CNC Grinders – Essential Service and Maintenance Tips
Centerless grinder is a unique machining method that utilizes abrasive driving to remove unwanted material from a working piece. This is a much simpler, and more efficient method of cutting holes in solid materials than traditional milling machines and screw machines, which require use of a table or an intermediate machine. It can be used on any work-piece that can be drilled or sanded, including metals, plastics, ceramics, composites, leather, and paper among others. It has many benefits, which include accuracy, minimal operator fatigue, speedy cutting speed, and economical operation. Also, it is fast becoming popular because of its ease of use and cost effectiveness.
Centerless grinders are designed to operate in an “automatic” fashion. The procedure typically begins by feeding the work part into the grinding machine’s deck and then feeding the grinding tool’s cutting head through the open holes. Once the work part is firmly seated, the grinding disk is spun by the motor in the machine to cut the material. The result is an extremely sharp edge on both the inside and the outside of the part. Since there is no need for a table or other work surface to support the work, part quality is often superior to that of a conventional machine.
With a centerless grinder, the work itself does not touch the table. This means that there is a reduction in heat produced during the grinding process and a correspondingly lower level of wear and tear on the workers. Because the work is not supported by a moving workers, the material cut is also free from burrs and slivers. Additionally, because the work moves through a fully enclosed workers, cuts are less likely to deflect off the workers and onto the table or other work surface.
In order to ensure optimum performance from the centerless grinder, it is important to keep it well oiled and greased. Some manufacturers suggest that oiling every thirty days is sufficient, while others suggest that it be greased every four or five days. Either way, the oil ensures that the bearings and other parts of the machine are properly lubricated, which prevents them from suffering from wear and tear. Over time, excessive heat can build up on the bearings, which will eventually affect their performance. Therefore, it is important that you keep your machine in good condition by performing regular centerless grinding machine maintenance.
One important point of centerless grinder maintenance is that you should always allow the machine to cool down after any abrasive material has been used to clean off the wheel heads. The reason for this is that overheating the wheel head can damage both the wheels and bearings, as well as the bearings themselves. If you don’t allow the cooling unit to cool down completely before starting the grinding process, you risk having the wheels pop out of the bearing heads. If this happens, the result could be incomplete grinding, which may lead to ineffective grinding and a lack of progress. Another cause of overheating is when the machine is being run without the motor running, which can often cause the bearings to overheat.
There are many types of machines available to the CNC grinders’ user. In addition to the two basic types of centerless grinders available, there are specialty types of machines such as the CNC lathe, which grinds the material into specific shapes. These machines generally have a slide-type control mechanism which is used to move the workpiece around the bed. This type of operation requires additional training to master, but the ability to operate these types of machines is essential to the professional who needs to produce quality work in a timely manner.
