Tormach Fab Lab: Haimer 3D Sensors

After a bit of time off, we're getting back into the swing of things on the blog.  Today's video topic is in response to several recent questions we've fielded recently about a very useful gauge: the Haimer 3D Sensor. For those unfamiliar, Haimer 3D sensors can be used to quickly and accurately find milling work offsets in X, Y and Z.   When properly setup, these will exceed the accuracy of most other edge finding techniques available to the small shop machinist. Here are two things to keep in mind:

Tormach Fab Lab: How to use a Companion Horizontal Spindle

  You can set up a companion spindle with our Horizontal Spindle Arm Mount for milling in the XZ (G18) or YZ (G19) plane.  This can be a great technique for doing light milling on the end of a very long workpiece.  In this episode of Tormach Fab Lab, Mike C. demonstrates how to get this setup right.   [youtube]http://youtu.be/0oBlsirN4t8[/youtube]   You can now also model this setup in SprutCAM by taking advantage of the brand new Tormach PCNC machine definitions in SputCAM 8.  Here's a video that shows how to get that started as well.   [youtube]http://youtu.be/r8l99stgL8s[/youtube]   Want to try this out for yourself?  We've got the Kress High Speed Spindle and all of the mounting clamps and brackets for sale here: Tormach eStore - Companion Spindles More Tormach Fab Lab Videos:

Tormach Fab Lab: Using a 2-Jaw Chuck

Although not nearly as common as 3- or 4- Jaw chucks, a 2-Jaw Chuck can be quite handy for certain 4th Axis jobs. The jaws on a 2-Jaw chuck are opposite each other (obviously!) and they are driven by a scroll plate, just like the jaws on a 3-Jaw chuck. They are typically used in 2 scenarios:
