    (1)根据加工工件不同几何形状和具体情况,选择锉刀并安装好锉刀柄,锉刀柄安装孔的深度约等于锉舌长度,孔的直径应使锉舌能自由插入1/2的深度。
    (1) According to the different geometric shapes and specific conditions of the workpiece, select the file and install the file handle. The installation hole depth of the file handle is about equal to the length of the file tongue. The diameter of the hole should enable the file tongue to insert 1/2 depth freely.
    (2)装夹工件,工件装夹在台虎钳钳口的中间,略高于钳口。对于夹持已加工表面时,垫以铜片或锌片。对于易于变形工件,使用辅助材料设法装夹。
    (2) clamping the workpiece, the workpiece is clamped in the middle of the vise jaw, slightly higher than the jaw. For clamping the machined surface, copper or zinc plates are used. For deformable workpieces, auxiliary materials are used for clamping.
    (3)锉削方法,正确锉削方法包含以下三个内容:
    (3) file cutting method and correct filing method include the following three contents:
    1)锉刀的提法:由于各种锉刀的大小和形状不同,因而其握法也不同。
    1) the formulation of file: because the size and shape of various files are different, their grip methods are different.
    ①大锉刀的握法:右手心抵着锉刀术柄的端头,大拇指放在锉刀术柄的上面,其余四指弯在下面,酉己合大拇指捏住锉刀术柄。左手则根据锉刀大小和用力的轻重,有多种姿势。
    Grasp the big file: the right hand against the end of the handle of the file, thumb on the top of the handle of the file, the rest of the four fingers bent below, the thumb together to grasp the handle of the file. The left hand has multiple positions according to the size and strength of the file.

    ②中锉刀的握法:右手握法与大锉刀握法相同,左手用大拇指和食指捏住锉刀前端。
    Hold the middle file: the right hand grip is the same as the big file grip. Hold the front end of the file with the thumb and index finger in the left hand.

    ③小锉刀的握法:右手食指伸直,拇指放在锉刀木柄卜面,食指靠在锉刀的刀边,左手几个手指压在锉刀中部。
    Hold a small file: right index finger straight, thumb on the file wooden handle divination surface, index finger against the edge of the file, the left hand several fingers pressed in the middle of the file.

    2)锉刀的使用姿势:使用锉刀时要站立自然,便于用力,身体重心应落在左脚上,伸直右膝,脚始终站稳不移动,左膝随锉削时的往复运动而屈伸。锉削时,两脚站稳不动,靠左膝的屈伸使身体做往复运动,手臂和身体的运动要互相配合,并要使锉刀的全长充分利用。开始锉削时身体要向前倾斜10度左右,左肘弯曲,右肘向后。锉刀推出1/3行程时身体向前倾斜15度左右,此时左腿稍直,右臂向前推,推到2/3时,身体倾斜到18度左右,最后左腿继续弯曲,右肘渐直,右臂向前使锉刀继续推进至尽头,身体随锉刀的反作用方向回到15度位置。
    2) The use of the file posture: when using the file to stand naturally, easy to exert force, the body center of gravity should fall on the left foot, straight right knee, foot always stand firm and do not move, the left knee with the file movement and flexion. When filing, both feet stand still, lean on the left knee flexion and extension so that the body to do reciprocating movement, arm and body movement to match each other, and to make full use of the full length of the file. When you start filing, you should tilt your body forward about 10 degrees, bend your left elbow and back your right elbow. The left leg is slightly straight, and the right arm is pushed forward. When pushed to 2/3, the body tilts to about 18 degrees. Finally, the left leg continues to bend, the right elbow gradually straight, the right arm forward so that the file continues to advance to the end, the body with the direction of the file reaction back to 15 degrees position.

    3)锉削力的运用:锉削平面时,为使锉刀在工件上保持平衡,必须使右手的压力随锉刀的推前而逐渐增加,左手的压力则相反。在锉削过程中,锉刀的运动应平直,其关键在于不断地调整左右手的压力,使锉刀两端的力矩平衡。锉削回程时不加压力,以减少锉齿的磨损。锉削力的正确运用,是锉削的关键。锉削的力量有水平推力和垂直压力两种。推力主要由右手控制,其大小必须大于切削阻力才能锉去切屑。压力是由两手控制的,其作用是使锉齿深入金属表面。两种压力大小也必须随着变化两手压力对工件中心的力矩相等,这是保证锉刀平直运动的关键。方法是:随着锉刀推进,左手压力应由大而逐渐减小,右手的压力则由小而逐渐增大,到中间时两手相等。
    3) Application of Filing Force: In order to keep the balance of the file on the workpiece, the pressure of the right hand must be gradually increased with the advance of the file, while the pressure of the left hand is opposite. In the process of file cutting, the movement of the file should be straight, the key is to constantly adjust the pressure of the left and right hands, so that the two ends of the file torque balance. No pressure is added during file return to reduce wear of file teeth. The correct use of filing force is the key to file cutting. There are two kinds of force for file cutting: horizontal thrust and vertical pressure. Thrust is mainly controlled by the right hand, which must be larger than the cutting resistance to file the chip. The pressure is controlled by two hands, and its function is to make the file teeth go deep into the metal surface. The two kinds of pressure must be equal to the moment of the center of the workpiece with the change of the pressure of both hands, which is the key to ensure the straight motion of the file. The method is: as the file advances, the pressure on the left hand should be gradually reduced from large to small, the pressure on the right hand should be gradually increased from small to equal in the middle.
