Model 301SP Tube and Microfitting Squaring Machine

The Model 301SP was designed specifically as a tube squarer for autogenous welding applications where microfitting, tube assemblies, or the gripping of short perch length tubing is required with maximum portability. Now, you can do straight tube and fittings with one machine. A design extension of our field proven Model 301, our new "quick collet" provides positive grip with as little as 3/16" straight length. The Model 301SP's cutting head accepts the full range of typical 301 style squaring bits. Cleanroom safe, portable or bench mounted, this machine's variable speed, high torque motor delivers excellent finished on all types of materials and exotic alloys without damaging electropolished surfaces. The unit also features excellent visibility and a micrometer type feed indicator insures precise lengths.

The compact and lightweight Model 301 SP features easy set-up and operation and utilizes a precision OD saddle clamp system which securely holds and rounds the tubing for squaring. Positive clamping of the standard saddles is accomplished with as little as .60" (15.2mm) of straight tubing and the short perch saddles require .190" (4.8mm).

Another important feature of the 301 SP is the decreasing rate cam feed which moves the bit forward quickly at the beginning of the feed action and then progressively slower as the tube is engaged, producing up to .200" overall movement. This provides excellent tactile feedback allowing higher precision and more intuitive operation. No tools are required for the operation cycle, and an air clamping system is available for high production uses. If you like our Model 301, you'll love our new 301SP!
