Aerospace-Machining of aluminum alloy gearbox housing
● Originally used cemented carbide forming tools for cutting. The main reasons for tool scrapping are sticky chips, tool tip wear, poor surface roughness, and tool marks. The machining dimensional accuracy is poor and unstable. Products need to be fully inspected before they can be delivered. The bearing hole needs to be bored to meet the accuracy requirements. low efficiency.
● After using More Super Hard PCD forming tools, PCD tools have excellent wear resistance, high surface finish and dimensional stability, tool life is improved, and cutting efficiency is doubled. PCD tool has high dimensional stability and dimensional accuracy is as high as 0.003. Save a lot of processing man-hours.
