If you’re looking to shape the exterior of an object, the cylindrical grinder is your ideal machine. It is one of the grinding machines used to form the exterior side of the workpiece by removing material from the surface of a workpiece. This grinding machine uses the central axis of rotation to grind the workpieces. It can process various shapes as long as they can be rotated through a central axis, not just cylinders. The cylinder rests between two centers and rotates in one direction, while the grinding wheel approach and rotate in the opposite direction.
In a Cylindrical Grinder Machine, both the workpiece and grinding wheel are simultaneously rotated. It is particularly useful for manufacturing parts that require extreme design accuracy for use. After all, a mechanical system in which each part has the right dimensions works optimally. The risk of breakage a deformation of parts is also reduced.
How does it work?
A cylindrical grinder consists of four parts: the head and tailstocks, the grinding wheel, the wheel head, and the table. The workpiece is held between the headstock and tailstock. The workpiece is rotated rapidly between the centers. The grinding wheel, which performs the actual grinding by spinning at a different speed from the workpiece in the opposite direction, is connected to the wheel head, which drives the grinder in various patterns such as plunge or traversing movements. At the same time, the table also moves laterally. It can work with a variety of materials to modify fragile parts while keeping them from vibrating and breaking. The part to be ground is put between two points that will make it rotate on itself. The wheel or millstone, an abrasive disc suited to the material to be handled, often rotates at a very high speed. The part will then move back and forth on the machine, removing imperfections with the aid of the grinding wheel.
Types of Cylindrical grinding machines
- Inside diameter machine: These machines make use of a collet for grinding the inside of the substance. This type of cylindrical grinding machine uses a wheel that is smaller than the substance’s width.
- Outside diameter machine: These machines use centers i.e. end units for grinding the external surface of the substance. The centers are used for rotating the object when it passes through the grinding wheel.
- Plunge grinding machine: The wheel is plunged into the work at a predetermined feed rate and is withdrawn after the correct size is produced. The grinding wheel moves radially toward the substance. It is also known as an infeed grinding machine.
- Creep feed grinding machine: This type of machine removes high volumes of material, producing deeper cuts, in a single pass of the grinding wheel and the table speeds are kept very low and the wheel is fed down to the full depth of cut in one or two passes. It is most widely used because its effective execution can minimize output time by half.
- Centreless grinding machine: Here the workpiece is not supported between centers but is held against the face of the grinding wheel by a combination of supporting rest and a regulating wheel. Thus centreless grinding does not require center holes, drivers, and other fixtures for holding the workpiece. This is typically used in applications where automatic loading procedures need to be used.
