Ten Aspects to Analyze Tool Breakage
Ten Aspects to Analyze Tool Breakage
(Ⅰ)
In the use of CNC router, tool breakage is a major headache, which is also almost inevitable.
We can analyze the cause of tool breakage from ten aspects:
Router bits, processing materials, CNC router, technology, processing depth, working engagement, clamping, cutting fluid and working environment nearby.
1. Router bits to cause tool breakage:
(1) Poor router bits quality;
Tool quality has great impact on process performance, efficiency and production cost, etc. Certainly, cutter with high quality have less frequency of tool breakage. But at the same time, high quality router bit is more expensive.
So, we suggest that:
It also depends on engraving materials:
a) To granite, it is necessary to use diamond tools. Such as 3D diamond tools, ball end diamond tools, flat end diamond tools, sintered diamond tools, PCD bits, etc.
If with common tools, it is nature to happen tool breakage.
b) To soft stone materials, common router bit is no problem;
② We can see that, suitable cutter selection is a way to reduce the case of tool breakage; so, it's better to buy high quality router bits. To such consumable, the better quality, the longer time we can use, and cost less on average;
③ Especially to stone CNC router, diamond cutter and PCD bits are more durable!
(2) Tool angle is too small;
(3) Cut into halves unevenly;
(4) Router bit parameter can divides into: cutting tool hardness, intensity, sharpness, exserted length and smooth degree of rake face;
① To hardness: it is related with coating material, grain number of tool material, cutter micro geometry angle;
② To intensity: the related factors are tool materials, the influence of alloy element;
③ Sharpness will affect grinding situation, the angle of rake and relief angle, etc;
2. Tool breakage caused by machining materials:
The hardness of processing materials is too big;
3. CNC router factor results in tool breakage –
(1) Spindle speed is too low;
If spindle speed is too low, the working engagement per tooth per revolution will become bigger, causing bigger cutting force and tool breakage.
In general, it is better with little higher spindle speed.
(2) Cnc router spindle with high speed is not vertical;
