Product Description: Milling cutters are used for milling operations and are rotary tools with one or more teeth. Mainly used for machining planes, steps, grooves, forming surfaces, and cutting workpieces on milling machines.
Application industry: Auto parts processing, Aerospace, Electronic processing, Graphite processing, etc.
What is PCD?
Polycrystalline diamond PCD (Polycrystalline Diamond) is a synthetic diamond tool material, which is used for processing wood, plastic, and metal. This material is favored mainly due to its high hardness and good wear resistance. Therefore, the characteristics of PCD tools are long service life, fast cutting speed, continuous and stable quality, etc.
Application of milling cutter
A milling cutter is a rotary tool with one or more teeth for milling. When working, each cutter tooth cuts off the allowance of the workpiece in turn. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces and cutting workpieces on milling machines.
What material is PCD milling cutter suitable for?
The pcd milling cutter can process non-ferrous metal materials and non-metal materials, such as non-ferrous metals: aluminum, aluminum alloy, aluminum cast alloy, copper, copper alloy, zinc, zinc alloy and other materials; Non-metallic materials: graphite, carbon fiber composite materials, glass fiber materials, new composite materials and other materials processing.
Types of PCD Milling Tools
Cylindrical milling cutter
For machining planes on horizontal milling machines. The cutter teeth are distributed on the circumference of the milling cutter and are divided into two types: straight teeth and spiral teeth according to the tooth shape. According to the number of teeth, there are two kinds of coarse teeth and fine teeth. The helical-tooth coarse-tooth milling cutter has few teeth, high tooth strength, and large chip space, which is suitable for rough machining; the fine-toothed milling cutter is suitable for finishing.
Face milling cutter
Also known as a disc milling cutter, it is used for machining planes on vertical milling machines, face milling machines, or gantry milling machines. There are cutter teeth on the end face and circumference, as well as coarse teeth and fine teeth. Its structure has three types: integral type, insert type, and indexable type.
It is used for processing grooves and stepped surfaces, etc. The cutter teeth are on the circumference and end face, and cannot be fed in the axial direction during operation. Axial feed is possible when the end mill has end teeth that pass through the center.
Three-sided edge milling cutter
It is used to process various grooves and stepped surfaces, and there are cutter teeth on both sides and the circumference.
Advantages of PCD milling cutters
(1)The service life of the tool is super long, which is 20-100 times that of the ordinary alloy tool, which saves the time occupied by frequent tool changing and tool setting;
(2) Suitable for high-efficiency machining, suitable for high-speed (8000-40000 rpm), dry machining, is the first choice for modern high-efficiency machining, and does not require cutting fluid, environmentally friendly and reliable;
(3) The parts are dimensionally stable after machining and have high surface roughness. Due to the super wear resistance of PCD materials, the tool can ensure that the dimensions of the parts remain unchanged during the process of machining the parts, and the size and shape tolerances of the processed workpieces are guaranteed. The roughness of products processed with PCD milling cutters can reach Ra0.8-Ra0.16, which can completely replace the traditional grinding process with milling, which greatly improves the processing efficiency and processing cost!
Application areas of PCD milling cutters
Auto Parts Processing Industry
To reduce the weight of the car body in the automotive industry, there are more and more applications of aluminum, such as automotive cylinders, cylinder blocks, cylinder heads, etc.
Aerospace Processing Industry
The ideal material for aerospace wings: new composite materials have the characteristics of lightweight, high strength, high-temperature resistance, and corrosion resistance compared with other materials. How to carry out efficient and high-quality cutting processing is a very important issue. The main tools for processing these materials are cemented carbide and superhard tool materials, and PCD milling cutters can naturally be processed as one of the superhard tools.
Electronic Processing Industry
In the 3C electronics industry, a large number of aluminum materials are used in the production process. Moreover, to obtain a good feel, the final surface treatment of the shell of communication products is sprayed with fine sand and then anodized, such as mobile phone shell, notebook computer shell, and so on.
Graphite Processing Industry
In terms of graphite processing, some graphite parts can also be processed with PCD milling cutters, which also have a longer service life than ordinary tools.
Regrinding of PCD Milling Tools
Only need to regrind the cutting edge, no new raw material is needed, which can save cost, and also to protect the environment and recycle the non-renewable resources. Project PCD Grinding from MORESUPERHARD supply provide regrinding/resharpening service for PCD/CBN/ND/CVD/MCD tools, especially for complex tools which is edge broken or not sharp.
