Effectively Machining Composites Using Compression Cutters
Carbon fiber, carbon fiber reinforced plastic (CFRP) and other composite materials used in aerospace, automotive, wind turbine components and other uses, are increasingly be used by designers. Their strong, light and thermally stable qualities are easy to appreciate. These qualities sometimes cause machinists to struggle with milling and drilling processes.
Cutting tool life can be very low due to the fact that these composites are highly abrasive. The low-thermal-conductivity materials have a problem with heat while machining. They do not produce a chip of any decent size, thus not allowing the chips to carry away heat from the machining process. Therefore, using the incorrect tool or even a dull one can cause the resin in the material to burn or melt. In addition, composites are constructed using layers of material held together by resin; they are disposed to splintering and delamination as they are machined.
Cutting Tools Chicago aka General Cutting Tools with Onsrud offers six flute cutting tools purposely designed with specific geometries and coatings for composites to overcome their machining challenges. Their compression cutters have intersecting up cut and down cut spiral flutes push the layers of the composite material together during machining to prevent delamination. Also, the resin is prevented from burning due to the high positive rake angles, delivering sharp, clean cuts. Diamond coating over the tool adds significant wear resistance caused by highly abrasive composites.

Special Cutting Tools
Special CNC Ground End Mill
Chicago Cutting Tools aka General Cutting Tools is your premier source of special cutting tools. Special cutting tools can be made to a specific cutting diameter, have a corner radius, special cutting helix, special cylindrical land, special flute shape, form relieved geometry, form ground flutes, special chamfer, special tip angle, modified shank, reduced shank, single flute, multi flute, roughing, general purpose, finishing, high speed steel (HSS), high speed cobalt (HSCO, M42), carbide tipped, and solid carbide. We make: porting tools, end mills, milling cutters, step tools, reamers, gages, keyway cutters, indexable inserts, resharpening and reconditioning of tools also. Seven-axis CNC tool cutter grinders insure you get exactally the same tool every time regardless of the amount of time between orders.
We make specialty cutters designed for cutting: aluminum, ferrous, non-ferrous, low carbon steel, medium carbon steel, high carbon steel (4140, 4150, 4340, 52100, 6150, 8620), tool steel (A2, A6, A9, A11, D2, H13, L6, M1, M2, M3, M4, M7, M35, M42, M62, P20, T4, T8, 01, 06,S5, S7), high speed steel, super high speed (Rex 20, Rex 45, Rex 54, T15, Rex 76, and Rex 121), cast iron, titanium, powdered metals (CPM 1V, CPM 3V, CPM 9V, CPM 10V, CPM 15V, A11, M4, T15), high vanadium (CPM M4, CPM Rex 54, CPM T15, CPM Rex 76, and CPM Rex 121), alloys, super alloys, nickel based super alloys, high temperature alloys (Haynes, Incoloy, Inconel, Invar, Super Invar, Mu Metal, Rene, Hastelloy, Haynes, Kovar, Multimet, Maraging, Nickel, Waspaloy, Monel, Permendur, Hiperco, Nitronic), and Stainless Steel(414, 416, 420, 440, 440C, and 17Cr-4Ni), Brass (soft, half hard, full hard).

Mueller Reamers for Trimming Plastic Bottles
Mueller Deflashing Reamer
Full custom, special tooling can be made at General Cutting Tools. General Cutting Tools AKA Cutting Tools Chicago has been manufacturing these special, world-class quality tooling for plastic bottle manufacturers for over 30 years. These are used for removing the flashing burr from the openings on plastic bottles. The catch to making these is that we had to anticipate the size of the opening due to the plastic has not completely cured.
General Cutting Tools master toolmakers uses 7 axis CNC (Computer Numeric Control) tool cutter grinders and the highest quality abrasives to produce our tooling. We have the experience and equipment to make the right tool for you, the first time, and you will not have to wait a long time to get them.
