Solid carbide rods blanks without coolant channels and
solid carbide center ground rods
We offer:
1.Pressed and extruded and CIP unground,ground and polished rods with or without chamfer.
2.Rod products that can be ground to H6 tolerance.
3,Tungsten carbide rods are mainly used for end mills,remaers,drills,countersinks,engraving tools,routers
and other rotary tools.
4.Also we provide other sizes upon request. Please contact us if you need a size customized.
solid tungsten carbide rods:
1. Grade: 10% cobalt and 12% cobalt recommend
2. Size: Diameter 4--30mm available
3. Certification: ISO9001,
4. Mirror polished to h6 available
5. Metric and Inch dimensions available
6. Standard length: 330mm/310mm and can cut into different length as per requirments
Advantages of product:
1. Adopting spray drying tower granulation, raw material with low oxygen content, contamination,
the flowability, apparent density particle and granulate is uniform;
2. Adopting high-precision extrusion molding machine, uniform product density, precise dimension, high
roundness, and straightness;
3. Adopting advanced HIP sintering, effectively eliminate the internal holes and defects, the product has
good compactness, high strength, good polishing performance;
4.Adopting a special stress-relief process to eliminate the internal stress of products to further enhance the
product strength and improve the microstructure;
5.Precision grinding machine processing, ground rod can reach h6 tolerance.
The specification range of blank and grinding tungsten carbide rod:
1. WC Grain size range: 0.4~0.6μ.m; 0.6~0.9μ.m; 1.0~1.3μ.m; 1.4~2.0μ.m.
2. Diameter range: 3mm--40mm;
3. Length range: 3mm--350mm;
4. Diameter Grade: h5(H5), h6(H6), h7(H7), h8(H8), h9(H9).
5. Sphericity tolerance range: 0.001mm ~ 0.009mm;
6. Linearity tolerance range: 0.001mm~0.2mm;
7. Surface Roughness can be reached to: RA0.04.(reach a mirror effect surface after accurate grinding)
Production Process:
Below are the production processes of tungsten carbide rods, to ensure high quality, we assureed our
customers that:
1. All materials are tested in terms of density, hardness and T.R.S before use.
2. Every piece of product goes through in-process and final inspection.
3. Every batch of product can be traced.
