Scenarios of Pneumatic Grinders
Primary applications:
- Welding shops: Removing spatter and smoothing seams
- Auto body repair: Surface preparation before painting
- Foundries: Cleaning castings and removing gates
How to Choose Pneumatic Grinders
Selection criteria:
- Match power (HP) to your air compressor capacity
- Choose disc size based on work area
- Consider weight for prolonged use
- Verify collet compatibility with existing accessories
For occasional use, 0.5HP models suffice, while continuous operations need 1HP+ units.
Pneumatic Grinders Q & A
Q: How long do pneumatic grinders last?
A: With proper maintenance (daily oiling), quality models last 3-5 years of industrial use.
Q: What air pressure is required?
A: Most operate at 90 PSI, consuming 4-10 CFM depending on size.
Q: Are Chinese pneumatic grinders reliable?
A: Yes, when sourced from certified factories. Many global brands manufacture in China.
Q: How to reduce vibration?
A: Look for models with counterbalanced motors and rubberized grips.
Q: Can they be used for woodworking?
A: Not recommended - the high RPM can burn wood. Use electric sanders instead.
