METHOD OF MAKING CUTTERS.
Specification of Letters Patent.
Patented Nov. 21, who.
Application filed March 27, 1916. Serial No. 86,831.
State of Connecticut, have invented certain,
new and useful Improvements in Methods of Making Cutters, of which the following is a specification.
"This invention relates to a method of making cutters.
The cutter may be of any suitable character, such as a milling cutter. The method comprises the insertion of a plurality of cutter blades of high speed steel into the peripheral grooves of a.body of softer steel, so that the blades will be gripped by the side walls of the grooves, supporting binding means for the blades on an end of the body adjacent the butts of the blades, which binding means fuses approximately at the hardening heat of the blades, and then hardening the blades to efiect fusion of the binding means and the running of the fused material into said grooves.
ing the method drawings: 7
Figure l is an end elevation of a milling cutter made in accordance with the method; Fig. 2 is a sectional side elevation, and Fig. the same with the parts thereof connected and with the binder positioned thereon and in readiness to be subjected to the hardening operation.
Like characters refer to like parts throughout the several views.
The numeral 2 denotes the body of a cutter which in the present case is of milling This body has in its periphery a number of longitudinally extending grooves or seats-3 spaced equidistantly from each other. Into these grooves I prefer to drive the butts of the cutting blades 4. When the blades are positioned the side walls of the grooves will grip the butt of the shank portions of the blades. With the body of soft steel upright and with the blades thus into effect, and in these per sets the blades a will supporting binding gripped I support upon the body binding means. The band or ring 5 can be utilized for this purpose. This band or ring prefer,- ably consists of copper wire. The blades as will be understood are of high speed steel. They are hardened by heat, and while they are being hardened, the binding means is fused. The heat for hardening is approximately 2200 degrees Fahrenheit, and this heat will melt the copper.
When the soft metal body with the series "of blades carried thereby has placed upon it the copper ring or equivalent binding means, the whole is placed in a furnace, and when the temperature mentioned is reached, the blades will be hardened, and at the same time the copper will fuse and will flow into the grooves 3. In melting the wire any suitable flux may be employed. 1 have found boraX of commerce satisfactory in this respect. When the wire is fused and after it has run into the grooves, the cutter is removed from the furnace and dipped in its entirety into an oil bath which is followed In the drawings I show a way of carryby a setting of the copper. When this copbe substantially and permanently bound to the body 2. atlclaimis:
A method of making cutters comprising inserting a plurality of cutter blades of high speed steel into the peripheral grooves of a body of softer steel, so that the blades will be gripped by the side walls of the grooves, means for the blades on an end of the b0 y adjacent the butts of said blades and which fuses approximately at the hardening heat of the blades, and then hardening the blades to effect fusion of the-binding means and the running of the fused material into said grooves.
In testimony whereof I afix my signature in presence of two witnesses.
