Choosing the right tungsten carbide EDM block for your applications can make all the difference in terms of performance and cost, so it’s important to know what to look for. In this guide, we’ll discuss the benefits of using an EDM block made from tungsten carbide and provide some tips on how to make the right selection.

Determine Your Machining Requirements

When choosing a tungsten carbide EDM block, it’s important to have a good understanding of what your specific machining requirements are. Some factors to consider include the hardness, size, and shape of the material you’re planning for the machine as well as the type of EDM process you’ll be using. Knowing these details will help ensure that the block you select has the properties necessary for your application.

Know The Tungsten Carbide Grade

Tungsten carbide EDM blocks come in a variety of grades and hardness levels, depending on the application. Make sure you know what grade of material is needed for your process. If you're unsure which grade to choose, consult with a specialist or machinery supplier that has expertise in tungsten carbide EDM machining or look at the manufacturer’s product specifications. Different grades offer different performance benefits and can affect the quality of your finished part.

Consider the Sizes of EDM Blocks to Choose 

Consider the sizes you need for your parts or tools. EDM blocks come in a range of standard sizes, from 2mm and 3mm thicknesses up to 20mm, so make sure you choose the right size for your application. Keep in mind that the smaller sizes are better for finer detail work, while larger and longer EDM blocks are suitable for large-scale projects. In addition, you should also check whether the block features chamfered edges or not. Chamfered edges provide smoother machining and higher accuracy by reducing vibrations—an important feature if accuracy is paramount to your project.

Factor in Working Life of EDM Blocks

Before buying a tungsten carbide EDM block, it’s important to consider the working life of the material. The quality and grade of the material affect how long the part lasts during machining operations or its working life. It is recommended that you use the highest-grade material for parts with complex contours, as EDM blocks made from inferior materials may break or wear down quickly. If a jetted EDM block has too low hardness and strength grades, it can lose dimensional accuracy quickly, which reduces its life even further.
