How to highlight the advantages of five axis CNC machining for small batch parts
In the cnc processing industry, the cnc processing of batch parts can show processing advantages, one of which is efficiency.
Because cnc machining batch parts first needs to save time, efficiency can reduce many costs, the important thing is to save time. Generally, the efficiency of cnc machining batch parts with three-axis machine tool is relatively low. First, clamp several times. If the part has four sides, the whole workpiece needs to be machined with six sides and clamped six times.
5-axis CNC machining
Regardless of the processing efficiency, clamping takes a lot of time, and the allocation of multi face processing requires more machines. If the side that is not easy to process is encountered, the fixture needs to be made to cooperate with the processing, which is not ideal in terms of cost and efficiency. However, five axis linkage machining has improved many problems. First, efficiency. Five axis CNC machining and clamping do not require so much effort.
It only needs one clamping to complete the processing of multiple surfaces, which improves the efficiency, reduces the pressure of CNC on-site clamping, and also reduces a lot of time costs for fixture matching processing. Generally, a three-axis machine tool needs six times of clamping to complete the processing of the workpiece. Basically, a five axis machine tool can complete the processing of the whole workpiece only by clamping it twice.
Therefore, the efficiency of 5-axis cnc machining has a great advantage, followed by quality. On the premise of ensuring efficiency, the quality of batch parts must be guaranteed first.
In case of quality problems, the whole batch of workpieces will be repaired And even scrapped in batches. Therefore, before improving efficiency, we must first ensure good quality. Due to the large number of clamping times, there will be some errors when machining the side faces of multi sided batch parts with three-axis machine, such as improper connection or processing failure, and sometimes it needs to be arranged outside to complete the processing.
On the one hand, it has nothing to do with the cost increase, but there will be some defects in quality. However, in five axis cnc machining, some complex sides can provide cutting environment for the tool according to the change of workpiece angle. Since the workpiece does not need to be disassembled for calibration, the error when machining the side surface is greatly reduced.
