CNC Precision Surface Grinder
Surface grinder is used to create a very smooth and flat finish on curved surfaces. It’s an extensively used rough abrasive machining procedure in which a rotating crescent-shaped drum having soft, rough metallic material cut various chips of non-metallic or metal material from a workpiece, producing a flat face of it smooth or flat. Grinding wheel usually has a steel sleeve with abrasive material at its center, and the workpiece is rotated by the grinding wheel. The high-speed rotating action of the grinding wheel tends to wear away the rough surface of the abrasive material, leaving a fine grit finish. This in turn is used for various applications including jewelry making and metal working.
In the past, metal working only required simple hand tools like chisels and avils; today there are numerous sophisticated machines that are used in abrasive cutting. Grinding wheel is the most important tool in the surface grinder; the quality of the finished product depends on how accurately the grinding wheel is set. For this reason, it is used along with other precision machined parts, such as drill presses and lathes. Grinding wheels are typically made of cast iron and are subject to wear and tear during use.
It can be said that the surface grinder is a specialized type of machining tool. It is more similar to a lathe than a drill press; both these devices are used for similar purposes but have different ways of doing them. Lathes, on the other hand, are generally used for cutting materials straight or at an angle. On the other hand, the surface grinding tools are used for cutting surfaces at an angle. In both cases, the device uses a rotating cutting tool to accomplish the task.
The most significant advantage of the surface grinder is its accuracy in cutting small areas. To accomplish fine work, a CNC (Computer Numerated Control) milling machine is used. With a CNC milling machine, the workpiece can be precisely moved into position while the cutting wheel is making direct contact with the work surface. This close contact gives a maximum possible accuracy in machining. The speed of the wheel allows the workpiece to be moved in a repetitive manner without worry of over-speed or excessive backlash.
The CNC surface grinder machine operates with the help of a computer program. This computer program helps the machine to identify areas of the workpiece that need fine adjustment. The computer also tells the machine where the workpiece should be positioned on the worktop. In this way, the machine positions the wheel in such a manner that the work piece remains totally inside the tolerance limits.
A CNC milling machine is programmed to operate at various speeds, which correspond to different increments in the size of the workpiece. This enables the machine to precisely position the abrasive wheel at the precise point and perform the finishing process perfectly. A CNC milling machine is an ideal solution for finishing all kinds of surfaces, including metals, wood, ceramics, plastics and others. This is because the machine operates with the help of a computer, which enables it to accurately control and program the operation of the finishing process.
