supplied new, the output shaft has already been adjusted for ideal movement.
After time and use, the up and down movement may become a little loose, requiring adjustment.

 

Adjustment can be made via the 5x adjustment screws down the side of the main housing.

[image 20]    Slide Adjustment   -   Adjust screws x5

 

 

To adjust the slide

 

  • Lower the slide to its lowest point
  • Adjust each of the 5x screws, in turn as below.
  • Refer to [image 20] . Release the locknut with an 8mm spanner.
  • Adjust (tighten) the socket set screw with a 2.5mm Allen key.
  • Check the slide movement and keep readjusting until there is a slight resistance.
  • When happy with the adjustment lock the socket set screw by tightening he locknut with the 8mm spanner.
  • Check the slide movement.

After adjustment the slide should be easy to move up and down, it should also stay at any height position. Do not overtighten the adjustment screws!

 

 

REPAIR, MODIFICATION AND INSPECTION

Repair, modification and inspection of HMT Magnetic drilling machines must be done by HMT or HMT authorized dealer. The spare parts list will be helpful if presented with the machine to the HMT dealer for service when requesting repair or other maintenance.
