Product Description
High Speed CNC Cylindrical Grinding Machine 
BGK-320    BGDK-320
 

Machine Summary
 As middle and high grade CNC machine tools, BGK-320 and BGDK-320 CNC (end face) cylindrical  grinding machines are independently developed on the basis of applying new technologies and rich  experience of designing and manufacturing CNC grinding machines. Characterized by the  universalization, high-degree modularization, high rigidity, high efficiency, high adaptability, high  precision, easy to operate and reliable performance, these machines are suitable for the mass  productive processing of automobile engine crankshaft, camshaft, differential housing, flange plate, and  parts of transmission system, such as transmission shaft, half shaft, gear (wheel) shaft, etc, in addition,  they also can be applied in the small-scale high precision productions in workshops of military  industries, aviation industry, aerospace industry and common precision machining.

 
Features and Performance
*With the rational layout and integral protective cover, the machine tool is convenient for maintenance and  in conformity with human engineering requirements.
*With a sleeve type hydrostatic/hydrodynamic mainshafting adopted for the grinding wheel spindle, the  machine tool features on the high rotary precision and good rigidity. The linear speed of the grinding  wheel can reach 60m/s (for specially ordered) and that of CBN grinding wheel is 80m/s(for specially  ordered).
*With two-axis linkage feeding, the machine tool is equipped with worktable(Z axis) and a wheel head(X  axis) driven by AC servomotor and ball screws, the maximum feed speed of 10m/min; the feed of the  wheel head is equipped with special vibration absorbing measures.
*The machine tool can be provided with various types of diamond dressers (installed on the rear side of  the work head) according to the needs of customers, thus realizing precise CNC dressing, adapting to  grinding of external cylindrical surfaces, taper surfaces, end faces, shaped cylindrical surfaces arc  surfaces and grooves, ensuring the stability of the fitted precision not less than 80% in case of grinding  batches of tapered surfaces and achieving automatic compensation.
*The machine tool is provided with an imported or a domestic active measuring device, thus realizing the  closed-loop control of grinding process.
*The machine tool adopts an imported advanced CNC system and is provided with all-around controlling  functions including grinding program changes, workpiece quality control, machine condition monitoring,  fault self-diagnostics, abnormal alarm, and convenient menu type interface input.
