CNC engraving tool has greater progress from 9 years of recent ability on domestic development, relevant processing factory and use unit hour are staring at the tendercy of manufacturer with the eye of acumen, this also is as manufacturer of main engine of vulture mill aircraft not at all dare lax real reason place. Want to choose appropriate equipment of course as the user, if type selecting is undeserved, not only cannot make money to make be immersed in the agonized situation that works for the machine instead. Is so what kind of machine tool just good machine tool? We know the definition that is good machine tool is such: The machine tool that can return investment in short-term adduction just is good machine tool.

The design service life of numerical control machine tool is 7 years commonly, the service life that basically is numerical control respect is accurate, so beautiful money and the scale relation that earn money will affect your business directly, so anatomize function undertakes type selecting is the requirement of significant investment.

The name that there is vulture mill opportunity in foreign early (CNC Engraving And Milling Machine) , tell the one part that vulture is mill strictly, it is to buy engraving tool to still buy type of numerical control mill machining center is the question that often should ask his. Additional, still have at present the machine tool of high speed cutting of be current (HSC MACHINE) . Still let us make clear 3 type of Hunan distinguish above all: 1, - - the treatment facilities of the work that numerical control mill and machining center use at finishing bigger milling to measure 2, - - machine of mill of numerical control carve is used at completing lesser milling volume, or the treatment facilities of soft metal 3, - - machine tool of high speed cutting is used at finishing medium milling to measure, the treatment that and fall the burnish quantity after milling is lowest equipment

The structure that analyses afore-mentioned equipment deep can help us make right choice

One, - - from mechanical angle The mechanical cent of the machine tool is two parts, mobile part and not mobile part: Workbench, slide, the cross spends a stage to wait for mobile part, bed, pillar to be not mobile part 1, - - numerical control mill machining center: Sex of steel of blame shift part asks sex of steel of first-rate mobile part asks first-rate advantage: Can have heavy cut; Defect: Because mobile share is same giant, sacrificed machine tool flexibility, helpless to tiny part and fast feed. 2, - - sex of steel of part of shift of blame of machine of mill of numerical control carve asks sex of steel of very mobile part wants with below the problem before be neatly, as far as possible a few lighter, maintain certain steel sex at the same time. Advantage: Can undertake comparative petty treatment, treatment precision is tall. Can undertake to soft metal high speed is machined; Defect: Because steel sex is poor,have heavy cut impossibly so. 3, - - it is good that machine tool of high speed cutting is not sex of mobile part steel to ask sex of steel of first-rate mobile part asks to compare, and as far as possible deft. Advantage: The cutting of the particle in can undertaking (the exemple is general the flat bottom knife of φ10, to 45 steel (300) deep-felt deepness with 0.75 had better) ; Defect: Use correctly below can develop efficient, low cost, make burnish quantitative change is few. Incorrect use, can make the reject accumulation of cutting tool is like hill immediately. How to accomplish from machinery above light, rigid very contradictory requirement, the key depends on the kongfu on rigid structure. 1, - - the meshy framework that bed body uses muscle of on any account to cooperate, some uses what connect honeycombly directly inside 6 horn are meshy structure 2, - - exceed wide pillar and beam, the symmetry that because its are wonderful,everybody knows the structure of dragon door type and admirable steel sex are done to head all the time by manufacturer of equipment of high speed cutting choose a structure. 3, - - as prominent as numerical control mill to moving to have partly different place is broaden the distance between a lot of slideway and slideway, in order to overcome the problem of undesirable moment of force. 4, - - tell from material used Mi Han commonly that is cast-iron, namely be pregnant with is cast-iron, be in pouring it is certain to be joined when molten iron proportional silicon (Si) the inner structure that changed iron thereby, those who make more be able to bear or endure punch, have on tigidity rise significantly. 5, - - the powerful concussion that the part moves to be not when the tigidity of the machine tool basically takes mobile part to move in high speed with Yu Ke, requirement of lever of slideway, silk is so a few thicker, and strengthen join part tigidity
