Briefly describe the characteristics of milling and the classification of cutting tools

Milling characteristics: the milling cutter is a kind of multi edge cutter, which has a large number of working teeth. It can be stepped milling or high-speed milling, so the production rate is high. Milling process is a continuous cutting process.

Why is the new tool material so perfect?

In order to ensure a more stable cutting action in the entire flow area, the groove shape and size at the cutting edge have been customized. A new breakthrough has been made in the microstructure of alumina coating by chemical vapor deposition (CVD). The edge line has better toughness and more wear resistance, especially suitable for intermittent cutting, thanks to the newly developed post-treatment process to a large extent.

New Breakthrough in Tool Material Development

Steel turning is one of the major fields of processing. Almost all workshops have this process, which means that steel parts can be applied regardless of material type, workpiece type, process type and batch size. This is mainly used for parts processing in the application range of ISO P25.

Do you know what problems should be considered when selecting NC blades?

(1) The type, specification and accuracy grade of NC blade shall meet the processing requirements, and the blade material shall be compatible with the workpiece material. (2) Good cutting performance. In order to adapt to the use of large back feed and high feed when rough machining or machining difficult to machine materials, the blade must be able to withstand high-speed cutting and cutting. At the same time, the cutting performance and blade life of the same batch of blades must be stable, so that the tool can be changed according to the blade life or the blade life can be managed by the CNC system.

What are the processing precautions of alloy milling cutter manufacturers?

Alloy milling cutter is a kind of cutter with a blade similar to a ball head, which is assembled on a milling machine to mill various curved surfaces and arc grooves. Ball end milling cutter is also called R cutter. Ball end milling cutter, capable of semi precision milling and precision milling of curved surface; Small ball end milling cutter can not only finish milling small chamfers of steep surfaces/straight walls, but also finish milling irregular contour surfaces.

Methods to prevent milling cutter wear

The design manufacturer of the forming tool said that the basic wear law of the milling tool is similar to that of the turning tool. The cutting thickness of high-speed tungsten steel milling cutter is relatively small, especially in up milling, the cutter teeth extrude and slide severely on the surface of the workpiece, so the milling cutter wear will occur behind. When milling steel parts with tungsten steel face milling cutter, due to the high cutting speed, the chip sliding speed along the front is high, so the rear is worn together, and the front is also worn slightly.

How to grind the end milling cutter correctly?

The end milling cutter is a machine tool tool, which is usually used in horizontal milling. Its outer circle and the two end faces close to the outer circle have cutting edges, so it is called a three sided edge. The one with inserted teeth has an integral one. W18Cr4V is commonly used as the material, and there are nearly 100 kinds of specifications according to the diameter and width (thickness). When in use, the cutter is installed on the cutter bar of horizontal milling, and of course, it can also be installed on other machine tools, generally used for milling grooves and steps.

Chip removal mode of deep hole cutter

深孔刀具由于采用内排屑工作方式,供油从镗杆外部供入,经过导条和切削刃后,折回头从镗杆空腔携带切屑向后排出,实现了镗头切削刃和导条的充分冷却润滑。在此基础上,可进一步自由地采用超硬刀具材料制造切削刃和导条,以实现高速高精度的深孔镗削。

Development of tungsten steel tool industry

With the continuous development of tungsten steel tool industry in China, the demand and requirements of hardware tool factories for mold products are gradually increasing. The domestic market has a growing demand for medium and fine molds. The development of household appliances, automobiles, and plastic products industries has also put forward higher requirements for mold tools, thus providing a broad market space for China's mold tool industry.

What are the factors that affect the service life of forming tools?

Linear velocity has a great influence on tool life. If the linear speed is 20% higher than the specified linear speed of the sample, the tool life will be reduced to 1/2 of the original; If it is increased to 50%, the tool life will be only 1/5 of the original. To improve the service life of the tool, it is necessary to know the material and state of each type of workpiece to be machined and the linear speed range of the selected tool.
