CNC Carbide Small hole inner diameter grooving blade 8GR250 For Cutting Off
Feature Advantage:
- It is the first choice for efficient options of general slotting.
Extremely versatile substrate and coating, suitable for all types of material slotting. It is especially suitable for grooving steel parts.
The perfect edge ensures the quality stability of the blade.
The service life of plug-ins using the same plug-in is longer than that of Korean brands.
The cutting is light, the chip removal is smooth, and the ideal surface quality is achieved. -

Technical information :
Slotting and separation are unique turning applications for many machining applications that require special tools. These tools can be regarded as the extension of ordinary turning to some extent.
Slotting and separating operations should consider three different aspects to determine the best method and mold solution:
Features of parting and grooving workpiece:
Analysis of groove size and quality requirements to be processed: processing type, groove depth, groove width, outer radius and quality requirements.
Workpiece material, shape and quantity.
Whether the material has good chip breaking performance
Production batch: single or batch slotting
Whether the workpiece can be clamped safely
Chip removal
Machine parameters.
Stability, power and torque, especially for large components
Cutting fluid and coolant
Whether the long chip material needs high-pressure coolant to break chips
Speed limit
Use all possible support
Timely replacement of worn blades will make the cost of new blades more economical than that of excessively worn blades.
Replace worn or damaged rods.
Don't try to repair the turret.
1) Front face The surface on which the chip flows on the tool.
2) The surface on the main and back tool face that is opposite to and interacts with the machined surface on the workpiece is called the main and back tool face.
3) The surface on the tool with auxiliary rear tool face that is opposite to and interacts with the machined surface on the workpiece is called auxiliary rear tool face.
4) The intersection line between the rake face and the main rake face of the main cutting edge tool is called the main cutting edge.
5) The intersection line between the rake face and the back face of the auxiliary cutting edge tool is called the auxiliary cutting edge.
6) The intersection point between the main cutting edge and the auxiliary cutting edge of the tool tip is called the tool tip. The tool tip is actually a small segment of curve or line, called rounding tool tip and chamfering tool tip.
Because the production of standard tools is aimed at the cutting of common metal parts or non-metallic parts with a wide range of surfaces, when the hardness of the workpiece is increased due to overheating treatment, or the workpiece is stainless steel, it is very easy to stick to the tool, and there are also some cases where the surface geometry of the workpiece is very complex, or the machined surface has high roughness requirements, the standard tools can not meet the needs of processing. Therefore, in the process of machining, it is necessary to carry out targeted design for the material of the tool, the geometric shape of the edge, the geometric angle, etc., which can be divided into two categories: no need for special customization and need for special customization
