Types of CNC Centerless Grinding Machines

CNC centerless grinding machines are typically used to economically cut and grind large metal workpieces, such as hydraulic pistons, into cylindrical shapes. Different kinds of centerless CNC grinders exist to cater to specific industry needs.

• Top Throne Centerless Grinders

  A top throne centerless CNC grinder has the grinding wheel positioned at the top side of the workpiece in a predominating horizontal orientation. It can be utilized to cut and grind wider or flatter metal objects. Additionally, top throne centerless grinders are typically used to complete lower precision tasks. Otherwise, more refined procedures could be employed.

• Bolt Centerless Grinders

  Bolt centerless grinding machines can be powered manually or automatically. Regardless of the method of power, the workpiece is loaded into the centerless grinder by employing a holding fixture known as a collet. A collet is used to grasp the smaller part of an object. After insertion, the machine can then be used to cut, slice, and grind irregular or cylindrical shapes. Like the top throne machines, bolt centerless grinders are typically used to achieve lower precision and tolerance levels.

• Through Feed Centerless Grinders

  Through feed centerless grinding machines work on parallel workpieces. Unlike other types of centerless grinders with supporting wheels and spindles, a through feed centerless grinder has the item in between the grinding wheel and the support wheel. This gnashing machine then works its way on an axis towards the spindle wheel and the exit. It can be used to manufacture cylindrical shafts at a lower cost. Through feed grinders are ideal for accomplishing high-production tasks and can achieve tighter tolerances and higher precision levels. However, through feed machine centers carry the risk of becoming jammed and thus require regular maintenance and care to work correctly and efficiently.

• In-Feed Centerless Grinders

  In-feed machines are preferable to use when working with odd-shaped objects or those with changing diameters. Generally, the object is fed into the center of the machine, where it will be cut and ground to a specific shape and size.

Specification and Maintenance

The specification of the CenterlessCNC grinding machine will differ depending on the kind and model a person buys. However, generally, the capacity of the grinding diameter ranges from a quarter of an inch to a half of an inch. The length capacity also ranges from 1 inch to 30 feet. The maximum power for the grindings machine is always above 10 HP. The work rest is usually about 15 degree and 12 inches long. The tilt of the machine can either be horizontal or vertical. The coolant pump capacity is usually more than 5 gallons per minute(All about CNC Centerless Grinder Machines).

A CNC centerless grinder machine works best if it is well taken care of. Therefore, it is essential to know the kind of maintenance an ideal centerless grinding machine requires. Generally, the machine needs to be cleaned regularly. The manufacturers of the grinding machine recommend routine lubrication as well. This helps to reduce wear and tear and enables the machine to function smoothly. Parts of the grinding machine that move regularly should be oiled often. While doing routine maintenance and cleaning, one should pay attention to the coolant system and do necessary repairs to avoid any leaks. For efficient machine operation, one should always ensure the belts and blade are tight. They should not have any excess wear or tear. Only experienced and qualified technicians should carry out the repairs.

How to choose CNC centerless grinding machines

The choice of CNC centerless grinders for sale will depend on the specific needs and requirements of the business purchasing it. Some of the factors to consider are the kind of material used in the construction of the machine, its operational capabilities, and its automation level.

Industrial-grade and high-performance CNC centerless grinding machines are usually made with cast iron structures. This gives the grinders a steady foundation and support, which reduces vibrations while cylindrical workpieces are being ground. Workpieces with wide diameters need strong machines to do the grinding properly and maintain tolerance levels.

Casting steel centerless grinding machines can handle high workloads and heavier workpieces. This is possible because steel is a more durable and stronger material than cast iron. Steel also absorbs impact better, leading to increased stability and accuracy while performing centerless grinding operations on workpieces.

An automatic centerless CNC grinding machine has a greater level of precision and repeatability. This is because automation reduces human error while increasing productivity. Automatic or semi-automatic centerless machines usually have larger through-feed capacities. For this reason, they are greater manufacturing industries with high production demands.

Generally, three main methods of feeding workpieces into a centerless grinding machine exist: in-feed, through-feed, and end-feed. The in-feeding technique involves grinding workpieces of different shapes and sizes. After being set and established, a centerless machine will receive the feeding workpiece vertically between the grinding wheel and regulating wheel. Usually, workpieces with complex geometries and shorter lengths are in-fed. This method of feeding workpieces is automatic, in that a hydraulic or CNC system brings workpieces into the machine for grinding. Regulating wheels move the ground workpieces out. This method of workpiece feeding requires a high level of skill and lower production capacity.

A machine that uses the through-feeding method is the most productive centerless grinder available. It is suitable for long, cylindrical workpieces. It has to be fed continuously. A major benefit when using this technique is the reduced cost per units ground because of the highproduction rates of workpieces. However, the workpiece must have consistent diameter throughout its length, making this workpiece feeding method unsuitable for irregularly shaped workpieces.
