Have you ever considered a Z-Axis counterbalance for your CNC machine?
Most commercial VMC’s use one.  Here’s a Hurco VM1:

auxilliary high speed spindle

It’s fairly common to find machines that have multiple spindle options available.  I don’t mean that you can specify multiple, options, but that there are actual multiple options delivered with the machine.  A very simple example would be multiple pulley ratios.  More exotic would be sub-spindles, for example a high-speed auxiliary spindle or speeder on…

shopmade dial bore gage

One of the most accurate ways to measure a bore is with a dial bore gage, but these can be really expensive and seldom used tools.  A nice Mitutoyo dial bore gage set is almost $400 as I write this.

Dude, have you seen what these CNC machines cost?
CNC is one of my favorite things in the world, and it is amazing that an individual these days can actually have a full-blown CNC machine that’s more powerful than the machines used to put men on the moon right in their own garage.  Heck, they’re…

Build a Powerful Tramp Oil Skimmer for Your Coolant

Dec 22, 2016   //   by Bob Warfield   //   Blog, CNC Projects  //  7 Comments

Dang that coolant is stinky today!
Flood coolant is a fact of life for many CNC operations, even relatively small machines like the Tormach 1100 in my home shop.  Another fact of life is that if left to its own devices, coolant will accumulate impurities that can leave it very stinky–your nose literally doesn’t want…

Spinning Pocket Lint Fidgeters of Doom!
That’s sort of what this latest installment in my CNC gift idea series is about.  We started out with jewelry, moved to outdoor gifts, and for something really unusual.  The non-tactical EDC-thing is a nod to the idea that these are Everyday Carry Items, they just don’t have much…

VMC Auto Part Loader

I love automation–there’s just something about watching a robot making parts you’re going to sell.  A machinist friend of mine (Hi Peter T.!) refers to his bank of older Hardinge CNC Lathes as his money printing presses.  They sit there with their bar pullers grinding out parts for him to sell all day long and…

Nov 1, 2016   //   by Bob Warfield   //   Blog, CNC Projects, Cool  //  1 Comment

Tormach has built a wonderful business in the hobby and low-end CNC machine world.  Their machines are not the highest performance, but they’re bulletproof, economical, and easy to work on.  Tormach even says that while they don’t recommend it, their machines survive crashes handily, making them ideal for education, makerspaces, and beginners.  I’ve seen many…

CNC Lost Wax Casting

Look, it’s time.  Your friends all want to know what you’re going to make with that fancy CNC gear you’ve been tinkering with for months.  They’re not going to be satisfied if you simply tell them (as I often have), “I’m making more tools.”  It’s getting harder and harder to get new CNC-related purchases past…
