Lathe transforms those who design system of 21 fore-and-aft feed to transform the feed that tears open oar primary machine tool box and delay board case, benefit calls feed of primary machine tool the installing hole of box and pin aperture, installation pace enters electric machinery and the casing to gear. Ball silk lever still finds a place for the position in former guide screw. The =1 P of every of computational cutting power of the estimation cutting force of workbench quality advocate electric machinery power, cadaver =7, 5; RI advocate transmission system overall efficiency. =0.

65; Coefficient of power of Ki feed system, blame =0.

96.

On Y slideway rub hold up coefficient, =17; W workbench action is in the gravity on slideway, = knowledge, =1309; For the quality of workbench. All previous =133.

61; The heart attachs most importance to force acceleration, heart 9.

The pitch of guide screw of ball of rotate speed T of guide screw of ball of computation of 8ItsJ0 ① intensity, 2= of =6 big load, sufficient 1= chooses the nominal diameter of ball guide screw to be to take type, 35061 father 2 left, namely double nut spacer moves unoccupied place style, the loop encircles a row inside, ball diameter is 3.

969 pitch are 6, its are rated dynamic load is 12847 continent 0=8.

53, reason strength is enough, the helix that plan add hill chooses ball guide screw at place promotes ② efficiency horn, =37, 9=10 of angle of friction, criterion the transmission efficiency of ball guide screw the design of the transforms transverse feed system design of system of 22 transverse feed and fore-and-aft feed system is similar, computation is omitted. The pace chooses what 31 fore-and-aft paces enter electric machinery to choose horn of affirmatory step pitch to take pulse equivalent winter of the system into what electric machinery reachs gear wheel, pulse, choose step pitch actor 0, the computation of quadrature of the motivation since = sets a pace to receive electric machinery equivalent laden moment of force is from negative grow force to be, according to principle of conversation of energy. Electric machinery place makes the photograph counterpoint of mobile component move. Pulse of 1= your Mm loses my power, even if guide screw is pulled,affect inertially with force, start pitching moment to call = .

Wide, 5.

Take safety factor to be. 3, criterion 4 with = 563, the step that takes for 5 photographs to working way enters electric machinery, basis with data, pick item 150 say 003 model the pace takes collect chance relatively interpose manages. Horn of step pitch of this electric machinery is 0.

751.

5, the biggest static torsion carries starting frequency to be for 20001 highest sky 2 manage together, transverse pace is chosen into electric machinery 13001 model, computation is omitted. Vertical,gear design is in up step pitch horn 9, =751.

5, equivalent of pulse of =6 of cadaver of pitch of ball guide screw, 1! Pace, enter pair of gear ratio that increase between electric machinery and ball guide screw to be =U= in the pace 9 cadaver, 0.

75 father 6=0.

The team is chosen namely 21 according to experience, gear modulus is taken 1.

5.

Manage together, transverse gear 21= is like 22=84 gear modulus for 1.

5 computation are omitted. CNC Milling CNC Machining
