Used Acra's 22" x 16" x 16" Acra CNC (Swing Table) Production Center.
Description
A fast and precise vertical machining center with 180° auto pallet changer (swing table), high speed, and ultra-quick tool changer. Built on a rugged frame with quality craftsmanship, this machine is ideally suited for multiple part set up and high production of accurate milling, boring, and drill/tap operations. Accuracy, speed, and reliability are achieve by a combination of widely spaced and double anchored linear guide rails aboard ribbed Meehanite casting; direct coupled spindle motor, ultra-quick arm type tool changer; and single source and matched control, AC Servo and Spindle motors, and digital drives.
