From complicated medical and industrial products, Judson Smith will provide precise quality and job flexibility. Three shifts of operation result in unmatched capacity and rapid turn-around!
Laser marking is a computer-driven, environmentally friendly alternative to silk screening, pad printing, stamping, mechanical engraving, chemical etching, and many other costly, lower quality processes. Our high-speed non-contact process provides superior quality, permanence and design flexibility. Laser marking can achieve accuracy in small detail engraving unmatched by any other engraving method.
From ten to ten thousand, precision computer control means that your last production piece will look as good as the first!
Judson Smith offers the latest technology in fiber optic lasers to provide customers with a broad array of tools to meet their application challenges. Whether cutting, welding or marking, our in-house expertise provides customers with a wide range of manufacturing technologies.
Due to their short wave-length, Judson's laser technology offers extremely precise cutting. Our four axis machines are capable of cutting multiple geometric and single wall features. The kerf width allows cutting diameters to be very small and accurate (.002"). The limited "heat affected zone" is essential when cutting thin wall metal tubing to eliminate any mechanical or thermal distortion. Contact us for more information on our laser fabricating capabilities.
Precision laser welding is a process of joining similar or dissimilar metals together without using additional filler materials. Our beam quality allows us to control the energy being delivered, resulting in minimal heat input, therefore avoiding any mechanical or thermal distortion.
A single laser pulse or a series of pulses causes the materials to heat up at the joining area until melting point is reached...almost instantly; a clean and uniform welding path is created.
Judson Smith also brings 50+ years of tube fabrication experience to solve our customers tube design and manufacturing challenges. Judson Smith not only fabricates tubes using standard “off the shelf” machines and equipment but also has the unique ability to design and build custom equipment to automate higher volume production. This capability minimizes the processing steps required to manufacture complicated tubing shapes and features and delivers significant per unit cost savings to our customers.

Expansion or reduction of the tube diameter is frequently employed to maintain a good balance between strength and length of a component.
Transitions are smooth and free of the interference that results from the use of adapter and coupling devices. Generally, the wall thickness of the small diameter section will be slightly heavier than the larger diameter.
To avoid added operations, the ratio of the Small O.D. / Large O.D. should be .7 or greater. However, by using multiple operations, the ratio can be exceeded.
| Feature | Limits | Tol. (IN.) |
| Reduced length | --- | + .010 |
| Transition angle | 11' to 15' | |
| Overall length | --- | + .010 |
The possible configurations of bent tubes are virtually unlimited. From the manufacturing point of view, the greater the bend radius to O.D. relationship becomes, the easier it is to produce a component with minimum distortion (ovality) in the bend area. This is also true relative to wall thickness, in that the heavier wall products generally bend better.
| Feature | Limits | Tol. (IN.) |
| Bend radius | 2 x O.D. (ref. min.) | + .05 R |
| Distance "L" | 2 x O.D. (min.) | + .005 |
| Bend angle | --- | + 1 deg. |
| Straight length | --- | + .010 |
One or more grooves may be employed to increase turbulence of a fluid passing through the tube, thereby improving thermal transfer. The groove may also be used to locate other components inside the tube or provide a means for retention of subsequent assemblies. Due to work hardening in the groove area, ductile materials and tempers should be specified.
| Feature | Limits | Tol. (IN.) |
| O.D. | 187" max | std. |
| Wal | 5% to 15% of O.D. | std. |
| Groove width | None | --- |
| Groove depth | .15 x O.D. (max) | --- |
| Groove location | 7 x O.D. (min) | --- |
Beading can serve to provide a seat or stop on the outside of the tubular component. If the bead diameter is only slightly larger than the original tube diameter, a friction fit can be developed between the bead and the mating part. Since the bead is essentially free form, the shape is not easily controlled.
Subsequent to beading, thermal treatment may be required to relieve stresses and improve mechanical integrity.
| Feature | Limits | Tol. (IN.) |
| Bead dia. (max) | 1.4 x O.D. | + .002 |
| Bead location | .050" (min) | + .003 |
| Bead width | 2 x wall (min.) | + .003 |
| Overall length | --- | + .003 |
Flared ends are commonly used as sealing surfaces; 37° flares, also known as AN fittings, required a backup sleeve and are normally used in high pressure applications.
45° flares, also known as SAE fittings, are commonly used throughout the automotive industry.
90° flares, also known as TRI-CLAPMS fittings, require a gasket and are widely used in sanitary applications where ease of disassembly is required for regular cleaning operations.
| Feature | Limits | Tol. (IN.) |
| Flare diameter | 1.4 x O.D. | + .004 |
| Radius under head | .050" (min.) | + .002 |
| Transition radius | Under head rad. + wall | --- |
| Overall length | --- | + .003 |
Notches in the tube wall may allow internal components to be viewed directly for positioning or assembly operations.
If the notch width exceeds I.D. minus 4 x wall thickness, the notching tool action must be tangential, rather than radial, to keep distortion of the tube to a minimum.
In parts under 2" in length, Notching can be combined with tube cutting, for cost savings.
| Feature | Limits | Tol. (IN.) |
| Location | 2 x wall (min.) | + .003 |
| Notch length | 2 x wall or .010" (min.) | + .001 |
| Notch width (min.) | 2 x wall or .015" (min.) | + .002 |
| Notch burrs | 0 -.002" (max.) | --- |
The Lanced tab is appropriate as a stop for I.D. assemblies or to create friction between mating parts. Since creation of the tab feature does not generate any chips, it is one of the easier fabrications to produce.
| Feature | Limits | Tol. (IN.) |
