NEW Spline Rolling/Cold Forming Tools & Regrind
You want to conserve capital and reduce inventory, avoid production downtime, Meet production requirements all with fewer personnel.
Spline rolling is the fastest and most economical method of producing involute toothed forms. Many different types of splines, threads, grooves and serrated forms can be rolled- Individually or in combination within 3-7 seconds
The Cold Forming process is inherently accurate, with surface finishes of 3-6 micro-inches obtainable. Cold Forming is best suited for long productions runs or intermittent runs of a variety of parts.
· Save Material
In using smaller-diameter shafts. Cold Forming forms teeth by displacing metal- the outside diameter actually "grows" during forming. You can eliminate expensive chip production.
· Stronger Shafts
Result from greater density of grain structure and reduced stress concentration. Fatigue failure is minimized, and in many cases torque load ratings are significantly increased. Tooth strength and shaft life are greatly improved, with 13-35% higher load carrying capacity over cut teeth.
· Smooth Surface Finishes
Within 3-6 micro-inches have been obtained with Cold Forming- thus the original fit with mating parts lasts much longer, reducing wear and minimizing backlash.
In addition to the cost and improved product advantage offered by Spline Rolling, is another important considerate—design flexibility. Helical, Straight, Tapered Splines, and Serrations are some of the methods produced by the Cold Forming process in a variety of metals. Some of the designs call for the spline section to be rolled up to a shaft shoulder—there is no longer a need for a tool clearance recess.
Fine pitch standard splines—formed by this method—deliver minimum torque, are easy to assemble, and permit savings in material. Spline Rolling produced splines, may be heat-treated in the same manner as other similar parts.
This is also a "chip-less" operation.
