Turned Ground & Polished (TG&P)

When you have high-performance requirements demanding precise roundness, straightness, and surface finish, Ace Grinding’s Turned, Ground, and Polished bar stock is your solution. In order to avoid early wear and tear on shafts and bearings, metal shafts being crafted for high-speed applications require a high degree of precision. To achieve this level of precision, Ace Grinding uses a process known as Turned, Ground, & Polished (TGP). As the name implies, this is a three-step process that can turn coarse, imperfect metal rods into straight shafts with smooth finishes. Purchasing TGP bar stock saves customers not only the time it would take to have raw materials turned, ground, and polished, but the money that would need to be spent on equipment, labor, and materials.

TGP shafting begins with hot rolled or cold drawn bar being turned in a lathe for excess material to be shaved off. Once the steel bar has reached its intended size, it is ground with a grinding wheel to remove an even smaller amount of material that could cause uneven wear or balancing issues. As soon as the proper dimensions are met, the bar is finally polished with a polishing wheel, giving the bar its smooth surface. Once all is said and done, we are left with a turned, ground, and polished bar that can be used for tool shanks, pistons rods, bolts, axles, motor shafts, tie rods, and more.

Bearing Shaft Quality (BSQ) Stainless Steel Bar

When it comes to bearing shaft quality requirements, you will find Ace Grinding gives customers the critical repeatability that they rely upon. A properly sized bearing shaft with a smooth, polished surface can extend not only the lifespan of the shaft itself but the full bearing assembly. That is why we insist on using nothing but the best Bearing Shaft Quality (BSQ) bar to create bearing shafts for precision tolerance bearings. Bearing shafts require reliability and repeatability, something that Ace Grinding has been offering customers for over 60 years.
