CHAPTER 3 - Main Functions & Operation of the Machine
Figure 4. Pedestal Grinder Main Components
3.1.1. Motor
Available in 3 phases 415 volts, the 2.4KW motor is the heart of the grinder unit that produces 2070 rpm 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

3.1.6. Water Pot
Conveniently located to the machine, water, water-based or oil based lubricants can be placed in the water pot in
which the operator can intermittently dip the workpiece in to cool the grinding surface down. Careful note that tools
or heavy objects should not be rested in or on the water pot for safety concerns that it might be obstructing the user’s
access to the emergency stop button
3.2. Preparation for Operation
The following procedure is recommended for the correct grinding using Brobo Group PEDESTAL GRINDERS
PG350
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
