About Vitrified Grinding Wheel
1.all bench and pedestal wheels must be dressed to prevent loading,loading can cause excessive heat, damage to the workpiece and wheel breakage.dressing exposes new cutting edges and provide chip clearance
2.Do not grind wood,plastic or any other non-metallic material on a bench or pedestal grinder
3. Wheel dressing
Single Point Diamond Tools
- Rigidly mount Single Point tools at a 10°-15° angle to the wheel centerline with a line drawn through the center of the wheel, pointing in the direction of wheel travel.
- Point of contact should be slightly below centerline of wheel.
- Use coolant whenever possible.
- Normal infeed is .001" per pass.
- Lead selections range from .002" - .010" per wheel revolution.
- Rotate the tool 1/4 turn periodically to maintain a sharp point.
Multi-Point Diamond Tools
- Most multi-point tools are used for straight face dressing.
- Tool should have full face contact with the wheel.
- With new tool, 3–5 passes at .005" per pass should be taken to expose diamonds.
- Infeed per pass .001" - .002"
- Use coolant whenever possible.
- Use appropriate lead (and traverse rate).
About Cup Brush
1. Always ensure proper mounting of floorstang and swingframe wheels by mounting with arrow down as marked on wheel.
2. Always use safety guard
3. Always run wheel for 1 minute before grinding
4. For optimum performance, ensure adequate air pressure and air volume when using pneumatic machines
5. Use constant surface foot per minute machines for highest efficiency
6. Do not overdress the wheel face
7. Avoid loading or glazing by changing the contact angle
use pressure assist whenever possible to attain maximum cut rate
8. Maintain recommend air supply (pressure and volume) for highest efficiency
About Flap Disc
1.For comparable finish, use one grit coarser than resin fiber discs. except in 36 grit.
Operator type 29/27C flap disc at a 15°-25° angle; operate type 27(regular and jumbo/high density ) flap discs at an angle less than 15°,more severe angles will weaken flap edges
