High Precision,Sturdy & Durable,Waterproof & Dust-proof,Easy Operation
Hydropdynamic spindle
The grinding wheel spindle is made of high-grade alloy steel (SNCM220) by precision machining, including multiple heat treatment, grinding, polishing, ect. for its durability. The spindle is supported by unique hydrodynamic bearing to reach excellent rigidity and shock resistance.(End measuring device is optional)
Rotary center/Fixec center head stock
The simple and stable head stock is equipped with high-precision bearing, which greatly improves the rigidity and rotation precision of the spindle. Excellent waterproof ability enhances the durability of the machine.
Manua/Hydraulic tailstock
The oil-filled type Iubrication system of tailstock consolidates, and ensures the high-precision of tailstock.
CNC control system
It is equipped with advanced CNC controller and form-filling type operation interface, and has editable standard grinding cycle program. It can also customize the dressing shape for special grinding request. It is easy to learn and understand.

Overview of grinding wheel profile
Grinding cycle
Notes: 1.By separate setting for grinding cycle, the grinding cycle can be divided into rough grinding, medium grinding fine grinding and spark-out grinding.
2.With an automatic measuring device for outer diameter(optional), the grinding volume can be set for plunge or angular grinding.
Grinding wheel dressing cycle
Notes: 1.Diamond dressers can be set up to 5.
2.There are five profile selections for grindind wheel dressing. Both sides can be dressed.
3.Support customized profile setting function with graphical display, up to 40 points.
