Our milling machine is manufactured by Sieg Industrial Group. It was sold in the United States by LittleMachineShop.com. The User's Guide is available here.
The dials on our milling machine are in metric. One rotation of the hand wheels moves the appropriate axis 1.5 mm. With 75 dial divisions this means each dial division is 0.02 mm.
Our milling machine has an R8 taper. A flat-faced 3/4" collet is available, allowing the use of the Tormach TTS tool system. We strongly suggest you purchase your own TTS chucks and maintain your own tools. ER32 collet chucks cover a relatively large range, are nearly universal and can be had on Ebay inexpensively. ER16 collet chucks more closely match the power capability of the machine. They can similarly be found on Ebay inexpensively. While the chucks themselves aren't much less expensive, ER16 collets are less expensive than ER32.
