Features of VMC850 CNC equipment for processing and manufacturing automotive brake pads:
1. The main foundation components such as the base, slide, worktable, column, and spindle box are made of high rigidity cast iron structure, with reinforcing ribs distributed inside the base. The slide is a box type structure, ensuring the high rigidity and bending and shock absorption performance of the foundation components. The column adopts a column structure, with a stable foundation and good rigidity; The basic components are molded with resin sand and undergo aging treatment to ensure the stability of the long-term accuracy of the machine tool, providing a guarantee for the stability of the machine tool performance.
2. The X, Y, and Z-direction guide rail pairs are made of British made plastic, which has good wear resistance and precision retention. Cooperate with automatic forced lubrication to achieve non crawling motion of the machine tool.
3. High precision and high-strength ball screws are used for feeding in the X, Y, and Z directions, with a high feed speed; The drive motor is directly connected to the screw through an elastic coupling, and the feed servo motor directly transmits power to the high-precision ball screw without backlash, ensuring the positioning accuracy of the machine tool;
4. Adopting high-speed, high-precision, and high rigidity spindle units, with strong axial and radial bearing capacity, and a speed of up to 8000rpm;
5. The X, Y, and Z direction guide rails and lead screws are all enclosed and protected to ensure the cleanliness of the lead screws and guide rails, and to ensure the transmission and motion accuracy of the machine tool;
6. The external protection of the machine tool adopts a fully enclosed structure design, which is safe and reliable;
7. Adopting centralized automatic lubrication device, timed and quantitative automatic intermittent lubrication, stable and reliable operation;
8. Electrical components are selected from well-known brands. (Siemens or Schneider is selected as the intermediate relay.)
9. Accuracy
The precision shall be manufactured and accepted in accordance with JB/T8771.2-1998 "Inspection Conditions for Machining Centers Part 2: Geometric Accuracy Inspection of Vertical Machining Centers" and JB/T8771.4-1998 "Inspection Conditions for Machining Centers Part 4: Positioning Accuracy and Repetitive Positioning Accuracy Inspection of Linear and Rotary Axes".
The positioning accuracy can reach:± The repeated positioning accuracy of 0.015 can reach:± zero point zero one
10. CNC control system (standard configuration)
The system has complete and reliable interlocking, safety protection, and fault diagnosis alarm functions, equipped with RS232 standard communication interface and CF card, and can achieve DNC processing.
