Non-standard Knives Are Customized, First Need To Pay Attention
In the process of machining, some difficulties in which it is difficult to use standard tools, and therefore, the production of non-standard cutters is important to mechanical cutting. Because metal cutting uses non-standard cutters more common in milling, the production of non-standard cutters in milling processing is slightly introduced.
Since the fabrication of standard tools is for the cutting of a wide range of common metal parts or non-metal parts, it is very easy to stick to the hardness of the workpiece, or the workpiece is stainless steel, etc., and some workpiece surface geometry The shape is very complicated, or the surface has a high roughness requirement, etc., the standard tool cannot meet the needs of processing. Titanium machinery is a main product of rotation, screw, axial machining, CNC lathe processing, knife holder rod, and chuck pick-up, so during processing, the geometry of the tool, the geometry of the knife, geometry Angle, etc., for targeted design, can be divided into two major classes that do not need to be specifically customized and needed. It is mainly to solve two problems, such as dimensional problems and surface roughness problems.
If it is a size problem, you can choose a standard tool similar to the size of the desired size, can be solved by reforming, but also pay attention to two points:
() The size is not too large, generally do not exceed 2mm, because the dimension is too large, causing a change in the groove shape of the tool to directly affect the cost of costumes and geometries.
(2) If it is a vertical mill with a blade, it can be changed on a normal machine, the cost is low. If it is a keyway milling cutter without a blade, it cannot be carried out on ordinary machines, and it is necessary to be in a special five-axis. The linkage of the linkage machine is higher.
If it is a surface roughness problem, it can be realized by a change in the geometric angle of the blade portion. If the maximum number of the rear angle will significantly improve the surface roughness of the workpiece. However, if the machine is not enough, it may be sharply improved surface roughness, which is very complicated in this regard, and it is necessary to conclude after processing site analysis.
