1、现代的刀具费用水平据最近统计,全世界金属切削加工成本约40兆日元,其中切削刀具成本占2%,约8000亿日元。二十年前使用硬质合金焊接刀具时,刀具费用占加工成本的30%,变化是巨大的。以目前的涂层刀片为例,如用双面三角形刀片(有6个切削刃)来切削中碳钢,切削速度为以往硬质合金刀具所用的速度,即100～150米/分,每个切削刃的寿命为150～200分,整个刀片的寿命可延长900～1200分/片。现行的刀片价格(随尺寸而异)如每片为1000～1500日元,则涂层刀片进行正常切削时所耗成本,每分钟约1～1.5日元。另外,近来切削加工的时间单价仅劳务费用一项,通常每
1, the level of modern tool costs According to recent statistics, the world’s metal cutting costs about 40 trillion yen, of which 2% of cutting tool costs, about 800 billion yen. Twenty years ago using carbide welding tools, tool costs accounted for 30% of the cost of processing, the change is huge. Taking the current coated blade as an example, cutting a medium carbon steel with a double-sided triangular blade (with six cutting edges) at a cutting speed of 100-150 m / min for the conventional cemented carbide tools Cutting edge life of 150 to 200 minutes, the entire blade life can be extended 900 ~ 1200 points / piece. Current blade prices (varies by size), for example, are 1,000 to 1,500 yen per piece, and the cost for normal cutting of the coated blade is about 1 to 1.5 yen per minute. In addition, the recent unit price of labor only a labor costs, usually per
