Carbide rods made for a miniature milling assembly.
In a 2012 Powder Diffraction study, researchers used carbide rods machined by Extramet Products in a compact laboratory milling assembly.
Extramet’s contribution was to machine supplied carbide into the chamfered cylindrical components described in the paper.
Machining carbide for a research assembly
The researchers developed a miniature assembly for use inside a McCrone Micronizing Mill. The paper identifies Ultra Carbide in Michigan as the supplier of the K6UF material and Extramet Products in Pennsylvania as the machinist.
It describes chamfered rods with the dimensions shown above and uses the notation “h8 ISO mechanical tolerance” in its machining description.
Small components need clear requirements
For a compact carbide component, the important details often extend beyond diameter and length. A chamfer, edge condition or mating surface can affect how the part fits and how it needs to be measured.
Identify those features on the drawing, along with the required finish and inspection method. Extramet’s carbide machining services page explains how geometry, material and tolerances guide the manufacturing discussion.
Bring the material and drawing together
If you already have carbide for the project, include the grade and available material documentation. If material selection is still open, describe the component’s purpose and operating conditions.
A useful quote request brings these details together:
- Finished dimensions, tolerances and mating-part requirements.
- Chamfers, edge conditions and surface finish.
- Quantity, requested delivery date and inspection expectations.
- Material source, grade and available records.
