Landis Threading Machine By Michael Feinstein
It was 1903 when Landis began providing machines and accessories for high volume thread cutting and rolling applications. Although new machines are no longer available, the used machines remain the finest in the threading industry today. Today Landis provides solutions for both cutting and rolling with die heads, taps, reamers, replacement dies, chaser holders, carriage grips, cutter discs and other ancillary items. At Universal Metalworking Equipment, we specialize in cut threaders that perform threading on bolts, pipe, and rebar, nipples, API applications as well as large diameter threaders for NPT and NPS pipe. The bolt threaders are capable of UN threading, NPT, ACME, API, Whitworth, metric and special applications. As you can see, Landis machines have great versatility in size range and thread form. Landis is still in business today providing tooling and repair parts are readily available. The standard thread cutters are also easily adapted to roll threading. What may be helpful is what to look for when you are inspecting a machine for purchase. It is always best if you can make an inspection under power. This is your real opportunity to examine the machine and determine its ability to do the job it is intended for: Head Stock: 1) 2) 3) 4)
