What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

The heat dissipation effect of the radiator has a great influence.

 The easier way to check the frame is to use the frame gauge. The frame gauge is actually a set of observation needles. During inspection, hang the frame gauges at several different positions on the frame. When using, the three gauges must be used at the same time. The more gauges, the more accurate. If the frame is not deformed, the side needles of the frame gauges should be aligned during the inspection. If the observation needles are not aligned, it means the frame has been deformed. Plate steel plates between the tools as shown in the figure to avoid local stress and deformation. If the frame is accurately inspected, you can use a plumb hammer to draw the frame on the floor. This work must be very precise. The floor must be level and clean. If necessary, paste or nail paper on the floor, and use a plumb hammer in the car. The measurement points on the frame are projected on the ground, and then the distance between the points on the ground is measured by pushing the car away, as shown in the figure. If the frame has been deformed, as long as the amount of error is not large, it is still possible to correct it. The method of calibration varies. Some regulations must be calibrated in a cold state, the reason is that heating will weaken the strength of the frame. There are also suggestions for heating and correcting the frame, but the temperature should not exceed the dark red at this time. Hard work at this temperature will reduce the strength of the frame material and cause permanent damage. Especially the components that have undergone heat treatment, pay more attention to it. When heating, the heating area should be minimized, and attention should be paid to slow cooling. So as not to make the material brittle. Usually an oxygen-acetylene flame is used to heat the frame. It is also necessary to use some straightening tools, such as a thick I-shaped beam connecting the I-shaped beam and the frame of the chain to apply pressure to the chain to correct the pressure of the jack, or special topping tools made of screws, etc. The pre-compression should be correctly selected when correcting the frame. Location. And in the frame and correction, if the frame is severely deformed or broken, the frame needs to be replaced.
