Currently JSC ‘Tomsk Vakhrushev electromechanical plant’ produces two types of hand-operated chippers, they are MR-22 and MR-36. These chippers are generally applied in metallurgy and have been estimated at their true worth by many specialists. However the field of chippers’ application is getting larger.
MR-22 chippers are used for fettling of medium-size castings, conditioning of seams and defects of rolled stock. MR-36 chippers are used for fettling of large-size castings, chipping out defects on feed and rolled stock.
The MR-22 and MR-36 chippers differ in length of barrel, striker, housing and sheathing. Chippers are delivered with hexagon chipping bush for setting the chisel.
Chipper represents an air percussive pneumatic machine with drill valve chest working under the action of compressed air.
Chipper is comprised of an air distribution percussion mechanism, a handle unit with a built-in starting device.
Advantages:
- Starting device mantled on the air distributing and air percussion pneumatic mechanisms and linked to the chipper’s body comprise a vibroprotective spring system.
- Compared with the analogs, decreased weight of the hammer lightens its operation.
