How to select the Jeefoo engraving cutter

The following account according to various materials respectively.

A. Copper, aluminum.

Is this kind of material is more soft, better processing of materials in general can processing all kinds of knives, copper is soft, but toughness is big, if the knife is not sharp burr, and if not convenient when the feed can under vertical spiral knife (feed quantity H < 0.5) generally do not break, the copper machining tool speed, feed can fast, thus improve the machining efficiency.

2. Steel material:

Steel type is more, we divided into three, respectively,

Soft, such as import ace, domestic 45 # steel, 50 # steel, this kind of material is more processing, also with domestic HSS tool such as AIA, imports such as LBK, STK, YG, etc can be easily machined.

Hard, such as 738, p20 and so on, with the AIA knife more difficult processing, with imported if YG can be processed, it is best to alloy knife or processing with a knife.

Very hard, such as 718, S136, oil, steel and metal mold using alloy steel, very hard, with the AIA knife is hard to processing, with YG classes can be processed, it is best to alloy processing with a knife.

Three, quenching or welding mold material:

Generally are not allowed to use HSS tool processing, convert alloy knife or a knife processing, speak above boils down to the table below:

Above is according to the processing material selection tool types, but each kind of cutting tool, have all kinds of knife size, how to choose the knife size and type?

As far as possible choose broadsword, because rigid knife, knife is not easy to break, processing quality assured.

According to the deep processing knife, the deeper the depth, the greater the knife, simply speak depth greater than 50 mm, tool more than 1/2 diameter, depth greater than 30 mm, tool than the diameter of a quarter

According to the workpiece size knife, workpiece, choose broadsword, instead choose knife.

Processing steel material, try to choose a knife, this kind of good rigidity, wear resistance, turning, machining efficiency is high, also compares the economy is the first choice of the processing of steel.

According to the type selection tools, open thick to use flat gong knife or - (knife), are not allowed to use R knife, smooth surfaces with QiuDao as far as possible, with a flat knife light surface effect is not good.

Choose cutter according to processing efficiency, of course, as the light plane with flat or round nose cutter with high efficiency, light slope surface with better.
