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.
