مجموعة تحويل بوصة 20TPI لأجزاء مسمار التغذية، ماكنة مخططة صغرى

Installing these on my mini lathe was straightforward and the cross slide now moves with satisfying precision. The 20 TPI really makes fine adjustments easy and I can see the 0.050" advance per turn in my threading work.

The math works out perfectly—0.050" per rotation is exactly what I needed for dialing in my cuts, and now I can sneak up on a dimension without guessing. The thread pitch conversion feels smooth on both the cross slide and compound, no binding or slop.

Installing these was straightforward, and the difference is immediate—that 0.050" per rotation makes dialing in precise cuts feel way more intuitive than the stock threading. My cross slide now moves exactly as expected every time, no more guessing.
