Bushing Seal

At Tychon, Inc., we machined the bushing seal highlighted here for a client in the amusement park industry. This project came to us with very specific requirements for a 6-10 micro finish. To attain the 6-10 micro finish after heat treating to 50 HRc, we used a machining process called hard turning. Hard turning allowed us to form the workpiece into its final shape and surface finish right on the lathe, eliminating the need for secondary grinding.

Inside our machine shop, we have well-maintained turning equipment that is rigid, stable, and accurate enough to successfully accomplish hard turning, which made it a viable solution for us. Since this part featured dimensions of 1.56” in diameter x 0.51” in length, the small length-to-diameter ratio made it an ideal candidate for this process. The material of construction was ASTM A513 type 5 carbon steel tube. This tubing is drawn over a mandrel, which gives it a uniform grain structure and the best combination of strength, hardness, and toughness needed for the final part.

To ensure the products complied with the company’s strict standards, quality assurance involved a number of test and inspection methods. Along with performing visual inspection and Rockwell hardness testing, we used a profilometer to quantify the surface roughness and a bore gage to verify the internal dimensions. Over a period of six weeks from start to finish, we produced 200 of these bushing seals and shipped them to the customer before the deadline.
