For other uses, see Lathe (disambiguation). 
Not to be confused with Lath, a thin piece of wood. 
A lathe from 1911 showing component parts. a = bed, b = toolrest, c = headstock, d = geartrain to drive automatic screw shaft, e = pullies for belt drive from an external power source, f = spindle, g = tailstock. h = automatic screw shaft.

A lathe (pronounced [leɪð]) is a machine tool which spins a block of material to perform various operations such as cutting, sanding, knurling, drilling, or deformation with tools that are applied to the workpiece to create an object which has symmetry about an axis of rotation. 
Lathes are used in woodturning, metalworking, metal spinning, and glassworking. Lathes can be used to shape pottery, the best-known design being the potter's wheel. Most suitably equipped metalworking lathes can also be used to produce most solids of revolution, plane surfaces and screw threads or helices. Ornamental lathes can produce three-dimensional solids of incredible complexity. The material is held in place by either one or two centers, at least one of which can be moved horizontally to accommodate varying material lengths. Examples of objects that can be produced on a lathe include candlestick holders, cue sticks, table legs, bowls, baseball bats, crankshafts and camshafts.

答案:I'm with Al, particularly if you are chucking these items. Try a larger centre, check alignment (look for lateral or even vertical displacement as the centre enters the centre hole), or RELIEVE THE CUTTING PRESSURE (slow down feed). The bearings in the live centre aren't seizing due to excessive end thrust caused by heat expansion, are they? If the centre ceased revolving, it wouldn't take long to be overheated, seize in the material and shear off. I don't see the connection between work hardening and lubricant, but cast iron is usually machined without coolants, and easily machined. What type of cutting tools are you using?


答案:列举如下,仅供参考: 1.某些系统程序中数值后面需要加小数点,如果没有,单位以0.001mm进行计算。 2.某些系统程序需要调到所需程序后在进行加工,可能程序号未更换。 3.如果你是用的是仿真,请将就一下吧。 4.程序中如有复杂程序(宏程序,子程序或循环程序等),建议搞懂后再试验。 5.可能有某些特殊字符需要和控制面板配合使用,需注意。


答案:Y方向,是进刀量 但车车床称“Z”为纵向 X为横向 数洗才是XYZ  1自动走刀是有挂档 但很简单 不用的车床它们的挂档 配置不一样 一般在床身会表明,如6140 挂档 它是跟汽车挂档杆一样上下左右 挂档很容易 一接触老师或师傅会跟你说的 2车牙我想你要先看看车工的工具书较好些 车牙看你要加工的牙称(螺纹)有。三角螺纹、梯形螺纹 涡轮 劲节螺纹、公制英制、巨型螺纹、恩,。。相关的螺纹公式看工具书,车牙牙是测量牙深度 导程 公制还是英制 然后再车床设备上调节 表上找相应的牙 跟转速 。6140 AB档 这样说很抽象有个群96552641技师群 群里会有人给你答,找个师傅在身边教吧 这么好学 还要学校干嘛 就算你懂车床的具体操作方法 但你不懂工艺也没用的 也就不懂运用。
