Boring machine workbench is blown grinding is one of methods that inspection man makes a working surface light make treatment. Its purpose is to reduce examine surface roughness of flat working face is worth, raise osculatory precision and geometrical precision, raise boring machine workbench thereby cooperate stiffness, lubricant function, mechanical benefit and service life, also use planar grinder and slideway grinder treatment to be achieved hard only, machine tool equipment and boring machine workbench the treatment craft of place. Alleged “ is blown grind ” , it is scrape is mixed abrade the union of two working procedure. Namely planar scrape —— is abrade show, —— of again planar scrape is again abrade show, such move back and forth, circulate alternately, run ceaselessly. Make the value mixes the surface roughness of surface of boring machine workbench of boring machine workbench form the error is reduced stage by stage; Osculatory precision, geometry precision rises stage by stage in run, arrive at a regulation continuously till the requirement. Grind as abrade as course of boring machine workbench later, of raised part examine what platform surface shows is macula completely, macula divides window, thick macula, weak macula. These macula are in in grinding, blowing is a variable. Run ceaselessly through successive alternant loop blow ceaselessly grind, macula by become less dense, by inhomogenous distributing turn into to distributing equably. Of macula evolve into a process, also be the surface bright and clean degree, the process that precision of watch surface contact, exterior geometry precision improves stage by stage. Right abrade show the macula that come out wants distinguish treat. Slash to the knife of thick macula scrape size should press thick, fine, essence together scrape of size of 3 phase regulation, its knife slash direction should be arranged with direction, progressively scrape is blown to macula total number. Classics is abrade after showing, 2 also blow macula total number with scrape of direction of crisscross of boring machine workbench. Point out, every rounds of scrape, knife slash crisscross, will affect surface of boring machine workbench otherwise bright and clean degree. Press to macula in scrape bright, thick, weak going up forcibly due the cent of weight, want forcibly to window, big thick macula big, want moderate forcibly to most thick macula, to weak macula, withhold do not blow, wait for below annulus when after showing, blackening, blow again, emphasize pointing out, be in to distributinging the window of brim of plane of boring machine workbench, corner. Because concealed cloth is little, it is oversight of person eye institute easily, easy leakage is blown. Because leakage blows a dot to be in,grind a workbench of abrade boring machine often supports when grinding, show of cloggy macula normally, can form macula to blow less phenomenon more. 3, boring machine workbench blows grind 3 phase: Blow in boring machine workbench grind in whole process, should experience commonly thick blow, fine blow, essence of life shaves 3 level. Boring machine workbench is thick shave level: Thick the first job that blow should be solved first form error problem. Lathe is for instance smooth the two end of slideway of board swallow end parallelism, if be not solved good first, stay thick parallelism is solved again after been blow, not only take a lot of work take time and time limit for a project of incur loss through delay. Thick drawknife mark wants bounty, want ground of bold and resolute to undertake. To every the dot is blown only do not blow 2 times. Knife slash direction is to be the same as directional gradate, every rounds of commutation. Grind through circulating to be blown ceaselessly repeatedly, macula by become less dense, by inhomogenous distributing come to distributing equably, blow when random square (25mm×25mm) achieve 4 ～ when 6 o'clock, surface roughness of surface of boring machine workbench achieves Ra2. 5 ～ Ra3.
2 when, accuse namely thick blow level break down. Fine shave level: Boring machine workbench is fine blow in thick blow a foundation aspirant travel. Fine the task that blow basically solves exterior quality problem, contact precision, geometry precision namely (flatness is achieved 0.
01mm/500mm2) , exterior surface roughness (Ra1.
6 ～ Ra3.
2) , at the same time even give attention to two or morethings arrives form error. Fine the Dao Jikuan that blow is 6 ～ 8mm, grow 10 ～ 12mm, mark proposal uses the knife to be pushed continuously add turn round a law, “6” piece turn over “6” piece knife mark is better, blow Fonda to arrive when random 10 ～ when 12 o'clock fine blow level to accuse break down namely. Essence of life blows boring machine workbench Http://www.

Com/ phase: Essence of life is blown is to be in fine blow what undertake on the foundation, the task that essence of life blows boring machine workbench is to undertake rising blowing grinding exterior quality, form of give attention to two or morethings, check and ratify error. Essence of life is blown should grind very planar drawknife, want sharp, fall the knife should want firmly light, should avoid appearance of knife horn cut particularly, mark of drawknife of essence of life is wide 7 Mm of 5 ～ , narrower even shorter, inspect scrape plane size and change. Knife mark suggests to use left turn round a law or right turn round a law, exert oneself to do sth. when scrape appropriate is small, blow flower criterion exception. Increase every random when macula square 20 ～ when 25 bits, namely essence of life blows an end, flatness of workbench of its boring machine should is 0.
01mm/500mm2 is the following, exterior surface roughness is 0.
