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

How to Ensure the Precision of CNC Machining Parts?

Keywords:Cnc Machining parts,How to ensure the accuracy of CNC machining parts?

For many non-standard parts processing customers, the most concerned is the machining accuracy of CNC machining parts when selecting suppliers.It is easy to find suppliers for the precision processing industry in Shenzhen, but it is difficult to find the processing points with higher accuracy, and we must be careful.In short, there is a risk to accuracy and careful processing.

For machining centers with no standard parts, more tools are usually required.In order to ensure the machining accuracy of CNC machining parts, the replacement sequence of cutting tools should be reasonably arranged.Replacement of processing tools should be carried out in accordance with the processing sequence, the general process principle is that the first datum, and then drilling, first rough after fine.

For the machining of precision mechanical parts, the machining of datum surface is optimal, which provides the positioning basis for the machining of other surfaces.The process positioning benchmark is the benchmark of the next process positioning.Therefore, when the non-standard parts are processed, the whole processing process can be pushed forward and backward after determining the positioning datum of each procedure.

Determining whether non-standard parts need to be machined or not is to determine the machining sequence of CNC machining parts.It is also usually carried out by means of CNC lathes.If the coarse precision of the workpiece is high, the positioning is also guaranteed, or the processing amount is sufficient, it can be processed directly in the processing center without preprocessing.In this process, the coarse datum accuracy and process differences between machining centers need to be considered, and the final may be several or one process.

Similarly, if the pretreatment surface and the processing center operating surface have different standard requirements, the pretreatment should reserve enough processing margin.At the end of a single clamping process for a non-standard CNC machining center, all machining elements, including the pre-machined surface, must be included to ensure the final precision machining accuracy.
