SKF bearing ring face double disc grinding a face grinder with two grinding wheel at the same time across the grinding workpiece surface processing methods.
Double disc grinding step of grinding two end faces merged into one step, the step of reducing the number of reduced motor time and auxiliary time. Automatic measurement, automatic loading and unloading not only improve productivity, but also reduce the labor intensity. From the grinding accuracy, another advantage is easier to obtain a high machining accuracy. Single head vertical shaft surface grinding machine grinding, the workpiece needs twice positioning, two processing positioning error, wheel position error with respect to the magnetic station magnetic Taiwan inequalities are reflected to the ferrule end face. Double face grinding, machining surface is the positioning surface and the two end faces a pulverized, which avoid the superposition of positioning errors and machining errors, while not exist magnetic station uneven and magnetic force caused by lack of deformation of the workpiece caused by processing errors. Practice has proven that in processing small and medium-sized ferrule, the ferrule width fluctuation amount comparable the kingpin plane grinding accuracy significantly improved accuracy. In addition, the double disc grinding pipelined continuous grinding ferrule, easy to automate, and linked into automatic production line. Grinding without magnetic chuck, it should be the government thinned shaped workpiece, eliminating the need for auxiliary work such as demagnetization, reduce labor intensity.
Double face grinding of many types, according to the movement of the work can be divided into the following five categories:
A straight line through the ceremony.
The straight line through the-works is a highly efficient and easy to automate best grinding its scope mainly simple ring workpiece shape, such as SKF bearing rings, gaskets, piston rings.
2 TDs. Circle solitary.
Arc throughout the works is a highly efficient and easy to automate the grinding way this way is mainly applied to the irregular shape of the workpiece, such as small SKF bearing rings, micro rings, roller.
