  Our LNUX type railway hub turning inserts are adopt imported Dorst machine to ensure good stability of cutting edges and high precision, it produced of imported base material with advanced high precision, which enhances the quality of the inserts, high hardness, great ductility, high finishing, thick coating, stable performance and improves the processing efficiency. The special coating process, fine and smooth, no drip marks, reduce surface friction, so that the cutting resistance is smaller. And the turning inserts are sharp and thick, so that the cutting speed is fast but not easy to break. It also has wide range of application, applicable to step surface processing, model profiling processing, grooving cutting, slope processing, and could to be processed alloy steel, P20 steel, 45# steel, soft steel, carbon steel, medium steel, stainless steel, cast iron, titanium alloy, and etc.,


please send me your requirements to us, we will recommend the best suitable grade.



  Products Detail:


  • Ultrafine grain tungsten steel raw material
  • Reduce resistance, smooth cutting and smooth chip removal
  • Strong deformation resistance and longer services life
  • Non-stick cutter with high durability

1. Railway hub turning inserts shall not be bumped or dropped on the ground and please handle it with care.


2. Before installing the carbide inserts, please confirm the performance and use of operation table, and the cutting direction indicated by the arrow of the blade is consistent with the rotation direction of the operation table. Please pay attention to don't install in the opposite direction. The wrong installation direction may cause the blade serrations to fall off, in case of accidents.


3. After installation, please confirm whether the center hole of the carbide inserts is firmly fixed on the flange of the saw table. If necessary, put on a spacer, then push it lightly by hand to confirm whether the blade rotates eccentrically.


4. When using the inserts, do not exceed the specified high speeds.


5. When not using, please hang the carbide inserts upright on a dry rack.




1. Flank wear: (Common problem)

Effect: Gradual change in workpiece size or loss of surface finish
Reason: Linear speed is too high, and reach to service life of the tool
Measures: Adjust the processing parameters, such as reducing the linear speed and changing to inserts with higher wear resistance


2. Severely broken: 

Effect: sudden and unpredictable occurrence, resulting in scrapped tool holder material or defective workpiece and scrapped
Reason: The processing parameters are set incorrectly, the vibration tool workpiece or the insert is not installed in place
Measures: Set reasonable processing parameters. Reduce the feed rate and cutting, the corresponding machining insert should be selected, and the rigidity of the workpiece and insert should be strengthened.


3. Built-up edge:

Effects: Inconsistent workpiece dimensions and poor surface finish. Fluff or burrs adhere to the workpiece surface
Reason: The cutting speed and the feed is too low, and the blade is not sharp enough
Measures: Increase the cutting speed and use a sharper insert for the feed.


4.Breakdown problem:

Effects: Sudden changes in workpiece size or surface finish, causes sparks and surface burrs
Reason: Inappropriate setting of processing parameters, inappropriate selection of blade material, poor workpiece rigidity, or unstable blade clamping
Measures: Check whether the parameter settings are reasonable, and select the corresponding tool according to the workpiece
