Meister recently had an inquiry from a customer who needed to grind the bores on a trial order of hardened automotive sleeves, but their grinding setup was not sufficient. Their Cylindrical bore grinder was relatively new, but they did not have a rotary dresser installed, only a single-point diamond, and when attempting to grind the parts with aluminum oxide wheels the wear rates were very high and they were unable to maintain a consistent process.
They really wanted to use CBN wheels, but they couldn’t justify the investment in a rotary dressing spindle unless they landed a longer term contract with their customer, which would never be possible unless they could produce this initial order to exceptional quality. Therein lied their dilemma.
The solution was a stationary hDD dressing tool, utilizing Meister’s newest hybrid-bond technology, combining the porosity of vitrified bond with the wear resistance of metal bond. This tool was combined with a Meister HPB vitrified-bonded CBN wheel.
Not only did the solution work, but the customer was able to land the contract and is now looking to expand their process.
