Before the advent of numerical control digital display, the optical curve grinding machine was a high-precision curve grinding machine, and most of them were 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 cutting tools, etc. In the past, it was an indispensable device.

Grinding machines can process materials with high hardness, such as hardened steel, hard alloys, etc. It can also process brittle materials, such as glass and granite. Grinding machines can perform high-precision grinding with very low surface roughness, as well as high-efficiency grinding, such as heavy-duty grinding.

Grinding machines are precision equipment for performing fine processing on the surfaces of parts, especially hardened workpieces. The grinding machines mainly used in mold processing are surface grinding machines, universal internal and external cylindrical grinding machines, and coordinate grinding machines (PG optical curve grinding machines).

The grinding wheel is an indispensable tool in grinding processing. Whether the grinding wheel is selected properly or not is an important condition affecting the grinding quality and grinding cost. Our company produces a series of curve grinding machines, which need to be equipped with different grinding wheels to adapt to the curve processing of various workpieces. To facilitate users' targeted selection of grinding wheels, this article summarizes the selection of grinding wheels for curve grinding machines and the common choices of grinding wheels for different workpiece materials, for your reference.

A grinding machine is mainly used to rotate a grinding wheel to grind workpieces to achieve the required flatness. According to the shape of the worktable, it can be divided into two types: rectangular worktable and circular worktable. The main parameters of a rectangular worktable curved grinding machine are the width and length of the worktable, while the main parameters of a circular worktable curved grinding machine are the diameter of the worktable surface. According to the different types of shafts, they can be classified into horizontal shaft and vertical shaft grinding machines. Such as the M7432 vertical shaft circular table curve grinding machine and the M7130 horizontal shaft rectangular table curve grinding machine.

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 the grinding wheel can be magnified 50 times through the optical system and projected onto a screen. During operation, the operator can observe the grinding wheel's processing along the workpiece's profile at any time on the screen. The movement of the workpiece being processed can be operated manually or controlled by a DC motor to achieve the purpose of processing the profile.
