4. Centerless grinder: The workpiece is centerless clamped, generally supported between the guide wheel and the bracket, and the guide wheel drives the workpiece to rotate, mainly used in grinding machines for grinding cylindrical surfaces. For example, bearing shaft support, etc.

5. Surface grinder: a grinder mainly used for grinding the plane of the workpiece. a. The hand grinder is suitable for the processing of small size and high precision workpieces, and can process various special-shaped workpieces including arcs, planes, grooves, etc. b. The large water mill is suitable for the processing of larger workpieces, and the processing accuracy is not high, which is different from the hand grinder.

6. Abrasive belt grinder: a grinder that uses a fast-moving abrasive belt for grinding.

7. Honing machine: a grinding machine used for honing various surfaces of workpieces.

12. Special grinder: a special machine tool engaged in grinding certain types of parts. According to its processing objects, it can be divided into: spline shaft grinder, crankshaft grinder, cam grinder, gear grinder, thread grinder, and curve grinder.

13. Creep grinding machine, creep feed grinding is a grinding process, but more importantly, it is not like other forms of grinding. Creep feed grinding is performed by deep cutting and large metal removal, and it is characterized by replacing fast reciprocating motion with a lower feed rate. Creep grinding tools - grinding wheels are like milling cutters deeply buried in the material to be processed.

Why use creep feed grinding?

Because there are certain problems with these other processing techniques. Creep processing has the following advantages:

(1) It has excellent processing characteristics. This grinding process can absorb part of the heat in the machining cutting. Especially in the processing of titanium, Inconel and other materials, it is more effective, mainly because the heat generated during processing will accelerate the wear of the milling cutter or broach;

(2) Maintain a good surface finish. This grinding process does not require particularly high pressure on the machined surface, but the ability to grind the material is high, while maintaining a good surface finish and perfect surface finish quality;

(3) There will be no burrs. Using this grinding process does not require burrs;

(4) The inherent precision can be maintained. Under well-designed process conditions, milling and broaching can achieve high machining accuracy.

The disadvantages of the peristaltic grinder in the prior art are:

1. The traditional peristaltic grinder uses a servo motor with a screw to rotate;

2. The grinding wheel is driven by an ordinary four-phase motor, and the structure of the main shaft is more complicated and there is slight vibration;

3. Most of the traditional peristaltic grinders use manual control of the rotating spindle seat, which cannot adapt to the workpiece with complex processing steps and many rotations.
