MK7712×250 Spring Grinding Machine

Vertical Double Disc Grinding Machine MK7712×250

Principles

MK77 Series CNC spring double disc grinding machine is suitable to carry out dry grinding. Processing of two-end surface of compressible springs. In two ways, one is gradual grinding, other one is press-in grinding. Control system use PLC and touch screen, so to operation and maintenance is very simple. System can be stored in 20 groups grinding parameters, and can work manually and automatically. In the grinding process, all states and parameters can be displayed on the screen real time and can directly modify the relevant parameters.

Two grinding wheels are installed vertically, their axial lines are in same vertical line. Grinding heads motor with integrated linear guideway structure (patent pending), directly drive grinding wheel with high rotating accuracy, upper and lower grinding heads run through the straight linear guideway, and can be drove by ballscrew, with high precision movement, less driving power and long service life. The slide plate of upper grinding wheel hoists by geared motor to achieve compensation.

Feeding plate is installed at the convertible platform, simple structure and can be suitable for different specification springs. Grinding by replacing the bushing or feeding plate.

Equipment Feature

▼The axial movement of grinding wheel linear guideway, running smooth, high precision and long life;

▼The axial driving of grinding wheels using ballscrew, high precision, long life and small drive power;

▼Grinding wheel dressing tool is drove by motor, high dressing efficiency and smoothness is much better than manual;

▼A aluminum geared motor, high thermal diffusivity, easy maintenance and beautiful appearance;

▼Grinding wheel can install water cooling system optionally, to improve spring grinding yield and product quality;

▼The upper grinding wheel feeding drive can use servo motor, fast feeding response and long life.
