What should be paid attention to during the machining operation of the tube sheet drill bit

In the whole process of tube sheet hole processing, tube sheet drill bit processing manufacturers need to pay attention to which are super heavy machinery plants, often encounter parts tube sheet hole processing. Before processing, it is necessary to master several common problems of tube sheet drill bit processing manufacturers. Only by knowing such things can the work be done better and some problems can be avoided when machining the tube sheet drill bit. So, let's learn what to pay attention to during the processing of the lower tube plate drill bit!

What milling cutter should be selected for processing high hardness materials?

What milling cutter should be selected for processing high hardness materials?

With the continuous development of manufacturing industry, the application of difficult-to-process materials with high hardness, high wear resistance, high heat resistance and high chemical stability is increasing. In order to solve the problem of poor processing performance and difficult processing of difficult material parts, various new types of cutting tools such as carbide coated cutting tools, diamond, ceramics, cubic boron nitride and other superhard cutting tools are becoming more and more widely used. Through further theoretical research and processing practice, it is proved that the selection of suitable tool material, the determination of reasonable tool geometry parameters, the optimization and improvement of tool structure, and the selection of correct processing methods are effective ways to improve the processing efficiency of high hardness materials.

How should CNC machining tools be selected in machining?

How should CNC machining tools be selected in machining?

Generally speaking, CNC equipment mainly refers to large CNC machining lathes and machining centers. The machining center is a highly electromechanical product. After the workpiece is clamped, the numerical control system can control the machine tool to automatically select and replace tools according to different processes, automatically set tools, automatically change the spindle speed, feed rate, etc., and can continuously complete drilling, boring, milling, reaming, tapping and other processes. Machining center refers to a CNC machine tool equipped with a tool magazine, with automatic tool change function, and multi-process processing after a workpiece is clamped. Thus greatly reducing the workpiece clamping time, measurement and machine tool adjustment and other auxiliary process time, the processing shape is more complex, high precision requirements, the variety of frequent replacement of parts has a good economic effect.

How to ensure the machining accuracy in machining?

How to ensure the machining accuracy in machining?

When it comes to milling, it can be regarded as an important way in the field of aviation manufacturing. As we all know, it is generally expected to improve the material removal rate in the machining process. Traditional milling methods usually increase the tool meshing angle to meet the requirements of material removal rate. However, this will inevitably lead to long contact time between the tool and the workpiece, and the increase of cutting temperature, which will affect the service life of the tool.

What milling cutter should be selected for processing high hardness materials?

High-speed machining (high-speed cutting, HSC) is an important part of advanced manufacturing technology, its main advantage is to achieve high efficiency and high quality processing. In recent years, high-speed machining technology in the world's major economically developed countries (such as Germany, Britain, the United States, Italy, Japan, etc.) has developed rapidly. The high-speed cutting machine tools and auxiliary, matching, software and hardware produced by these countries are almost updated at a new level every year. At present, the performance indicators that can be achieved are eye-popping. Micron, Jobs, Haas, Fpt, Dmg and other world-famous machine tool companies have vigorously developed the technology of rapidly replacing spindle heads in recent years, which enables the same machine tool to adapt to various load and speed requirements (the so-called "one-time pass" of the same machine for rough finishing), and can save a lot of non-processing time in the positioning, installation and transmission of workpieces. The high-speed rotation of the machine tool spindle and the corresponding increase in feed speed and acceleration, on the one hand, can directly shorten the processing time, on the other hand, because high-speed cutting has the advantages of particularly high excitation frequency, stable work and small vibration, it is beneficial to improve the processing surface quality, that is, high-speed cutting can be used as the final processing of molds and structural parts, through "cutting instead of grinding" or "cutting instead of discharge" to improve the processing efficiency and processing quality (that is, do not need to carry out time-consuming and inefficient follow-up grinding process, die electrode EDM); The workpiece can also be quenched before cutting, and the material with hardness up to 65HRC can be directly processed to the final size at high speed.
