镗杆上装浮动镗刀块位置的尺寸和形位公差精度要求很高。在使用过程中,由于镗杆磨损影响了工件质量。而制造新镗杆工艺复杂,费用大。我们在实践中,摸索出了镗杆粘结修复的方法,效果良好,现介绍如下: 一、修复方法将镗杆刀槽宽度尺寸的两侧,在插床上单面插去2～2.5mm,四角插成燕尾形状如图1所示。然后,测量宽度尺寸及对称超差数值,每面留精加工量0.15～0.2mm。计算出垫板的厚度,见图2。垫板长度和斜面 Boring bar on the floating boring block location of the size and shape tolerance requirements of high precision. In use, due to the boring bar wear and tear affect the quality of the workpiece. The manufacture of new boring bar technology complex, costly. In practice, we found out the boring bar bonding repair method, the effect is good, are described as follows: First, the repair method will be boring bar width on both sides of the groove, inserted in the plug on one side of 2 ~ 2.5mm, Into a dovetail shape four corners as shown in Figure 1. Then, measure the width size and symmetrical tolerance values, leaving a finishing allowance of 0.15 ~ 0.2mm on each side. Calculate the thickness of the pad, see Figure 2. Pad length and bevel
