How to machine tungsten carbide. Cemented carbide materials are made of metal powder tungsten carbide powder and solid binders such as bonding metals such as cobalt, iron, nickel, etc. through pressing, sintering and other processes. They have high hardness (hardness range 86HRA-94HRA), high strength, high wear resistance and other excellent ...

Machining tungsten carbide requires careful consideration of tool selection, workpiece fixturing, and machining parameters. Grinding is the most common and cost-effective method of machining tungsten carbide, while EDM and laser cutting are suitable for complex shapes and thin sections.

2023年1月24日 · Tungsten is a notorious destroyer of cutting tools and cause of headaches for machinists. But with the right tools and techniques, this metal can be tamed. Working with tungsten is never easy, but these tips can help machinists complete a workpiece successfully.

2024年6月25日 · What is required to drill through Tungsten? Carbide tipped or solid carbide drills are preferred since the material is so hard. What is required to tap Tungsten? Use straight flute, high alloy taps. For small holes, thread forming taps can be used.

Carbide tipped or solid carbide drills are suggested. Increased clearance angles and automatic feeds will help to avoid binding and seizing. Carbide drills will give a better tool life. Use of coolant or lubricant is highly recommended, chlorinated oil can be used as a coolant.

MACHINING GUIDE FOR TUNGSTEN ALLOYS [as per ASTM B 777, EU RoHS Directive Compliant] TOOLS: C-2 Grade carbide tooling is recommended. Use as generous a nose radius as possible. OPERATIONS: Note: cooling tools; coolant can be used. DRILLING/TAPPING: with air or coolant such as Molydisulfide cutting fluid.

2012年11月25日 · You can make your own tungsten carbide. Popular Science, February 2009 had an article on “Building a Tough Bit”. However what you get will almost certainly not be industrial quality. You can turn a complete novice loose in your machine shop with everything they need but that doesn’t mean their finished part will be anywhere near good enough.

In order to machine tungsten, you need right cutting tools. We have tried different tool materials such as diamond, CBN, and ceramics. However none of them were as good as tungsten carbide in terms of durability and cost effectiveness. Among tungsten carbide, we choose the one with high hardness and toughness.

2023年12月21日 · Machining methods for carbide, particularly tungsten carbide, require careful selection based on the part’s drawing and shape. This article will cover various machining methods suitable for different scenarios, from simple cutting to complex shapes, and explore effective techniques for ensuring precision and quality.

In general, the production process of tungsten carbide includes several main steps such as raw material preparation, mixing, drying, sintering and post-processing. By reasonably controlling the parameters and process requirements of these steps, tungsten carbide materials with stable quality can be obtained.
