Milling machine is fore-and-aft filar lever pursues 2 mill rack moves be apart from hang annulus frame 2 mobile and fore-and-aft workbench is used on milling machine when mill rack, use graduation board law or axis of dividing head side to hang round of law to make fore-and-aft workbench moves commonly pitch. Can be these two kinds of methods, give error operation trouble, easily not only, and go because of installing dividing head to occupy the one part area of workbench, affect the installation of workpiece. Because if pursue,this was made 1 with the graph two kinds of when show 2 special rack move be apart from hang annulus frame, operate in outdated not only handy, and move the precision that be apart from is very tall also. The mill rack that the graph shows 1 times moves be apart from hang annulus wearing is to pass a pair of tine to count identical bevel gear 1:1Speed ratio mixes handwheel hang round of couplet. Should locate with hand push ahead 1, roll turns handwheel 5 hind, fixed position is located in the force answer of bedspring of have the aid of in the fixed position chamfer of handwheel, mix through bevel gear hang annulus transmission, drive workbench fore-and-aft guide screw rotates, make workbench fore-and-aft and mobile a pitch. Mill is different when the rack of modulus, change to be hanged differently annulus. Hang round of computation formula to be as follows: In type of Z4P of × of MZ2 of π of Z1 × Z3= : Z1, Z3 -- number of active teeth of a cogwheel; Z2, Z4 -- number of passive teeth of a cogwheel: M -- the modulus of rack (Mm) ; P -- pitch of fore-and-aft workbench guide screw (Mm) . Exemple: In the spur rack of M=5 of modulus of the milling on milling machine, workbench is fore-and-aft P=6mm of guide screw pitch, beg register number of teeth of a cogwheel. Solution basis is formulary 35 active teeth of a cogwheel count 730 × of × of Z4P66 of × of 50Z2 of × of 5=55 of × of 5=22 of M=(22/7) × of π of Z1 × Z3= Z1=55, z3=50; Passive tine counts Z2=30, z4=35. When using, will move be apart from hang annulus wear installation to be in milling machine workbench is right upright, hang those who had calculated installation of round of Z1, Z2, Z3 is being hanged annulus frame on, z4 installation is in workbench is fore-and-aft guide screw head, can undertake mill rack moves be apart from. What the graph shows 2 times also is rack of a kind of mill moves be apart from use hang annulus frame. Install it in milling machine workbench right end, with bolt 2 fixed go up in workbench. Driving gear and handle installation are on Ⅰ axis, gear Z2 and Z3 installation are on Ⅱ axis, gear Z4 installation is in workbench is fore-and-aft head of transmission guide screw. Should pull out fixed position is sold 7, shake pass on handle 6, drive workbench fore-and-aft guide screw is rotational, the pitch with make workbench fore-and-aft mobile and certain. The tine number as a result of Z1, Z2, Z3 and Z4 is respectively 29, 60, 52 with 48, the pitch P=6mm of fore-and-aft guide screw, hang annulus wear handle to turn, workbench is fore-and-aft and mobile 3.

14167mm. The distance that also is workbench shift namely is equal to the pitch of modulus M=1. Want to remember only: Handle turns, workbench is mobile the pitch of a modulus, handle turns 2.

5 when turning, m=2 of workbench shift modulus.

The pitch of 5. The rest may be deduced by analogy, the revolution of handle is equal to the modulus that machines rack. Operate not only so handy, and facilitating memory. CNC Milling
