Picking the right carbide punches means thinking about many things. Every factory job is different, so you must look at the material, the process, and what you want to make. Here is a checklist to help you choose:
Operating Conditions:
Check how hard the material is and how much space is between the punch and the hole. For example, stainless steel often needs a punch space of 12%–15% and a hardness of HRC 62–65.
Carbide Grade:
Pick the grade for your job. KG7 is good for very fine work and high accuracy. V30 is tough and works for thick metal. CD650 is best for making lots of parts over time.
Precision and Surface Treatment:
Find punches that are very exact, like edge straightness within 0.003 mm/m and diameter tolerance of ±0.001 mm. Special surface treatments, like mirror polishing or TiAlN coating, can help punches work better.
Structural Design:
Choose the right head shape and features that stop damage. A curve of at least 0.1 mm helps stop chipping.
Maintenance:
Follow rules for when to fix or sharpen punches. Check them often to keep them working well and lasting longer.
Customization:
You can get custom carbide punches for special shapes or needs. These help meet strict rules and make work faster.
Tip: High-precision carbide punches use the best materials and advanced methods. This keeps them very exact and working well, even in tough places.
Carbide punches are great because they do not wear out fast and keep their shape during fast stamping. They work well in hard jobs, but they can break if not handled carefully. Picking the right carbide grade gives a good mix of wear resistance and toughness. Cobalt and grain size are important for this balance. Using the right fluids, without sulfur or chlorine, helps stop damage and keeps punches working well.
The chart below shows how different tungsten carbide grades change punch life. Smaller grains make punches harder and more resistant to wear, but also more likely to break. Bigger grains make punches tougher but less resistant to wear. The best mix makes punches last longer and saves money.
Choosing between tungsten and tungsten carbide punches depends on what you need. Each one has good and bad points. The table below shows the main properties and costs for each punch type:
