Traditional ISO in turning technology innovation and as important as high-tech alternatives
Are as many lectures, seminars and specialist publications such as the considerable interest in turning high hardness materials, super finishing, dry and high-speed turning of the class of advanced technology and traditional techniques in the development of ISO Turning seem is stagnant. But the reality is far from it. Due to the direction of turning over such as this technology is usually more impressive increase in productivity and lowering costs through non-traditional alternatives available, but usually cost much lower starting point. Same level of research and development of new alloy material makes hard materials such as ISO Turning and turning the line between precision seems blurred. With such as the TP1000 and TP2000 like the new carbide grade material, for turning us away from solving the traditional ISO Dilemma – cutting tools is the key but they spend so much money – further.
In engineering everything around to improve productivity and reduce costs. "Productivity" is used in a given period of time the existing production facilities, production quantity of qualified products. The total cost of access to these products is material cost, tool cost, machine cost, wage expenditure plus the cooling, security, infrastructure and so the total overhead costs.
If we look at tools, then improving quality and cutting parameters to provide more opportunities to increase productivity. Through is lower with the appropriate tools and cutting parameters to reduce the cost to extend the tool life are other possible factors. Although the proportion of the total cost tool costs less, in any case to increase the total cost for the tool life have a positive impact. Cutting parameters for different situations: nominal increase of 20% will lead to significantly reduced production costs (for example 10-15%) but significant increase in productivity. If any event we were to increase cutting speed, tool life decreases and then we need more tools to produce the same amount of product. In order to ease the procurement staff (procurement budget) and the production manager (productivity) conflict of interest between each other, the next thing to do is to develop more advanced tools and cutting materials.
Figure 1: TP1000 and TP2000 ISO turning in the formation of the second wave of optimization (to reduce costs and improve productivity) basis. Optimization depend on the following three aspects: good tools, the right cutting parameters, good knowledge of processing technology.
Such as high-cutter TP1000 and TP2000 Xiangshan a new generation of hard alloy materials such levels play a major role. Now not only improve the cutting parameters was extended tool life is possible.
For existing comparative test cases show that – due to the use of the TP1000 and TP2000 at least 30% increase in productivity and cost reduction while at least 20%.
Traditional turning Despite turning as hard (sometimes also called PCBN turning, as is usually the best cutting material PCBN), dry turning (or minimum quantity lubrication turning) and high-speed turning the arrival of new technologies, in most engineering companies turning Technology continues to be called traditional. For example, experiment with increasing milling method using a higher cutting speed in turning in only bits and pieces to use. That is partly because the development of the so-called ISO Turning certainly not standing still. Advantage of these new developments in the absence of high initial cost (without the need for new tools or new facilities) does soon get under the premise of improving productivity and reducing costs. We will simply give two examples.
Secolor blade selection system Figure 2: Secolor system helps clear understanding of the circumstances in which a particular blade is the best option. All relevant information (ISO and Secolor) were high in the mountains gives the box blade.
Let us return to the early 90's when the high mountain development Secolor system, the number of their ideas into the huge variety of carbide blades, because the user does not light the election almost tell what type of blade. Since then this concept has been further deepened, and also mimic other tool manufacturers.
When it comes to the establishment of carbide material grades and chip-breaker may take the form of applications, Secolor classification model formed to resolve the existing ISO standard ambiguous answer. Conditions through the use of options can be determined what kind of blade. Great scope for the technical point of view, is to choose the most appropriate blade to. Test series of decisions which the blade and the cutting parameters is the most satisfactory. An important evaluation criterion or blade tool life. This treatment may result in a large number of blades you hold in inventory – for each condition is the most suitable.
The other hand, if it involves many small series, you will try to use a limited kind of blade to cover the entire scope of use. Often do not have time for the test series. Further, you have to accept the best blade technology in each application can not be used inside. So evaluation criteria are: inventory and chip control.
Turning for a given application system you can easily use Secolor, systematic and quickly select an appropriate blade (in a good technical performance and have wide application best balance between the two) . This is done by using the three basic types of materials (carbon steel, stainless steel and cast iron) and three processing conditions (finishing, semi-finishing and roughing) matrix composed achieved. This basic application nine years of each of the recommended therefore essential to define a blade. Then in the second stage, this choice was further optimized, carbide material level and chip-breaking groove, both have been taken into account the. According to Secolor system feasible blade actually marked the blade on the box. Blade on the packaging that the scope of the application (in the matrix composed of nine square miles) and the basic cutting parameters
