TH Vina solutions for Powertrain industry

Powertrain components are complex and varied, and often require multiple abrasive process steps. That’s why TH Vina offers a full portfolio of precision abrasives for grinding and finishing the many substrates found in these systems. Whether you’re manufacturing turbochargers or grinding transmission gears, there’s a go-to TH Vina abrasive solution to help you get the job done right.

Gear Grinding

Requires high precision throughout the process, and it is important to use the right grinding wheel for the application. The selection of abrasive material and wheel configuration depends on the base alloy, tooth geometry and size of the production run, among other factors. TH Vina offers full range of abrasives and wheels from top manufacturers can help you meet the growing demand for tighter dimensional tolerances and shorter production schedules, even with difficult-to-grind materials.

Camshaft & Crankshaft Grinding

TH Vina's comprehensive abrasives portfolio offers solutions from rough grinding to superfinishing of steel and cast steel alloys – ideal for camshaft and crankshaft applications.

Crankshaft Grinding

Cylindrical Grinding

As cylindrical grinding technology continues to evolve, our wide variety of high-quality grinding wheels advance remove material faster, at precise tolerances, without damaging the substrate. We have wheels available for the most popular worm grinding, form grinding, plunge grinding and transverse grinding machines.

Centerless Grinding

Because of its speed and relative economy, centerless grinding has traditionally been used for higher volume processing of cylindrical shapes. However, advances in both machine tool and grinding wheel technology have made centerless grinding a viable alternative for small and medium production runs, including those requiring tight tolerances and fine finishes.

TH Vina offers a broad range of wheel constructions optimized for centerless grinding. We can also help you optimize your process with grinding and dressing parameters such as feed rates, infeeds, wheels speeds and more that can be directly employed in your CNC equipment.

Centerless Grinding

Microfinishing

A microfinishing process employs rigid shoes to support the abrasive film. The workpiece, such as a crankshaft or a camshaft, is turned and oscillated between centers as 2shoes introduce the abrasive to the workpiece. Fresh abrasive is incrementally indexed after each part is processed, resulting in uniform stock removal and finish, part after part. Microfinishing removes the damaged or amorphous layers to improve the surface finish and roundness of the part.

Our offered Microfinishing Film is a fast cutting abrasive that can produce consistent, predictable and repeatable high quality finishes. The abrasive particles are electrostatically oriented, then resin-bonded to a polyester film backing to give an aggressive cut with a uniform finish. Available in 9–100 micron grades.
