CHAPTER 1 - Installation of the Machine
1.1. Unpacking & Handling the Machine
Upon receiving the Brobo Group BENCH/BUFF GRINDERS 200HD & 250HD, the machine should be standing
upright & positioned centrally on top of a wooden pallet.
Carefully remove the packaging surrounding the grinder unit & elevating the machine away from the box, mindful
that the machine should be equally supported. Position the grinder to the desired location, ensuring that a power
outlet is available & within reach of the grinder power cord.
Prior to powering up the grinder, place the desired wheel/buff mop onto the machine spindles. Note that if the bore
sizes on the grinding wheels &/or buffering mops do not fit the spindle, taper adapters & buff adapters are readily
available for purchase from most hardware & tool outlets.
Once the wheels/buffs are securely fastened to the machine, connect the grinder to the mains electrical supply &
power up the machine.

part of the machine.
This machine involves a high-speed revolution; therefore extreme caution is required when operating the
device.
The employer is responsible for instructing the personnel who, in turn, are obliged to inform the operator of any
accident risks, safety devices, noise emission & accident prevention regulations provided for by national &
international laws governing the use of the machine. The operator must be fully aware of the position &
functions of all the machine’s controls.
All those concerned must strictly adhere to ALL instructions, warnings, & accident prevention standards in
this manual.

 Operator - the person or persons are given the responsibility of installing, operating, adjusting,
maintaining, cleaning, repairing, & transporting the machine.
2.1.1. Noise Level
The noise level of an idling grinder has been measured to be below 85 dBA. This complies with the Australian
Occupational Health & Safety (Noise) Regulations 1992.
Please note that peak impulse noise levels will be experienced due to variables including blade characteristics, type,
& condition. This will also vary accordingly depending on the size & type of sample being ground. Under these
circumstances, management should make available to the operator(s) the appropriate hearing protection equipment
as prescribed under the above-stated act.
WARNING – UNAUTHORISED MODIFICATIONS/REPLACEMENTS/USE

CHAPTER 3 - Main Functions & Operation of the Machine
Figure 4. Grinder Main Components
3.1.1. Motor
Available in single phase 240 volts or 3 phases 415 volts, the 1.1KW CMG motor is the heart of the grinder unit that
produces 2800rpms toward the spindles & is operating at suitable speeds for grinding & buffing applications.
3.1.2. Safety Eye Shields
The reinforced glass safety eye shield serves to protect the user from any debris & particles that might be dislodged
from the grinding/buffing process. The bracket mountings also allow the user to adjust the position of the eye shield
to suit various workpiece.
3.1.3. Grinding Wheel
Rated at A24/46 Grit, the general purpose grinding wheels are provided on all Brobo bench grinding machines. It
is advisable for all operators that grinding/buffing wheels are available for purchase for various applications from
reputable hardware stores. Also note that tapered buff & wire adaptors are available for purchase from Brobo, sold
separately.
3.1.4. Toolrest
As implied, the Toolrest provides a stable platform in which the user can rest any tool piece for resharpening. The
height & position of the Toolrest can be moved accordingly via the adjustable bolts provided.
3.1.5. Emergency Stop Button
In compliance with Australian Standards & ISO 9001, all Brobo grinding/buffing machines are now provided with
emergency STOP button for ease of access during an emergency.

3.2. Preparation for Operation
The following procedure is recommended for the correct grinding using Brobo Group BENCH/BUFF GRINDERS
200HD & 250HD
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 & non-toxic.
2) Prior to grinding/buffing, clear the work area around the workpiece of any sizeable items & tools to minimize
the likelihood of the user getting injured during the grinding operation.
3) Using the Toolrest as a guide, rest the workpiece on the Toolrest & maneuver it to the desired grinding
position.
4) Check that the safety eye shield is directly positioned to deflect swarf & any dislodged particles.
5) Turn the machine on. Proceed by slowly easing the workpiece into the grinding wheel. Apply a steady,
even pressure & feed downward towards the wheel. During grinding, use a traversing motion across the
face of the grinding wheel up to within the edge of the wheel. Take care not to round off the grinding wheel
edges. Do not grind in the one spot on the wheel as this will damage the wheel. Good grinding practice
preserves the shape of the grinding wheel face & reduces the inconvenience & frequency of dressing the
grinding wheel.
6) Once completed, turn the machine off by depressing the stop button.
3.3. Operation Recommendations
 To reduce the amount of frictional heat generated between the grinding wheel & workpiece, a light coating
of oil or lubricant can be applied to the workpiece periodically.
 Do not force the workpiece to the grinding/buffing as this not only significantly reduces the lifespan of the
wheel, the workpiece could recoil sharply backward & injure the operator.
 Adjusting Toolrest: 3mm clearance between Toolrest & wheel face, Align Toolrest above the spindle
Centreline
