Precision Machining Threaded Tungsten Carbide Grinding Wheel Shaft
This precision-machined tungsten carbide grinding wheel shaft serves as a specialized cutter holder base body for assembling grinding wheel tooling in machine tool grinder equipment.
Material Properties & Advantages
Tungsten carbide, as a superhard metal material, offers exceptional physical stability with high hardness, superior strength, excellent wear resistance, high temperature tolerance, vibration resistance, corrosion resistance, and optimal steel properties. These characteristics make it ideal for spindle grinding rods in precision machine tool grinders.
Grinding wheel bars, grinding rods, and cutter bars used in high-precision machine tool mechanical grinders must withstand high-speed operating conditions while maintaining stable performance. Tungsten steel grinding rods precision-machined from carbide material provide the optimal solution for these demanding applications.
Custom Manufacturing Specifications
Our company customizes production according to mechanical grinder grinding wheel rod tooling drawings, processing both tungsten steel internal and external threads to meet precision tolerance requirements for straightness, roundness, and runout.
Dimensions: φ16*φ14*M9*φ8*M2.5*φ1.6*40
Operating conditions include precision grinding of M2.5 internal threads and M9 external threads at rotation speeds up to 100,000 rpm, meeting position tolerance matching requirements of 0.002 for circular runout and 0.003 for concentricity and true roundness.
