OPTIMUM TU 4210 V MANUAL LATHE

Technical Description

The OPTIMUM TU 4210 V is a heavy-duty manual engine lathe designed for precision metalworking applications. It features a robust cast Meehanite machine bed with induction-hardened, ground, and ribbed prism guides for rigidity and accuracy. The lathe offers a maximum swing of 16.54 inches over the bed and a center distance of 39.37 inches, making it suitable for medium-sized workpieces. The spindle bore diameter measures 2.05 inches, allowing the passage of sizable stock material. Powered by a 7.46 HP motor, this lathe delivers powerful performance, with the main spindle running in an oil bath for smooth and reliable operation. The spindle mount complies with Camlock DIN ISO 702-2 No. 6 standards, and concentricity at the spindle nose is guaranteed to better than 0.015 mm. A Siemens Sinamics frequency inverter provides variable spindle speed control ranging approximately 30 to 3000 rpm, enhancing versatility for different machining tasks. The lathe includes hardened and ground Z-axis guideways, adjustable wedge strips, and handwheels with fine scales for precise manual control in both X and Z axes. It also features a centrally lubricated bed slide, safety handwheels with release functions, and an emergency stop with foot control for operator safety. The tailstock is adjustable for taper turning ±10 mm, with a quill handwheel featuring a fine scale of 0.025 mm. Additional conveniences include a coolant system with a separate tank and LED machine lighting. Overall, the OPTIMUM TU 4210 V combines precision engineering, power, and safety features in a compact footprint of approximately 80" x 36" x 64" and a weight of about 3,418 lbs for robust workshop use.
