Coordinate system of surface grinder

1. cylindrical grinder: it is a common basic series, mainly used for grinding the outer surfaces of cylinders and cones.

2. Internal grinder: it is a common basic series, mainly used for grinding the internal surfaces of cylinders and cones. In addition, there are grinders for grinding internal and external circles.

Coordinate grinder: Internal grinder with precise coordinate positioning device.

Centerless grinder: The workpiece is held centerless and generally supported between the guide wheel and the bracket. The guide wheel drives the workpiece to rotate, which is mainly used for grinding cylindrical surfaces. Such as bearing shaft support.

5. Surface grinder: a grinder mainly used for grinding the workpiece plane. Manual grinding machine is suitable for machining workpieces with small size and high precision, and can process all kinds of irregular workpieces, including cambered surfaces, planes and grooves. B. Large water mill is suitable for processing larger workpieces, and the processing accuracy is not high, which is different from hand mill.

Belt grinder: a grinder that grinds with a fast-moving belt.

Honing machine: it is mainly used to process various cylindrical holes (including smooth holes, axial or radial discontinuous faces, through holes, blind holes and multi-step holes), as well as conical holes, elliptical holes and trochoid holes. Grinder: a grinder used to grind the plane or cylindrical inner and outer surfaces of workpieces.

9. Guide grinder: a grinder mainly used for grinding the guide surface of machine tools.

X. Tool grinder: a grinder for grinding tools.

1 1. Multi-purpose grinder: a grinder used for grinding cylindrical and conical inner and outer surfaces or planes, with follow-up devices and accessories for grinding various workpieces.

Special grinder: a special machine tool for grinding some parts. According to its processing objects, it can be divided into spline shaft grinder, crankshaft grinder, cam grinder, gear grinder, thread grinder, curve grinder and so on.

13. end grinder: a grinder used to grind the end face of gears.

Extended data:

Grinders can process materials with high hardness, such as hardened steel and cemented carbide. It can also process brittle materials, such as glass and granite. The grinder can have high grinding accuracy, small surface roughness and high grinding efficiency, such as strong grinding.

The grinding machine and grinding wheel motor used in standard machining work according to the traditional starting circuit. After the motor is started, run at the rated speed. Due to the fluctuation of grid voltage and the constant change of friction load of grinding wheel workpiece, the speed error of motor will be affected.

The starting circuit of standard grinding wheel motor generally has only one machining speed, which is difficult to adapt to the different relative linear speeds of different workpiece sizes, thus it is difficult to ensure the machining accuracy of the machined workpiece. Therefore, from the aspects of improving machining quality, machining efficiency and saving energy, the application of variable frequency speed regulation technology to grinding machines can achieve satisfactory results.
