Kennajin belongs to spaceflight industry CFRP broach of special and new-style SPF

The CFRP(carbon fiber with light-duty, good performance enhances high end polymer) material is in aviation industry more and more be welcomed. But the problem is this kind of data appears easily in treatment material is statified phenomenon, it is especially in bore treatment. Kennajin belongs to what be weighed to be emerge as the times require of new-style SPF broach. This kind of new-style SPF broach is in life of its cutting tool (be PCD broach at least 2 times) limits is used inside the aperture with can be obtained better machines quality, the charge that still can make machine every aperture is reduced at least 50% . the application with respect to CFRP composite material, press weight plan to occupy 6 ～ in the aircraft at present 7% , and weight plan is pressed to predict to be able to achieve 40 ～ in prospective aircraft 50% . Machine with costly PCD broach when us multilayer when carbon fiber composite material, because greater cutting power makes material easily statified, and still can lower cutting tool life, make productivity low. Kennajin belongs to the broach base material of new-style SPF to use hard metal, prolonged the life of cutting tool via parameter of optimized cutting tool geometry and coating, reduced cutting force considerably, decreased thereby statified (if do not have,eliminate completely statified) . Smooth CVD is multilayer diamond coating makes the cutting tool of SPF broach had good wearability and lesser coefficient of friction to prolong cutting tool life thereby, improved performance of the flow that cut bits. Get a needle specially to repair the precision in grinding a technology to raise cutting tool to be opposite and reduced axial force, made sure aperture machines quality. Is the Kong Jia that Kennajin belongs to versed in product manager Marcelo Campos says: ? The CFRP that the SPF broach that have a nightmare of Xing of Sui of pain or numbness caused by cold circles Kennajin belongs to scull? machines extremely hard in treatment can machine 300 aperture when material, 1000 aperture can be machined when the CFRP data that processes other category and do not appear statified " . New-style SPF broach has 24 kinds of different standard diameters, from 3.

20mm(0.

1719 inches) to 6.

50mm(0.

5010 inches of) , the length of cutting tool is a standard 3 times and 5 times Yu Dao provides a diameter. But Campos expresses: " we still can ask to offer a solution according to the client, according to user need we can be produced for example length the 7 times cutting tool at cutting tool diameter " .
