The existence of backlash will affect the positioning accuracy and repeat positioning accuracy of the CNC machining center, thereby affecting the processing accuracy of the product. This requires the digital frustration system to provide a backlash compensation function to automatically compensate for some problems during processing. Regular errors can improve the accuracy of processed parts. …

Numerical control machining centers are divided into boring and milling and turning according to their processing procedures, and can be divided into three-axis, four-axis and five-axis machining centers according to the number of control axes. 1, boring and milling machining center The tool magazine and automatic tool changer are the main differences between machining centers …
Since the advent of cnc machining center, various types have appeared. Although the appearance and structure are different, the seven parts are composed of the following parts: Basic components. Composed of large parts such as the bed, column and worktable, it is the basic component of the CNC machining center. They can be cast iron …
Horizontal CNC boring and milling machines with automatic tool changer are collectively referred to as horizontal CNC machining centers. Horizontal CNC machining center is a kind of automatic processing equipment developed on the basis of CNC boring and milling machine. It can realize one-time clamping and multi-process processing through automatic tool change. The machine has …
For processing on a machining center, the division of the processing stage is mainly determined according to the accuracy requirements of the workpiece, and also needs to consider factors such as production batch size, blank quality, and processing conditions of the machining center. (1) If the part has been roughed, the machining center only completes …
Processing parts on a machining center generally has multiple steps and multiple tools are used. Therefore, whether the processing sequence is reasonable or not directly affects the processing accuracy, processing efficiency, number of tools and economic benefits. (1) When arranging the processing sequence, the general process principles of “base surface first, surface first, hole first”, …
Why do machining center bed castings need aging treatment: In order to make the bed castings have the required mechanical properties, physical properties and chemical properties, in addition to the reasonable selection of materials and various forming processes, heat treatment processes are indispensable. Steel is the most widely used material in the machinery industry. The …
