Automotive lightweight manufacturing trends increase diamond tool applications

The mechanical processing of modern automobile manufacturing industry and the tool technology used by it have developed rapidly. High-tech has been widely used. In the aspects of machining technology, cutting method, tool structure, tool material, tool coating, etc., it has been much different from the traditional machining in the past. The difference. New tool structures and inserts with new cutting edges and geometries have been continuously researched and developed to accommodate tool holders for CNC machine tools and high-speed machining and their connection to machine tools such as HSK tool holders, hot-sleeve holders, hydraulics Tool holders and other new tool holders are widely used. In order to improve production efficiency and reduce tool change time, various composite tools such as drill collar compound, drill hinge compound, drilling and thread processing compound are used more and more in the processing of automobile parts. The unfolding tool meets many special machining requirements, and some tools have even evolved into a machine, electric and hydraulic integrated device, which has far surpassed the traditional tool concept.

The automotive industry uses large-volume, assembly line production, and the processing conditions are relatively fixed, which imposes very demanding requirements on the processing efficiency, service life and stability of the tool. In recent years, with the large application of lightweight materials in the automotive industry, such as aluminum alloys, composite materials, etc., the application of diamond tools has also increased significantly: as in the processing of some parts of the gearbox housing, the original used carbidesé•—The knife is changed to a diamond tool, and the tool life can be increased to tens of thousands of pieces. The economic benefit is very obvious. Due to their extremely high hardness, diamond tools have a very high service life when processing aluminum workpieces and other non-ferrous metals and their alloys.

Plain HDF/MDF is widely used for furniture, interior decoration and Wood Flooring. With good properties, such as, acid & alkali resistant, heat resistant, easy fabricability, anti-static, easy cleaning, long-service life and no seasonal effect. We provide different sizes an thinkness HDF/MDF Pressing Board, such as 7mm,8mm,10mm,12mm, all are our regular sizes.And also 1220*2440 is our normal specification. For particle board, we provide with 16mm,18mm,25mm, the normal sizes we have. All finishing pressing board can be using for cabinet door, cabinet body,wall plank, various furnatures, which now are very popular in overall furniture manufacture lines.
