Solid carbide gear hobs can be used in shell or shank design to cut gears with or without coolant, and are available in shell style with keyway or end drives, and various shank designs to fit most hobbing machines.
Carbide hobs permit cutting speeds into the high- speed cutting (HSC) range, and significantly higher than those possible with high- speed steel hobs. The development of suitably rated hobbing machines enables the advantages of carbide hobs to be exploited in practical use.
Solid Carbide Gear Hob for Metal Cutting Features
1. High cutting speeds
2. Short maching times
3. A longer tool life than conventional HSS cutter
4. Time saving per piece for gear manufacture
5. High productivity
6. Machining precision
7. Improved working environment by employing dry cutting
8. Very suitability for dry machining
9. Lower gear generation costs
Solid Carbide Gear Hob for Metal Cutting Applications
Solid Carbide gear hobs are used for cutting thread on different grades steel and metal. They are also used for high speed milling, suitable for processing aluminum alloy, copper alloy, alloy steel, carbon steel, stainless steel, nickel alloy and so on.
Solid Carbide gear hobs are best choice to cut thread due to superior physical properties, high hardness and toughness.
