JOHNFORD - ROUNDTOP MACHINERY COMPANY TC-20 HORIZONTAL MACHINING CENTER

The JOHNFORD-ROUNDTOP MACHINERY COMPANY TC-20 is a precision horizontal CNC turning center engineered for small to medium-sized production and job shop applications. This machine features a robust design with a maximum turning diameter of 11.810 inches and turning length capacity of 20.470 inches, accommodating workpieces up to 2.000 inches in bar diameter. The 8-inch hydraulic chuck provides secure workholding for reliable precision work. The main spindle operates at speeds up to 4,500 RPM with 15 HP motor power, delivering consistent performance across diverse turning operations. A 12-station automatic turret system enables rapid tool changes with 0.2-second indexing time, minimizing non-cutting time. The machine incorporates a secondary rotary tool operating at 6,000 RPM with 3 HP capacity for enhanced machining versatility. The two-axis control system (X and Z axes) provides 6.700 inches of X-axis travel and 15.750 inches of Z-axis travel, both delivering rapid traverse speeds of 590 IPM. The Fanuc 21-T CNC control system offers intuitive programming and reliable operation. Weighing approximately 3,000-3,200 kg with compact dimensions around 1,900mm × 1,400mm × 1,850mm, this machine is ideal for shops with space constraints while maintaining the capability for high-precision turning applications including threading, grooving, and complex profiles.
