Structure and types of double disc grinding machine in detail

A double disc grinder is a high-efficiency surface machining machine whose main function is to grind two parallel faces of a workpiece at the same time in a single machining process. There are various structures and types, which are described in detail below.

Structure of double disc grinding machine

The structure of a double disc grinder usually consists of the following key components:

Frame and base: provide support and stability to the overall structure, usually made of steel or other alloys to ensure the machine's stability at high speeds.

Power system: includes electric motors or hydraulics, which are used to provide power to rotate the grinding wheels or heads, and are a central part of the machine's operation.

Control system: Contains various sensors, control panels and programmes to control parameters such as speed, pressure and grinding depth during machining to ensure machining quality and accuracy. Modern double face grinding machines mostly adopt CNC system, which can realise the automation and intelligence of the machining process.

Cooling and lubrication system: For working conditions requiring high-speed grinding, the cooling and lubrication system can effectively reduce the heat in the grinding process and prevent the workpiece or grinding wheel from being damaged due to overheating.

Grinding wheels or grinding heads: components that directly grind the workpiece, the material, size and shape of which depend on the processing requirements. Double face grinding machines are usually equipped with two grinding wheels or grinding heads to achieve simultaneous grinding of both ends of the workpiece.

Feeding mechanism: Responsible for feeding the workpiece into the grinding area and adjusting the feeding speed and direction according to the processing requirements. According to the different feeding methods, double face grinding machines can be divided into various types such as feed-through type, turntable type and reciprocating type.

Types of double disc grinding machines

There are many types of double disc grinding machines, which can be classified into many types according to different criteria:

Classified by structure: they can be divided into horizontal and vertical types. Horizontal double disc grinding machines are suitable for processing large or heavy workpieces, while vertical double disc grinding machines are more suitable for processing small or precision workpieces.

Classification according to feeding method: as mentioned before, it can be divided into penetrating type, turntable type, reciprocating type and so on. Each feeding method has its unique processing advantages and scope of application.

Classification by function: it can be divided into ordinary double disc grinding machine and CNC double disc grinding machine. It realises the automation and intelligence of the machining process through the pre-programmed control system, which greatly improves the machining efficiency and precision.

In addition, the equipment can also be classified according to different processing objects, such as bearing double disc grinding machine specially used for bearing collar grinding, piston ring double disc grinding machine used for piston ring grinding, etc..

To sum up, the structure of double disc grinding machine is complex and precise, and its types are diverse and distinctive. When choosing and using the machine, it is necessary to make comprehensive consideration and selection according to specific processing needs and workpiece characteristics.
