Ten Aspects to Analyze Tool Breakup
Ten Aspects to Analyze Tool Breakup
(Ⅱ)
Tool breakup, actually because the strain on the router bits had changed, or some other big effect factors.
Today, let's continue analyzing tool breakup from ten aspects:
4. Tool breakup due to technology:
(1) Feeding speed or processing speed is too high:
High speed also has certain effect on service life of long router bit.
Because, even if feed speed is very fast, the rotation speed of tool bit is still very slow;
especially to granite, too fast feeding speed is equivalently like a death sentence to granite router bits.
So, speed is a factor to cause tool breakup.
(2) Machining program:
Whether the machining allowance is reasonable, or has stepping allowance. Thus, changing cutting force will lead to shock and tool breakage during processing.
So, it is necessary to increase semifinishing;
5. Tool breakup caused by processing depth:
Engraving depth can also results in tool breakage.
Usually, we prefer deeper carving depth to cnc router, however, please pay attention to slow down at the same time!
6. Too big working engagement cause tool breakup:
The cutting capacity is unable to keep pace with high setting feed speed and rotate speed;
7. Check whether router collets & collet adapter, nut are in good condition;
8. Clamping way to cause tool breakup:
(1) The clamping length is not enough, causing the shake of miniature end mills;
(2) The expansion amount of cutter is too big, which is more to the point;
9. Cutting fluid:
(1) The function of cutting fluid is: lubrication, cooling, cleaning, rust protection, etc.
(2) So, we should clean and put cutting fluid regularly;
10. Working environment nearby:
The relative factor to cause tool breakup is:
(1) Whether there is vibration source (focus) around;
(2) If the supply voltage is stable;
In the future, we could analyze tool breakup from the above ten aspects, and combine the actual situation.
