  Our MRMN tungsten carbide grooving inserts adopts imported Dorst machine to ensure good stability of cutting edge, high precision, high hardness, good finishing, durable coating, stable performance and improves the working efficiency. MRMN carbide groove insert is made of imported base material with advanced high precision, which enhances the quality of the blade, high hardness, good ductility, high finish, thick coating, stable performance and improves the processing efficiency; Unique coating process, fine and smooth, no drip marks, reduce surface friction, so that the cutting resistance is smaller; High precision blade, effectively reducing friction and loss; The MRMN blade is sharp and thick, so that the cutting speed is fast but not easy to break. It has wide range of application, applicable to step surface processing, model profiling processing, grooving cutting, slope processing, and could to be processed alloy steel, soft steel, carbon steel, medium steel, stainless steel,cast iron, titanium alloy, etc.,


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

1. Carbide MRMN grooving inserts shall not be bumped or dropped on the ground and please be handled with care.


2. Before installing the MRMN carbide grooving blade, 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, it is necessary to confirm whether the center hole of the MRMN carbide grooving blade 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, do not exceed the specified high speed.


5. When not using, please hang the MRMN blades upright on a dry rack.


Common questions:

1. Flank wear: 
Effect: Gradual change in workpiece size into a decrease in surface finish
Reason: the line speed is too high, and the service life of the tool is reached
Measures: Adjust the processing parameters, such as reducing the line speed and changing to inserts with higher wear resistance


⒉Breakdown problem: (bad form of failure)
Effects: Sudden changes in workpiece size or surface finish, resulting in sparking surface burrs
Reason: Inappropriate setting of processing parameters, inappropriate selection of blade material, poor workpiece rigidity, unstable blade clamping
Measures: Check whether the parameter settings are reasonable, and select the corresponding tool according to the workpiece


3. Severely broken: (a very bad form of failure)
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 blade is not installed in place
Measures: Set reasonable processing parameters. The feed rate and cutting should be reduced, the corresponding machining insert should be selected, and the rigidity of the workpiece and insert should be strengthened.
