Manual Precision Surface Grinders
Freeport 618 surface grinder
These Freeport small precision surface grinders are manual feed, but the similar SGS-816 series does have hydraulic feed versions. They have ball bearing inserted steel slideways for near friction free action from left to right.  The cross slide ways are double V's to ensure high stability. The main structure is entirely of cast meehanite.
