The latest high-tech kind of grinding machinery available today are the computerized CNC grinding machines. CNC stands for “Computer Numerated Control.” This allows complete automatic part machining to be done almost completely automatically. Even with the thinnest of piece geometries, like camshafts, crankshaft assemblies, bearings, or transmission lines, it is now common to achieve fast, accurate and efficient machining using CNC machines.
CNC grinders can move in several axes. In CNC grinding, the workpiece can be moved in the X, Y or even Z axis. The workpiece can be moved without moving the grinding wheel. Grinding wheels are attached to CNC grinders by a guide rod. The amount of guide rod that is attached to the CNC grinding machine can be controlled through a potentiometer attached to the computer.
A variety of CNC grinding machine drives are available to allow the user to program different functions into them. One of these is the computer driven SDCC, or self-contained drive control. This type of drive allows the computer to specify the parameters that need to be set for the grinding process to occur. It also controls the amount of CNC grinder motor’s drive torque, temperature and other system factors necessary for the proper performance of the CNC grinding process.
High-quality output from CNC grinders can be achieved when the proper water cooling systems, and pressure are provided to the workpieces during the grinding process. Water cooling systems must include two separate stages, a stage designed to cool the workpiece to its melting point, and a stage in which compressed air is pumped into the workpiece to force cool air into the workpiece. Once the water has reached its melting point, the workpiece is ready to be ground. Some types of CNC grinders require only one stage of water cooling, while others incorporate both stages into their performance and output capabilities. CNC grinders also have variable-pressure options that can be adjusted according to the type and size of the workpiece.
There are other types of CNC grinding machine parts that are used to enhance the performance of the grinding process as well. These include high-quality wheels for fine-tuning the turning process and providing a smooth finishing process. High-quality CNC wheels have finer teeth than regular ones, which allows them to perform at a higher level of precision than regular wheels. Many CNC grinding machine users choose to add these wheels to their machines rather than purchasing them separately. The addition of wheels allows a higher level of precision and a smoother finish.
When operating a CNC grinding machine, it should be kept in top condition by using appropriate coolant lubricant supplies and keeping the machine tools as clean as possible. Using inappropriate coolant lubricant will lead to machine tools wearing out more quickly and with a much lower life span than they could if they were using proper coolant lubricant. The best type of lubricant to use for a CNC grinding machine is engine oil, because it contains synthetic lubrication oils capable of restraining and neutralizing the build-up of harmful materials in the bearing.
