the introduction Kong Jia is versed in used high speed, efficient treatment uses bit under, and the MQL that is helpful for environmental protection machines means. What introduce above all is, the lengthen oily opening that can undertake to rolled steel efficient deep Kong Jia is versed in is gotten, be similar to crankshaft inclined hole to machine this kind to have the technology of deep aperture treatment to rolled steel, can saying is Kong Jia in labour allow the most tiredly. In recent years, as the development that high speed machines, the hardness of cutting tool also rises considerably, but in such deep aperture treatment, even if tall hardness broach is incidental also bits of collapse blade, platoon jams etc is the element that makes treatment not stable. Accordingly, the gun that what the manufacturer uses mostly is low feed speed is gotten, or it is to use broach of high-speed steel lengthen to undertake type of a flight of stairs is machined. Be aimed at this kind of circumstance, OSG is new the FTO-GDXL that rolled out treatment of deep to high speed aperture to have revolutionary sense, its feature and exterior show 1 times like the graph: The cutting chamfer of the exterior graph 2 FTO-GDXL of graph 1 FTO-GDXL, size of horizontal blade shape: Ø6mm, cutting material: Speed of cutting of Gao Tangang S50C: 90m/min: Feed speed: 0.

1 before horn 140 ° , feed hole is deep: Carbon steel of 6mm graph 3 FTO-GDXL machines a condition its feature is to be able to be generated petty cut bits, and have the helix chamfer of bits of can smooth platoon. Joint action will cut the appearance of helix chamfer and horizontal blade bits is mincing. And, helix chamfer has enough space to will cut bits smooth eduction. The treatment efficiency contrast of graph 4 FTO-GDXL and traditional treatment method pursues in addition, the material about cutting tool is qualitative, because the approach of broach is very long, the circumstance such as incidental collapse blade, in using pulverous high-speed steel so special be able to bear or endure the material that the advanced material of collapse caustic regards cutting tool as is qualitative. The coating surface of TiAlN and before coating photograph is compared, raised smooth sex, with benefit Yu Shunli discharges bits. The cutting function of FTO-GDXL introduces below. Head the treatment case that is high-carbon steel solely, with conventional treatment the method is compared, machine bear of efficiency, treatment, life to wait for following place to show. If the graph is shown 3 times,machine a condition. Those who need an attention is, when using this bit, feed hole is necessary. Because the cantilever of cutting tool is very long, if do not have feed hole. Of broach cut ministry branch generation to shake, the entrance diameter of aperture can greaten, of course life also can reduce place. If the treatment requirement that fits most so pursues 3, use short blade first namely model make alloy broach forcedly undertake feed hole is machined. The diameter of feed hole is broach diameter + 0.

02mm ~ 0.

1mm is the following. The dimension that horn should is equal to before or is more than broach such broach can begin to be cut from central ministry, it is life, precision or invariability had been compared no matter. The is used extensively gun in be being machined with traditional deep aperture is gotten or photograph of high-speed steel lengthen broach is compared, the treatment efficiency of FTO-GDXL is highest 6 be gun getting.

5 times, it is 15 times what high-speed steel lengthen gets. The cutting of graph 5 FTO-GDXL fights strive to pursue 5 it is to use the cutting when FTO-GDXL undertakes machining to fight strive, if plan institute is shown, the graph below the case that gives in Gao Jin is smooth, as the addition of hole depth, cutting fights force and did not increase. And platoon bits is smooth, do not have jam phenomenon. Graph 6 denotive it is feed ordinal the life when increasing. Graph the aperture when the life plan 7 FTO-GDXL below all sorts of 6 conditions is machined enlarges quantity elapse to pursue Kong Shuguang clean spends Ry[µm] aperture to enter the mouth the hole bottom between Kong Zhong the 1st aperture 5.

The hole wall that 2mm/r) graph 8 FTO-GDXL machines is bright and clean degree even if the deep aperture treatment of 20 times diameter, why planting no matter below treatment condition, treatment opening number is in 800 aperture above () of above of cutting length 97m, the efficient, long life that this is unprecedented machines case. VBM of decision criteria of cutting tool life is 0.

