How CNC Grinding Machines Work
Since the inception of electronic computer controlled machining (ECC) technology, new possibilities have been pursued for taking advantage of this unique, complex and energy-efficient machining method over ever shorter timescales at a consistent high degree of accuracy. Today’s most high-quality CNC electric motor driven grinders are the modern ultramodern CNC grinders. By virtue of their state-of-the-art computer numerical controlled (CNC) programming language, they can perform more complex tasks than their older predecessors. The latest CNC grinders are not only used for abrasive industrial grinding, but also for drilling, reaming, tapping, routing, honing and cleaning as well.
A CNC Grinding Machine is programming to duplicate a precisely controlled cutting operation by accurately positioning the cutting tool in the workplace. This enables the workpiece to be held stationary while the grinding wheels of the CNC machine operate on the workpiece, consistently and repeatedly carving away at the workpiece with virtually no human intervention. In short, the CNC grinding machine provides the basis for a truly robotic production line. In addition, it reduces the amount of man-made errors and waste materials while simultaneously increasing productivity. The result is an increase in profit and/or savings on the part of the business, enabling it to invest that money back into the company.
The CNC Grinding Machine is available in two basic varieties; those powered by electrical motors or those controlled by pneumatic pressure. All CNC grinders employ the same basic technology which is the result of high-speed computer numerical control (CNC) programming. In both cases, the CNC machines use variable range or speed commands to rotate and grind at various speeds and in different directions. However, the type of motor used will vary according to the intended application and the machinery’s capability to execute multiple programs at the same time.
Although many people mistakenly believe that the CNC grinding machine is suitable only for large industrial production cutters such as furniture pieces and other automotive parts, this is far from the truth. Because the CNC machine is designed to operate at higher speeds and with greater precision than traditional part machining methods, it is often used to manufacture smaller products such as pipes, pipe fittings, car parts, nuts and bolts, among others. Because the CNC system eliminates the majority of manual labor as well as human errors, the CNC machine can be utilized to manufacture an incredibly wide range of products. Some examples of the types of small-scale products produced using the CNC machine technology are: small metal parts such as nuts and bolts; precision bearings; and, in conjunction with a CNC machine, CNC jewelry and computer parts manufacturing processes.
One of the most common uses of the CNC grinding machine is in computer numerical control (CNC) machining operations. Typically, these types of CNC milling machines use a computer program to guide the workpiece along its progress. A computer program will specify precisely how long and in what direction the workpiece should move in order to make the necessary adjustments. The CNC grinding machine allows for the accurate and timely manipulation of workpieces in any environment. Typically, a CNC grinding machine can be programmed to make a one-millimeter-thick piece free from burrs, which are tiny imperfections that occur in CNC machining operations. In addition to producing free of burrs, this enables a computer numerical control (CNC) machine to work in a precise and repetitive manner.
The final component that a CNC grinding machine consists of is a mandrel. This is the piece that holds the workpiece stationary while the CNC grinder operates in its mode. Grinding machines will have a variety of different mandrel configurations, which are used to vary the angle at which the piece is ground. If the CNC grinder has a variable angle system, the operator will enter that number as a command into the computer. The command will specify the maximum grinding diameter that the grinder will hold; if the grinder has a manual holding power, then this command can also be entered into the computer.
