CNC precision machining is actually index-controlled machining. After the design drawings are written into the program, the computer is connected to the CNC machine tool, and the operation of the CNC machine tool is controlled through programming to complete the titanium machining of precision workpieces. CNC precision machining is mainly suitable for small batches, The machining of various types of workpieces, precision machining, and the materials used in it have strict requirements, and not all materials are suitable.
Precision machining, not all materials can be precision processed. For example, if some materials with too high hardness exceed the hardness of the machined parts, some special materials are not suitable for precision precision machining.
The first is the requirement for the hardness of the material. For some occasions, the higher the hardness, the better, but it is limited to the hardness requirements of the machined parts. The machined material should not be too hard. If it is harder than the machine part, it cannot be processed.
Secondly, the material is moderately soft and hard, at least one grade lower than the hardness of the machine part. At the same time, it also depends on the purpose of the processed device and the reasonable selection of the machine part.
advantage:
① The number of tooling is greatly reduced, and complex tooling is not required for titanium machining parts with complex shapes. If you want to change the shape and size of the part, you only need to modify the part machining program, which is suitable for new product development and modification.
②The machining quality is stable, the machining accuracy is high, and the repeat accuracy is high, which is suitable for the machining requirements of aircraft.
③The production efficiency is higher in the case of multi-variety and small batch production, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the best cutting amount.
④It can process complex profiles that are difficult to process by conventional methods, and even process some unobservable machining parts.
The disadvantage of CNC machining is that the cost of machine tools is expensive and requires a high level of maintenance personnel.
Finish machining is performed after rough machining self-inspection. After finishing titanium machining, workers should perform self-inspection on the shape and size of the processed parts: check the basic length and width dimensions of the processed parts of the vertical surface; measure the basic point size marked on the drawing for the processed parts of the inclined surface, and the worker completes the self-inspection of the workpiece and confirms the drawing The workpiece can be disassembled and sent to the inspector for special inspection only after it meets the process requirements.
