Machining Manufacturers Have Always Emphasized That The Products They Produce Must Meet The Precision Level, Which Means That The Actual Geometric Parameters Of The Steel Parts After Machining Are Consistent With The Idealized Values Required By The Part Drawings. The Level That Cannot Be Achieved In The Middle Is Called Production Processing Deviation.
The Precision Of Products Produced By Machining Manufacturers Mainly Includes Three Aspects. On The One Hand, It Is The Dimensional Precision, Which Limits The Dimensional Deviation Between The Standard The Processing Surface Layer Within The Required Range. In Addition, The Geometric Shape Precision Limits The Macro-Geometric Shape Deviation Of The Processing Surface, Such As Roundness, Taper, Cylindricity, Parallelism, Concentricity, Straightness, Etc.
Another Aspect Is The Precision Of Relative Positions, Which Limits The Relative Position Deviation Between The Standards Of The Machining Surfaces Produced By The Machining Manufacturer Such As Coaxiality, Flatness Parallelism. The Machining Accuracy Is The Reasonable Level Of The Actual Specifications, Styles, Geometric Parameters Of The Component Surface After Machining The Idealized Geometric Parameters Specified In The Engineering Drawings; Huiwen Zhizao Is A Machining Factory With More Than Ten Years Of CNC Machining Experience , With Complete Equipment, CNC Turning/Milling/Grinding/Drilling/Machining.

理想化的几何图形主要参数对于规格来说,说的是均值规格,对表层几何图形样子来说,是说的圆、平面图、圆柱体、球面以及平行线等,对表层中间的相互部位来说,说的是平行面、同轴输出、竖直、对称性等;
机械加工厂家所生产出来的零件实际上几何图形主要参数跟理想化几何图形主要参数的便宜标值称之为生产加工偏差,生产加工精度跟生产加工偏差全是评价生产加工表层几何图形主要参数的专业术语,生产加工精度用公差等级考量,等级值越小、其精度就越高,生产加工偏差用标值表达,标值越大,其偏差也就越大;
