Pfauter SF1 Worm & Thread Milling Machine TRT#68

Description

A genuine Pfauter — from the company that invented gear hobbing

This Pfauter SF1 comes from the company founded by the man who literally invented and patented the modern gear hobbing process, in Chemnitz, Germany in 1897. Pfauter’s name became so synonymous with the process that machinists still use it informally as shorthand for gear hobbing machines generally — and the company continues today as Gleason-Pfauter, still a leader in gear manufacturing technology.

Maker: Maschinenfabrik Pfauter, Chemnitz (Germany)
Model: SF1
Type: Manual worm and thread milling machine

Overview

The Pfauter SF1 is a precision German-made worm and thread milling machine designed for producing single- or multi-start worms, lead screws and other high-accuracy threads. Its rigid construction, short gear trains and versatile head options make it suitable for both repair workshops and gear manufacturers.
