Recently, the 2023 Shanghai International Machine Tool Exhibition was held in Shanghai. The booth of Jun 'ang Precision Equipment Co., Ltd. from Dongcheng District, Dongguan, attracted many domestic and foreign exhibitors and visitors to stop by for viewing and negotiation. It is understood that the company's P-ONE (optical curve projection grinding machine),

The main shaft of the grinding head can perform lateral feed motion along the horizontal guide rail of the slide plate. The slide plate can also move vertically along the guide rail of the column to adjust the vertical position of the grinding head and complete the vertical feed motion. On the worktable of a surface grinding machine, electromagnetic chucks are usually installed to hold ferromagnetic parts. The electromagnetic chucks can also be removed and other fixtures can be installed, or the workpiece to be processed can be directly held on the worktable.

Optical curve grinding machines are used for grinding precise and complex surfaces, including straight lines, arcs and curves. During the grinding process, the workpiece and grinding wheel can be magnified 20 or 50 times through an optical system and projected onto a screen. During operation, the operator can observe at any time on the screen the processing situation of the grinding wheel along the workpiece surface. The movement of the workpiece being processed can be manually operated or automatically processed by the program to achieve the purpose of processing irregular shapes

The operator must be familiar with the performance, processing range and precision of the machine tool in accordance with the machine tool's user manual, and be proficient in the functions and operation methods of the machine tool, its numerical control device and each part of the computer.

Optical curve grinding machines can grind holes with very high hole pitch accuracy and various contour shapes. The processing is carried out in conjunction with a plotter. The plotter sketches the graphics to be processed onto the film, which is then attached to the projection screen and corrected. The processor will perform the forming processing based on the shapes on the film. Optical projection grinding is suitable for the forming grinding of high-hardness materials, such as tungsten steel parts or hard alloy workpieces, and occasionally some high-speed steel workpieces. Generally, it is used to process parts such as cutting edges and punches for connector dies, terminals, precision half-stroke punches, lower die inserts and discharge plate inserts, etc.

Before the advent of numerical control digital displays, this was a high-precision curve grinding machine, mostly imported. It reflects the shape of the curve through the refraction of light. It was generally used when processing curved surfaces with high precision requirements, grooves for high-precision parts, internal and external R, complex-shaped and high-dimensional tools, etc. In the past, it was an indispensable device
