钻头是孔加工的主要刀具，在机械制造业中占重要地位，传统的麻花钻在生产上被广泛使用。

I produced the whole grinding high speed steel straight shank twist drill drill head copper series, drill steel series, drilling stainless steel series, parabolic drill (deep-hole drilling) series, carbide straight shank twist drill , high-speed steel red needles (red steel series, aluminum series red, red stainless steel series), round tools, kinds of non-standard, complex tools, cutting tools.

我公司生产全磨制高速钢直柄麻花钻头，硬质合金直柄麻花钻，高速钢冲针(冲钢系列，冲铝系列，冲不锈钢系列)，圆车刀，各种非标，复杂刀具，刃具。

It also elaborates on the reasonable choices of the geometric parameters and cutting parameters of the cutting tool materials, cutting tools to ream, drill and mill high strength steel and super-high strength steel.

在选择切削速度时，在工件材料的强度和硬度较高的情况下，应适当降低切削速度，减小刀具每齿进给量，按工件材料的强度选择铣削速度，按工件材料的硬度选择铣削用量。

The company has developed its own processing center, numerical control drilling machine, precision tool-specific processing equipment.

本公司拥有自己研制加工中心、数控钻床、刀具专用精密加工设备。

In this paper an innovative method for machining sculptured surfaces is presented. By using a disc cutter with a concave end instead of traditional ball-ended or drum-shaped tools, and adjusting the cut- ted axis to swing relative to the component being machined under some special rules, the envelope formed by the trace of the tool-nose may have the same derivative up to the third order as the required theoretical surface.

本文提出了一种加工自由曲面的新方法，即采用中凹的盘形铣刀取代传统的球头或鼓形铣刀，在每一行程中让刀具轴线相对于工件按特定的规律摆动，使得在垂直于进给方向的法截面中，由刀尖轨迹形成的包络面与理论曲面的法截线具有相同的1～3阶导数，从而在保持精度不变的前提下，使实际行程次数得以大幅度的减少。

In order to improve properties of shrub chipper and the quality of shrub chip, some factors influencing Salix end-grain cutting,such as rake angle,cutting thickness and moisture content of wood to be cutted were studied.

为了明确影响灌木材端向切削力的主要因素，改进削片机性能，提高灌木材削片质量，笔者研究了不同刀具前角、切削厚度和不同含水率对沙柳材端向切削力的影响。

The experiments have been performed in an engine lathe. The tool working orthogonal rake could be adjusted by a step motor according to the time varying parameters selected.

试验在普通车床上进行，刀具工作前角由微机通过步进电机按规定的时变参数控制。

These cemented carbides have bright future of application in aiguilles and ceramic tools.

热机械合金化制备的WC-Co硬质合金在钻井钻头、刀具领域具有广阔的应用前景。

The lab is focused on the new material science and engineering like diamond film to develop new and high-tech products, sucha as diamond filmed knives and aiguilles.

研究重点是：采用直流弧光放电等离子体化学气相沉积法技术与设备，开展金刚石薄膜等新材料科学与工程研究，开发金刚石涂膜刀具、钻具与设备等高新技术产品。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
