Automatic CNC Milling Machine for T70B T90B T140B Elevator Guide Rails
CNC Milling Machine Overview
1. This machine tool is designed and manufactured by our company according to the processing requirements and processing technology of the T70B ~ T140B elevator guide rail, which is specially used for the processing of the end faces and large back faces of the elevator guide rail.
2. The machine tool is driven by servo motor and ball screw. All the movements use PLC automatic control. It can guarantee the automatic control of fast forward, milling end, fast forward, fast forward and milling back to the end, and return to the original point quickly. The touch screen is easy to understand and easy to adjust.
3. The guide rail of machine tool is lubricated by automatic lubricating pump to reduce wear and improve the service life of machine tools. The ball screw of machine tool is lubricated by the way of soaking in the lubricating oil. All necessary safety protection devices and protective covers are provided to ensure the safety of operators and machine tools.

Main Structure and Technical Characteristics
1. Power head components
The machine tool uses two 1tx32 power heads to mill the end face and the large back face of the elevator guide rail, first milling the end face and then milling the large back face. 1tx32 power head has the characteristics of large transmission torque, reasonable structure, low noise and low maintenance rate. The internal gear is helical gear, all of which have been quenched and grinded. The motor model on the power head at the back of milling machine is 7.5kW, grade 4, and the motor model on the power head at the end of milling machine is 5.5kW, grade 6. The factory configuration speed is 630 rpm, and the factory configuration is Φ 200mm cutter head.
2. Bed table parts
The bed table is made of high-quality cast iron, and the bed guide rail is in the form of "one mountain, one flat". The stress and guidance of the guide rail in this form are relatively good, and the guide rail surface of the bed is grinded. The guide rail surface of the worktable is pasted with plastic, which has good wear resistance and repairability.
The workbench is driven by servo motor and ball screw, and the stroke and speed are controlled by PLC.
3. Fixture part
The clamp is mounted on the side seat of the table, and is clamped up and down and left and right by two hydraulic cylinders. The clamping pressure is generally 3Mpa.
The clamping principle is as follows: 1. The left and right clamping cylinders clamp the guide rail with relative low pressure, and then centralize the guide rail; 2. The upper and lower clamping cylinders press the guide rail with high pressure; 3. The left and right cylinders pressurize, so that the left and right cylinders clamp the guide rail with high pressure. Clamping the guide rail in these steps can make the guide rail fit the datum plane to the greatest extent, so as to eliminate the clamping error.
4. Chip removal part
The chip removing part is installed between the bed and the fixture, and the screw chip removing machine is used to discharge the iron chips from the chip removing port at the end of the bed to the chip holding car, which avoids the previous work of cleaning the iron chips.
5. Lubrication system
The lubrication of the guide rail of the machine tool bed is realized by the automatic lubrication pump installed at one end, which is automatically lubricated when the machine is started. Ball screw is lubricated by immersion oil, which is reliable. The lubrication of the power head gear is lubricated by the lubricating oil stored in the power head gear box, and the lubricating oil needs to be changed regularly.
6. Electrical Control: PLC
This machine tool is controlled by PLC, and PLC is made by Mitsubishi brand of Japan. Guangzhou CNC products are selected for servo motor and driver, and Schneider brand products are selected for other main low-voltage components.
