1.75 degree external turning tool

The biggest feature of this turning tool is good tip strength, is the best turning tool tip strength, mainly used for rough turning processing.

2.90 degrees of partial tools

The feature of this turning tool is machining step table. This tools is suitable for coarse and fine turning.

3. Fine turning tool with wide insert

The most remarkable feature of this turning tool is its long polishing edge. Because the strength and rigidity of turning tool head are poor, it is easy to cause the vibration of turning tool if it is thick and thin, so it can only be processed fine turning. The main purpose of this tool is to achieve the surface roughness of the drawing.

4.75 degree end turning tool

Compared with 75 degree external turning tool, the main cutting edge is in the end face direction of the turning tool, and the side is the auxiliary cutting edge. This tool is used for coarse and fine turning of end face cutting.

5. The Parting tools

When grinding the tools, the main attention should be paid to the Angle symmetry of the two auxiliary cutting edges and the main cutting edges, otherwise the cutting force will be unbalanced on both sides, and the tool will be easily damaged when used.

6. Groove turning tool

This tools compared with the cutting tools, its main difference is the requirement of the tool width. The tool width must be grinded according to the drawing width. This tools is used for machining grooves.

7. Thread turning tool

The main characteristic of thread turning tool is the Angle of turning tool grinding. Generally speaking, the Angle of thread turning tool grinding is better than the Angle required by the drawing is less than 1 degree. Thread turning tool processing parts, the main is to install the tools to be positive, otherwise there will be processed thread tooth Angle is correct, but the inverted tooth thread, causing parts processing unqualified.

8.45 degree curved tool

The main feature of this tool is the grinding of the back Angle. When processing the inner chamfering, the back tool surface is not in contact with the wall of the inner hole. This tool is used for inner and outer chamfering.

9. Blocked turning tool

In hole processing, the biggest contradiction encountered by turning tool is that the tool bar is extended longer, and the limit of machining parts hole and the tool bar section is small, but the rigidity is insufficient. When using a hole machining tool, the maximum section of the tool bar allowed by the hole machining should be maximized to increase the rigidity of the tool bar. Otherwise, the machining of the hole will not be rigid enough, and there will be taper and vibration tool. Through hole turning tool is characterized by processing of internal hole step table and through hole, its main deviation Angle is less than 90 degrees, the purpose is to process the end face of the internal hole.

10. Through-hole turning tool

The feature of the through hole turning tool is that the main deflection Angle is greater than 90 degrees, which shows its good tip strength and long service life. Suitable for rough and finish machining through hole.
