HMT STC-25/30 HORIZONTAL MACHINING CENTER

Technical Description

The HMT STC-25/30 is a CNC horizontal turning machine designed for bar and chuck operations. Featuring a single main spindle with a maximum turning diameter of 11.810 inches and turning length of 59.060 inches, this machine accommodates a 10-inch chuck diameter and handles bar stock up to 1.750 inches. The spindle delivers dual operational modes: 4,000 RPM at 20 HP for standard turning, or an optional 35,000 RPM at 25 HP for high-speed finishing. With a maximum swing of 16.930 inches, the machine provides ample clearance for workpiece manipulation. The turret-based tool carrier holds up to 12 turning tools, though only one cutting tool operates simultaneously, ensuring precision in each operation. Motion is controlled across two axes: the X-axis provides 12 inches of travel with rapid traverse capabilities up to 394 ipm, while the Z-axis delivers 40.750 inches of travel at matching rapid speeds. This 2-axis configuration enables efficient longitudinal and cross-feed movements for comprehensive turning operations. The machine excels in producing precision components from bar stock or preset chucked workpieces, making it suitable for automotive, bearing, and general engineering applications requiring consistent quality and moderate production volumes.
