Carbide Grinding vs. EDM Wiring
Doutt Tool specialize in precision grinding miniature carbide punches that many other tool shops choose to Wire EDM and their reasoning is simple - wiring carbide is easy and cheap, internal radii can be eliminated by making tiny undercuts written into the cutting program.
Risks Inherent to EDM
Here's the catch, the surface finish on wired carbide has surface micro fractures, this is no problem for a full sized punch but it's sudden death to tiny, highly stressed areas of a small punch working at up to 800 strokes a minute. Breakages are unpredictable but not surprising.
We consider this risk of fracture unacceptable so we always grind miniature punches.
Grinding Expertise
We are experts in surface grinding carbide micro punches and we know that grinding will give a surface finish entirely free from any micro fracture defects. Our toolmakers select from a range of 500 pre-dressed diamond wheels which gives them the capability to grind virtually any profile carbide tooling - take a look at the Micro Punches selection below.Doutt Tool designed and built their own custom fixture to dress diamond wheels with internal radii from .002" to .800" and outside radii up to 1.000". Our inventory of 500 diamond wheels are pre-dressed with radii from .002" to .034" in .001" steps and various other radii to .800".
Cost Saving
With this level of support our toolmakers can concentrate on what they do best - producing high quality carbide tooling fast - without the tedious process of dressing individual wheels.This efficiency is reflected in an extremely lean pricing structure which will reduce your costs.
Furthermore, we believe we can make all your punches and dies, whatever size they may be, in high quality carbide at a lower cost than you currently pay out for hardened tool steel.
