tapping
Description:
Tapping is a Machining thread Cutting process that uses a tap to produce internal threads. The taps are relief-ground to reduce friction Work. During the tapping process, the teeth at the tip of the tap perform most of the cutting action. The rest of the tap, which is slightly tapered, serves as a guide. Tapping can be achieved either by hand tapping or using a machine. Hand tapping involves a set of taps, usually three, each of which performs part of the tapping action: First tap (50 percent) Second tap (30 percent) Final (finish) tap (20 percent) Machine tapping usually involves a single tap. Due to poor chip removal, unfavourable Friction conditions and the associated risk of tool breakage, machine taps work at low tapping speeds.

Example sentences:
- Positioned in an instant and tightened with the self-tapping screw.
- Use a crosshead screwdriver to remove the two self-tapping screws.
- However, there is no need to do this in order to remove the self-tapping screws of the steel side panel.

攻丝
Description:
攻丝是指使用旋塞生产内螺纹的切削螺纹工艺。旋塞经过铲磨以减少摩擦作用。在攻丝工艺中，旋塞端齿执行大多数的切割动作。旋塞其余部分稍微带有锥度，作为导套使用。 攻丝可以用手动或通过机器来实现。手工攻丝要使用一组旋塞，通常需要三个，其中每个执行攻丝行动的一部分： 头锥（50 %） 二锥（30 %） 精攻（20 %） 机械攻丝通常只需要单个旋塞。但由于排屑不畅，不利的摩擦条件和刀具破损的相关风险，在低速下执行机械攻丝。 旋塞
