JOHNFORD - ROUNDTOP MACHINERY COMPANY ST80(100, 130)B HORIZONTAL MACHINING CENTER

The Johnford ST80(100, 130)B Horizontal Machining Center is a robust, high-precision turning solution designed for demanding production environments. Featuring a single main spindle with a maximum turning diameter of 27.56" and a maximum turning length of 129.92", this machine delivers exceptional versatility for a wide range of workpiece sizes. The main spindle chuck diameter is 15", supporting a maximum bar diameter of 4.57", and achieves a maximum swing of 36.22". The spindle is rated at 50 HP with a speed of 1,700 RPM, ensuring high torque and efficient material removal. The machine is equipped with a 12-station turret for both turning and rotary tools, with up to 12 rotary tools available, each capable of 5 HP and 4,000 RPM for live tooling operations. The system supports two axes of motion, with X-axis travel of 15.75" and Z-axis travel options of 79.92" or 120.08". All axes offer rapid traverse rates of 394 inches per minute, enabling fast positioning and reduced cycle times. The design incorporates a rigid slant-bed construction for enhanced stability and accuracy, while the separate coolant tank minimizes thermal distortion. Standard features include a programmable hydraulic tailstock, comprehensive coolant system, and hand-scraped sliding surfaces coated with Turcite B for smooth operation and long-term reliability. This machining center is ideal for high-volume, precision turning applications requiring both speed and repeatability.
