Talking about the precision parts, most of us may think about the cylindrical precision parts. As they have a centre of a circle, and are comparatively easy to process. Of course. except for some of the cylindrical parts with high precision requirement < 1um.
There are also some kinds of irregular precision parts with special shapes. These parts are non-cylindrical in shape, they are special shapes, but more closely resemble a straight rectangular or square shape. We call them custom precision parts or non-standard parts, or special parts.
These rectangular or square-shaped precision parts we mentioned are with high-precision request to +/- 1um or 2um. Not the common metal parts with low precision requirements.
These custom-made rectangular precision parts have wide applications. Some special parts are used in tungsten carbide material as the carbide cutting punches in the stamping Tools and Press Dies in the electronics industry, especially in the connector and terminals industry. These parts can be carbide punches and die inserts, die plates, etc.
Some other custom-made rectangular precision parts are used as the precision mold parts for the automotive, medical, and semiconductor industry, or mechanical parts in the automation systems. They are roughly rectangular or square in shape, but irregular. These are parts that sometimes need to use the hard metal tungsten carbide, or high-speed stainless steel material. So they are difficult to cut and process, and also have a high-precision requirement within +/- 1um or 2um.
Ordinary CNC machines can not process these kinds of specially shaped precision parts. A Profile Grinder is a must-have equipment, and needs experienced and skillful operators. There is also a need for some matched machining machines, like Wire-EDM, Surface Grinding Machines, and NC Lathe Turning Machines etc.
So it’s all about the Rectangular or Square shape Custom Precision Special Parts Machining. Langdi Precision is one of the expert company that specializes in this category, and serve many top Japan and Germany Customers.
