Project Description
A machine tool capable of:
- milling
- turning
- drilling
- grinding at 6000RPM
- belt sanding
- cutoff saw
machine should be constructed with
- hybrid weldment/Epoxy-concrete cast bases
- spindle with < .001in (25 microns) of runout
- spindle speed > 6000RPM
- modular liner rails from 6" - 50" (300mm - 1.25m) travel or more
- modular rails and spindle fit to bed with replication material sealant
- overarm for mounting arbors
- attachment points for bolting on a vertical milling head

Design Rationale
This project is an attempt to design a modular set of technologies that can be used for designing and building machine tools. Since no one machine design is the better then another, developing the methodology, tools and materials to easily build specialized tools gives much greater flexibility then a single static design.
technologies included are:
- linear rails
- high speed spindle
- ACME drive with anti-backlash nut
- replication material alignment
- Epoxy/Granite Filler for vibration dampening
- indexing head for gear cutting and radial parts
- rotary table for arcs and radii
- Digital Read Out (DRO)

spindle is a counter bored pipe with bearings and seals pressed in. The pipe housing is then mounted in the machine frame and made vertical to the world. long dovetail ways are aligned perpendicularly to the spindle and parallel to each other. once alignment is complete epoxy/granite is then mixed and applied to the frame increasing rigidity and weight. Opposing slide for the embedded dovetail is then assembled onto the embedded dovetail (slide | gibb | embedded slide | space | embedded slide| slide) cast in place.
