•This series of machines adopts an integral box-shaped base, and the rib layout is designed through finite element optimization to make the machine tool more rigid. It uses high-density cast iron with high strength and high vibration absorption;
•The spindle bearing adopts imported high-precision double-row short cylindrical roller bearings and two-way angular contact ball bearings to meet the load-bearing requirements of axial and radial cutting forces;
•The X/Z axis screws are all pre-stretched structures, which can reduce the impact of temperature rise on the accuracy of the screw during machine tool operation;
•The vertical structure avoids roundness errors caused by the gravity of the workpiece during sub-horizontal clamping, ensuring the roundness accuracy of the parts;
•The self-weight of the workpiece ensures a close fit between the workpiece and the fixture, allowing the workpiece to achieve higher positioning accuracy and processing accuracy;
•A variety of chucks are optional, and non-standard fixtures can also be customized according to customer needs;

•Suitable for high-speed steel and carbide cutting tools for rough and finish machining of ferrous metals, non-ferrous metals and some non-metal parts. It can process internal and external cylindrical surfaces, internal and external conical surfaces, arcs, metric and inch threads and various complex shapes. High-speed turning of rotary surfaces.
•All structural parts have been analyzed by finite element and the structure is optimized to ensure the stability of the accuracy of the machine tool in the cutting state. The mechanical rigidity is increased by 30% compared with the traditional design;
•The RT60/80 series uses heavy-duty linear guides, the RT80 series uses sliding guides, and both use C3-level precision ball screws;
•RT60/80 series are equipped with high-performance two-speed motors or two-speed gearboxes, and are capable of low-speed heavy cutting and high-speed finishing;
•The highly rigid spindle unit and the compact design of the built-in oil cylinder in the pulley effectively reduce the height of the entire machine.
