New Mold Polish Achieves High-Intensity Finish Without High-Intensity Odor


(WHEELING, IL) – Finally, finishing specialists charged with achieving the highest finish possible on tooling, molds, and dies can now easily do so without the intense, unpleasant smell of most polish compounds. Engis Corporation (Wheeling, IL), with more than 60 years of providing superabrasive finishing solutions to die and mold professionals, introduces the latest in the company’s new DiaMold™ family of polishing and finishing compounds: DiaMold™ High Intensity Polish.
Specially formulated for die and mold applications, DiaMold High Intensity Polish not only eliminates the unpleasant odor associated with most mold polish products, it restores surface finish and leaves a brilliant, high-luster sheen with less effort, making mold polishing more cost-effective. Non-hazardous, non-flammable, and non-corrosive, it safely cleans and removes haze from diamond-finished molds, dies, or fixtures without causing spiral webs, cattails, or other fine surface scratches. It also removes plate-out, oxidation, and stains on fine tooling surfaces quickly and cost-effectively, leaving a protective film that slows subsequent oxidation and wear.
DiaMold High-Intensity metal polish works on brass, bronze, chrome, aluminum, and other substrates, and is the perfect follow-up to DiaMold Diamond Compound for mold and die stock removal, lapping, and finishing. Engis Corp. offers a complete selection of diamond compounds, diamond and CBN grinding accessories, polishing stones, and other tools for mold and die finishing and repair – everything for the mold and die finishing professional.

NEW ROBOTIC TOOL COMPENSATION SYSTEM AUTOMATES ENGIS BORE FINISHING PROCESS


WHEELING, IL, USA – A new robotic process that automatically compensates for tool wear is bringing significant labor cost savings, higher yields and increased throughput to single-pass bore finishing operations. The system’s capabilities, features and benefits will be unveiled by Engis Corporation at IMTS 2004 in Booth #B7422.
“This is a highly versatile system that takes the efficiencies of single-pass bore finishing to the next level,” explained Ken Werner, vice president of sales and marketing at Engis. “This system allows the precision bore finishing operations to run with virtually no labor costs”. Another option that is available involves the integration of other machining operations into the automated system for compounded cost savings.
“The key to success of this system is the ability to monitor all of the progressively sized diamond tools individually and automatically make any necessary size compensations due to eventual tool wear.”
Here’s how it works. A central robotic arm picks up incoming parts to be finished and places them into fixtures on the Engis single-pass bore finishing machine. Engis machines are available in a variety of standard and custom models, typically featuring four to six spindles outfitted with high-precision diamond-plated tools. The parts are finished by a series of single passes through the bore. The robotic arm then picks the parts from the machine and swings them over to either another finishing station, such as an OD grinding operation, or to a gauging unit, where it is measured for tolerance before being moved to the final unload station. Based on feedback from the gauge unit, and also after a pre-set number of cycles, the system controller tells the robot to go into what is called a “check” mode. During this check mode, the robotic arm picks parts from each position on the bore finishing machine’s index table and drops these parts onto a gauging device mounted directly to the machine itself. Each part from each of the four-to-six spindle stations on the machine is measured. The robot then changes its end of arm tooling to a unit specially designed for adjusting the diametrical size of the diamond tools, and proceeds to make the required adjustments based on the information calculated through the gauging systems computer.
While there are specialized auto comp tool packages that utilize internal drawbars and servo-driven adjustment mechanisms through the spindles, Werner stated that the robotic approach both simplifies and brings added value to the task.
“With this new multi-functional approach to auto comping, you get the added versatility and benefits that come from incorporating additional finishing and inspection stations into a totally automated, integrated machining cell.”Contact Engis Corporation

NEW ULTRASONIC COOLANT DELIVERY SYSTEM FROMENGIS BOOSTS GRINDING PERFORMANCE


WHEELING, IL – Engis Corporation will launch its new Megasonic Cooling System in the North American machining market at IMTS 2004. The system, on display at IMTS 2004 Booth # B7422, utilizes ultrasonic cooling nozzles to reduce coolant consumption, increase stock removal efficiency, extend grinding wheel life and provide enhanced surface finish characteristics.
The new system of ultrasonic nozzles uses the Megasonic Coolant method, invented by Professor Suzuki Kiyoshi, of the Nippon Institute of Technology. Efficient grinding operations require the supply of an adequate amount of grinding fluid to the grinding point, but the air barrier created by the rotating grinding wheel often reduces the amount of coolant actually reaching the cutting face. Professor Kiyoshi’s invention takes aim at breaking down this barrier.
Grinding hard materials using superabrasive wheels can lead to considerable wheel-wear due to the accumulation of ground chips in the chip pockets of the wheel and the superabrasive grains falling out of the wheel surface. The Megasonic Coolant method uses highly accelerated and focused coolant streams produced by a vibration transducer of megahertz order placed in the nozzle. The resulting high megasonic permeability and vibration acceleration removes these fine particles.
Professor Suzuki has demonstrated that a Megasonic Coolant System can improve performance significantly, due to the coolant reaching the grinding point, thus resulting in more effective cooling and lubrication. Megasonic coolant systems can also be supplied with a sacrificial front nozzle, which is made of a relatively soft material, with an exit facing the grinding wheel. The Megasonic method is particularly applicable to the grinding of very hard materials, such as LCD glass edge polishing and super-hard metals, and results in improved surface finish.
Research undertaken by Professor Suzuki and his team has demonstrated that coolant supplied by Megasonic Coolant Nozzles can improve the grinding ratio, surface quality and grinding efficiency while reducing coolant consumption. In experiments using the Megasonic Floating Nozzle a reduction in wheel wear of up to 40% was observed, in addition to an increase in the grinding ratio of 2 times, and an improvement in surface roughness of up to 30%.
The system is available in North America from Engis Corporation, and will be on display in the Engis exhibit at IMTS 2004, in booth # B7422, along with the company’s Electrogrip® line of custom diamond-plated grinding wheels and products.
