    锉刀使用方法——锉削方法有几种?锉刀按用途不同DJ分为钳工锉(普通锉)、特种锉和整形锉三种。普通锉按其断面形状不同,又可分为扁锉、三角锉、半圆锉、方锉和圆锉等几种。锉削方法有几种你知道吗?以下小编为您介绍锉刀使用方法。
    How many kinds of filing methods are there? According to the different uses of the file DJ, there are three kinds: benchwork file (ordinary file), special file and plastic file. Ordinary files can be divided into flat files, triangular files, semi-circular files, square files and round files according to their cross-sectional shapes. There are several kinds of filing methods. Do you know? 

    1、基本锉法
    1. Basic file method. 
    粗加工锉削(粗锉):当加工余量大于0.5mm时,一般选用300mm、350mm的粗齿、中齿锉刀进行大切削量加工,以去除工件余量较多部分。
    Rough processing file (rough file): When the machining allowance is greater than 0.5mm, the general choice of 300 mm, 350 mm rough teeth, medium teeth file for large cutting amount processing, in order to remove more parts of the workpiece allowance. 
    细加工锉削(细锉):当加工余量介于0.5~0.1mm时,一般选用250mm、300mm的细齿锉刀进行小切削量加工,以接近工件的要求尺寸。
    Fine-machining file: When the machining allowance is between 0.5 mm and 0.1 mm, usually 250 mm, 300 mm fine-tooth file is selected for small cutting to close to the required size of the workpiece. 
    精加工锉削(精锉):当加工余量小于0.1mm时,一般选用200mm、250mm的细齿、双细齿锉刀以及整形锉刀对工件进行修整性加工,以达到工件要求尺寸。
    Finishing Filing: When the machining allowance is less than 0.1 mm, the general selection of 200 mm, 250 mm fine teeth, double fine teeth file and shaping file for workpiece finishing processing, in order to achieve workpiece size requirements. 
    全程锉削:锉刀推进时,其行程长度基本接近锉刀面长度。一般用于粗锉和细锉加工。
    Whole file filing: when the file is pushed, the length of the stroke is basically close to the length of the file surface. Generally used for rough file and fine file processing. 
    短程锉削:锉刀推进时,其行程长度仅为锉刀面长度的1/2~1/4。一般用于精锉加工。
    Short file cutting: when the file is propeled, the length of the stroke is only 1/2 to 1/4 of the length of the file. Generally used for fine file processing. 
    2、平面锉法
    2. Flat file method 
    纵向锉法:锉刀推进方向与工件表面纵向中心线平行的锉削方法。
    Longitudinal filing: a file cutting method in which the propelling direction of a file is parallel to the longitudinal central line of the workpiece surface. 
    横向锉法:锉刀推进方向与工件表面纵向中心线垂直的锉削方法。
    Transverse file method: file cutting method for advancing the direction perpendicular to the center line of the workpiece surface. 
    交叉锉法:锉刀推进方向与工件表面纵向中心线相交一角度a(35°~75°),并换向90°锉削以获得交叉锉纹的锉削方法。
    Cross-file method: A file cutting method in which the direction of file advancement intersects the longitudinal center line of the workpiece surface at an angle a (35-75 degrees) and the direction of file reversal is 90 degrees to obtain cross-file lines. 
    横推锉法:锉刀刀体与工件表面纵向中心线垂直,且推进方向与之平行的锉削方法。
    Horizontal pushing file method: A file cutting method in which the body of a file is perpendicular to the longitudinal center line of the workpiece surface and the direction of advance is parallel to it. 
    主动锉法:将扁锉刀作为被动体夹持在虎钳上,将形体较小的工件作为主动体用手握持放在锉刀面上,采用纵向推动或拉动进行加工的锉削方法。
    Active Filing: The flat file is clamped on the vise as a passive body, the smaller workpiece is held on the surface of the file by hand as an active body, and the file is processed by longitudinal push or pull. 
    3、曲面锉法
    3. Surface filing. 
    球面基本锉法
    Spherical basic file method 
    ①纵倾横向滑动锉法:锉刀根据球形半径SR摆好纵向倾斜角度a,并在运动中保持稳定。锉刀推进时,刀体同时作自左向右的滑动。注意:可将球面大致分为4个区域进行对称锉削,依次循环锉削至球面顶点。
    (1) Longitudinal and transverse sliding file method: the file is arranged according to the spherical radius SR and the longitudinal tilt angle a is kept stable in motion. When the file is propelling, the cutter body slides from left to right at the same time. Note: the sphere can be roughly divided into 4 areas, symmetrical file, then cycle to the top of the sphere. 
    ②侧倾垂直摆动锉法:锉刀根据球形半径SR摆好侧倾角度a,并在运动中保持稳定。锉刀推进时,右手同时作垂直下压锉刀柄的摆动。
    (2) Side-tilt vertical swing file method: the file is set according to the spherical radius SR tilt angle a, and keep stable in motion. When the file is advancing, the right hand swings the handle of the vertical downward press.
