Unimat Lathe and Micro Milling machine rebuilds. I wasn't sure where to post this, so here it is.

Unimat Lathe and Micro Milling machine rebuilds.

I recently acquired a Unimat to replace the one I let get away several decades ago. It was so much fun I decided to get another. So, one will be a dedicated Micro Mill and one will be a lathe. The mill will be a stand alone unit, and also be able to reach the carriage on the lathe for more versatility. The first machine I got is one of the Zamak casting units. Boring Small Holes 3. Bars with HSS Tips.

Another method having interchangeable tips is one with a steel shank that holds a small piece of high speed steel at the end on which the cutting edge is ground. Whilst a very satisfactory method it will not work at very small diameters. Photograph 3 showing a commercial set, the smallest which works down to 8mm when the cutter is at 90° to the shank but as much as 10mm when at 45° and ground for machining a blind hole. The photograph shows there are four sizes in the set, though you may find it possible to purchase individual sizes. Paul's Fantastic Workbench!: A dividing head for the Unimat. Another usefull accessory, indexing tables or dividing heads are used when milling or drilling.

This should help. This section updated November 2010. Home Wiring Guide - Residual Current devices. A residual current device (RCD), or residual current circuit breaker (RCCB), is an electrical wiring device that disconnects a circuit whenever it detects that the electric current is not balanced between the phase ("hot") conductor and the neutral conductor.

Home Wiring Guide - Residual Current devices

Such an imbalance is sometimes caused by current leakage through the body of a person who is grounded and accidentally touching the energized part of the circuit. A lethal shock can result from these conditions; RCDs are designed to disconnect quickly enough to mitigate the harm caused by such shocks. How a rack cutter can produce gear teeth. Proper hobbing generates the involute gear shape essentially by putting the proto gear through every possible permutation of positions against a rack shaped cutter and cutting away all the bits that interfere.

How a rack cutter can produce gear teeth

The result is a perfect involute. For a lot of practical applications, we can use approximations to the involute and not notice much difference. Single point cutters may use circular arcs for example. How a rack cutter can produce gear teeth. Cutting gears with a simple hob.
