RUF US, Inc.OFFERS GEAR GRINDERS VALUE IN BRIQUETTING SYSTEMS

Gear and other grinding operations are finding the value they thought was lost in their grinding sludge. The bonuses of increased operational efficiencies and safer working conditions are realized once companies start using a briquetting system.

Corrugated Replacements, Inc., a developer of machine replacement parts for the corrugated board, steel, poultry and satellite industries, and Horsburgh-Scott, a provider of industrial gears and custom gear drives for steel, aluminum, tire, rubber plants and wind turbines, are just two of the many companies who looked to RUF Briquetting Systems to help squeeze value out of product they previously viewed as lost.

Just one year ago, managing monthly expenses of time, money and resourc-es dealing with swarf produced in the grinding process was a reality for Corrugated Replacements. Before pur-chasing a briquetting system, dirty swarf was stored in barrels on the production floor, and then disposed of by a cost-ly hazardous waste removal company. With the briquetting system, things have changed. “We were able to turn some-thing that was a 100 percent expendi-ture process into a profitable revenue stream and reuse reclaimed coolant,” said Corrugated Replacements plant and engineering manager Scott Wallis. “It has been a win-win for our business.”

Similarly, the Horsburgh-Scott pro-duction process was positively impacted after the installation of a briquetting sys-tem in February of this year. “The bri-quetter has helped our operation reclaim more than 1,650 gallons of oil from our swarf,” said Horsburgh-Scott manufac-turing engineer Luciana Talpa. “The RUF machine works amazingly; it sim-plified the business and will pay for itself in less than a year.”

Horsburgh-Scott’s grinding sludge contained 63 percent oil by weight. The briquetting process is able to reclaim nearly all of the oil from this saturat-ed grinding sludge. The reclaimed oil is then reused, reducing the amount of new oil purchases needed for their gear grinding process.

Reducing oil and coolant loss is just part of the added efficiency of the bri-quetting system. Both companies have also reduced or eliminated hazardous waste costs, turning it into a revenue stream by selling the briquettes as scrap to steel mills. Although it was not part of the initial goal, by improving opera-tion efficiency and reducing expenses for

wasted material and swarf, briquetting and reclaiming product has made for a safer work environment.

“The barrels where swarf was previ-ously stored, waiting for disposal, cre-ated a heat safety issue,” said Wallis. “Not only did we regain a significant amount of floor space, but we also eliminated the need to store hazardous waste.”

17June 2014 | GEAR TECHNOLOGY

These two companies, along with oth-ers in the metal grinding industry, have improved efficiency, safety, productiv-ity and developed a new revenue stream, simply by recycling their own product through the briquetting process.

Burka-KosmosOFFERS NEW GEAR GRINDING WHEEL

The Mira Ice product line of gear grinding wheels was developed in order to meet the requirements of profile grinding larger gears. A new approach in the development of this grinding wheel enables results to be achieved in terms of econom-ic efficiency and cool grinding that were previously unheard of in the profile grinding of gears. The Mira Ice grinding wheel has been further optimized on the basis of the lead-ing product line from Burka-Kosmos. The use of new grain qualities and the new high-strength bond system guarantees particularly cool grinding. Longer cycle times between dress-ing and shorter grinding times sig-nificantly reduce the processing costs per gear. During testing against the Burka-Kosmos SK23 ceramic grind-ing wheel stock removal volume was increased by almost 400 percent on a 3.6 diametral pitch gear. This increase, along with the need for fewer dressing cycles, resulted in a 30 percent reduction in total machining time.
