Linear and Boxway are just perfect match
» X-axis-

With a large span design and high rigidity Linear Roller Guides.
Three linear slide rails with nine linear slides that make axial more high-rigid and increase stability.

» Z-axis-

Equipped –V- Boxway design, ensure the grinding straightness
With incessant lubrication system can lower friction coefficient and become more smooth while axial moving.


High rigidity of cartridge-type A2-6 spindle

Air-flow slide rail

It could be set to any position flexibly depends on the any length of workpiece
Its angles can be set in -5° to +15°

Steady Rest

It could be used with workpiece when needed, and would be more precise while grinding
