Factors to be considered in selecting surface machining methods for CNC machining

The processing method of the surface of the CNC machined part first depends on the technical requirements of the machined surface. However, it should be noted that these technical requirements are not necessarily the requirements specified in the part drawing. Sometimes, they may be higher than the requirements on the part drawing in some respects due to technological reasons. For example, due to the misalignment of the benchmarks, the processing requirements for the surface of some CNC workpieces are increased. Or, because it is used as a precision benchmark, it may put forward higher processing requirements.


When the technical requirements of the surface of each CNC machined part are clarified, the final processing method that can guarantee the requirements can be selected accordingly, and can determined processing methods of several working steps and each working step. The selected machining method of CNC parts should meet the requirements of parts quality, good machining economy, and high production efficiency. For this reason, the following factors should be considered when selecting a processing method:









5 points to pay attention to in surface treatment of parts


1. The machining accuracy and surface roughness obtained by any CNC method have a considerable range, but only in a narrow range is economical. The machining accuracy in this range is the economic machining accuracy. For this reason, the corresponding processing method that can obtain economic processing accuracy should be selected when selecting the processing method.


2. The properties of the CNC workpiece material should be considered.


3. The structural shape and size of the CNC workpiece should be considered.


4. Productivity and economic requirements are to be considered. High-efficiency advanced technology should be used in mass production. It is even possible to fundamentally change the manufacturing method of the blank, which can reduce the labor of machining.


5. The existing equipment and technical conditions of the CNCfactory or workshop should be considered. When choosing a processing method, the existing equipment should be fully utilized, tap the enterprise's potential, and workers' enthusiasm and creativity should be brought into play. However, it should also be considered to continuously improve the existing processing methods and equipment, adopt new technologies and improve the technological level.

Are Precision CNC Machining Services Suitable for Industry? A CNC-based precision machining system is a great choice for manufacturing today because the design of CNC precision machining is conducive to modern manufacturing. We live in an age in which there is "custom" production. In the China the past, the majority of the manufacturing process was driven by high-production and a lack of focus on modifying the final product. However, the majority of manufacturing today is focused on a greater degree of customization. The Tuofa Precision CNC machining manufacturer This design philosophy demands an extreme amount of flexibility. The Precision CNC Machining process is engineered to provide higher precision and repeatability and shorter setups, short lead times, shorter inventoriesand complicated fixing. This kind of CNC Machining Services is utilized to manufacture components that are used in almost every modern market. It's also a great fit for the application of

Technical requirements for precision machining parts

1. Precision Machining Shaft Parts 1) Dimensional accuracy, the journal is the main surface of shaft parts, which affects the rotation accuracy and the working state of the shaft. The diameter accuracy of the journal is usually IT6 ~ 9 according to its use requirements, and the precision journal can reach IT5. 2) Geometric accuracy, journal geometric accuracy (roundness, cylindricity), generally should be limited to the diameter tolerance point range. When the accuracy of a geometric shape is required to be higher, the allowable tolerance can be specified on the part drawing separately. 3) In The machining position, the accuracy mainly refers to the coaxiality of the matching journal of the assembly transmission parts relative to the supporting journal of the assembly bearing, which is expressed by the radial circular runout of the matching journal to the supporting journal; According to the use requirements, the high precision axis is 0.001 ~ 0.005mm , and the general preci
