1. Main base parts such as pedestal, column, cross beam, sliding seat and spindle box are made of HT300 cast iron, square-shaped square box-shaped structure, 20mm wall thickness, and reinforced bars and high-strength cast iron materials optimized by finite element analysis , resin sand molding, full secondary aging and natural aging, so that the basic parts of the machine tool with high rigidity and ensure the stability of the long-term use of the machine tool;
2. The X and Z guide rails adopt the rectangular guide rail structure and are quenched by high frequency. The corresponding slide contact surface is a plastic guide rail, which can obviously reduce the frictional resistance when the guide rail slides and has good dynamic characteristics...
3. The lathe spindle structure is a high-speed, high-precision, high-rigidity shell-type spindle unit. Chromium molybdenum alloy is used as the material of the spindle. The spindle bearings are selected from NSK spindle-dedicated double-row cylindrical roller bearings and P4-class high-speed precision angular contact pairs of bearings. , And use NSK designated high-speed grease, high speed, and high-temperature resistance. The spindle unit is assembled in a constant-temperature room. After assembly, it is continuously operated at a constant temperature for 36 hours. After the machine is turned on, it is tested for 36 consecutive hours to ensure the reliability of high-speed, high-precision performance.
4. Milling spindle adopts high-speed, high-precision, high-rigidity Taiwan Pusen Heavy Duty direct spindle unit, strong axial and radial bearing capacity, the maximum speed up to 10000rpm, the main drive is driven by a servo motor, directly to the spindle ;
5, the use of CNC machine tools four-position tool holder, tool layout and adjustment is more convenient; help to improve the productivity of the machine tool.
6. The X, Z direction feed adopts C3 double nut preloaded precision ball screw. The servo motor is directly connected to the screw through the high torque, low inertia inertial coupling and the screw support adopts the pre-stretching structure. Eliminating the backlash of the drive and compensating for the influence of thermal deformation on the accuracy of the machine during long-term operation to ensure positioning accuracy and repeatability of positioning;
7, X, Z two directions guide rails, screws are used protective devices to ensure that the screw and guide rails clean, ensure the machine's transmission and movement accuracy and life;
8, using a reliable centralized automatic lubrication device, regular, quantitative automatic lubrication of the lubrication points of the machine tool, lubrication time can be adjusted according to the working conditions;
Product Features
Features As Below
The CMK550/2 CNC double feed vertical turning grinding machine developed by our company adopts double-turrets, dual-channel system, and high-power design. The two tool sets can automatically finish turning, grinding inner circle, end face and inverted face at the same time. A variety of processes, such as turning, are widely used in the turning of the various disk and shell parts. Such as car brake disc, hub, brake hub, automobile flywheel, clutch pressure plate, bearing rings, gears and other parts of the rough finish machining, grinding process, the equipment has the following characteristics:
1. High processing efficiency: Due to the double feeding structure, turning and grinding can be achieved at the same time. In addition, the equipment can realize high-speed turning, which greatly improves the processing efficiency, which is 4 to normal lathe processing efficiency. 6 times, while improving the surface quality of the workpiece
2. Roughing car processing: Due to the features of high configuration, high power, high rigidity, etc., the device can complete rough finishing machining of workpieces at one time.
3. Large output power: The device adopts 18.5 kW spindle motor, which provides the guarantee for the realization of large cutting quantity processing of multiple knives.
4. High positioning accuracy: Adopt high-quality linear guide rails and ball screws with large bearing capacity to ensure the positioning accuracy and repeatability of isotropic movement.
5. Stiffness: Due to the use of a reasonable structural layout, the overall structural rigidity of the device is strong, thus ensuring a variety of precision indicators processed at high speeds.
6. Good environmental performance: The fully enclosed structure not only has good safety, but also prevents the splash of dust, greatly improves the working environment, and can also be cooled and cut according to the user's needs.
