Spline-hobbing semiautomatic machine BCH-620 NC2 (CNC25)

main / production /

The semiautomatic machine is intended for cutting of spline shafts and years with hobs by method of form-generating. Has an upright arrangement, digital syn-chronous coupling as well as SIEMENS drives and control units. Structural features: The blank to be clamped into attachment which is mounted to the spindle end face of left spindle stock and clamped up with the center of right stock. The hob to be installed on arbour in support which is joined with the col-umn, travelling along the saddle, perpendicularly to base guides, i. e., in radial sense (the radial feed) Hob axial feed is realized due to saddle travelling along the flat horizontal guides of the base. To raise the hob life due to using of cutting edges all over the length the hob travels along the axis periodically (shifting). Synchronous electronic kinematic couplings instead of mechanical ones. Control from the operational control desk with the visualization of duties and parameters.
