D-Turn HD

Product catalog summary
Overview: The D-Turn HD is a heavy-duty lathe designed for machining large diameter and long workpieces, offering a robust structure and high precision for both rough and finish machining.
Specifications: The lathe features a heavy FC-30 cast machine bed with strong ribbing to minimize vibrations, transmission gears and shafts made of hardened and ground high alloy steel, and a robust multi-plate clutch for driving the main spindle. The machine bed guideways are case-hardened and ground for long-term precision, and the X and Z axes are coated with Turcite B.
Standard Configuration: Includes a 3-axis digital readout, faceplate with 4 jaws (Ø1000 mm), 4-post toolholder, dead center, spindle sleeve MT6, steady rest, tailstock with two spindle sleeve feeds, rapid traverse switchable in X and Z-axis, automatic central lubrication, electromagnetic spindle brake, foundation screws, machine feet, auxiliary service tools, and an operation manual.
Optional Configuration: Offers a double chuck system, additional power spindle motor, various sizes of 3-jaw and 4-jaw chucks, follow or steady rest, taper attachment, quick-change toolholder, hydraulic copying attachment, guideway guard, drilling and milling attachment, and support grinding attachment.
Technical Specifications: The D-Turn HD 480 and 560 models have varying center-to-center distances (2000 mm to 8000 mm), turning capacities (Ø960 mm and Ø1120 mm respectively), and swing over carriage and gap dimensions. The spindle speed range is 4–420 rpm, with a spindle bore diameter of Ø152 mm (options for 230 mm or 305 mm). The main spindle motor is 22 kW, and the machine weight ranges from 8300 kg to 15400 kg depending on the model.
Spindle & Headstock: Features a bore size of 6”, 9”, or 12”, with a turbine speed change mechanism and an adjustable electromagnetic brake. The gear and shaft are made of super alloy material, and the lubrication system is a sealed oil bath with a mechanical pump.
Base: The base is a one-piece casting with reinforced inner structure, suitable for large workpieces and heavy-duty cutting. The gap part base is specially reinforced to maintain cutting stability.
Apron and Accessories: Equipped with rapid feeding, transmission, forward and reverse movement, and a safety device. Accessories include a tailstock with quill diameter options, follow rest, steady rest, boring attachment, back splash guard, quick change tool post, and more.
Digital Readout and Scales: The 3-axis digital readout is suitable for lathes, drilling, milling, and grinding machines, offering high precision and easy installation. It includes features like tool diameter compensation, linear rows of holes, bolt circle processing, and pocket milling function.
Technical Specifications: The digital readout system operates on 80 to 260 V, 50-60 Hz, with a power consumption of 25VA. It includes a range of functions such as angular and bow function, memory positions, and optional RS232 interface.
