经过热轧后的黄铜板,由于温度和热轧过程中各种因素的影响,在表皮上生成一层氧化皮热硬层。这种氧化皮热硬层对铜制品的压力加工质量有着一定的影响。目前国内外许多厂热轧黄铜板去除氧化皮热硬层的主要措施是用硬质合金组合盘铣刀进行铣削加工。另外,这种刀还可以用于不锈钢板、较厚的铝板生产上。为了解决国内用户生产的急需,我厂仿制了西德进口的硬质合金组合盘铣刀,曾先后制造出八组。通过几年的生产试用,其尺寸精度达到设计要求,基本上满足了用户对黄铜板生产的需要。
After hot-rolled brass plate, due to temperature and hot-rolled various factors in the process of the formation of a layer of skin on the epidermis thermal hard layer. This oxide scale hot hard layer on the quality of the pressure processing of copper products have a certain impact. At present, many domestic and foreign plant hot-rolled brass plate to remove the hot hard layer of the main measure is to use hard alloy plate cutter for milling. In addition, this knife can also be used for stainless steel, thick aluminum production. In order to solve the urgent need of domestic users, I plant imitation of West Germany imported hard alloy disc cutter, has created eight groups. After several years of production trial, its dimensional accuracy to meet the design requirements, basically meet the user needs of brass plate production.
