These processes start with solid blocks, bars, or rods of metal, or plastic that are shaped by removing material through cutting, boring, drilling, and grinding. Unlike most other plastic manufacturing processes, CNC machining is a subtractive process where material is removed by either a spinning tool and fixed part (milling) or a spinning part with a fixed tool (lathe).

Gear grinding process is the method of finish grinding gear teeth and is a significant step when building high precision gearing.Gears with precision ground teeth work more softly and consume more evenly than gears with cut teeth. Gear grinding process is often done as a step in the gear manufacturing method, and we also give a gear grind only service.

Magnet Manufacturing Process. There are several processes for making magnets, but the most common method is called Powder Metallurgy. In this process, a suitable composition is pulverized into fine powder, compacted and heated to cause densification via "liquid phase sintering". Therefore, these magnets are most often called sintered magnets.

The grinding pressure is generally controlled at 0.5-0.8 kN (0.025 MPa), the grinding head speed is 60-80 r/min, and the grinding disc speed is about 60 r/min. The grinding disc needs to be sharpened during the grinding process to ensure the removal rate of the silicon carbide single crystal substrate.