40µm, we can see, what undertake with FTO-GDXL is the smooth, cutting that did not shake machines a bits. When resembling undertaking with lengthen broach Kong Jia is versed in so, the verticality of aperture is a problem. To this problem, if the graph is shown 9 times, the aperture that machines with FTO-GDXL arrives from orifice the verticality of hole bottom is extremely tall. The aperture with deeper introduction machines case below, treatment material qualitative SCM415H is very easy felt, easy platoon bits jams, but get sth done without any letup of the 30 times diameter when FTO-GDXL is machined. If the graph is shown 10 times,machine a condition. Resemble the treatment condition of above. Traditional gun gets the handling time that machines an aperture to be 1 minute 30 seconds above. If use the word of FTO-GDXL,need 19 seconds only. Main shaft burden is very stable also, if the graph is shown 11 times, resemble the material of so easy cohere, cut bits very petty also. Graph the verticality dimension of the aperture that 9 treatment cross: Ø5mm, cutting material: SCM415H cutting speed: 60m/min, feed speed: 0.

3mm/r hole depth: Style of stage of D) of × of 140 Mm(28 of hole depth of 150mm blind aperture, effective treatment machines: Inorganic fetterses: Cutting of horizontal M/C BT40 is oily: Water-solubility air pressure: Dimension of 3MPa feed hole: Ø5.

Low rotate speed of ☆ of 10mm of broach of 1 hard alloy, deepness inserts feed hole, turn up is waited for to arrive after inserting appoint rotate speed resumptive treatment. Fall again after treatment for low rotate speed. The treatment condition of graph 10 SCM415H, 30 times diameter begins to introduce the treatment case of MQL now. In recent years, get attention as a result of the equipment of environmental protection problem, cutting machines the spot to reduce litter to do one's utmost, more and more favour does type treatment partly. Among them automobile manufacturing industry also pays close attention to MQL treatment very much, FTO-GDXL also can very good undertake MQL is machined. Its treatment case introduces below. In automobile manufacturing industry, the component treatment with the main engine such as lid of crankshaft, cylinder body, crock begins to use MQL treatment. This among them, the oily aperture on crankshaft is 10 ~ mostly the deep aperture treatment of 20 times diameter. If use traditional treatment method to undertake machining, life of handling time, cutting tool, stability is treatment difficulty. Because the component of above introduction machines special difficulty, what basically use so is before introductory gun is gotten and broach of high-speed steel lengthen. Qualitative like such material hardness machines a component high, hard, can undertake with FTO -GDXL type is machined working partly. It is to use FTO-GDXL below, machine case to what S50C undertakes MQL is machined. If the graph is shown 12 times,machine a condition above all. Graph 11 SCM415H cuts bits picture size: Material of Ø6mm, cutting: Speed of cutting of Gao Tangang S50C: 90m/min, cutting measures: 0.

2mm/r hole depth: 100mm via (17 × D) is mechanical: Cutting of horizontal M/C HSK63A is oily: MQL sparge gives pressure: 0.

4MPa sparge supply measures: Dimension of 50cc/h feed hole: Ø6.

The horn before 05 broach deepness of 15 ° feed hole: If the life of cutting wear cutting that the 13 S50C MQL of treatment condition graph of 6mm graph 12 S50C machines pursues 13 are shown, and broach can undertake again abrade, reuse. So again abrade function also is one of main index that decide product value. Graph 13 it is to be tasted newly, again abrade, again the comparison of the life of coating pursues. Institute of as above plan is shown, even if 100m of length of MQL treatment, cutting, still but proceed treatment, its life is first-rate. And, the course is again abrade, again after coating, still can obtain follow to taste same cutting length newly. Introduce like above place, FTO-GDXL is the high speed that can undertake tall difficulty is machined deep aperture treatment uses bit. Beyond the S50C that material of the closest, treatment introduces besides above character, SCM415H, still the material such as FC250, SCM440, SCM420H, SCr420H, SNCM439 pledges, it is very big to machining difficulty SUS420J2, 15-5PH, SKD11(had not been handled even) also can undertake 10 ~ of 30 times diameter be versed in into Kong Jia without halt. Actual treatment condition is shown 14 times like the graph. Cutting of rate of cutting of cutting material dimension measures oily FC25OØ61200 of hole depth cutting.
