Circular grinding machine 3У12ВФ11
Semi-automatic 3У12ВФ11 universal circular grinding machine is designed for grinding external and internal cylindrical, tapered and face surfaces when installing parts in centers, cam chucks, on faceplates or collets in small-scale and batch production.
Part processing on the machine is performed by longitudinal or plunge grinding in a semi-automatic cycle controlled by DRO or an active control device (ПАК), which is supplied by order, as well as with manual control.
ПАК allows grinding of shafts in order to ensure target clearance paired with the mating part.
The machine has a rotary top table and a rotary grinding head. This makes it possible to grind not only cylindrical, but also gently sloping tapered surfaces. Indicator device facilitates accurate reading of the angle of rotation of the table when grinding tapers.
Machine control is 1-handle. Using the control level, quick feed-in and out of grinding headstock, plunge feed, turning-on and off of part rotation and coolant supply, turning-on of table stroke and unloading the pump (in between part processing) are carried out.
