拖拉机、柴油机等很多零件都需要达到▽8或▽9的光洁度,用车削一般不易达到。但只要自制一个简易磨具,就可在车床上利用纵向自动走刀进行磨削。若操纵得当,光洁度可达▽10,现介绍如下: 一、磨具的制造和安装 1.按图1车制油石套简一个。 2.选用圆柱油石两条。规格:直径12毫米、长度100毫米,粗细粒度各一条(粗的用150#～220#为宜,细的以M20～M5为宜)。 3.选用弹簧一根。规格:外径12毫米、 Tractors, diesel engines and many other parts are required to achieve ▽ 8 or ▽ 9 finish, with turning generally difficult to achieve. But as long as homemade a simple abrasive, you can use the vertical lathe on the automatic grinding tool. If properly handled, the finish up to ▽ 10, are introduced as follows: First, the manufacture and installation of abrasive 1. According to Figure 1 car oil stone set Jane one. 2. Use two cylindrical stone. Specifications: Diameter 12 mm, length 100 mm, the size of each of a coarse (with 150 # ~ 220 # is appropriate, fine M20 ~ M5 is appropriate). 3. Choose a spring. Specifications: 12 mm OD,
