6 Last Ways to Enhance Cutting Working Efficiency
What some other methods can we use to enhance cutting efficiency? Let's learn more skills now:
7. Design simple and easy sharpening clamp.
Clamped face milling cutter has high efficiency, easy to use, so it is very popular and well received by the CNC equipment operators. But the cutter blades waste largely, with high cost of using, and in most cases, the breakage of cutting tools blade is as a result of cutting edge wearing, so the re-sharpening and re-use of tools blade is important to manufacture factories, and they can get good economical benefits.
Solid carbide bits have high hardness, with low grinding efficiency. If we take single knife grinding cutting, it will not reach the purpose of saving. Therefore it is necessary to design the router collets of simpleness and high efficiency, to realize clamping multiple router bits in one time.
8. The selection of processing mode.
The processing mode is divided into 2 types: down cutting and up cutting. To the CNC machining centers, the mechanical drive system and structure itself have higher precision and rigidity, small friction coefficient of relative motion surface, small transmission parts space, small movement inertia, and suitable damping ratio, so it can adopt down milling way to improve working efficiency.
Besides, according to many years’ experience of machining operating, down cutting mode is able to increase more than 1 times of tool life than up cutting. If use asymmetric end milling way, engraver tools life can be even increased about 2-3 times.
9. Choose appropriate and reasonable processing route.
Setting correct, compact, and easy processing route is the foundation of guaranteeing working quality and improving efficiencies. When programming, the main principle to confirm machining route is:
1) Should guarantee spare parts working accuracy and surface roughness demands.
2) Should try to shorten machining path, reduce tools free travel move time.
3) Should make numerical computation simple, and code segments by low numbers, to decrease programming workload.
10. Workpieces clamping selection.
1) Should try to use combination router collets.
2) Because common router collets chuck has poorer flexibility, and relatively lower position accuracy, so in the condition of mass production and high demand of machining precision, we can design professional and specialized clamps.
3) Should be helpful to router bits changing and online measurement, in order to avoid collision.
11. Ancillary equipment must be complete and matching.
To lower tolerance.
12. Operating staff technical skills and knowledge training.
Working efficiency largely depends on the proportion of milling time accounting for whole service time. The bigger ratio is, the higher efficiency is.
In actual production, because of operators’ low technical level, unskilled handle, too long program debugging and work-piece changing time, result in the low processing efficiency.
Besides, they have too little professional knowledge, lack scientific guidance of the numerical control machining principle, technology, milling cutter selection, and cutting parameters setting. So build a well-established training system, strengthen technicians learning of theoretical knowledge, and enhance technological communications within and outside the enterprise, it is very necessary!
