This remarkable series of machines is expertly engineered to accommodate hard alloy and ceramic cutting tools, making them ideal for machining both ferrous metals and select non-metallic components. They excel in processing the outer cylinder both inside and out, tackling cone surfaces, grooves, boring tasks, as well as coarse and fine rotary surface turning with unparalleled precision.
The machine's main drive is powered by a robust DC motor, interfaced through a sophisticated dual-spindle speed change mechanism to achieve an expansive workbench speed range. This machine boasts a frame-type construction, linking left and right columns, beams, and a table base with formidable structural rigidity. The beam clamping mechanism features a hydraulic locking device for multiple stations, ensuring stable and reliable operation.
Equipped with an innovative double-frame structure, the machine's feeding head showcases cutting-edge design. The right tool post is a numerical control tool rest while the left accommodates an SPC tool rest. The machine tool rest slide offers horizontal X and U axis movements, along with vertical Z and W axis actions, driven by precision servo motors. This ensures a high degree of accuracy, with gears and ball screw transmissions facilitating both feed and rapid movement.
The workbench is designed with a superior thermal symmetric structure. Its main shaft features high-precision, adjustable double-row short cylindrical roller bearings for radial clearance centering. The axial component utilizes a constant current static pressure guide rail and includes an oil temperature control device. This provides the workbench with exceptional rotational accuracy, significant load-bearing capacity, and minimized thermal deformation.
The vertical tool rest employs a horizontal guide rail with oil static pressure unloading, complemented by a skid composite guide rail and a sliding guide rail for vertical ram motion. This design ensures smooth and efficient operation of the machine's vertical movements.
The machine's numerical control system can be outfitted with either Siemens or Rexroth systems, offering versatility to meet specific customer requirements. Clients also have the option to select alternative systems, tailoring the machine's capabilities to their precise operational needs.
