3M Ion Beam Raster / Gate Controller, Pulse Gating + Beam Deflection, Rack Mount
$299

Ion beam controllers are specialized precision instruments used in semiconductor manufacturing, materials research, and ion implantation processes. These devices manage beam deflection and gating functions - critical capabilities for directing and timing energetic ion streams with microsecond-level precision. The raster functionality allows beam positioning across target surfaces, while pulse gating controls on-off timing. Equipment in this category demands technical expertise to operate and validate; successful integration requires understanding your process parameters and measurement capabilities.

This unit is untested and in condition 9.3 - it's a find for someone with the knowledge and equipment to bring it into service. For labs, research facilities, or manufacturing operations that work with ion beam systems, having spare or backup controllers on hand represents meaningful cost savings versus new equipment.

Mazak Megaturn Nexus 900 CNC Vertical Turning Center - 36" Chuck, 39.37" Swing
$149,000

CNC vertical turning centers are production workhorses in job shops, contract manufacturers, and heavy fabrication operations. These machines excel at high-precision turning work on parts requiring complex multi-axis operations, tool changes, and repeatable accuracy. The 12-station turret design means faster cycle times and fewer manual interventions - critical for shops managing tight tolerances and steady volume. Mazak's Mazatrol control platform is recognized for intuitive programming and reliability in demanding environments. Used equipment like this offers established shops a way to expand capacity or replace aged machinery without the capital outlay of new.

This unit carries 23,803 hours from 2013 and was powered up in our shop where it appears to be functional. The 36" chuck accommodates substantial workpieces; the 31.50" turning height and 36.22" turning diameter define the envelope for the parts you can produce. Mazak machines in this class hold their value and performance well when maintained.
