Recommendations for the use
of Superabrasives on Handheld
Machines
• Superabrasives are generally inflexible and could shatter, so must
be handled with the utmost care. Damaged or improperly mounted
superabrasives are dangerous and can cause SEVERE injury to the user
and other people in the vicinity
• Types of superabrasive wheels include diamond cutting discs, welded
metal discs, CBN discs etc. Choose your superabrasive tool carefully,
taking into consideration the workpiece material, the machine
dimensions and capabilities. Make sure the machine does not exceed the
maximum operating speed of the superabrasive disc
• NEVER use superabrasive cutting discs for side grinding, as this might
lead to the disc shattering
• Superabrasive wheels have to be carefully inspected and tested before
mounting. Metal wheels should be subjected to a sound test: hold the
wheel on a mandrel or with a finger inserted through the bore, then tap
it with a non-metallic object at several points and listen each time to the
sound produced. An intact wheel will produce a clear ‘bell like’ metallic
sound. Damaged wheels will give a dull, chattering sound. If in doubt, DO
NOT USE, MARK AS DAMAGED AND DISCARD
• Make sure the machine’s mounting flange is compatible with the
superabrasive wheel. Refer to the manufacturer’s mounting instructions
• ALWAYS conduct a test run after mounting, with no load for at least 30
seconds, to determine if the wheel runs balanced and does not produce
excessive vibration. If it does, switch off IMMEDIATELY, remove the disc,
inspect, re-mount and re-test if no damage is detected
• If planning on using the superabrasive wheel with a coolant, liquid dust
suppressant or lubricant, first check if the wheel, machine and workpiece
are compatible with wet cutting and with the compound to be used.
Always apply liquid to an already running wheel, never to a non-moving
tool, as the unbalance could lead to the rupture of the wheel. When
switching off, remove the liquid supply first and let the machine run at
no-load, until centrifugal forces have drained all liquid from the wheel.
Dry off the wheel after use, and prevent liquid from being absorbed into
the wheel
