CNC non-standard precision parts processing technology

cnc machining hand plate, hand plate processing, first of all, non-standard precision parts CNC machining is very strict precision requirements, want to achieve ultra-high precision and smooth surface, so the choice of tool is very important, if the tool wear, parts machining surface smooth quality will be significantly reduced, in ultra-precision machining cutting, cutting speed is not limited by the speed of the tool. Manufacturing has long been committed to high-precision, difficult, easily deformed metal and plastic parts processing, light alloy and composite materials (such as aluminum alloy, carbon fiber, etc.) parts of small and medium volume manufacturing, as well as robot parts procurement and customization services.

Secondly, according to the transmission and cutting characteristics of the machine tool, it is preferred to select the small speed Z of non-standard precision parts, because the small speed Z can ensure that the appearance roughness reaches small Z and ensure the processing quality.

Nc machining of non-standard precision parts is selected according to cutting tools, speed, depth and other parameters. Previous experience tells us that the selection of tools with large front Angle can reduce cutting force, reduce deformation, and the length of contact time between tools and debris will be gradually shortened, reducing the basis of debris tumor composition.

The processing quality and efficiency of non-standard mechanical parts can be improved by rationally arranging the process flow. Non-standard parts processing production has its own set of technological flow, can improve the efficiency of NC machining.

Nc programming is the foundation of NC machining. The advantages and disadvantages of the workpiece processing program will directly affect the machining efficiency of the workpiece. Can skillfully use the inherent program combined with automatic programming, reduce the error of numerical control system, flexible use of the main program, improve programming speed, simplify the machining tool path.

Adjust the machine tool and fixture in advance to obtain the relative position of the tool should obtain the desired size. Don't try to debug and measure again and again. Adjust tool feed and cutting amount to reduce processing efficiency. When the axle rotates, the belt wheel drives. The pulley and axle will slip. Can be in the wheel shaft with a bit to scratch a mouth, the formation of adsorption force, prevent slipping. Bearing rotation efficiency should be improved, and high precision rolling bearings should be selected. Improve the precision and processing efficiency of the parts matched with bearings.

To transform the fixture, remove the jaws, flatten the two steel plates with the jaws, process two threaded holes on the jaws and the steel plates, pad them with thick hard copper plate, and fix them on the jaws with screws to form durable soft jaws. This protects the artifact. Usually, the workpiece is positioned before clamping. But for the workpiece with strong plasticity, clamping will cause the workpiece deformation. Therefore, for the workpiece with strong plasticity, we clamp it before positioning to limit its free movement.
