As a product of the contingency challenge, Sandvik Coromant has developed a new generation of P25 grade GC4225 (Breakthrough No. 1) (Figure 3), which is an upgraded version of the GC4025 grade and is a powerful addition. Versatile and versatile solution. Depending on its optimized performance and high reliability, it is possible to increase production efficiency by applying higher cutting parameters and to adapt to changes in workpiece materials and increasingly demanding operating requirements.

Referring to the importance of dealing with unpredictable blade wear, try the processing of aircraft landing gear (alloy steel). The typical procedure is to perform two semi-finishings (up to 8 mm) and then perform a finishing (cutting depth of 1 mm) to allow for machining allowance for the next process. The insert must meet the exacting requirements of both processes in order to maintain good chip control and constant tool life in order to complete the entire cutting process.

First, the GC4225 grade improves the shape of the P25 insert and broadens the range of applications for ordinary steel turning inserts. Secondly, both blade toughness and wear resistance are improved, providing the potential for a variety of demanding processes. Third, by continuously reducing the types of harmful wear, tool life has doubled compared to older models. And because the wear can be predicted more accurately to avoid destructive wear, the overall cost of the steel turning process can be reduced, which is quite attractive to the shop. Fourth, it has the predictability of tool life and further improves the adhesion of the coating, which significantly improves the edge safety of the blade. Fifth, improve heat resistance and achieve better durability.

As for the potential of the new grades for a variety of demanding processes, the machining of automotive crankshafts, for example, involves the turning of steel forgings and the demanding intermittent cutting. This should be classified as a P25 application range and is usually machined with a more tough P35 grade blade with a tool life of 44 parts per cutting edge. The actual test result is: the old P25 grade has only the tool life of 14 parts, while the GC4225 grade has the tool life of 41 parts, which has approached the wear level of the P35 grade. It can also be verified that Sandvik Coromant has the strength to cope with challenges as a well-known brand in the tool field.

Fast metal cutting ISCAR tool new

ISCAR's new 2006 product covers milling, turning, hole machining, and multi-tools as an important complement to fast metal cutting (FMR). This confirms ISCAR's philosophy of encouraging users to access the latest cutting technology and upgrading their tools and production processes accordingly to achieve better performance and features in cutting, just as computer users are constantly updating their hardware and software.

In 2005 and 2006, the company implemented a comprehensive upgrade of the tools, improved penetration into the coating, cemented carbide substrate, cutting edge geometry, product line and other aspects. First, the alloy grades were upgraded: AL-TEC (PVD coating) is mainly used to process ductile iron; α-TEC (CVD coating) is the main processing of gray cast iron; DO-TEC (CVD+PVD composite coating, more strength) High) brings about a revolution in cast iron processing. Moreover, thanks to the successful application of state-of-the-art alloy grades for more efficient and economical machining, the number of cutting edges per blade design is greater.

In addition, “mini design” is another concept of new product development. For example, a mini-head milling cutter with a high feed rate is designed using a mini butterfly milling cutter as shown in FIG. Thanks to the small size of the blade and its vertical structure design, more milling cutter outer diameter can be designed compared to conventional milling cutters.

UPGRADE's HELIOCTOFEED octagonal UFO cutter combines the advantages of a three-blade UFO cutter and an octagonal blade, allowing more inserts per blade to be used for efficient machining; UFO King Kong has a large arc-shaped cutter head. It can realize high-speed feed in small depth of cut; finish the wave-edge end mill, and realize the single-hard alloy end mill to complete rough finishing at the same time. When this advantage is applied to slot milling, 90° shoulder milling, and pocket milling, high quality surfaces can be obtained with rough machining parameters.
