Comprehensive Comparison of Material Properties of Milling Tools

1. The order of hardness of tool materials: PCD>PCBN>A1, O, based ceramics>Si, N, based ceramics>TiC (N) based carbide>WC based ultrafine grained carbide>High speed steel (HSS) 2. The order of bending strength of tool materials is HSS>WC-based cemented carbide>TiC(N)-based cemented carbide>Si, N-based ceramics>A1,0:-based ceramics>PCD>PCBN 3. The order of fracture toughness of tool materials is HSS>WC-based cemented […]

In order to let everyone better understand the meaning of each letter of the boring tool specification, we have made this table with detailed examples. We hope it will be helpful for everyone to understand the boring tool. If you have any questions, please contact us. All specifications can be customized. Example:    MTR-1-RO.05-L4 M […]

High-performance high-speed steel refers to a new steel type that adds alloy elements such as carbon, vanadium, cobalt or aluminum to general-purpose high-speed steel. 1. High-carbon high-speed steel has a carbon content that is 0.20% to 0.25% higher than that of similar general-purpose high-speed steel, causing all the alloying elements in the steel to form […]

Ordinary high-speed steel is divided into tungsten-based high-speed steel and tungsten-molybdenum-based high-speed steel. 1. Tungsten-based high-speed steel (W18 for short) contains less vanadium and has good sharpening processability. The tendency of overheating during fire is small, and heat treatment control is easier. The steel grinding performance and comprehensive performance are good, and the versatility is […]

In practice, in order to judge the wear of the tool more conveniently, accurately and intuitively, the tool life is generally used to indirectly reflect the bluntness of the tool. The cutting time of a sharpened tool from the start of cutting until the wear amount reaches the blunt standard is called tool life, and […]

Better not to do that! Because the T-shaped cutter does not have a spiral chip flute, the chips cannot be discharged smoothly when grooving, and the cutter can easily break! Besides, the cutting performance of forming tools is not as good as that of end mills, they are just relatively convenient! It is recommended to […]

1. First correct the position of the workpiece to ensure that the T-shaped groove is consistent with the feed direction of the workbench. 2. Use a dial indicator to correct the position of the upper plane of the workpiece to ensure it is parallel to the work surface. 3. Follow the steps to use the […]

The speed of tapping depends on the type of screw tap, the number of teeth of the tapping part, the material, the type of material to be cut, the shape of the bottom hole, the cutting oil, etc. The speed is adjusted under the speed setting, so it must be very careful. Notice. When the […]
