7 keys to perfect lathe cutting of rubber gaskets
- Rubber compound
- High X linking density
- Good ratio between filler and plastisizer
- High tear resistance
- Blade
- Hard surface, treated or Tungsten Carbide
- Fine grains for perfect surface
- Slim (asymmetric cutting angle)
- Circular for best surface, pin ended for high speed
- Lubricant
- Low friction
- Low viscosity (can be even compressed air)
- Environment friendly
- Machine
- Precise
- Solid, low vibration, heavy
- Compact
- Spindle
- Loose or tight fit
- No longitudinal tension (air support)
- Well centered
- Speed / feed rate
- Rpm*dia must fit to compound and blade
- Feed rate in constant relation to speed
- CNC axis better than curved cam control
- Position (of blades)
- Exact orthogonal to hose axis
- Below centre for pin end blades (depending on direction)
- On centre for circular blades
