0 4 cape is the following, want to often keep sharp. 6) to reduce radial cutting force, should choose lesser circular arc radius (R ° <0.
3mm) . The width that pours arris also should be chosen smally, take edge wide 6, - =0 5, (, for feed) . Angle of lathe tool of 1) of choice of condition of cutting of axis of common turning slightness chooses material of 2) razor blade to be Plo hard alloy. 3) cutting dosage: 5) suitable scope: Apply to the long and thin axis such as turning feed rod, guide screw. Cnc machine tool follows the contact of claw of tool carrier bearing and workpiece to answer with the adjustment of claw of tool carrier bearing proper. Had loosened to be opposite closely too cutting is adverse. The gap between the circle outside crossing a pine to point to workpiece and bearing claw is big.
Make workpiece so easily jumpy, the knife lets when causing cutting. Show bearing claw passes to workpiece pressure too closely big, shift work to lathe tool at the same time, such making that deepness of lathe tool cutting is far from a tip as feed, workpiece cut sex is abate and deepen, the workpiece diameter of result cutting is reduced. When should moving to go up to the circle outside workpiece diameter reductive with tool carrier, below the active force of lathe tool, workpiece fork can let a lathe tool.
Make cutting deepness is reduced, fork of result workpiece diameter can increase. Circulate for many times so, workpiece forms rings body. If discover afore-mentioned circumstances, answer to be amended in time. Correction method appropriate is new the circle outside car bearing place, adjust bearing claw. The spare parts trains the circle outside machining measure 1) to clip workpiece, the car is planar, drill central hole. 2) follows tool carrier in the installation on saddle of bed of Cnc machine tool, amend bearing claw. 3) places to follow tool carrier bearing to be in in the car on workpiece outside round. 4) adjusts the circle outside following claw of tool carrier bearing and work to be contacted gently. 5) receives knife car full-length outside round. One measure 5) repeats afore-mentioned measure 3) for many times, till turning ends. When the problem of easy generation and axis of slightness of car of machine tool of note 1) Cnc, pouring cutting fluid wants enough, prevent workpiece heat to be out of shape, also handle a lubricant function to bearing claw at the same time. Answer when 2) thick car circle of car of primary feed of work semifinished product, can affect the regular job that follows tool carrier otherwise. 3) is in cutting process, want to notice top Zhi Dingsong tightens rate at any time. Its check a method is: Actuate lathe makes workpiece rotates, hold circumgyrate center with right hand big toe and forefinger rotational part, when the tip can stop to turn; should loosen the hand points to, the tip can restore roll, this explains top degree of tightness is proper. Discovery is like when 4) turning oscillatory, the ringer with an appropriate weight can be covered on workpiece.
Or hang base of a gear to wait, remove disappear display vigour so likely to use. 5) long and thin axis is taken makings should straight, increase turning difficulty otherwise. The long and thin axis that 6) turning ends, must a string of 1 rise, bend in case. Appropriate of axis of 7) car slightness uses 3 claw to follow tool carrier and bedspring circumgyrate tip and turning of back feed law. CNC Milling
