Circular grinder 3У12АФ11 (D200х450/500)

Universal cylindrical grinding machine semiautomatic 3У12АФ11 is designed for grinding of external and internal cylindrical, tapered and end surfaces in install the parts in centers, jaw Chuck, face plate or collets in small-scale and series production.

The processing on the machine 3У12АФ11 longitudinal or made flush by grinding in a semiautomatic cycle. The machine has a swivel top Desk and swivel grinding head. It gives the ability to grind not only cylindrical, conical and flat surface.

Using the control arm includes a rapid supply-withdrawal of wheelhead, inset feed, enable, and disable rotation of the product and coolant, turning on the turn table and unloading pump (in between processing details).

On the machine you can perform the following types of processing:

• longitudinal and plunge grinding in manual operation to lock or device of the active control in semi-automatic cycle;
• longitudinal grinding until it stops with automatic intermittent cross feed, accessed by the reverse of the table;
• grinding end surfaces of the periphery of the circle.
