Hwacheon HIT-A400 VERTICAL MACHINING CENTER

Technical Description

The Hwacheon HIT-A400 is a compact vertical machining center engineered for high-speed precision manufacturing. Featuring a BBT-30 spindle with BIG-PLUS dual contact technology, this machine delivers maximum spindle speeds of 15,000 RPM (with a 12,000 RPM option), enabling aggressive material removal and rapid tool changes. The dual contact spindle system simultaneously engages the taper and flange face, providing superior tool rigidity and eliminating Z-axis movement during high-speed rotation. The 14-position automatic tool turret achieves rapid 0.30-second tool change times, minimizing non-cutting intervals and maximizing productivity. The machine accommodates workpieces up to 440 lbs on its 23.6" x 15.7" table. Three-axis CNC control delivers impressive rapid traverse rates across all axes at 2,358 ipm (60 m/min), with X, Y, and Z travels of 20.47", 15.7", and 11.8" respectively. Available spindle power options of 8.60 HP (standard) and 10.00 HP provide flexibility for varying application requirements. The direct spindle connection ensures stable rigid tapping performance even with small taps, while ceramic bearings minimize thermal displacement for consistent machining precision. This configuration makes the HIT-A400 ideal for medium to large batch production runs requiring efficient, repeatable accuracy in drilling, tapping, and general milling operations.
