Patented Nov. 21, 1933 UNITED STATES METHOD or raonucmo CUTTING Ann GRINDING TOOLS Paul Hopi, Berlin-Lichterlelde, Germany No Drawing. Application January 4, 1933, Serial No. 650,141, and in Ge many December 2,
2 Claims. (o1. 51-278)- In ordinary dental practice, grinding tools are employed which. are either produced ceramically from solid grinding material, or composed of a copper support to which the grinding material is 6 connected by pressure or other suitable means.
The first kind of grinding tools have the disadvantage of losing their shape during use, and neither kind of tool is suitable for all kinds oi. work, particularly such as requires tools of a very l fine character capable of resisting bending stresses.
The object of the present invention is to produce very fine cutting and grinding tools which will. at the same time be sufllciently resistive for 16 operating on hard enamel and porcelain without bending, and the invention consists in employing a support of hard metal such as iron, steel (in-- cluding hardened steel), coating said support with a soft metal and connecting the grinding 20 material to the support through the medium of the coating.
The coating may be applied to the support either galvanically or by dipping, soldering or p y The grinding material may consist of diamond, silica, carbide or like granules and pressed or hammered into the coating or otherwise attached thereto in known manner. Finally a coating of hard metal, capable of resisting acids and bases, is applied to the tool, either galvanically or by spraying, in order to secure the grinding material eilectively to the support and to protect the soft metal from abrasive and corrosive influences.
I claim:
1. A method 0! securing granular grinding material to a support of hard metal, consisting in coating the support with soft metal, pressing the grinding material into the coating, and coating 7 the tool thus obtained with a hard, noncorrosive metal.
2. A method of securing grinding material to a support of hard metal, consisting in coating the support with soft metal, pressing the grinding material into the coating, and plating the tool thus-obtained galvanically with a hard, noncorrosive metal.
