What exactly is a surface grinder? A grinder is a rotating tool used for smoothing the surface of an item. Its name is derived from the wheel that the device uses to perform its function; it is referred to as ‘wheels’ because of this. The grinding wheel rotates at a very high speeds and is usually attached to the tool’s table via a chain or other rotary link. The wheel’s contact with the work surface is what makes the grinding occur, and the tool’s ability to obtain a homogenous result is due to the fact that it only comes in contact with one part of the surface. The grinding of a particular material occurs when the tool’s contact with the surface creates imperfections in the material’s surface, causing the formation of minute abrasive’scratches’.
A homogenous result can be obtained by turning the device on its axis, or ‘wise’ if you are referring to a machine which operates in a horizontal manner. Turning the machine results in the immediate opposite of a homogenous material, and the product thus produced is a rounded or flattened one. This is the result of the homogenous or rounded shape that is imprinted on the work material as a result of turning the device. This is the most basic definition of a surface grinder, but there are two main types:
The two types of surface grinders are those which use a stand mounted platform and those that sit on a table. The former is the most common type of machine used today and has the advantage of providing the user with a far more versatile operation surface, whilst also being very reliable. The downside is that it requires a source of power, and in the case of mobile machines, can become quite inconvenient to use. The second type of machine is more complex and heavier, as well as requiring a power source, but also offers greater precision. It is also far more reliable and allows users to produce far more exact results.
One of the main differences between the two is that the former needs a power source, whereas the latter does not. However, there are a number of advantages inherent in both types of equipment, and the end user is likely to be best placed to explain which is most appropriate for their requirements. In addition to being able to use both wheels at once to increase production, a surface grinder also offers a greater amount of accuracy, as well as being far more durable than a grinding wheel machine.
The most common types of power sources used in surface grinder machines include electrical and hydraulic. There are two main types of electric motors, which are often found in these machines: those which are directly mounted onto the chuck wheels themselves, and those which are mounted onto an electrical jack stand. Hydraulic machines are generally less expensive to run, and they also tend to have a higher level of reliability and longevity. However, it is often found that using hydraulic surfaces requires a lot more maintenance than those which use electrical power. A magnetic chuck, on the other hand, is far more reliable and much less expensive to run, although it also requires a high degree of maintenance to keep it in top condition.
Many people prefer to use surface grinding machines in conjunction with a magnetic chuck, mainly due to the increased accuracy that they offer. In order to work with surface grinders and magnetic cutters effectively, it is important to understand how each type of equipment works, and what their differences are. With surface grinders, work pieces need to be turned into their crosswise (turning) position in order to get the grinding action started. Once this has been achieved, the work piece can then be turned perpendicular to the grinder, and the grinding action will commence. With a magnetic chuck, this is easier to achieve, as the work piece will already be turned perpendicular to the grinder – the only thing required is that it be held in this position for a sufficient amount of time to allow the grinding action to take place.
