Machining is the process of machining parts and components to improve the overall size of the workpiece or change the performance. Many people pay more attention to the development of the machining industry. Therefore, in response to this problem, the editor will analyze the current situation and future of the machining industry. Development trend.

In precision parts processing, the path of the tool position relative to the movement of the part is called the processing path. The processing routes are as follows. Hole processing route: The hole processing route refers to the distance between the tool tip position and the upper surface of the hole when the tool is switched from fast forward to work during the hole processing. The machining route of the hole system with high mutual position accuracy.

Severe tool wear makes it difficult to regrind and affects the processing quality of precision parts. Due to different workpiece materials and different cutting materials, the normal wear of the tool has the following three conditions: 1. Flank wear Flank wear only occurs on the flank surface. After abrasion, an edge surface with αo ≤ 0o is formed. Its height VB represents the amount of wear.

Commonly used drills for precision parts processing include center drills, standard twist drills, reamer drills, deep hole drills and counter hole drills. Center drill: Mainly used for hole positioning. Due to the small diameter of the cut part, a higher speed should be selected when center drills are used to drill holes. Standard twist drill: The cutting part of the twist drill includes two main cutting edges, two auxiliary cutting edges, one chisel edge and two spiral flutes.

n order to meet the processing requirements of precision parts of CNC lathes, CNC machine tools have many performance requirements for the tools used. Compared with the tools of ordinary machine tools, CNC lathe tools and tool systems have the following characteristics: 1. Generalization, regularization and serialization of blades or knives. 2. Standardization and typification of insert or tool geometric parameters and cutting parameters. 3. The blade or tool material and cutting parameters must match the material of the workpiece to be processed 4.

The structural manufacturability of precision parts processing refers to the requirements for the design of the parts according to the characteristics of the processing technology, that is, the structural design of the parts will affect or determine the quality of the processing. It can be analyzed from the aspects of processing feasibility, convenience and economy. (1) Analysis from the correct mark of the part drawin

When processing deep-hole workpieces for precision parts, because the tool holder is limited by the aperture and depth of the hole, this requires the tool holder to be slender, but the slender tool holder will cause its rigidity to be poor, and it is prone to vibration and tool letting when turning. . Due to the depth of the hole, during drilling, the drill bit is easy to deflect and cause the axis of the hole to be skewed; due to the depth of the hole,
