The collet taper is R8.
User Certification
We do Mill and Lathe certification on an as needed basis. Email the warden to request certification. Only the following people are permitted to certify you on the mill:
Certification Goals – Don’t hurt yourself. Don’t hurt the machine.
- Mill safety and setup
- Tool selection for milling operations
- Holding parts using the machinist vice and parallels
- Change tools and set spindle speeds
- “Zero” the X, Y and Z axis using the DRO
- Perform basic facing cuts on steel
- Mount and secure work using parallels and hold downs
- Demonstrate understanding of Backlash
In preparation for certification please; Read the manufacturers manual and study the excellent materials from Case Western

Take the milling quiz.

Current Status
A defect was identified with the Pinion Assembly (enco part number 6116-6S) via borescope on 2/22/2015. Ian and Ryan identified the busticated part.
Endmills
The endmills are the cutting tools for the milling machine. Wikipedia has a page for these as well.
Hive owns a variety of high speed steel end mills which were purchased used on eBay. They are under the mill labeled 'Good enough'
