CWZ61200 Heavy-Duty Horizontal Lathe
Product Overview The MFG Machinery CWZ61200 is an ultra-heavy-duty horizontal lathe engineered to conquer the most extreme turning operations in the heavy industry sector. Powered by a massive 80kW DC main motor with stepless speed regulation, it is designed to aggressively cut large outer cylinders, annular grooves, inner bores, and complex cones on massive ferrous and non-ferrous workpieces. What sets the CWZ61200 apart is its advanced Triple Rectangular Guideway (3-Way Bed) architecture, which allows the carriage to bypass the tailstock and steady rest for uninterrupted full-length turning. Featuring a thermal-compensating heavy tailstock and a hydraulically shifted 3-speed gearbox, this machine delivers unshakeable rigidity and unparalleled precision for the aerospace, marine, and energy sectors.

Key Features & Advanced Engineering
- Triple Rectangular Guideway (3-Way Bed): The heavily ribbed, box-type bed features three independent rectangular guideways. The front guideways support the carriage, while the rear guideway independently supports the tailstock and closed steady rest. This staggered "pass-by" design ensures the carriage can traverse the entire bed length without any interference, making it the ultimate solution for machining ultra-long shafts.
- Massive 80kW DC Drive & 3-Speed Gearbox: The headstock is driven by a powerhouse 80kW DC motor paired with a hydraulic 3-speed transmission gearbox (1:200 total ratio), delivering massive torque and stepless speeds from 0.8 to 160 r/min. An integrated 8x feed multiplier mechanism drastically expands the machine's feed range for versatile roughing and finishing.
- High-Precision Spindle & Auto-Lubrication: The spindle is supported by high-precision, double-row cylindrical roller bearings with adjustable radial clearance for absolutely smooth rotation. All transmission gears are independently lubricated by a dedicated gear oil pump, complete with an adjustable oil flow distributor to protect critical components.
- Thermal-Compensating Heavy Tailstock: Engineered for extreme loads. The tailstock incorporates a built-in thrust load indicator (dynamometer) to ensure optimal clamping force. To prevent mechanical damage caused by the thermal expansion of heavy workpieces during aggressive cutting, the tailstock quill is intelligently backed by heavy-duty Belleville springs (disc springs).
- Anti-Friction Carriage with Cable Drag Chain: The carriage guideways are lined with premium PTFE (Turcite-B) soft belts to eliminate stick-slip. The entire carriage feed mechanism is synchronized directly with the main spindle (feed per revolution) for ultimate accuracy, while power cables are neatly managed by an industrial-grade cable drag chain system.
- Heavy-Duty Workholding & Steady Rest: Comes standard with a heavy-duty 4-jaw chuck featuring adjustable jaw blocks and sector gears for high-torque clamping. A robust closed steady rest is included to support extremely long/heavy workpieces, virtually eliminating deflection and gravitational sagging.
