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

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

The configuration method of the spindle bearing of the CNC machining machine tool

The configuration method of the spindle bearing of the CNC machining machine tool

 

Generally, the spindle components of medium and small CNC machining machine tools mostly use rolling bearings (bearing) as the spindle support. At present, there are mainly the following three deployment methods:

 

1. The front support adopts double row short cylindrical rollers

 

Bearing and 60. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and letters, and the processing required by the manufacturing technology. It generally refers to the process of processing parts on CNC machine tools. In order to improve the degree of production automation, shorten the programming time and reduce the cost of CNC machining, a series of advanced CNC machining technologies have been developed and used in the aerospace industry. Angular contact double row radial thrust ball bearing combination, the rear support adopts radial thrust ball bearing. This configuration (deploy) method greatly improves the comprehensive rigidity of the spindle, which can meet the requirements of powerful cutting, and is widely used in the spindle of various CNC machine tools (attributes: automated machine tools). The rear bearing of this configuration can also adopt a cylindrical roller bearing to further improve the radial rigidity of the rear support.

 

2. The front support adopts high-precision (precision) double row direction

 

Heart thrust ball bearings (bearing). In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and letters, and the processing required by the processing technology. It generally refers to the process of casting alloy parts on CNC machine tools. In order to improve the degree of production automation, shorten the programming time and reduce the cost of CNC machining, a series of advanced CNC machining technologies have been developed and used in the aerospace industry. ?Numerical control machine tool (attribute: automated machine tool) spindle bearing configuration (deploy)? Centripetal thrust ball bearing has good high-speed performance, the maximum speed of the spindle can reach 4000r/min, but its load capacity is small, only suitable for high-speed, light load And precision (precise) CNC machine tool spindle. In order to improve the rigidity of the main shaft in this deployment mode, the front support can be combined with four or more bearings, and the rear support can be combined with two bearings.

 

3. The front and rear bearings (bearing) adopt double-row and single-row tapered roller bearings. This type of bearing can withstand large radial and axial forces, so that the spindle can withstand heavy loads, especially strong dynamic loads, with good rigidity, and installation and Good debugging performance. CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining boring and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. However, this configuration (deploy) limits the maximum speed and accuracy (precision) of the spindle, and is only suitable for the spindles of medium-precision, low-speed and heavy-duty CNC machine tools (attributes: automated machine tools).
