过去我厂铰刀消耗量很大,一把铰刀累积切削孔深在3米左右就因达到磨损标准(一般约比被加工孔公差下限小0.005毫米)而报废了。为了延长它的寿命,可以应用挤压刀齿的方法,恢复刀具的尺寸,使废铰刀复活。具体方法为:用一把废硬质合金车刀(如图1),按图2所示方法对刀齿施加压力。操作时,为了方便起见,可先把铰刀放在木板 In the past I reamers consume a lot of reamer, a reamer cutting depth of about 3 meters because of wear and tear to meet the standard (usually about 0.005 mm smaller hole diameter tolerance) and scrapped. In order to extend its life, you can use extrusion knife teeth method to restore the size of the tool to rejuvenate the waste reamer. The specific method is: with a waste carbide lathe (Figure 1), according to the method shown in Figure 2 to exert pressure on the knife. Operation, for the sake of convenience, the first reamer on the board
