Sunnen and ANS Collaborate on Friction and Wear Reduction Technology
Sunnen Products Co. (St. Louis, Missouri)
Triboconditioning is a combined mechano-chemical surface treatment process which uses a machining procedure to level off surface peaks and apply a friction- and wear-reducing compound to the component surface. Unlike spray coatings, the compound becomes an integrated part of the component structure at a nano level. The process is mechanically simple and can be performed with Sunnen precision honing equipment.
Key applications include automotive engine components such as valve train parts, cylinder liners, crankshafts and connecting rods as well as industrial applications such as hydraulic motors, rock drills, pumps, chains, gears and compressors.
A laser scanning system helps this shop capture the free-form surfaces on a hand-sculpted original. The resulting digitized models are the basis for CAM applications such as programming a CNC machining center.
Laser scanning technology enables this automotive aftermarket company to design and machine custom sets of pistons in short order.
To produce high-precision ring gears in low- to mid-volumes, an emerging option is the use of five-axis machining centers. Mitsui Seiki CNC vertical and horizontal machining centers are being used in this application.
