Milling parts
on cnc machines
CNC turning is a modern way of metal processing, which allows you to produce a variety of hardware with high accuracy and in full compliance with the standards, as well as customer drawings.
CNC means numerical program control, which means that computerized systems take over the control of equipment. The input signal is a digital code. This controls all tool movements and rotational speeds, as well as other auxiliary actions such as coolant usage.
Peculiarities of work on CNC machines
As you know, equipment ensures the accuracy of the workpiece. The advantage of CNC machines over universal machines is that the tooling on them is more accurate.
CNC milling is used in mass production of parts, because with the help of software the repeatability in the manufacture of products is ensured. With universal equipment, repeatability is ensured by the skill of the milling engineer, in which case the quality of a high-precision product can have a significant impact on the “human factor”. Therefore, it is better to turn to CNC for manufacturing a series of products, where the quality pays off the high cost.
“METMAX” engaged in high-precision production, for which universal equipment is not suitable, so we use CNC machines in our work.
Manufacturing Characteristics
The cost of milling work is determined by the number of man-hours required to produce a part. On CNC machines, the normative hour is more expensive because more complex and more precise tools and technologies are used and it is necessary to write a control program.
The accuracy of manufacturing depends on the tools, the positioning accuracy of the equipment, the rigidity of the machines, and the skill of the technologists who fully develop the process and assign the cutting modes.
Our company is engaged in one-off production, where each project requires an individual approach: the technologist selects the tools, cutting modes, equipment and writes the control program.
We also do anodize – applying a protective coating after milling, which provides corrosion and wears resistance characteristics of the surface and gives it the necessary color by adding a dye.
