The busbar processing machine is widely used in processing various specifications of copper and aluminum busbars. It is easy to use and has a significantly higher production efficiency.
There will be casters on the machine, which can be moved easily.
The traditional busbar processing equipment has greatly improved the production efficiency. The busbar processing machine is difficult to avoid errors when it realizes the punching, shearing and bending operations. In order to improve the processing accuracy, measures are taken to minimize the errors. The following is an introduction to the method of reducing the error of the busbar processing machine:
1. Hot oil cleaning method: The bearings hardened by soft dry oil or anti-rust paste should be immersed in hot oil at 100-200 ℃, clamp the bearing with pliers, and use a brush to clean the oil on the bearing. Soft dry oil or anti-rust paste is heated to 100-200 ℃ to melt, and it is very easy to wash out from the gap of the bearing. Sometimes it is only necessary to shake the bearing several times in the oil. Oil stains will also run away from the crevices. When cleaning the old busbar processing machine motor or the radial spherical bearing of the imported motor, the balls, the ball carrier and the inner ring should be rotated laterally from the outer ring and then immersed in hot oil. The short cylindrical roller bearing should also be cleaned when cleaning. The rollers, ball carrier, inner and outer rings should be disengaged. During hot oil cleaning, the temperature of the oil should not exceed 20°C. If direct heating with an open flame, attention should be paid to avoid burning the oil. The bearing should be suspended in the oil pan and sinking to the bottom will cause overheating and reduce hardness.
1. The influence of the repeated positioning accuracy of the machine tool: The positioning accuracy of the busbar processing machine is the position accuracy of the coordinate axes of the index control machine tool under the control of the system. The factors that cause the positioning error include the system error and the mechanical transmission error. The error is related to the interpolation error, tracking error, etc. The repeated positioning accuracy of the busbar processing machine refers to the degree of conformity between the actual position and the ideal position of the coordinate axis during repeated positioning.
2. Do more comparisons. When choosing a CNC busbar processing machine, be sure to shop around. There are many manufacturers of CNC bus processing machines, which affect people's choices to a certain extent. In the selection process, don't be in a hurry, you can compare prices, performance, features, etc. to understand the general situation, so that you will have a good judgment.

d. The three-phase power supply entering the CNC machine tool should adopt a three-phase five-wire system, and the neutral line (N) and the grounding (PE) are strictly separated.
2. Influence of tool error: In processing, because the tool used has automatic exchange function, it also brings tool exchange error while improving productivity. When using the same tool to process a batch of workpieces, due to the frequent and repeated tool change, the tool holder has a repeated positioning error relative to the spindle taper hole, which reduces the machining accuracy.
3. The influence of the detection device: The detection feedback device is also called the feedback element, which is usually installed on the workbench or the lead screw of the busbar processing machine. The detection feedback device converts the displacement of the worktable into an electrical signal and feeds it back to the numerical control device. If there is an error in the command value, the control table moves in the direction of eliminating the error. The numerical control system can be divided into open-loop, closed-loop and semi-closed-loop systems according to the presence or absence of detection devices. The accuracy of the open-loop system depends on the accuracy of the stepper motor and the lead screw, and the accuracy of the closed-loop system depends on the accuracy of the detection device. The detection device is an important part of the high-performance busbar processing machine.
