刀具

Results and Conclusion When the workpiece is of little elastic deformation, the discretization approach as proposed in this paper is appli- cable not only to the mathematical modeling for thread-cutting process, but to the modeling for processing simple workpiece by using complex cutter, and processing complex workpiece by using simple cutter.

结果和结论作者提出的离散化思路在工件弹性变形不大时，不仅适用于螺纹切削过程的数学建模，亦适用于其它复杂形状刀具加工简单形状工件和用简单形状刀具加工复杂形状工件时的数学建模。

Aim To exlore the method for describing cutter and workpiece, and the method for recording the shape and parameters of the cutting layer when complex workpiece is processed by using complex cutter, and to establish the math- ematical model for thread-cutting process.

摘 要：目的为了建立螺纹切削过程的数学模型，研究用复杂形状刀具加工复杂形状工件时，刀具和工件的描述方法以及切削层参数和形状的记录方法。

Jining-chuen, and Lin have two production bases. November 1997 passed the ISO9002 quality system certification of the assessment, is the largest in Shandong Province, the longest history of production and non-standard thread cutter knives factories, enterprises covering 268 acres and has 660 various sets of processing equipment, fixed assets 25 million yuan.

有济宁和泉林两个生产基地。1997年11月通过了ISO9002质量体系认证的评审，是山东省规模最大、生产历史最长的螺纹刀具以及非标刀具生产厂，企业占地268 亩，拥有各类加工设备 660余台，固定资产2500万元。

In actuator unit, the demand of parameters is analyzed, and it is brought forward that electric magnet is adopted as actuator, thermal resistance thread is adopted as cutter, and 5×5 cutter matrixes work synchronously for cutting the plastic film on each seedling.

在执行单元设计上，分析了其性能参数要求，提出利用电磁铁作为执行器，通电加热的电阻丝作为切破刀具，采用5×5的刀具矩阵同时动作使得电磁铁在动作时间内能处理每株棉苗上方的地膜。

First, according to the parts of materials processing operations, cutting tools and other relevant factors and choose the outline of the handle and part characteristics identify nine tools were cylindrical rough turning, cylindrical precision turning, external grooving cutter , internal thread cutter, Boring tool within the inner notch cutter, 93 ° left side knife, 93 ° right-side knife.

第一，根据本零件材料的加工工序、切削用量以及其他相关因素选用刀具及刀柄和零件的轮廓特点确定需要9把刀具分别为外圆粗车刀、外圆精车刀、外切槽刀、内螺纹刀、内镗孔刀、内切槽刀、93°左偏刀、93°右偏刀。

FS 33A is a mineral cutting oil blended from highly refined base oil and high quality EP additives including in-active sulphur and fatty oil. FS 33A can effectively improve tool life and surface finishing by preventing localised welding between chips and tools.

FS 33A 是一款矿物油切削油，由精炼的矿物油配合优质的不活性硫及脂肪等极压添加剂配制而成，能有效地防止刀具与碎屑之间的局部熔合，从而提高光洁度及刀具使用寿命。

FS 33 is a heavy-duty mineral cutting oil blended from highly refined base oil and high quality EP additives including active sulphur, in-active sulphur and fatty oil.

FS 33 是一款重负荷矿物油切削油，由精炼的矿物油配合优质的活性硫、不活性硫及脂肪等极压添加剂配制而成，能有效地防止刀具与碎屑之间的局部熔合，从而提高光洁度及刀具使用寿命。

Well, by the time they realized that they had the saw tooth knife in the mine field scene, it was too late and cost prohibitive to go back and re-shoot it.

但是这一切发生的太晚了，吉尔已经把道具制作好了，最后没有办法，史泰龙只有使用这个刀具进行电影拍摄，直到电影结尾部分博依刀型的刀具才送到拍摄组。

The Company is a professional manufacturer of various middle-grade alloy saw blade, combination tool molding, wood line tool manufacturers.

本公司是专业制造各种中高档合金锯片，组合成型刀具、木线刀具的厂家。

Simultaneously, on the premise of ensuring strength and toughness, the hardness and red-hardness are improved.

同时，在保证刀具强度和韧性的前提下，提高了刀具的硬度和红硬性。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
