May 10, 2010 - Seco Tools Inc. has announced the development of grade RX2000 with a surface hardness coating of up to 3,200 HV for increased productivity and tool life in Seco Precimaster reaming system applications, which feature exchangeable throwaway heads.

The new coating has a low friction co-efficient to minimize the risk of built-up edge and improve chip evacuation. In conjunction with a micrograin substrate, this super-thin (0.00008") coating provides enhanced surface finish, chip control and tool life, according to the company. When compared to other reaming grades, the RX2000 has reportedly shown a 200 percent increase in tool life in forged steel applications.

The RX2000 is well-suited for all materials except nonferrous, and works well in mass production application environments that can handle increased cutting data. The Precimaster reaming system combines a well-engineered body with internal through-coolant capability for through- or blind-hole finishing. Exchangeable reaming heads are available in sizes from 4mm to 60mm. The clamping system allows for accurate repositioning of the cutting head for H7 hole tolerance achievement. Additionally, the location of the clamp on the tool body makes it easy to change reaming heads without removing the tool from the machining spindle.

　　2010年5月10日，刀具推出这款{zx1}的铰刀-RX2000，由于表面有一层硬度达3200HV,性质稳定的涂层，在山高的Precimaster 铰削系统中，大大地增加了切削效率和刀具寿命，刀头为可更换式。

　　这种新型涂层摩擦系数小，减少了内置边缘的风险，利于排屑。与超细微粒基质结合在一起，这种超细微粒(0.00008")涂层增加了刀片表面的光洁度，利于切屑的排出，增加了刀具的寿命。跟其他的铰削牌号相比，RX2000 在锻钢应用中发挥了极大的作用，使刀具寿命提高2倍。

　　除过不含铁的材料， RX2000适用于所有的加工材料，并且适用于不同的加工环境。Precimaster铰削系统设计巧妙，通过内冷却液可以加工通孔或盲孔。刀头可换，刀头大小4mm到60mm不等。夹紧系统也充分考虑到对H7孔公差刀头的xx重定位。除此之外，刀体上夹紧的位置适当，使得它不需要从运转的机器上取下整个刀具即可容易更换刀头。
