Bench Lathe SC4

with automatic crossfeed and longitudinal feed

Bench late with 510 mm distance between centers and 105 mm swing over bed.

NEW brushless motors with 1 KW drive power! resulting in maximum torque and quiet operation in all speed ranges

The combination of brushless DC motor, advanced electronic speed controller and direct belt drive from motor to spindle, provide far better torque over a wider speed range (even at low speeds) thus enabling the elimination of the gearbox and resulting in a quieter machine. In addition, fewer wear parts are engaged, which makes the machine generally low in maintenance.
As a result, a maximum of torque and power is transmitted to the workpiece, especially in the low speed ranges. This considerably facilitates parting and tapping.

The covered lead screw makes it possible to produce threads with gradients of 0.25 to 3.0 mm. The lead screw enables to select an automatic feed in the longitudinal and in the cross direction, whereby an optimum and clean work result can be achieved.

A 100 mm three-jaw chuck is supplied as standard.

The bench lathe SC4 is ideal for the production of workpieces of metal, non-ferrous metals and plastics up to a diameter of approx. 100 mm. Also the processing of higher-strength materials, e.g. stainless steel or steel up to approx. 1000 N / mm2 tensile strength is possible without any problem.
