特点:


1.Hydrostatic bearing supports GW & RW spindles and Hydrostatic guideway is incorporated into Regulating wheel lower slide in order to get high reliability.

2.Push-button operation for easier size control is standard accessories

3.Hydrostatic bearings offer advantages as follows;

 a)no abrasion

 b)extremely low friction and low temperature rise

 c)high oil film stiffness independent on the number of rotation

 d)precise and constant rotating accuracy

4.Open sided support is applied for GW spindle for convenient changeover operation.

5.Hydrostatic guideway gives precise and accurate compensation for long period.
