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

The Johnford ST80(100,130)C Horizontal Machining Center is a high-precision, heavy-duty CNC lathe engineered for demanding turning applications. Featuring a robust one-piece 60-degree slant bed constructed from Meehanite iron, the machine delivers exceptional rigidity, thermal stability, and vibration damping. The main spindle offers a maximum turning diameter of 27.560", a swing of 36.220", and a maximum turning length of 129.920", accommodating large workpieces with ease. The 21.000" chuck and 5.470" maximum bar diameter support versatile workholding options. Powered by a 60 HP spindle motor, it achieves up to 1,500 RPM, ensuring high torque and efficient material removal rates. The machine is equipped with a 12-station turret, supporting up to 12 turning tools and 12 rotary tools, each with a 5 HP, 4,000 RPM live tool capability for milling, drilling, and tapping operations. The C-axis enables precise angular positioning, while the Y-axis option expands multitasking flexibility. The X-axis travel is 15.750" and the Z-axis travel is 79.920", with rapid traverse rates of 394 ipm on all axes for fast cycle times. Square box ways and hand-scraped Turcite B sliding surfaces ensure accuracy and durability under heavy loads. The machine integrates a comprehensive coolant system and programmable hydraulic tailstock, with Fanuc CNC control for reliable operation and advanced programming. This configuration is ideal for high-volume, high-accuracy production environments requiring robust performance and multitasking capabilities.
