8mm watch maker lathe test

我花了两个多月时间打磨 才把这破旧的车床同心度基本解决 目前我只有0.4毫米的钻头 等我买到更小的 在做测试 看看最小能用到多小的

What were you testing for? To see if it would drill a hole?

concentricity test

[@martinlouden9005]

That's really rather sexy!

[@Wilett614]

This "test" says Nothing about concentricity . Only alignment of tailstock center to headstock . Any machinist will tell you the same thing lol

😁

[@bd5qce]

是的 我说的不对 应该说我把主轴与尾座对齐了 谢谢指正
