CNC Lathe Machine Model SA1800C130F3 for Efficient Long Part Processing

The lathe with feed-through slides provides optimum technology for machining long workpieces. Due to the fact that the slides are able to bypass the lunettes, go behind the spindle headstock and tailstock, the workpiece is processed along its entire length without re-installation. The machine bed is made of solid cast iron sections, with 4 or 5 guideways: 2 or 3 rolling guides for slides, 2 sliding guides for tailstock and lunettes.

The sections are fastened together with high-strength bolts and pins. Spindle headstock with "C" axis. Range switching is automatic.

Speed control within each range is stepless. Caliper. Two slides move along the Z-axis on rolling guides.

The slides are fitted with sliders that move in the X axis. The right-hand caliper has an integral Y-axis on rolling guides. The Z axis drive is mounted inside each caliper.

The slides are moved by two servo-controlled gearboxes along a rail fixed to the bed. The pinion of one of the gears is the driving gear, and the pinion of the second gear is used for clearance selection. Rear headstock has a built-in quill rotating spindle and hydraulic drive quill with a mechanism to control the clamping force.

Moves on the bed from a separate electric drive.
