Abrasive Wheel Machines
Abrasive wheel machines, more commonly referred to as grinding machines, are used for a variety of industrial process grinding applications. The variety of processes utilizing abrasive wheel machines range from steel fabrication, metal fabrication, and shaving down materials to a specific size or shape.
Grinding machines have been around since the early 1800s and were one of the first machines to utilize electric motors in the early 1900s. Proper use of grinding machines is vital to achieving the desired process results. Knowledge and understanding of the components and their functions are important to successful grinding.
One of the key components in grinding machines is the abrasive wheel. The abrasive wheel is a special type of wheel composed of a grinding surface called a face and a roughened or patterned surface, typically referred to a wheel. Abrasive wheels are designed to hold a certain amount of abrasive grains and depending on the application, an optimal combination of grain size, grit, and grade are chosen when constructing the wheel. To keep the wheel durable and to maintain the proper grinding performance, the chosen abrasive mixes should be applied using the correct pressure and quantity.
The abrasive wheel is mounted onto a spindle and the spindle is driven by either a conventional motor, pneumatic motor, or electric motor. The spindle speed can be set to a constant speed or variable speed and that controls the rate at which abrasive grains come in contact with the material being processed. The cylinder and table can also be adjustable to position the material against the face of the wheel.
The grinding process must be monitored and regulated to ensure the desired result is achieved. Too much pressure on the material will cause excessive material removal and can damage the abrasive wheel. The grinding wheel should be chosen carefully, with accuracy in mind. The wheel must be the best size, grain type, and grade for each application. Casing guard and use of protective face shields are necessary for operator safety.
Grinding machines require a knowledgeable operator to introduce them to their full potential. Knowledge of proper grinding techniques, safety regulations, and operating procedures is also essential for successful grinding operations. By understanding and following these proper grinding techniques, you can ensure the safety of yourself and your employees as well as efficient and quality results. With the right knowledge, expertise and understanding of abrasive wheel machines, a multitude of process tasks can be achieved.
