File cuts operation brief introduction

2 ～ Mm. 1) the operation file of file plane cuts plane is file in cutting the mainest operation. Want file to give flat plane, must make the motion of the file maintains a level. Flat be to rely on in file to cut the pressure that two tactics adjusts gradually in the process to achieve. Alternate file method can be used when rasp, such not only file is gotten fast, and cut in the file of workpiece surface rugged trace can be shown on the face, easy file gives reason accurate plane. After waiting for basic file to make the same score, can use fine file or smooth file to repair light in order to push file way (graph 1) . Graph 1 2) outside file of circular arc face is cut common outside file of circular arc face cuts a method to have suitable file law and law rolling file (graph 2) . Efficiency of cutting of suitable file law is tall, comfortable at rough machining; The round dambered surface that file of law rolling file gives won't give the appearance of existing edges and corners, use at the finish machining phase of circular arc face commonly. Graph 2 outside the file of circular arc face cuts methodological inspection man to provide reach its to use inspection man to have bevel protractor of blade feet, square, cursor to wait. Blade feet, square can examine the linearity of workpiece, flatness and verticality. The introduction examines with blade feet below the method of workpiece flatness. 1) blade feet perpendicular lean closely in workpiece surface, be in fore-and-aft, transverse check with diagonal direction successive (graph 3) ; Graph 3 examine with blade feet flatness 2) when examining, if blade feet and workpiece plane are pervious to light faint and even, criterion this workpiece flatness is eligible; If enter light intensity to lose differ, explain this workpiece plane is uneven. Can rely on closely to be in the feet that use stuff to insert in blade feet and workpiece, the error that can decide flatness according to the ply of feet of a place of strategic importance (graph 4) . Graph the 4 feet that use stuff measure flatness error value CNC Milling CNC Machining
