Stone Lapping Unit for flat and spherical surface
SH-20RH-SR
Main Features
- Stone lapping unit for flat and spherical end surfaces
- Installs easily on NC lathes and other general-purpose machines, capable of high accuracy with stability
- When added to a lathe, turning (your process) and stone lapping (this unit) can be performed with one chuck, without needing to re-chuck the workpiece after turning in order to perform stone lapping, which can both improve accuracy and greatly reduce cost
- Speed-controlled stone head allows for flexible setting of rapid forward and backward movement, air cutting, speeds and positions for rough and finish machining, etc.
Unique air bearing mechanism is employed at the grindstone pressure slide guides. Enables ultra-low pressure cutting with zero resistance due to slide friction. - Automated design for rough and finish machining to meet demands for higher accuracy. Selectable optimum machining conditions for both rough and finish machining. Grindstone pressurization is controlled by an electropneumatic regulator, which allows the conditions for multi-step rough and finish machining to be set, further improving accuracy and efficiency. One-cycle automatic machining can be easily operated by a start button or an electrical signal, and a fully automatic machining cycle is also possible by attaching loading and unloading devices.
- Accurate spherical profiles can be obtained by adjusting a swivel mechanism unit (special accessory) of the stone head section to swivel only at the calculated values
