刀粒回收会受到哪些因素的影响?

影响数控刀粒回收质量的一些因素,骏豪数控公司小编给大家介绍的是影响刀粒回收质量的一些因素:当数控刀粒回收材料的硬度高时,耐磨性也高。但是刀片材料硬度越高,其抗弯强度和冲击韧性就会越低。下面简单介绍一下制作刀片两种材质。高速钢,因具有着很高的抗弯强度和冲击韧性,以及良好可加工性,目前仍是应用广的刀片材料之一。

Some of the factors that affect the quality of NC tool grain recycling, the Xiaobian of Junhao CNC company introduces some of the factors that affect the quality of tool grain recycling: when the hardness of NC tool grain recycling material is high, the wear resistance is also high. However, the higher the hardness of the blade material, the lower the bending strength and impact toughness. The following is a brief introduction to the two kinds of materials for making blades. High speed steel is still one of the widely used blade materials because of its high bending strength, impact toughness and good machinability.

涂层刀片,具有表面硬度高、耐磨性好、化学性能稳定、耐热耐氧化、摩擦因数小和热导率低等的特性,涂层刀片切削时可比未涂层刀片提高刀具寿命3~5倍以上,提高刀片切削速度20%~70%,提高加工精度0.5~1级,降低刀具消耗费用20%~50%。

The coated blade has the characteristics of high surface hardness, good wear resistance, stable chemical properties, heat and oxidation resistance, small friction coefficient and low thermal conductivity. Compared with the uncoated blade, the service life of the coated blade can be increased by more than 3 ~ 5 times, the cutting speed can be increased by 20% ~ 70%, the machining accuracy can be improved by 0.5 ~ 1 level, and the tool consumption cost can be reduced by 20% ~ 50%.

因此,涂层刀粒已成为现代切削刀片的标志,在刀片中的使用比例已超过50%。目前,切削加工中使用的各种刀片,包括车刀、镗刀、钻头、铰刀、拉刀、丝锥、螺纹梳刀、滚压头、立铣刀、成形刀具、齿轮滚刀和插齿刀等都可采用涂层工艺来提高它们的使用性能。

Therefore, the coated tool grain has become the symbol of modern cutting blade, and the use proportion in the blade has exceeded 50%. At present, the coating process can be used to improve the performance of various cutting tools used in machining, including turning tools, boring tools, drills, reamers, broaches, taps, thread combs, rolling heads, end mills, forming tools, gear hobs and gear shapers.

涂层刀粒有四种:涂层高速钢刀片,涂层硬质合金刀片,以及在陶瓷和超硬材料(金刚石或立方氮化硼)刀片上的涂层刀片。

There are four kinds of coated blades: coated high speed steel blades, coated cemented carbide blades, and coated blades on ceramic and superhard materials (diamond or cubic boron nitride).

但以前两种涂层刀粒使用多。数控刀头刀粒认为在陶瓷和超硬材料合金刀片上的涂层是硬度较基体低的材料,目的是为了提高刀片表面的断裂韧度(可提高10%以上),可减少刀片的崩刃及破损,扩大刀片应用范围。

However, the former two kinds of coated blades are used more frequently. It is considered that the coating on the ceramic and superhard alloy blade is a material with lower hardness than the substrate. The purpose is to improve the fracture toughness of the blade surface (which can be increased by more than 10%), reduce the chipping and damage of the blade, and expand the application range of the blade.
