刀具

The big gear's coefficient factor x2 and helix angle β are chiefly decided by t...

还叙述了点线啮合齿轮的特点，以及在相同z1、z2下，不同刀具参数时的变态图形以及它们的特点。

Hences, production process needs systems, which can detect, indicate and remove abnomal states of cutting tool and cutting process. In recent decades, much research work has been done in this area. Many monitoring and in-process detection methods and systems has been developed.

由于现代化的加工设备必须具备越来越大的柔性，并实现自动化运行，为了保证经济性，必须避免机床故障，因此，生产过程中需要能够检测、指示和排除切削刀具和切削过程异常状态的监控系统。

Depending on the method of manufacture, the gear may be of the continuous-tooth herringbone variety or a double-helical gear with a space between the two halves to permit the cutting tool to run out.

推力问题可以通过在同一坯见切削两组斜齿来克服。根据制造方法的不同，齿轮可以是连续人字形的，或者在两列斜齿之间留一间隙的双斜齿形的，以便切削刀具通过。

The micro hibachis or the Ginsu knives.

小型烤肉架还是Ginsu刀具？

Company Business: all kinds of mold, tools, mechanical parts of the vacuum, quenching, deep cold, nitrogen, carburizing, quenching and tempering, annealing, burning black, high-frequency and other conventional heat treatment, cymbals aging copper, stainless steel type of Bright Quenching and tempering, hardness testing, materials analysis.

公司经营范围：各种模具、刀具、机械零件的真空、淬火、深冷、氮化、渗碳、调质、退火、煲黑、高频和其它常规热处理等，钹铜时效、不锈钢类的光亮淬火和回火、硬度测试、材质分析。

This project is design the 50# knife hilts broach mechanism.It is cutting tool automatically clamp mechanism of spindle's inside for large-scale machining .

50＃刀柄拉刀机构为大型机床主轴内部刀具自动夹紧机构。

When cutting tool roaled of spindle's hole by manipulator or other ways,the pull nail behind of knife hilts is sent to ahead of tension bar of spindle. When receives the clamps signal, the pressure oil is passed over the oil cylinder left cavity of the spindle rear part, the piston to the right migration ,tension bar also to right migration by small dish shape spring function, the stell ball of ahead circumference of the tension bar shrink the distribution diameter by spindle's cone hole's force, holds on the knife hilts and pull nail colsely.

当刀具由机械手或用其他方法装到主轴孔后，其刀柄后部的拉钉便被送到主轴内拉杆的前端，当接到夹紧信号时，将压力油通入主轴尾部的油缸左腔，活塞向右移动，拉杆在碟形弹簧的作用下也向右移动，其前端圆周上的钢球在主轴锥孔的逼迫下收缩分布直径，将刀柄拉钉紧紧拉住。

I have attached a sketch of the two types of hobs.

我会做出这两种不同类型刀具的草图。

Pre-grinding gear hobs are widely used as the rough machining cutters for hardened gears with high precision, for they can leave undercut at the root of the gears'teeth.

由于磨前齿轮滚刀能够使得被加工齿轮轮齿根部产生一定量根切，所以被广泛用作高精度硬齿面齿轮的粗加工刀具。

In regard of the problems of large holes to be bored, deep boring into rock and complicated rock layers in construction of bored pile foundations of in\|water piers of main spans of Wuhu Changjiang River Bridge, selection and structural features of cutter heads and hobs of the boring equipment used are described.

针对芜湖长江大桥正桥水中墩钻孔桩基础施工中存在的孔径大、钻岩深、岩层复杂等问题，阐述钻孔设备中刀盘和刀具的选用要求及结构特征。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
