GA27 Series CNC Cylindrical Grinding Machine (Angular Type)
CNC Cylindrical Grinding Machine (Angular Type)
- Hydropdynamic spindle
- Rotary center/Fixed center head stock
- Manua/ Hydraulic tailstock
- CNC control system
- Grinding cycle
- Wheel dressing cycle
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)
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.
The oil-filled type Iubrication system of tailstock consolidates, and ensures the high-precision of tailstock.
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.
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.
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.
