If photograph of main shaft center is down deviate Δ H to axle sleeve center, the clearance of axis and axle sleeve is inhomogenous (the 5) that be like a graph. Generation is so called " facing " phenomenon, at this moment the discharge discharge of each reduce expenditure air admission hole is different big, the aeriform discharge Q2 of apparent upside air admission hole is more than the aeriform discharge Q1 of bottom air admission hole. According to: of reduce expenditure principle? Condyle watchs grade of  of buy of Gou of Jie of Zou of  of extensive region of Shan natrium  ? and the pressure after shedding reduce expenditure of hidebound gas classics falls less. At this moment although axle sleeve is external baric Ps is same, but main shaft is circumferential the pressure that gets is not even (the 6) that be like a graph, just of this kind of unbalance can make main shaft is gone to eliminate " facing " phenomenal direction is mobile, main shaft can be automatic centering, have taller precision. Because be full of between axis and axle sleeve,compress gas at the same time, make the axis is in suspension condition in axle sleeve, its motion resistance is very little. If pursue,through the experiment vent one's anger body pressure Ps and T of main shaft torsion are shown 7 curves concern. Graph 5 graphs 6 can see from graph, when aeriform pressure ≥ 0.

The main shaft when 6MPa rotates smooth, axial motion is fluent, resistance is very little. Via 0.

6 ～ 1.

Circle of radial of main shaft of the test below 2MPa pressure is jumpy be less than 0.

015mm(spurs a plan 60mm of end panel of 7 axle sleeve is in) , the effect is very ideal. Graph 7 (4) 　 clip held partial HDT circular knife grinding machine to use the general 5C collet on international (the 8) that be like a graph, its are main advantage: ① collet of wide 5C of scope of application already was applied extensively to a lot of domains, and the standard on international is uniform, mutual and general. Clip of ② of graph 8 holds collet of 5C of aperture of limits big circle to be able to be placed greatly most hold 28mm, collet of 5C of Mohs taper hole can be placed hold cutting tool of power of awl of MS1 ～ MS4, the clip that suits to establish milling cutter very much is held. The precision with general collet of ③ precision tall 5C is in 0.

01mm left and right sides, and precision of collet of exact form 5C can be amounted to 0.

005mm. After handy 5C collet is, ④ operation pulls type collet, when using, after putting cutting tool, come back the pull rod after tightening but clamp cutting tool, operate the save labour when the province, very handy. (5) grinds the head to distribute the part after any cutting tool need. When processing harder data commonly, when; of the horn after the cutting tool with optional lesser choose is processing weaker data, can choose the actor after bigger cutting tool. Horny size wants to be ground by circular knife grinding machine after piece. Resemble traditional tool grinding machine, its wheelhead is not adjustable, emery wheel position is secured (the 9) that be like a graph, the size of the horn after cutting tool relies on to adjust top discretion will get, ever since horny: ? ? adjustment tip arrives 3.

188mm position, ability grinds the horn after giving 12 ° cutting tool. The operation rises special trouble. Differ with average tool grinding machine, the wheelhead of HDT circular knife grinding machine is adjustable type (the 10) that be like a graph, top height and main shaft center tall. The horn after HDT circular knife grinding machine is set adjusts handle and graduation mark, when using, change the position of emery wheel through turning handle comes, thereby conveniently the horn after set cutting tool, the operation is very handy. Graph 10 3.

Grinding principle is filled to circular knife grinding machine above all not less than 0.

The compression of 6MPa gas, at this moment the resistance of main shaft is very little, in order to make sure main shaft precision and main shaft motion are smooth. The 5C collet with appropriate installation establishs what what want grinding milling cutter clamp, adjust top position, fastigium letting a top is inside the helix chamfer that establishs milling cutter to carry a department, secure good tip next, wait because of tip and cutting tool center tall, so at this moment Duan Ren assumes horizontal position (the 11) that be like a graph. Edge axial drives main shaft gently, the attention should let tip and establish milling cutter to be contacted from beginning to end, at this moment the tip has oriented effect inside the helix chamfer that establishs milling cutter, main shaft along with establishs milling cutter to be able to make helix motion, this is the athletic contrail that place of grinding helix blade needs. Adjust good emery wheel to tilt by size of the role after establishing milling cutter degree, begin grinding, can grind the helix first flank that gives the role after containing so. After grinding first flank of a helix, do not want mobile wheelhead, take another the crucial point on the tip again, rely on a tip to direct likewise, ordinal grind all helix blade. When additionally grinding carries sword, can adjust main shaft, make establish milling cutter to carry blade to face emery wheel, the linear motion that passes workbench will finish.
