YCM has expanded its TC series of high-performance, high-precision CNC lathes. The user-friendly TC-16 is said to feature a high cost-performance index and is designed for sectors including automotive, electronics and general job shops.
Features include a large through-hole spindle design with 6" and 8" chucks and a maximum turning diameter of 10.24". Large-diameter, double-row, cylindrical bearings enable the rigid spindle to carry a stable axial and radial load, the company says. Spindle power ranges to 20 hp.
According to the company, the efficient and durable linear-guideway design reduces non-cutting time and increases productivity. Direct-drive motors on the X and Z axes restrain backlash and achieve high positioning accuracy, the company says. The X and Z axes offer rapid feed rates of 945 and 1,181 ipm, respectively.
Driven by a servo motor and hydraulic clamp, the turret is designed for fast indexing and versatility with a 10T or 12T capacity.
The 45-degree slant-bed design is said to provide smooth chip disposal and easy operator access. According to the company, a telescopic cover and coolant shower system ease chip removal. The independent coolant tank isolates the base from heat exposure, and the design of main/sub coolant tank is said to simplify cleaning the chip conveyor. The filter and sup coolant tank can be drawn out separately for easy maintenance.
Robotic Cell Cuts Cycle Time, Improves Part Quality
Sew-Eurodrive Inc. worked with Okuma America’s authorized systems dealer, Gosiger Automation, to design an automated cell that includes an automatic, magazine bar feeder that loads 6-ft. lengths of barstock into the machine. The shop also switched to an Okuma twin spindle, twin turret turning center so all of the machining operations are completed in one setup, thus eliminating additional fixtures and operator intervention. The resultant system reduces cycle times and requires much less operator involvement. As a result, production time per part was more than cut in half – from about 5 minutes to 2 minutes, 20 seconds.
