Manufacturer: Machine Tool Plant n.a. Sverdlov

Condition: excellent; with faceplate and rotary table  

General description: The machine may be used for drilling, boring, countersinking, reaming, facing with the radial tool slide of the detachable faceplate, milling with end mills and threading with boring spindle.

The machine model 2E656R features a cross traversing column, stationary plate, adjustable longitudinally movable table, live spindle 160 mm in diameter, adjustable faceplate with facing slide.

Machining of end surfaces and large boring is possible with adjustable faceplate.

Spindle unit is equipped with precision antifriction bearings. Nitrided spindle has high surface hardness and long-lasting precision.

Spindle head and cross slide of headstock column are fixed automatically with electromechanical clamps after stop.

Feed drive is independent from SCR-DC motors.

Speed range of servo motors I...2500 greatly expands operating capacities of the machine.

Operation is remote from control panel on spindle head and from portable panel.

Productivity of the machine is 1,5-3 times higher than that of universal machines.

Accuracy of machining:

consistency of diameter in cross and logitudinal sections 0,03 mm per length 300 mm
evenness of end surface 0,03 mm per length 500 mm
alignment of central hole axis to machined end surface 0,025 mm per length 300 mm
parallelity of central hole axis 0,03 mm per length 300 mm
surface finish Ra 2,5-1,25 
Application: single-item and serial production.
