What are the Precision Parts Processing Methods?Langdi Precision2021-05-01T01:46:51+00:00
There are Various Kinds of Precision Processing Methods, Including (PG) Optical Curve Grinding, Precision WEDM Processing, Precision Surface Grinding, CNC High Speed Machining and NC Lathe Machining. Usually, A precision part or component is machined and processed by not only one processing method, it may contain several processing methods together to reach customer’s high precision needs.
What are the Precision Components Classifications?Langdi Precision2021-05-01T02:06:09+00:00
Precision Components can be classified with Hardware precision components, plastic precision components and automatic machine fixtures components. According to shape classifications, it can be classified as square components, round components and out-of-round components. According to standard classifications, it also can be divided into standard components and non-stand components. Usually, non-standard components require extremely high precision requirements.
PG optical curve grinding is a kind of precision components processing method and technology. It is used to grind ultra-high precision parts with complex profiles, including straight lines, arc and curve surfaces, high precision grooves, inside and outside radius. It is suitable for curve grinding special-shaped non-standard mold parts with high hardness. The precision can reach +/- 0.001mm and the surface roughness is Ra0.270.
