Unfortunately, coolants create high coats in production and can be hazardous to the environment and human health.

当今机械切削加工领域大量使用切削液，目的是为了在切削加工过程中冷却工件、刀具和机械设备，此外还可以降低摩擦力和促进切屑排出切削区，但是由于使用了切削液，增加了生产成本，同时对环境造成污染，损害人们的身体健康。

Our products are capable of testing stainless steel sheets, cold-rolled steel sheets, steel strips, steel pipes, tinned steel sheets, galvanized sheet, aluminum alloys, brass, carbides, measuring tools, cutleries, cutting tools, stamped parts and other metal products.

沈阳天星试验仪器有限公司是专业生产便携式硬度计的企业，我们生产的便携式洛氏硬度计、表面洛氏硬度计、韦氏硬度计、里氏硬度计、涡流测厚仪等产品广泛应用于金属热处理、淬火、金属加工等行业，用于测试不锈钢、钢管、冷轧薄钢板、钢带、镀锡板、镀锌板、铝型材、铜管、硬质合金、量具、刃具、刀具、冲压件等产品。

The paper analyses the dements that inflences the processing precision of thin major axis on the base of its structure charac- teristics.

从细长轴的结构特点出发，分析了影响细长轴加工精度的因素，并针对产生误差的根源，从改变加工方式、工装结构和刀具参数等方面着手，提出了相应的解决措施。

The amount of lubricity is controlled for the particular machining operation and tool, such as tapping or face milling.

润滑剂的量是跟道具特定的机加工工艺和刀具而特设，例如开孔或面铣。

High-speed face milling with carbide-tipped cutters produces the best surface finish.

高速铣硬质合金核弹头刀具生产最好的表面光洁度。

The result indicates that the imbalance of cutter bring the most important influence of cutter's vibration, distance error of teeth impacts cutter's vibration under dynamic cutting force. This method had been applied in the development of high speed face milling cutter.

结果表明：刀具不平衡量引起的离心力对铣刀自激振动影响最大，齿距差对动态切削力作用下的铣刀振动产生重要影响，该方法已应用于高速面铣刀产品研发中。

Face milling in face milling, the cutter rotates about an axis that is generally at right angles to the surface being cut.

铣 面对铣削，刀具旋转轴的一个普遍成直角表面被切断。

In face milling the generated flat surface is at right angles to the cutter axis and is the combined result of the actions of the portions of the teeth located on both the periphery and the face of the cutter.

在两种铣削方法中，切屑的形成是不同的，逆铣过程中，刀具有推动工什丌使工件从工作台上提升的趋势，这种作用有助于消除铣床工作台进给螺杆和螺母间的间隙，从而形成平稳的切削。

When face milling is performed, the table can be moved longitudinally to feed the workpiece under or below the cutter

铣削端面时，为了将工件送到刀具底下或下方，工作台可以纵向移动。

According to the literature about the manufacture models of three kinds,radial feed- rolling cutter ,broach and Gleason cutter,the effect of centre point-centre line method,centre deviation method and oblique feed on qualified gear length were inspected.

根据滚刀、拉刀及格利森铣刀盘三类径向进给的制造模型相关文献，考察了中点中线法、中心偏移法、斜向进给对给出合格齿长的影响，指出了各类刀具的制造模型的异同，为这种研究提供了借鉴

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。
