CASE STUDY: HPL Technology for EPS Steering Nut

New wheel technology achieves higher throughputs and better micro-precision accuracy while nearly doubling the parts per wheel.

This case study summarizes the successful application of HPL (High Performance Lubrication) Vitrified CBN wheels in a demanding application for Electronic Power Steering.

In this application, the customer was grinding the ball tracks in an EPS Steering Nut with a vitrified CBN wheel from another manufacturer.  The application was demanding because of heavy stock removal, aggressive feeds, difficult coolant application, and asymmetrical loading of the grinding wheel. The trick was to find a wheel that was tough enough to stand up to the rigors of the application, while at the same time producing a smoother finish, a burn/crack-free surface, and reduced cost/part.

Enter HPL…

HPL combines a high concentration of premium grade CBN crystals with a durable, porous, and intrinsically lubricated bonding matrix, which allows faster, cooler, and more efficient grinding with less wheel wear. The technology was tailor-made for this application, and with HPL the customer was able to speed up the process and drastically reduce abrasive cost/part, while also improving the surface finish and eliminating the onset of cracks and burns.  Below is a summary of the process and the results.

This case study is just one example of the benefits of this new technology. HPL can also produce impressive results in applications such as deep-bore fuel injection nozzles, lash adjusters and tappets, creep-feed grinding of tool steels & superalloys, and out-of-round grinding for punches. Stay tuned for additional case studies coming soon.

Meister’s New HPL Wheels Extend HPB Technology!

Intrinsic lubrication delivers faster grinding without burning...

According to Dr. Peter Beyer, Meister Abrasives’ CEO and Chief Technologist, the new HPL super abrasive wheels are a significant extension of the Company’s proprietary HPB (High Performance Bonding Technology).  It departs from conventional approaches to manufacturing wheels with lubricating properties that rely on fillers that can clog the wheel’s pores and are less likely to distribute lubricating properties evenly.

Meister’s NEW HPL Wheels rely on premium grade CBN crystals fixed within a durable, porous, intrinsically lubricated bonding matrix to allow substantially faster grinding of difficult materials without sacrificing quality due to wheel loading and/or part burning.

Applications for the new HPL abrasives technology include:

Electronic Power Steering (EPS) ball nut track

  • Deep bore grinding with limited coolant access, such as fuel injection nozzle components.
  • Blind-end bore grinding such as lash adjusters and tappets.
  • Heavy-stock form-grinding applications such as electronic power steering (EPS) ball-nut tracks.
  • Creep-feed grinding of tool steels and superalloys.
  • High stock removal out-of-round grinding for punches.
  • Any application where the concentration of oil and lubricant are less than ideal or the flow of coolant is impeded, as is the case with deep bores.

Dr. Beyer indicated that R&D for this technology has been going on for about 18 months. He said, “Early adapters in Europe and the United States have tested dozens of application-specific HPL recipes with excellent results. Although the extent of performance improvements varies from application to application, I can say that our customers rarely switch to a new technology for existing production grinding applications if they are not realizing a 25% or better improvement in productivity.”

HPL (High Performance Lubrication) CBN grinding wheels are available for both internal and external grinding with mesh sizes ranging from 60 to 1200.

Here’s Some Reading That’s Anything But Boring!

“Top Ten Bore Grinding Problems…and how to solve them today” now available as a white paper.

Bore grinding is probably one of the most difficult grinding applications to master. That’s why we created a series of blogs to address the most frequently encountered problems and how they can be resolved. These problems/solutions evolved from a collaborative effort by Meister’s Applications Team.

The blogs proved so popular that we’ve compiled them into one comprehensive white paper complete with magnified graphics to add clarity. You can still find the individual blog chapters in the Meister Toolbox.  However, if you prefer a version with everything in one place for fast, convenient access, download the white paper here.

If, after reading the white paper, you need to go deeper, contact a Meister Applications Engineer and we’ll do our best to help. We may be able to offer just the right solution.

New HPL Wheel Technology

Delivers Faster Grinding Without Burning

Meister Abrasives’ New HPL (High Performance Lubrication) Grinding Wheels rely on premium grade CBN crystals fixed within a durable, porous, intrinsically lubricated bonding matrix for faster grinding of difficult materials without sacrificing quality due to wheel loading and/or part burning.

HPL wheels contain a lubricant that is intrinsic to the bonding matrix chemistry and is released uniformly as the wheel breaks down. Wheels manufactured with this technology minimize friction from bond//workpiece interactions, minimize heat generation, and deter the onset of metal loading into the bond structure.

HPL technology also makes it possible to implement wheel characteristics that are not economically feasible with standard vitrified bondings. The superior grit retention and lubricating properties of the bond make it possible to utilize high concentrations of premium grade CBN crystals that in a standard bonding matrix would generate too much pressure and heat. This allows Meister to manufacture wheels with superior cutting performance and wear resistance to others on the market.

The unique properties of these intrinsically lubricated wheels address a wide range of problems including: burning of parts, wheel loading, excessive wheel wear due to heat related issues, and quality issues due to temperature sensitive materials. They are ideal for CBN grinding applications requiring maximum wheel sharpness and lubricity.

HPL (High Performance Lubrication) CBN grinding wheels are available for both internal and external grinding with mesh sizes ranging from 60 to 1200.

CASE STUDY: How Dress Optimization Pays Dividends

This case study demonstrates how a customer used Meister’s Dress Calculation Tool to optimize their dressing process and significantly improve grinding performance.

The part was a hardened thin-walled steel sleeve. The customer was dissatisfied with the results he was obtaining from a bore grinding process using a vitrified-bonded CBN wheel. Grinding pressure was too high, which resulted in deformation of the part and poor roundness results. The only viable solution at the time was to slow down the process to an unacceptable cycle time of 45-seconds. The production requirement was to be under 35 seconds.

In addition to the slow cycle time and part deflection, the customer also complained that after the dressing cycle, they were seeing a size drop along with increased taper that only corrected itself after grinding 2-3 parts.

After reviewing the wheel and dresser designs, Meister engineers decided to have a closer look at the dressing process. It was determined the dress process was unnecessarily dulling the CBN wheel, causing it to build too much pressure during the grind cycle. This resulted in quill deflection which, in turn, caused the taper and size control issues after dress as well as the part deflection and roundness problems. Using the Meister Dress Calculation Tool, the following chart shows the changes that were made to improve the dressing process and the grinding results.

A screen shot of the full calculation tool can be seen by clicking the thumbnail image to the left.

Results/Conclusions: Moving from a counter-directional to a uni-directional dress (both wheel and dresser rotating in the same direction), combined with a faster dress traverse rate resulted in a more open and aggressive cutting wheel, so the customer was able to increase feed rates and get the cycle time down from 45 seconds to 35 seconds, while keeping the roundness in spec. Furthermore, taper and size control dramatically improved, so there were no more dimensional issues after dressing. As a bonus, since the wheel was cutting more efficiently, the customer found he could increase skip dress from 10 to 13 parts, allowing a much improved wheel life.
