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

High precision plastic mold processing steps

High-precision plastic mold processing steps 1. Heating and pre-plasticizing:
Driven by the drive system, the screw conveys and compacts the material from the hopper. Under the combined action of the heater, screw and barrel outside the barrel, the material is gradually melted, and the material is gradually melted at the head of the barrel. The part has accumulated a certain amount of molten plastic machining. Under the pressure of the melt, the screw slowly retreats. The retreat distance depends on the amount required for one injection of the metering device to adjust. When the predetermined injection volume is reached, the screw stops rotating and retreats .


2. Mold clamping and locking:
The clamping mechanism pushes the mold plate and the movable mold part of the mold installed on the movable mold plate to close and lock the mold part on the movable mold plate to ensure that sufficient clamping force is provided to lock the mold during forming.
3. Move the injection device forward:
When the mold clamping is completed, the entire injection seat is pushed and moved forward, so that the nozzle of the injection machine and the main runner of the mold are completely fitted.
4. Injection and pressure maintaining:
After the clamping and nozzle are fully fitted to the mold, the injection hydraulic cylinder enters high-pressure oil, pushing the screw forward relative to the barrel, and injecting the melt accumulated in the head of the barrel into the cavity of the mold with sufficient pressure, which is caused by the decrease in temperature. To shrink the volume of the plastic machining china, in order to ensure the compactness, dimensional accuracy and mechanical properties of the plastic part, it is necessary to maintain a certain pressure on the melt in the mold cavity to supplement the material.
5. Pressure relief:
When the melt at the gate of the high-precision china cnc machining plastic mold freezes, the pressure can be relieved.
6. Retreat of the injection device:
Generally speaking, after the pressure relief is completed, the screw can rotate and retreat to complete the next feeding and pre-plasticizing process. (Under the general situation of existing injection molding, the movement of the injection seat to withdraw the main gate of the mold has been cancelled. (Perform this action when molding materials with serious salivation, such as PA).
7. Open the mold and eject the plastic parts
After the plastic part in the cavity of the high-precision plastic mold is cooled and shaped, the clamping mechanism opens the mold and pushes out the plastic part in the mold.
