The workpiece installation identification is designed according to the characteristics of the workpiece, and is placed in the axial and radial positioning of the auxiliary bracket, and controlled by photoelectric or non-contact signals to prevent errors during human installation.

The axial positioning of the workpiece uses a shoulder surface of the workpiece as an axial positioning reference. Through the axial axis feeding of the workpiece, the positioning gauge is contacted with the workpiece positioning shoulder surface to obtain the base point of the NC coordinate axis programming. For some workpieces, the axial position is completed at the time of installation with its own shoulder surface, and the positioning gauge can be omitted to simplify the grinding process. However, the accuracy of positioning the shoulder surface of the pre-process should be improved accordingly.
Automatic measurement of workpieces For micron-level grinding accuracy, an on-line automatic measuring device for workpieces is generally required. Most of the automatic measurement is installed on the table, and by program control, the workpiece is measured, and the rough, fine, and size signals are sent out and the workpiece is exited.
Most of the grinding and cooling of the workpiece uses high pressure, large flow, magnetic, paper filtration, and even a cooling system with a refrigeration unit.
The grinding wheel of the grinding wheel relative to the workpiece is different from the tool for turning, milling and drilling. It is extremely easy to wear and the dimensions are constantly changing. As the size of the grinding wheel becomes smaller, the position of the grinding wheel frame moves forward. When designing, consider the extreme position of the movement of the grinding wheel frame, the spatial position that may interfere, and the position where the grinding wheel may be trimmed. For some machine tools that can cut the end face and the outer circle, the grinding wheel is inclined at an angle of 30° with respect to the workpiece. The amount of movement in the feed direction of the wheel frame has a function relationship with the amount of movement in the vertical direction. Therefore, the numerical control system is required to have a skew axis function.
The setting wheel dressing wheel dressing device is mostly set on the work surface or the head frame to fully utilize the movement of the two feed CNC axes to realize the shaping and dressing of the outer circle of the grinding wheel. This greatly simplifies the machine structure. At present, the appearance of the thin diamond wheel dressing device can greatly improve the dressing precision of the grinding wheel.

Table layout design example
The layout design of the countertop is to design the above-mentioned various configurations with existing modules, functional components and a small number of process components by means of the workpiece as the core, see the right figure. Due to the large number of countertop placement devices, it is necessary to design the installation, movement range, space, human interference and the configuration of the process components one by one accurately until the grinding program of the machine tool can be edited. the Lord.
