Generally, the forming die is used to grind the convex mold, that is, the grinding wheel is trimmed into an inverse surface that matches the profile of the workpiece, and then the workpiece is ground with the grinding wheel to obtain the desired shape. There are many methods for trimming the grinding wheel. The following:
When a diamond is used to dress a grinding wheel, it is generally necessary to trim the geometry of the forming surface in sections, and it is also necessary to use a grinding wheel to trim the shape. This method of dressing the grinding wheel is generally completed by various grinding wheel tools. The tools for repairing grinding wheels in production generally include tools for repairing angles and arc wheels.
When grinding the workpiece, it can be clamped on a special fixture. During the machining morning, the grinding is performed at a fixed or constant position to obtain the desired shape. This grinding method is generally performed on a surface grinder.
In production, in order to ensure the quality and efficiency of grinding, the comprehensive use of forming wheels and fixtures is generally used, which can greatly reduce the manufacturing cost of parts.
When forming and grinding, the operator needs to directly convert the design size of the pattern into the size of the forming and grinding process. Due to the different processing methods of individual parts, there are different requirements for the conversion of the size and forming process.
