Four major cutting method:
- Precision micro turning
- Precision micro milling
- Precision micro fly cut
- Precision micro drilling
Basic requirements for miniature cutters:
- Small work piece and micro machining part
In order to fit the characteristics of tiny machining, high machining accuracy and avoid interference between the work piece and the cutter, the whole work piece and the machining scale must be synchronized reduced.
- Sharp cutting edge
Under micro cutting conditions, in order to achieve a very small amount of material removed, the depth of cut and feed rate is usually in the micron level, the cutting edge should be sharp enough.
- Good quality of surface
Surface quality influences the performance of the micro-cutting tools a lot, poor surface quality will not only increase the frictional resistance and lead to the deterioration while fine cutting, but also weaken the toolstrength.
- Good quality of surface
Rotary tools like the small diameter of end mills and drills, micro-cutting is carried out under high spindle speed.The cutting part of cutters should have sufficient strength and dynamic characteristics, which are able to afford the high impact load.
- Rigid, anti-deformation ability
To ensure working accuracy, miniature cutters should have higher rigidity to reduce the deformation and rebound under cutting force.
- Good wear resistance, average wear process
The cutting part of the micro cutting tools should have enough hardness to ensure its abrasion resistance.Blunt cutter will not only affect its machining accuracy, but also happen processing glitches which will bring difficulty of surface finishing.
- High accuracy of dynamic balance
The run out feed rate of micro cutter is significantly greater than cutting for normal size... Under high spindle speed, the cutting edge between the cutting load is very uneven, the cutting force fluctuation is serious, the tip trajectory and accuracy of processing, the tiny end mills, drills and other rotary tool should have high accuracy of dynamic balancing.
- Accurate and reliable tool clamping
Small rotary tool installation error is the main factor to influence the machining accuracy and reliability. The tool clamping system should have high contact rigidity, accuracy of repeating position, and good speedy locking.
Material of micro cuttersIt is a very important mean to choose the advanced and applicable tool material, which may ensure the whole performance of micro tools .. The ideal materials for miniature cutters are diamond, fine grain and ultra-fine grain carbide.
