Performance & Bundle Integration Features
- Integrated 2-Axis MN300 DRO Kit provides crisp digital tracking across 12" x 36" coordinates, reducing operator layout times and eliminating backlash calculations.
- Variable Speed X-Axis Power Feed delivers automated table travel from 1 to 32 inches per minute, optimizing chip loads and ensuring flawless surface finishes.
- 3 HP Variable Speed Spindle Head allows operators to tune tracking dynamically from a low 60 RPM for heavy-torque cutting up to 4,200 RPM for high-speed end milling.
- Precision Hardened & Ground Table & Ways are meticulously scraped to hold tight tolerances and offer smooth slide tracking across maximum cross and longitudinal travel paths.
- Three-Stage Automatic Spindle Downfeed channels exact power feed rates (.0015", .0030", and .0060" per revolution) to maximize repeatability during precise deep boring operations.
- Oversized 3-3/8" Chrome Quill Assembly combined with a premium R8 spindle taper minimizes tool flexion under heavy side-load milling stresses.
- Articulating Head and Ram Mechanics offer broad facility coverage, supporting compound 45-degree tilting and full 90-degree left/right axis swings.
