目前,各工厂加工直角通槽,多采用整体三面刃铣刀。但整体三面刃铣刀重磨后,其宽度变窄,要继续保持槽宽精度,就必须换新铣刀,或多次进刀,使加工精度和生产率降低,加工费用上升。这是目前槽加工存在的问题。我厂使用宽度可调可转位硬质合金错齿三面刃铣刀来加工沟槽,既可补偿刀片磨损后的宽度尺寸的减小,又可减少铣刀宽度规格。若选择适当的切削用量,各种沟槽可一次走刀铣成,精度可达H8,光洁度可达▽6。据调查,使用该铣刀后的实际生产率约为同类焊接铣刀的1.5倍,生产费用可降低35％左右,经济效益显著。一、结构宽度可调可转位硬质合金错齿三面刃铣刀的设计,以加工一般钢材和铸铁为主,其他某些难加工材
At present, the factory processing right-angle through slot, the use of the overall three-sided cutter. However, the overall three-sided cutter after grinding, narrowing its width, to continue to maintain the slot width accuracy, you must change a new cutter, or multiple feed, the processing accuracy and lower productivity, processing costs. This is the current slot processing problems. I use the factory adjustable width adjustable carbide wrong tooth three-sided cutter to machine the groove, can compensate for the reduction of the width of the blade after the wear and tear, but also reduce the width of the cutter specifications. If you choose the appropriate amount of cutting, all kinds of grooves can be a pass milling, accuracy up to H8, finish up to ▽ 6. According to the survey, the actual productivity after using the cutter is about 1.5 times that of the same welding cutter, the production cost can be reduced by about 35%, and the economic benefit is remarkable. First, the structure width adjustable Carbide wrong tooth three-sided cutter designed to process the general steel and cast iron-based, and other difficult to process some of the material
