Introduction - Catalog #55 Effective 3/1/2017 Since 1937, okum has manufactured the finest cutting tools in the world. s industries have changed, okum s principals have remained the same; lways meet or exceed our customer s expectations. We manufacture a standard line of oring, Recessing and Threading tools as well as utomatic Recessing heads, special grooving tools, and special boring bars. We also work with OEM partners to provide precise and cost effective solutions allowing the end user to produce superior parts. If our extensive stock of standards does not offer a solution, our experienced team of engineers will work with you to design and manufacture a special in our plant. s of this printing, okum Tool Company is entering its 80th year of manufacturing. We are proud to offer solutions which are more precise and cost effective compared with other machining methods. Whether utilized in the machining of the common products you see daily, or the creation of a unique prototype, it is likely a okum tool was involved. Our cutting tools are available direct or offered through knowledgeable distributors. lease contact us today to assist you. OKUM TOO COMNY inc TRDE MRK REG. U.S. T. O.

ORING TOOS The okum rinciple okum oring tools cover a minimum bore diameter range from 1 16 to 2, with 19 sizes offered in small fractional increments. Each tool for any given size is the largest cross section that will enter that hole. Effective boring range is from 1 16 to 6 hole. Constant radial and helical relief Our oring tools are made from the highest quality SS, C2(Micrograin) and C7 Carbide Maximum rigidity - roduces round, straight holes ree cutting - minimum deflection Short Stubby tools - minimum overhang Superior finish - May eliminate need for grinding operation owest cost per cutting edge - Offers many regrinds Two Styles of tool offered Style - eavier Cuts, Thru oring, Quality inish Style - est ossible inish, oring/acing/ottoming, light to medium cuts ll offered from stock in a full range of sizes and types okum Cutter type tools offer a wide range of interchangeable shanks dvantages - Radial and elical Relief The drawing below shows a typical boring tool superimposed on a okum boring tool of the same relative size. The areas in red show the greater back up strength of the okum rinciple - which results in longer tool life and superior finish. The radial angle on a okum Tool is the relief on the outside diameter of the cutting head. We believe this angle should be held constant to a tolerance of +/- 3 minutes of one degree. Each okum boring tool is ground within this specification for precise machining throughout its long life.

The shanks are made from a tough grade of carbide for maximum strength that has 2.8 times the rigidity of heat treated high speed steel of the same dimensions. This construction is of great help in securing that last tenth (.0001) of accuracy when the depth of bore is more than three times its diameter. You can see what a problem it is to bore a 1 8 diameter hole 1 1 2 deep. The SC-3 tool is ideal for this job. -4 Replacing cutting heads - When cutting heads are used up after many regrinds, the tools may be returned to okum to have the heads replaced at a fraction of the cost of a new boring tool.

ORING TOOS - Trouble Shooting ints SS, CRIDE NECK, CRIDE TIED ORING TOOS Over the years we have found that the okum regrinding fixtures normally will solve 90 percent of any problems a customer has to maintaining size, will help produce a better finish and make a tool last longer. The trouble shooting tips below are based on the assumption that the oring Tool has been properly resharpend. ROEM: OSSIE CUSES: inish on part shows chatter marks. Not cceptable. 1. Cutting tool head too small for hole. 2. ength of tool excessively long. 3. oose Spindle, part is not chucked securely. 4. Vibration through external source, i.e. a punch press operating nearby. 5. Insufficient surface footage. 6. eed too coarse. ROEM: OSSIE CUSES: igh Speed Steel burning up. 1. Material being cut is too hard, over 28 Rockwell C. 2. Surface footage beyond recommendation. ROEM: OSSIE CUSES: Carbide tip is chipping at cutting point. 1. Surface footage is too slow. 2. Chip being removed by tool is entangling around carbide head and is rechipping tool. 3. Too hard a grade of carbide is being used for application. 4. oor material quality or impurities may cause interrupted type cut. 5. External vibration from other machines or from the machine itself. 6. Machine has stopped while tool is still engaged in cut. -20 OKUM TOO COMNY inc TRDE MRK REG. U.S. T. O.
