        6140普通車床如何自動走刀?數控車床自動走刀是什

        ? 問:6140普通車床如何自動走刀?
        答案:我可以很負責人的告訴你,是你在車外圓時光杠不轉。是絲杠在轉。仔細看看。把扳手扳至光杠檔位。車絲時自動走刀是掛絲桿進給,并合上拖板箱上的開合螺母手柄實現自動走刀。車外園自動走刀則要掛光桿進給,合上拖板箱上的縱進刀或橫進刀實現縱向或橫向進給。掛光桿或絲桿的轉換手柄不在拖板箱上,而在走刀箱上。

        問:Does anyone have a background about a center lathe?

        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 [le?ð]) 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?

        問:普通車床在用頂針車削軸類工件時為什么會產生橢圓,該怎么消除
        答案:普通車床在用頂針車削軸類工件時產生橢圓,可能是床頭箱主軸間隙過大,拆開軸承壓蓋重新調整,或更換軸承.也可能是頂尖孔不圓,需要修頂尖孔.

        問:數控車床自動走刀是什么原因?
        答案:列舉如下,僅供參考: 1.某些系統程序中數值后面需要加小數點,如果沒有,單位以0.001mm進行計算。 2.某些系統程序需要調到所需程序后在進行加工,可能程序號未更換。 3.如果你是用的是仿真,請將就一下吧。 4.程序中如有復雜程序(宏程序,子程序或循環程序等),建議搞懂后再試驗。 5.可能有某些特殊字符需要和控制面板配合使用,需注意。

        問:工件車床加工出現錐度和橢圓怎么辦
        答案:錐度可通過調刀架的角度來實現。橢圓的話,如果是普通車床,只能用仿形法,即找一個橢圓的靠模來加工。另:錐度也可以通過仿形法來實現。

        問:普通車床怎么樣操作才能自動走刀?和車削螺紋時對車床的具體操作步驟
        答案:Y方向,是進刀量 但車車床稱“Z”為縱向 X為橫向 數洗才是XYZ  1自動走刀是有掛檔 但很簡單 不用的車床它們的掛檔 配置不一樣 一般在床身會表明,如6140 掛檔 它是跟汽車掛檔桿一樣上下左右 掛檔很容易 一接觸老師或師傅會跟你說的 2車牙我想你要先看看車工的工具書較好些 車牙看你要加工的牙稱(螺紋)有。三角螺紋、梯形螺紋 渦輪 勁節螺紋、公制英制、巨型螺紋、恩,。。相關的螺紋公式看工具書,車牙牙是測量牙深度 導程 公制還是英制 然后再車床設備上調節 表上找相應的牙 跟轉速 。6140 AB檔 這樣說很抽象有個群96552641技師群 群里會有人給你答,找個師傅在身邊教吧 這么好學 還要學校干嘛 就算你懂車床的具體操作方法 但你不懂工藝也沒用的 也就不懂運用。
