Here’s how a typical MDF vacuum table works…
We’ve published a couple of articles on vacuum fixturing in the past and they’ve been among the most popular long term posts we’ve done.  It’s no wonder as vacuum fixturing can be extremely convenient to use.
With that in mind, we went to town researching two giant…

What Do Food Trucks, CNC, and Makers Have in Common? Hint: Ask Anthony Bourdain

Jun 7, 2016   //   by Bob Warfield   //   Beginner, Blog, Business, CNC Projects, Cool, Manufacturing, Techniques  //  2 Comments

Why should we be excited about Makers and Hobby CNC’ers?
I just saw this great quote from Anthony Bourdain on Food Trucks over on Scott Johnson’s blog, and it really hit home for me as a CNC’er and Small Business Entrepreneur:
“Why should you be excited about food trucks? Because they allow creative chefs […]…

Milling Composites, Part 3: PCD End Mill Support for G-Wizard Calculator

Apr 10, 2016   //   by Bob Warfield   //   Blog, FeedsSpeeds, Manufacturing, Products, Software  //  No Comments

PCD Tooling such as these Guhdo endmills can really increase tool life when machining composites.
In part 2 of our series on machining composites we saw that composites can be incredibly abrasive and therefore quite tough on tool life.  The most common way to get better tool life is to switch to PCD (poly-crystalline diamond)…

15 Most Useful Features in G-Wizard for Higher Material Removal Rates
