In mechanical processing, for parts with high geometric accuracy and high surface quality requirements, especially when the materials are hardened steel, cemented carbide, ceramics, silicon, germanium, quartz glass and other hard and brittle materials, a complete milling process and grinding is required. process to achieve the required treatment effect.The shape contour processing is completed by the milling process. In order to further meet the size and shape requirements of workpieces and ensure the surface effect of the workpiece, the grinding process is used to achieve high precision and high surface quality processing.
✦ Composite processing solution for milling and grinding ✦
In order to improve the processing efficiency of these parts, a composite milling-grinding processing method has appeared in the industry. By performing milling and grinding in a single device, processes are merged and process flow is reduced.
Beijing Jingdiao relies on Jingdiao high-speed grinding center to apply milling and grinding composite processing solutions to many industries. Let’s take a look at the application of Beijing composites precision engraving, milling and grinding solutions.

Jingdiao’s on-machine inspection system can perform tool and workpiece measurement during milling and grinding processes.
Control of tools on machine
During milling processing, the tool length, tool radius, tool profile and other parameters are tested on the machine to ensure that the precise tool size is used for the treatment.
On-machine inspection of grinding wheels
For grinding wheels used in grinding processing, the diameter of the grinding wheel is accurately detected by the professional grinding wheel tool adjuster produced by Jingdiao to ensure that the precise diameter of the grinding wheel is used for grinding.
Inspection of parts on machine
The machine automatically performs incoming material inspection, process inspection and finished product inspection of parts to ensure that the parts are qualified as soon as they come out of the machine.
03Configuration of key components and accessories
Considering the characteristics of the grinding process in milling and grinding composite processing, it is equipped with key components and accessories developed by Jingdiao to accurately execute micron-level processing technology.
Jingdiao high speed precision electric spindle
In order to reduce the impact of the large amount of heat generated during grinding on the precision of workpieces, Jingdiao’s high-speed precision central water electric spindle is used to completely cool the grinding tools and workpieces so as to to guarantee grinding at micron level.
Jingdiao JD50 CNC system
Equipped with Jingdiao JD50 CNC system, it supports the use of different grinding tools for grinding processing.
For grinding spherical/aspherical parts, a parametric grinding programming module is also provided to improve the smoothness of grinding motion by eliminating nodes from the processing path.
Jingdiao high-speed direct drive turntable
In order to ensure the precision of workpiece grinding, a high-precision direct-drive turntable is configured to realize high-precision five-axis linkage and five-axis positioning grinding.
