Comparison and analysis of the machining performance of the c

Comparison and analysis of the machining performance of the ceramic end milling cutter In order to evaluate wear behavior of cutting tools, the maximum width of side wear area VBmax is usually used. The marginal quality of workpiece can also be evaluated as the wear standard for CFRP material which tends to be layered and worn. I...

Development of tool geometry

Significant differences between the specifications of the grinding wheels can also be observed on the rake face. Although the feed rates between VF = 10 mm / min and 50 mm / min are very small, the difference in the surface quality between the wheel specifications is significant for the feed speed VF = 90 mm / min. At this point ...

Development and application of ceramic end mills

The cutting materials used in CFRP processing must meet the high wear resistance requirements, because the two phase composite structure composed of fiber and CFRP with different properties is mainly accompanied by this wear mechanism. Therefore, PCD and diamond coated carbide tools are widely used, because they show proper perfo...

Experimental device

Cemented carbide is widely used in cutting tool industry, and because of the brittleness of hard material, super abrasive wheel is needed. In many cases, the use of resin bonded grinding wheels, though the material removal rate Qw is limited, can achieve good surface and tip quality. In the past few years, new hybrid bonding spec...

Optimization of the flute grinding process

As the tool grinding process has a verifiable influence on the machining behavior of cutting tools several investigations on the optimization of the flute grinding process of end mills were conducted. Therefore grinding tests with innovative grinding wheel specifications were carried out and the work result was evaluated in terms...

The superior properties of CFRPs on the other side pose a gre

The superior properties of CFRPs on the other side pose a great challenge for tool manufacturers. As the characteristics of CFRP materials can vary widely due to different compositions of e.g. fibre types, diameters, lengths andorientations as well as the synthetic matrix specification, they show also a diverse behavior during ma...

MIlling application in aerospace industry

In the last few decades, the aerospace industry has seen a good example of the replacement of existing materials and still in progress. A large part of the modern aircraft is made up of innovative lightweight materials such as carbon fiber reinforced plastics (CFRP) and aluminum alloys. Recently, the auto industry is also trying ...

The extensive use of light building materials in the aviation

The extensive use of light building materials in the aviation industry is a huge challenge for tool makers. Carbon fiber reinforced plastics (CFRP) and other materials are difficult to process. Therefore, cutting tools and requirements for macroscopical and micro design are very high. In this paper, two methods to improve the CFR...

Milling cutters and their uses

Modern CNC milling centers can use various tools to make machine operators familiar with different types of milling cutters and how to use them in daily milling. The purpose of this article is to help customers identify different types of milling cutters and their uses. Introduce The rotary multi edge milling cutter is used to pr...

The choice of drill manufacturing

Because this is a kind of optimization of nanostructures, can make the hardness, toughness and resistance of residual stress in balance, therefore, in all kinds of drilling applications, from the companys AlTiN coating is a generic solution, it is a universal coating solution. Do you need to drill steel, stainless steel or cast i...
