1·To raise drilling performance of new micro-drill, a novel method was advanced for reginding of chisel edge.
为了提高新型微钻头的钻削性能，提出了一种适合于微钻头的横刃修磨原理及方法。
2·ZZM-A drill grinder simple structure, easy operation. One setup to complete grindings on drill web and chisel edge.
a型钻头磨刀机结构简单，使用方便，一次装夹就可以完成钻头的钻尖和横刃的修磨。
3·A pick, especially with one end of the head pointed and the other end with a chisel edge for cutting through roots.
鹤嘴锄，丁字镐一种鹤嘴锄，尤指一头尖而另一头有可割断根的凿边。
4·Based on the kinematic relationship of regrinding, a mathematical model was established for the chisel edge regrinding and the solution of grinding parameter was obtained.
根据刃磨的运动关系建立了新型微钻头横刃修磨的数学模型并求出了刃磨参数。
5·Point angles at outer corner and chisel edge corner are proposed to be used as the drill design parameters to determine the type uniquely and the relief Angle is used as a supplement parameter.
针对该钻型的特点，提出用钻尖主刃的外缘和横刃转点处的锋角作为其设计参数值。
6·This creates a chisel-like effect referred to as “edge-loading” that produces large volumes of microscopic metallic particles that can cause havoc in some patients.
这就形成了所谓的“关节边缘应力集中”（edge-loading）的凿状效果，从而产生大量的金属微粒，令患者苦不堪言。
