Come with blowing era to grind attain perfect

3 to 3mm between, precision is DIN mark the spare parts such as axis of the oil hard gear of 7 class of 6 ～ , tine and worm, the finish machining craft of domestic tradition basically is roll flute and scrape of hard tooth flank (blow tooth namely) two kinds. But the limitation that goes up as a result of hob material, blow tine to be not used by people place normally. In recent years, improve of the structure ceaselessly as the machine tool, machine tool and workpiece clamping apparatus rise rigidly, the progress of cutting tool material, especially the development of coating technology, make the treatment quality that blows tooth and stability rise increasingly, craft matures popularly in making precision work of hard gear of small modulus oil gradually, a lot of enterprises of foreign already phase-in blows tine to replace roll flute to regard finish machining as the method. The finish machining of axis of oil hard gear, tine uses gear of small modulus of precision work of the craft that blow tooth, precision can reach level of DIN mark 6~7, quality of exterior surface roughness is high, and stability is very tall also. On the foundation that assures product quality, to roll flute, the advantage of the craft that blow tooth has the following: ◆ efficiency is tall machine to the hard tooth flank of small modulus gear, if use technology of roll flute machine, because work is very little, treatment place space is limited, roll flute machine gets on emery wheel diameter very big limitation (normally roll flute is in with emery wheel diameter 150mm above) , can use only shape an emery wheel (the diameter can accomplish 60mm) undertake chasing aging machining to gear, its treatment metre is very accordingly slow, efficiency is very low. And the technology that blow tooth has on gear-hobbing machine, because use the hob of lesser external diameter (be like diametical 24mm, the hob of 32mm) , treatment metre is very consequently fast, efficiency is very tall. Generally speaking, its machine metre to shape to use merely an emery wheel of metre of the grinding that chase tine 1/4 to 1/2, namely its produce efficiency to shape than using the grinding that chase tine wants an emery wheel normally tall 2 ～ 4 times. ◆ cost is low it is with the gear-hobbing machine of Koepfer exemple, deploy workpiece to blow tine craft place to need cutting tool, clamping apparatus and accessory, total prices is 35~45 only 10 thousand euro; And fall in the condition that provides treatment to use emery wheel, clamping apparatus and accessory likewise, the price that imports roll flute machine is controlled in 1 million euro normally. If the element plus treatment efficiency, the yield that uses the craft that blow tooth to be able to be achieved to a gear-hobbing machine can, the likelihood needs to purchase 2 ～ ability of machine of 3 roll flute comes true, the investment cost that consequently place of two kinds of different technology requires differred 4 ～ 6 times. Additional, considering cover an area of area, the sources of energy to use up, the operation staff that needs to deploy, equipment safeguards the element that reachs spare parts of machine parts or tools kept in reserve to prepare to wait for square field surface, to roll flute craft, because blow tine craft place to require facility amount little, its cost a lot of lower. ◆ equipment versatility is tall normally, the treatment of high accuracy gear is included commonly boil beforehand (before quenching namely soft boil) with finish machining (after quenching blow tine or roll flute) two working procedure. For not big to production lot company, can use undertake on same table gear-hobbing machine soft boil and blow tooth, and need not buy roll flute machine additionally; Below large quantities of circumstances that estimate production, boil beforehand and blow tine to need possibly to part to be machined on different machine tool. But when equipment type selecting, can consider to use same kind gear-hobbing machine undertakes respectively soft boil and blow tooth. Such, safeguard in the machine tool, spare parts and fragile on preparation all OK and general; When soft billow knife needs new blade to grind with the hob that blow tooth, also can use same hob blade to grind machine undertake repairing grinding, of course, two kinds of hob can be in Baerchasi (Balzers) the company has cutting tool again coating. The finish machining of hard worm of Nextpage temper by dipping in water is before this, modulus is 0.

3 still cannot finish all outline figure in same table gear-hobbing machine to the worm treatment between 3 Mm. However Koepfer company depends on new research and development roll milling head and corresponding software successfully will soft mill (axial, radial and tangential milling) beautiful couple is finished in a gear-hobbing machine with good treatment, and will machine quality rose multiple. 3 years ago, koepfer company was configured on the gear-hobbing machine that in craft reliable, technology matures those who be used at machining worm is newest and general but deflection rolls milling head, came true to be mixed with worm of gear-hobbing machine treatment undertake blowing tooth forcedly. This are general but deflection rolls milling head function powerful, the structure is compact, the milling of the gear hobbing that is columnar gear only and only head and bull worm is machined and design. because the structure is compact, roll milling head to be able to swing so the outline that worm machines below rear push frame. Can say, kopefer company created brand-new applied field for gear-hobbing machine, extended the applied range of gear-hobbing machine considerably. The new drive skill that Kopefer company deploys, the acme nicety that innovation went to be able to machine ability to achieve through grinding only before and outstanding character. Well-known the worm actuating device that takes crossed across axis so far is produced through dipping process commonly. Although use traditional gear-hobbing machine to also can machine worm, but cannot satisfy high accuracy. And the spare parts of aerospace domain, if be used at adjusting a plane to land the actuating device of flap, the precision that must satisfy DIN6~7 class asks. The high nicety sex that machines as a result of Kopefer company gear-hobbing machine, add can come true tangential milling, can configure special cutting tool; Still have the software that is this research and development only finally, achieved the precision requirement above completely. When use Koepfer gear-hobbing machine machines worm, can have soft mill to worm first, undertake blowing tooth forcedly inside same machine tool next, hard even gear hobbing with working procedure of dispense with grinding. Achieve workpiece sclerosis processing HRC54 first that is to say, undertake hard scrape next, can reach optimal mass so. The gear-hobbing machine of the characteristic of Koepfer gear-hobbing machine and advantage Kopfer company used enclosed frame structure as always, use technological sophistication long-tested, by advanced polyester material (common weighs a scagliola) mould and become lathe bed, the machine tool configured axis of at least 8 CNC (among them one is used at wearing manipulator high) . And " U " the vertical machine tool of shape structure is different, this kind of enclosed structure getting power avoided main shaft of dynamical rear push frame to be achieved in clamping force and cutting force the biggest when of generation bend. The BWO that the machine tool configures controls a system, sound a bit may unfamiliar still, mix for certain however by the expert praise highly. Control system belt feels type to dominate screen, have inside the program memory that the capacity of buy is 1 million. Use interface of conversational form process designing by the software of Koepfer company research and development, the operation is simple, even if general technology personnel also can master process designing skill very quickly. The main good point of Koepfer gear-hobbing machine: The machine tool was configured general but deflection rolls milling head, applied field is wide. The function is powerful, can complete the treatment of different outline and different technology: Be like tangential boil / milling, radial boils / milling, soft rough machining, flexible precision work and hard precision work (scrape or boil forcedly) etc. Treatment precision is tall, treatment quality stability is tall. The machine tool is flexible big, can need completely to configure workpiece to carry a system automatically according to the user. Can ground of without striking a blowing is compositive arrive inside manufacturing unit (like gear hobbing, clean, measure, place workpiece) without attaint sex ground next. The most important is, when using Koepfer gear-hobbing machine to machine axis of gear, tine or worm, can blow the perfect combination of tine again soft treatment, forcedly first in the implementation on a machine tool, it is the person that use to save cost greatly, can say the optimal option that is an user consequently.
