A grinding machine is an industrial machine tool that uses an abrasive wheel for cutting. There are different types of grinding machine available, each with a different purpose.
A grinding is an industrial machine tool which is used to for finishing purpose.This process are secondary process and done after primary machining process.
Different Types of Grinding Machine:-
- Surface Grinding machine
- Cylindrical Grinding machine
- Internal Grinding machine
- Special types of grinding machines
Surface grinding machine:-
A surface grinding machine is used to machine the outer surface of product. This machine consist of an abrasive wheel, a chuck , and a rotary table.
Surface grinding machine are also classified according to the position of the spindle and working table which are as follows.
- Reciprocating table with horizontal spindle
- Reciprocating table with vertical spindle
- Rotary table with horizontal spindle
- Rotary table with vertical spindle
Cylindrical Grinding machine:-
A cylindrical grinder is used for shaping the outside of a workpiece. These machines accept workpieces in a variety of shapes as long as they can be rotated through a central axis. In a cylindrical grinder, both the workpiece and grinding wheel are simultaneously rotated. Outside diameter grinders, internal diameter grinders, and centerless grinders are all types of cylindrical grinders.
A cylindrical grinder is used for variety of shape like tapered, straight and stepped profiles as long as they can be rotated through a central axis.
This machine are also classified as follow:-
- Centreless cylindrical surface grinding machine
- Universal cylindrical surface grinding machine
- Plain centre type cylindrical grinding machines
Internal Grinding machine
This type of grinding machine is used to machine the internal surface of cylindrical product and using this machine we can capable to machine different shape like tapered, straight and stepped.
This machine also divided into following three types:-
- Chucking type internal grinding machine
- Centre less internal grinding machine
- Planetary internal grinding machine
Special types of grinding machines
There are some special types of grinding machine which are used for some special operation.
- Tool & Cutter grinders
A tool and cutter grinder are used for machining of cutting tools which are used for milling , turning, drilling etc operations. This tool make use of a cnc machine tool with up to axes and multiple grinding wheels.This tool are also used for making tool for woodworking and metal cutting industries.
- Creep feed grinding
Creep feed grinding is abrasive machining process. In the process High depth of cut and a high metal removal rate is introduce with relatively low table speed. Main reason for using this process is to complete all machining process in a single pass and to increase productivity.
- Thread Grinding Machine
This type of machine are used to produce very fine thread after completing grinding operation.This machine are same like a cylindrical machine but has very precised lead screw for producing the accurate pitch on the threaded part.
