Blackalloy™ "525"™ Spitfire Tools
Blackalloy™
tool compound "525"™ requires a grinding technique
that is not difficult. Several easy precautions are necessary
to prevent cracking and checking.
- Select
the proper grinding wheel. The chart below shows our recommendations
for grinding wheel selection.
- Operate
the wheel in the recommended speed range. Use our simple
cross reference chart to translate your wheel/motor RPM
combination to surface speed.
- Avoid
local overheating by traversing the work continually with
respect to the wheel.
- Use
either a generous coolant supply or none at all. Cutoff
wheels must be run dry.
- Dress
the wheel frequently to keep it free cutting.
- Don't
quench the tool after grinding.
- Don't
use excessively hard wheels. Common aluminum oxide wheels
are more than suitable.
- Don't
use too heavy pressure.
