In the actual CNC machining process, it will be found that the same CNC lathe different personnel operation, in the same time efficiency varies greatly, many CNC lathe ability is not fully reflected, can not play its optimal role.In the use of the process, only fully consider the factors affecting the CNC lathe, CNC lathe ability to get full play:
1. Developed CNC processing technology
Usually a component can have different kinds of technological process, the different parts of the process, the production efficiency, processing costs and processing accuracy often have significant difference, so we should be on the premise of guarantee the quality of parts processing, according to the specific conditions of production, to improve production efficiency and reduce production cost, work out reasonable CNC processing technology.
2, choose the right tool
Selection of tools should consider CNC machining center processing capacity, process content, workpiece materials and other factors.High speed machining center by the choice of the tool, not only requires high hardness, high wear resistance, enough strength and toughness, high heat resistance and good technology, and requirements for size stability, easy installation and adjustment.Therefore, new high-quality materials should be used to manufacture CNC machining tools, and optimize the tool parameters, so that the size of the tool and the surface of the workpiece processed size and shape.So, how to choose the right CNC cutting tool?
3. Reasonably determine the tool setting point
Tool setting point is the starting point of the movement of the tool relative to the workpiece when the parts are processed on the CNC machining center.Also called “program starting point” or “play point”.The selection of knife points must follow the following principles: facilitate digital processing and simplify programming;Easy to find the correct on the machine, easy to check the processing;The machining error caused is small.The position of the tool point can be selected on the workpiece or outside the workpiece (such as on the fixture or lathe), but it must have a certain size relationship with the positioning datum of the part.The tool point should be selected as far as possible in the design basis or process basis of the parts, such as the workpiece positioning with the hole, the optional hole center as the tool point.The position of the tool is aligned with the hole so that the “in place” and “on the tool” coincide.In this way, you can better improve the efficiency of the knife, ensure the quality of processing.
4, the use of special lathe cutting oil, reduce the loss of tools
Lathe cutting oil contains cutting additives, through the release of additives can effectively protect the tool, reduce tool wear and improve the accuracy of the workpiece.By reducing the number of tool changes to improve the running time of equipment, thereby greatly improving the efficiency.
5. Reasonably select cutting parameters to improve the cutting efficiency of CNC machining allowance
In the selection of CNC milling machine cutting parameters, if it is rough machining generally to improve efficiency, but also to consider the economy, can choose a larger cutting depth and feed speed;If the semi-finishing and finishing, should guarantee the quality of the premise, both efficiency and economy;The feed speed should be set as high as possible when the cutting tool is in empty path.
6. Flexibly use various auxiliary functions of CNC machining.
