Milling cutter is the main tool of mould processing, the processing capacity accounted for about 80% to 90% of the total mold machining, thus become the development focus of mould processing tools. In this exhibition, exhibited many tool enterprises are used for mould processing complete sets of milling cutter, and the mold after machining and cutting tools are put together to show at the same time, attracted many visitors. Exhibited, for example, sandvik coromant CoroMill milling cutter series "family" of many members, many of which are used for mould processing of milling cutter.
Because of the milling cutter is one of the largest tool in machining metal removal, therefore, improve the efficiency of milling has become one of the direction of the milling tool innovation. Sandvik coromant exhibitors CoroMill 345 is a make light edge blade 45 ° Angle Lord face milling cutter, and compared with the standard of the parallel blade blade face milling cutter, can make workbench feed speed increased by three times, and get a better surface finish. Traditional equipped with repair light edge blade milling cutter is usually fine milling cutter, the cutting depth volume is small, and CoroMill 345 maximum cutting depth of the milling cutter can be up to 6 mm. In this exhibition, solid g company also introduced a similar milling cutter. Can be predicted that they are new products on display set up the big cutting depth, feed mill of new standard, will cause the resonance and follow up of the industry, to improve the enormous quantity wide flat milling quality and efficiency is of great significance.
The structure of the new promotion of a milling cutter
In this exhibition, you can see, in recent years the development of some new structure has been applied in more milling cutter products, some cutlery maker into a series to promote adopts new structure of the milling cutter products. Slopes can be feed milling cutter, for example, is the earliest for processing within the mold cavity or closed slot and development, it has the plane milling, milling, milling cavity hole and other functions, very suitable for the characteristic of mould processing process, can reduce the time of the knife. Slopes on the show, can feed milling cutter structure has been applied to the face milling cutter, end mill, the square shoulder milling cutter, circular arc Angle cutter, such as different varieties of milling cutter, make most of the varieties of cutter has the advantages of multifunction, not only for mould processing, but also bring a wide range of conventional milling greater benefits.
Similar situation also appeared in small cutting depth, feed mill, zhuzhou diamond cutting tools co., LTD., Tungaloy company have developed this kind of milling cutter series products, such as to make full use of its advantages of large feed milling efficiency. Tungaloy company even applying this concept to Turning tools, introduced a Turning X large feed tool, can to improve processing efficiency by 8 times. Zhuzhou diamond cutting tools co., LTD is a newly developed FMD03, FMD04, FMP03 series vertical cutting face milling cutter blade gravity, with LNKT series of blade is the blade Angle and the rake Angle, cutting briskly in the processing, less power consumption, machine tool cutting depth can be up to 17 mm, machining efficiency is very high.
Improve the economic benefit of the cutting tool
In order to help the tool users to overcome the difficulties brought about by the financial crisis, from the structure design of cutting tool, improve the economic benefit of the cutting tool to become one of the characteristics of the milling cutter with new product development. Is a kind of widely used approach, the design of indexable insert for double sided available, make double cutting edges. At the same time, can also by increasing the number of edges of polygonal blade to improve its economy. In this exhibition, equipped with hexagon, heptagon or octagon double-edge blade face milling cutter has become the exhibition companies promote economy a selling point, Dijet as Japan company equipped with heptagon face milling cutter blade, mitsubishi and equipped with octagon CBN inserts face milling cutter. In addition, VARGUS launch of the thread of the blade to the usual three point increased to 6, and is a double blade, the blade cost lower than doubled.
Companies display module type can be removable nipple end mill can not only shorten the tool change time, and can reduce the number of tool rod, reduce the tool cost. Research company on a vibration cutter arbor, the use of special alloy to replace the commonly used cemented carbide materials, reduce the cost of the cutter arbor.
The development of the whole hard alloy cutter
Solid carbide end mill is the mainstream of mould processing cutting tool. Can be seen from this exhibition, the main development trend for:
(1) to develop a variety of vibration milling cutter
In this exhibition, Hitachi's EPOCH MIRUS series high efficient die cutter by optimizing the design of New Guinea corn tooth shape, and the adjacent blade cutter tooth not equidistant dislocation structure, reduce the cutting force and vibration, improve the processing efficiency.
(2) development of machining of hardened steel milling cutter
This kind of milling cutter for processing material hardness range from HRC45 - HRC67, even up to HRC70. For example, can best company of the coating cemented carbide end mill (using HARDMAX coating) is suitable for the high speed machining hardness HRC45 - HRC65 steel mold.
(3) the development of the milling cutter machining difficult-to-machine materials
With the development of the aerospace industry and energy equipment manufacturing, super alloy (including high temperature alloy, titanium alloy, etc.) the rapid increase of the dosage of the machining efficiency and tool life put forward higher request, also promoted the tool supplier's new product research and development work. Mitsubishi company launched CoolStar series, for example, solid carbide end mill, a specially designed chip groove shape to improve the chip removal effect, and in each of the chip groove set up multiple internal cooling hole, improves the cooling effect, coupled with good abrasion resistance and high toughness is adopted base material, which can realize the efficient of super alloy material processing, and prolong the tool life. OSG exhibited at the company for the processing of composite materials research and development of aviation industry vertical milling cutter, the milling cutter has a special channel, in the multilayer composite sheet machining, can avoid to produce delamination and burr formation.
(4) the development of processing the graphite and aluminum alloy milling cutter
Such tools used diamond or class coating, can provide efficient processing graphite electrode and aluminum alloy with powerful technical support. OSK company of aluminum alloy, for example, rough machining cutter rake face with oblique points crumbs slot, can make cutting more lighthearted, and prevent the chip bonding, make the knives' service life is longer.
Cutting tool application guide to action
It is worth mentioning that in this exhibition, sandvik coromant company visitors to distribute the booklet "milling application guide", the content including the selection of milling cutter, milling parameter Settings, the right tool path and the implementation plan, etc. The popularization application of nc machine tool, the traditional milling method cannot meet the requirements of CNC milling, greatly restricted the give full play to the performance of nc machine tools. This comprehensively and systematically introduces the modern new milling technology and practical application of knowledge brochure to promote the progress of modern milling technology and the popularization application, improve the milling technology and social and economic benefits has important value, will have far-reaching influence. On display in the show at the same time the technical guide manual including turning, milling, drilling, boring and handle, etc, this paper introduces the application of new technology of modern tools. The value of these technical data for the tool users is much more than a new tool, has become one of the highlights of the exhibition, the cutting tool users should pay attention to.
