Valve spool – centerless grinding
tight tolerances even with the critical shapes of a valve spool
- Grinding of parts with very tight tolerances even with critical shapes (interrupted diameters, parts with holes, cuts, etc.).
- Machine ready to work in infeed and/or throughfeed depending the required production or part batches.
- Non-contact measuring system, for flexibility and quick set-up.
Machining operations
- OD grinding, in infeed or throughfeed, depending on the customer production requirements or part shape if different diameters must be ground.
Tolerances
- Cylindricity: < 0.00006 inch.
- Diametrical tolerance: 0.00008-0.0001 inch.
- Surface finish: Ra 8.
ESTARTA - Centerless grinding machine
- Optimum thermal and dynamic stability: built on a natural granite base.
- An extremely rigid machine, with both grinding and regulating wheel spindles twin-grip supported.
- Machine with glass scales for high accuracy movements (this makes for excellent repeatability of the machine).
- Machine ready to adapt automatic loading solutions for infeed or throughfeed grinding.
