Master Carbide 公司发展了一种新型半圆丝锥,其结构特点是,可大大增加容屑空间.这种丝锥是直接烧结成成品尺寸,螺纹不需进行磨制,所以价格可与高速钢丝锥相竞争,并且能显著提高刀具寿命.此种丝锥用在易于使刀具损坏的材料上攻丝,价值特别大,而且会大大降低刀具成本和正常攻丝工序的停机时间,若改变其前面和控制切屑的几何形状,则可用于任何材料的攻丝工序,该公司现有1/4″—20″标准牙形的丝锥试样.

Master Carbide has developed a new type of semi-circular taps whose structural features are to greatly increase the chip space. This type of taps is directly sintered to the final product size without the need for grinding of the threads, so the price can compete with high-speed taps, And can significantly improve tool life.This type of tap is particularly valuable for tapping on tools that are susceptible to damage to the tool and can significantly reduce tool costs and downtime for normal tapping processes if the geometry of the front and control chips is changed Shape, it can be used for any material tapping process, the company existing 1/4 “-20” standard tooth-shaped tap sample.
