Gear spline-hobbing semiautomatic machine BC-51P, BCH- 613 NC2

main / production /

The semiautomatic machines are intended for treatment of spline shafts, spur and helical gears with modified teeth flank under conditions of job-lot and serial production. Structural features: The semiautomatic machine is made with the horizontal axis of rotation. The workpiece is fastened in spindle head and tightened up by center of tailstock. Tool is installed in the support spindle. The support is fastened to the column traveling along the saddle flat guides in radical sense of workpiece at a speed of radial feed. Hob axial feed is realized due to saddle traveling along the base flat guides. The semiautomatic machine BC-51P is equipped with relay control system and drives of SIEMENS. The semiautomatic machine is equipped with the SIEMENS programmable controller and drives. The semiautomatic machines have a centralized lubrication system.
