车床

Concurrently, it is estimated that will increase to numerical control knife rest demand greatly in recent years.

数控车床今后将向中高当发展，中档采用普及型数控刀架配套，高档采用动力型刀架，兼有液压刀架、伺服刀架、立式刀架等品种，预计近年来对数控刀架需求量将大大增加。

Carry on the numerical control transformation to the ordinary lathe. Mainly vertical and horizontal enter give system transform into by what microcontroller. The knife rest is transformed into the gyration knife rest that can be changed one hundred sheets automatically.

对普通车床进行数控化改造，主要是将纵向和横向进给系统改造成为用微控制器控制的，能独立运动的进给伺服系统；刀架改造成为能自动换刀的回转刀架。

The development trend of the numerical control knife rest is: With the development of numerical control lathe, numerical control knife rest begin to change one hundred sheets , electric liquid is it urge and urge direction develop while being servo to make up fast.

数控刀架的发展趋势是：随着数控车床的发展，数控刀架开始向快速换刀、电液组合驱动和伺服驱动方向发展。

The main to modify the lathe is to modify the portrait, horizontal enter to the system in the Whole modification process and choose the automatic knife rest and be processed the thread need by pulser.

整个改造过程主要对车床纵、横向进给系统进行改造，选用自动转位刀架，由脉冲发生器来加工所需要的螺纹。

In design in calculating, have lathe horizontal to enter give main composition part of organization to numerical more control authors of this text mainly: Ball guide screw vice, bring, bring wheel, exchange servo electrical machinery, vice guide and transfer to location knife rest, etc. design calculating or selecting type automatically in step in step.

在设计计算中，本文作者主要对数控车床横向进给机构的主要组成部件：滚珠丝杠副、同步带、同步带轮、交流伺服电机、导轨副及其自动转位刀架等进行了设计计算或选型。

Screw on the choice of friction loss, high efficiency, high precision, long life of the ball screw, the electrical selected stepper motor, motor and the ball screw with gear deceleration.The main to modify the lathe is to modify the portrait, horizontal enter to the system in the Whole modification process and choose the automatic knife rest and be processed the thread need by pulser. The whole control system with the CPU of JKW-15T is to control the machine for center, through a plait distance drive tool machine an equipments to carry on control to attain need of process degree.

整个改造过程主要对车床纵、横向进给系统进行改造，丝杠选用摩擦损失小，效率高，精度高，寿命长的滚珠丝杠，电机选用步进电机，电动机与滚珠丝杠用齿轮减速；刀架改造成能自动换刀的回转刀架，由脉冲发生器来加工所需要的螺纹；整个控制系统以JKW-15T型号的单片机为中心，通过编程对机床的驱动设备进行控制以达到所需要的加工程度。

Is the domestic machinery industry specializing in the production of ZGC series of large-diameter category lathe enterprises.

常州市振国机械有限公司是国内机械行业专业生产ZGC系列大直径类车床的企业。

The means of attaching a lathe chuck to different machine tools have been well standardized,so that chuks made by different manufacturers can be easily interchanged.

车床卡具配置不同机器母床的办法是定好型的，因此，不同生产厂商生产的卡具都能很容易的互换。

The lathe chuck is used for chucking the work,that is for clamping it so that it will rotate without wobbling while turning.The chunk,usually mounted on the headstock spindle,may have differnt sizes and construction.

车床卡盘用来夹紧工件这就是夹具，当工作台转动时夹具将旋转摇摆，卡盘通常安装在主轴箱心轴上可能会有不同的大小和结构。

The company mainly produces Dan Huangjia head, milling chucks, needle-strong milling chuck, chuck Modao Ji, instrument lathe chuck, chuck Zhitong, NC knife handle.

公司主要生产弹簧夹头、铣夹头、滚针式强力铣夹头、磨刀机夹头、仪表车床夹头、直筒夹头、数控刀柄。

The good news is that after formatting from the command line to FAT32 (format /fs:fat32 /a:4096 drive:) all but one of the problematic games that I tested work perfectly.

好消息是，从指挥线后格式化了FAT32(格式/曾荫权：了FAT32/答：4096年径：)所有问题，但其中的游戏测试工作，我很好。
