SK-51 Type A Questions

Answers to common questions about the SK-51 Type A.

The SK-51 Type A CNC Swiss-type Automatic Lathe is particularly well-suited for industries that demand high-precision machining of complex, small-to-medium-sized parts. These industries include automotive, where tight tolerances are critical for components like fuel injectors and sensor housings, medical, for producing precision surgical instruments and implants, and aerospace, where high-strength, lightweight parts are needed. Additionally, the electronics and micromechanics sectors benefit from the SK-51’s ability to handle intricate components with exceptional accuracy and efficiency.

The main spindle of the SK-51 Type A CNC Lathe has a maximum speed of 5,000 RPM and is powered by a 7.5kW (continuous)/11kW (15 minutes) motor. It also features C-axis control for precise indexing and a through-spindle hole diameter of Ø52.5mm (2-1/16 inches). The sub spindle of the SK-51 Type A has a maximum speed of 5,000 RPM, powered by a 7.5kW (continuous)/11kW (15 minutes) motor. It also features C-axis control and can handle a maximum parts projection length of 80mm (3-5/32 inches)

The SK-51 Type A CNC Lathe features twin 12-station turrets, each capable of holding up to 2 tools per station, 3 counterface sleeves per station, and 2 power-driven tools per station. Contact our specialist for more technical details.

The power-driven tools on the SK-51 Type A can reach spindle speeds of up to 6,000 RPM, driven by a 4.5kW (continuous)/7.5kW (5 minutes) motor. The maximum drilling capability is Ø16mm (5/8 inches), tapping capability is M12 x P1.75, and milling capability is Ø20mm (25/32 inches). Did you download CNC Swiss type automatic lathe brochure?

The rapid feed rates for the SK-51 Type A are 20m/min for X1 and X2 axes, 15m/min for Y1 and Y2 axes, and 40m/min for Z1, Z2, and Z3 axes. The C1 and C2 axes have a rapid feed rate of 550 RPM.
