Variable speed controllers
The control panel of an end face cylindrical grinding machine is comprised of a series of axes, each with its own motor. The axis of the machine is driven by a variable speed controller that provides the necessary power to the grinding wheels. The axes are connected by a shaft and rotate in a clockwise direction. The grinding wheel is contacted by the grinding wheel's edges by the feed pawl I38, which rotates in a clockwise direction.
A swivel table may be fitted to the swivel table for ease of adjustment. In addition to being offset, the swivel table may also be fitted to the sliding table. The right hand end of the swivel table features a handwheel. The hand control is used to select the desired spindle speeds. There is a wheelhead assembly containing both external and internal grinding spindles. Separate motors are installed on the wheelhead. The swivel table may also feature feed stepping at the end of each table stroke.
Targeting the entire grinding zone
The proper selection of a cylindrical grinding wheel can significantly improve the end results. Grinding wheel selection is dependent on workpiece characteristics, including geometric accuracy and surface integrity, and economic objectives. When choosing a cylindrical grinder, it is essential to understand how each one functions and how it can help meet your needs. This article discusses some of the factors to consider when choosing a grinder. Listed below are the benefits and disadvantages of each type of grinding wheel.
The grinding wheel's infeed rate refers to the extent of penetration of the wheel into the workpiece. The further the wheel advances, the greater the reduction in the workpiece's diameter. Some cylindrical grinding machines feature a cross-slide handwheel with graduations to express expected workpiece diameter reduction. Depending on the application, an infeed rate of two times the wheel advance may be desirable.
Choosing a grinding wheel
When choosing a wheel for an end face cylindrical grinder, consider the workpiece surface quality. A compact grinding wheel produces a smoother surface than a loosely organized one. The gap between the wheel and workpiece should be large enough to prevent blockage. A large gap is also desirable when grinding soft metal. While a compact wheel is better for rough grinding, it can be easily blocked for soft metal.
Choose the right speed for the job at hand. The speed of the grinding operation will determine the finished quality of the ground surface. The speed will also be affected by the type of grinding fluid and the skill of the operator. The frequency of wheel dressing and the type of coolant will also affect the final surface finish. In addition, the type of wheel will determine the speed of the machine. The desired quality level and cost will also determine the choice of wheel.
