Otec Precision Finish, Inc. of North Kingston, R.I., (www.otecusa.com) has developed a new type of centrifugal disc finishing machine that the company says meets stringent industry demands for smooth surfaces on workpieces subject to mechanical stress in miniaturized assemblies.
The company says it has used tribology — the study of friction, lubrication and wear on surfaces — to develop a secondary deburring process that preserves precise measurement tolerances achieved by final grinding and honing processes. Otec also says its new process offers increased protection to delicate work parts.
The company says its process uses a commercial-grade oil to replace the traditional water/compound mix technology to remove micro-burrs on workpieces without compromising the dimensional integrity achieved through final grinding. The company says the oilbased deburring medium helps to save costs because it eliminates the need to degrease parts before processing, dry them after processing and re-grease them subsequently, while also protecting parts from rust and corrosion.
Otec also said the oil helps to protect the processing media, allowing both the media and to oil to be re-circulated and keeping consumable costs low.
The company's CF-Oil machines include separators that sort workpieces and media, and can be connected to a central filtration system.
