grinder and two point motion control requirements of common types

What are the common types of grinders? According to the motion characteristics and process requirements of the grinder, what are the requirements for its electric drive and control? The purpose of putting forward these two questions about grinder is to solve them well so that we can understand them clearly and grasp them firmly.

1. What are the common types of grinders?

The specific answer to this question is as follows:

Internal grinder: This is the basic type of the common grinder, mainly used for surface grinding of cylinder and cone.

Coordinate grinder: it is an internal grinder with coordinate positioning device.

Centerless grinder: its main feature is that the workpiece is centerless clamping, and the support is between the guide wheel and bracket. Its purpose is to grind the cylindrical surface.

Surface grinder: as the name implies, it is a kind of grinding machine for grinding the workpiece plane.

Tool grinder: its main purpose is to grind tools.

Multi purpose grinder: this kind of grinder can grind various surfaces. Therefore, it can grind a variety of workpieces.

Special grinding machine: it is a kind of grinding machine specially for certain parts. It can have different types according to the processing object.

End grinder: its main purpose is to grind the end face of gear.

2. According to the motion characteristics and process requirements of the grinder, what are the general requirements for its electric drive and control?

On the whole, there are two main requirements, which are as follows:

Requirement 1: for the rotation of grinding wheel in grinding machine, there is no speed regulation requirement generally, and three-phase asynchronous motor is mainly used to drive. It is generally unidirectional.

Requirement 2: for the transmission, it is better to use hydraulic transmission, which can not only realize the reciprocating motion of the worktable, but also ensure the small inertia of the worktable when reversing, and there is no impact, so that the grinder can run stably and reliably.
