The DRL1200/600 are designed with air bearing spindles. Air bearing spindles are lower
priced, have lower operating costs, and lower error motions.
For small scale production
For R&D
The DRL1200 is built on Precitech’s open frame
machine base and is optimized for the drums for
small scale production applications.
The DRL600 is built on Precitech’s
common large frame machine base and
is optimized for R&D applications.
