Product Description

Machine application:
The machine is used for mass-producing cylindrical parts, ring parts in the way of centerless through feeding. And it also can be used for grinding cone parts with taper less than 1∶20 and molding rotational parts in the way of centerless in-feeding. The machine can carry out auto plunge-in feeding cycle if it is equipped loading & unloading mechanism (optional). It grinds circulation automatically. Suite for volume production.

Machine configuration & characteristics:
1. Gri. wheelhead and reg. wheelhead both can move (gri. wheelhead feeds, reg. wheelhead adjusts). It's convenient to equip  auto-line and loading mechanism(optional) for long job or bearing ring
2. Wide wheel has higher load capacity for reducing the number of time of grinding and enhance productivity.
3. GW. spindle and RW. spindles are both the dual-supporting structure. GW. adopts  multi-dynamic pressure bearings which are lubricated by compelling lubrication oil. RW. Adopts rolling bearing.
4. The gri. wheelhead feeding guideway adopts flat-v antifriction plastic surface guideway. Good anti-vibration and sensitive micro-feeding.
5. RW. Spindle adopts inverter duty AC. motor regulates reg. wheel speed steplessly.
6. The machine is controlled by PLC. Touch screen HMI. Servo motor drives the gri. wheelhead motions of feeding, compensation and rapidly moving.
7. The stepping motor drives the GW. dresser feeding.  It can achieve mutual compensation with the gri. wheelhead. RW. Dresser feeds manually. The reciprocation of GW dresser and RW dresser is driven by hyd. Linear oil cylinder. The speed can be stepless regulated.
