Product Usage Instructions

Preparation for Operation
The following procedure is recommended for correct drilling using the Brobo Group Drill:

1. Clean the workpiece to ensure it is free of any grit, swarf, or flammable substances. Use a solvent that is inflammable and non-toxic to remove any residue.
2. Prior to drilling, clear the drill and the work area around the workpiece of any swarf or tools to minimize the likelihood of user injury during the drilling operation.
3. Load the workpiece into the mechanical vice (sold separately) located on the rack lift and fasten it securely. Adjust the height and horizontal position by loosening the rack lift. Once the workpiece is in the desired location, relock the rack lift assembly.
4. Check that the correct drill speed setting is selected and position the safety eye shield to deflect swarf and any dislodged particles.
5. Turn the machine on. Slowly drill into the workpiece until a guide indent is created. Gradually increase the feed rate by applying a constant yet steady force on the feed handle until the desired hole depth is reached.
6. Reverse the direction of the drill feed until it comes to rest in its start position and turn the drill machine off.

Operation Recommendations
To reduce frictional contact between the drill bit and workpiece, apply a light coating of oil or lubricant to the drill bit prior to drilling. Do not force the drill bit through the workpiece as this significantly reduces its lifespan and increases the risk of bending or breaking, which can injure the operator. When drilling larger hole diameters through thick materials, it is advisable to split the drilling operation into two or three stages. Start by drilling a smaller hole size and gradually  increase it until the desired final hole size is achieved.

Warning – Jamming
If the drill jams during a drill, engage the emergency stop immediately. Remove the part and check that the drill bit is not damaged. If necessary, replace the drill bit.

Preparation for Operation

The following procedure is recommended for the correct drilling using the Brobo Group Drill

WARNING – SAFETY GEAR
Protective clothing, safety glasses and gloves should always be worn while loading parts, operating the machine, or undertaking any maintenance work on the machine.

PROCEDURE

1. Clean the workpiece to ensure it is free of any grit, swarf or flammable substances. It is highly recommended that a solvent is used to remove any residue while ensuring the solvent is inflammable and non-toxic.
2. Prior to drilling, clear the drill & the work area around the workpiece of any swarf or/and tools to minimize the likelihood of the user getting injured during the drilling operation.
3.  Load the workpiece into the mechanical vice (sold separately), located on the rack lift, & fastened the workpiece securely. Loosen the rack lift & adjust the height & horizontal position. Once you have positioned the workpiece into the desired location, relock the rack lift assembly.
4. Check that the correct speed drill speed setting is selected, & the safety eye shield is directly positioned to deflect the swarf & any dislodged particles.
5. Turn the machine on. Proceed by slowly drilling into the workpiece until a guide indent is created. Steadily increase the feed rate of drilling by applying a constant yet steady force on the feed handle until the desired hole depth is reached.
6. Reverse the direction of the drill fed until it comes to rest in its start position & turn the drill machine off.

Operation Recommendations

• To reduce the amount of frictional contact between the drill bit & workpiece, a light coating of oil or lubricant can be applied to the drill bit price to drilling.
• Do not force the drill bit through the workpiece as this significantly reduces the lifespan of the bit, as well as increasing the risk of the bit bending and/or breaking & injuring the operator.
• When drilling through larger hole diameters through thick materials, it is advisable to split the drilling operation into two or three stages, starting from drilling a smaller hole size & increasing it until the desired final hole size.

WARNING – JAMMING
If the drill jams during a drill, engage the EMERGENCY STOP immediately. Remove the part, check that the drill bit is not damage and if need be, replace the drill bit.

Advice for the Operator

• Protective eyewear or goggles must be worn at all times while attending & operating the drill.
• Do not attempt to operate the machine unless all safety guards are in operation.
• Ensure that hands & arms are kept clear of the drilling zone when the machine is operating.
• Do not wear loose clothing with long sleeves & oversized gloves, bracelets, necklaces, or any other loose object that may become entangled in the machine’s tooling bit during drilling. Long hair must be tied back or placed in a hair net.
• Always disconnect the power supply to the machine before carrying out any maintenance work or adjustments. This includes cases of abnormal operations of the machine.
• Any maintenance work performed on the hydraulic, pneumatic or coolant systems must be carried out only after the pressure in the system has been released.
• The operator MUST NOT conduct any risky operations or those not required for the drilling in the course (e.g. remove swarf shavings from the machine while drilling).  Never move the drill while the machine is operating.
• Always keep the workplace are as clean as possible.  Remove equipment, tools or any other objects from the drilling zone.
• Support the workpiece to prevent it from falling or jamming during the drilling cycle.
• If the drill bit is jammed during a drill, activate the emergency stop function immediately. Do not continue forcing the drill bit through. This could damage the drill, the specimen or be a cause for potential injury to the operator.
• Always turn off the machine before carrying out any repair work. Consult the Brobo Group Engineering Department in the country in which the machine was initially purchased.

Main Applications and Features

• Applications include drilling, spot facing, chamfering, reaming, tapping and boring.
• The headstock and worktable are easily adjusted, the headstock and worktable can be moved up and down and be rotated 360° around the vertical column.
• The headstock and worktable can also be leaned ±90° and spun 360°.
• Depth of drilling is ensured by a scale fixed on the sleeve and a setting nut.
• Tools/arbors are easily changed using the tool retracting dial.

Transmission System
(As shown in Figure 2)

• The spindle has 6 different speeds which is driven by a motor shaft I through gears 6 & 7 to shaft II, and gear 2 to gears 3, 4 & 5 to shaft III, then gear 1 to gear 8 to spindle.
• Spindle feeding downward is performed by gear 9 driving rack of the spindle sleeve, and repositioning of the spindle sleeve can be performed automatically by spring fix adjustment on gear 9.

Electrical system

Lubrication
Top up lubrication oil No. 30 to the headstock every 6 months, the lubrication oil should be added once a week (ball valves), reference figure 5 for the location of lubrication.

Lifting and Installation

All locking handles must be locked before lifting (Lifting point shown in figure 6).
When installing the machine, bury the foot-screw in a cement foundation according to the position of base holes, after the cement has condensed completely, place the machine on the cement foundation and secure to footing screws.
