STAR SC-20 HORIZONTAL MACHINING CENTER

Technical Description

The STAR SC-20 is a CNC horizontal machining center designed for precision small-parts manufacturing with a maximum spindle turning diameter of 0.780 inches and bar diameter capacity of 0.780 inches. This Swiss-type automatic lathe features a robust dual-spindle configuration with one main spindle and one sub-spindle, enabling simultaneous multi-axis machining operations. The main spindle delivers 4.90 horsepower at 10,000 RPM, while the sub-spindle operates at 8,000 RPM with 1.33 horsepower for secondary operations such as back-working and finishing. The machine accommodates up to six turning tools on the primary slide front tool carrier and four additional turning tools on the secondary slide carrier, with a maximum of three rotary tools rated at 0.50 horsepower and 5,000 RPM. With its six-axis CNC control and two simultaneous cutting tool capability, the SC-20 achieves high productivity through coordinated multi-task machining. The sub-spindle features a 2.170-inch maximum turning length, expanding versatility for complex component geometries. This machine is ideal for medical devices, miniature bearings, fasteners, and other precision components requiring tight tolerances and high throughput in compact production runs, combining Swiss-type lathe efficiency with advanced CNC automation.
