Used 62" x 31" x 27" Acra Vertical Box Ways Machining Center

Listing description

Acra's heavy duty 4 box ways Vertical Machining Center has a large capacity and is packed with features such as:

° Floating tool knocking (BT-50).
° Major casting parts are box-type in structure for outstanding rigidity and stability.
° The standardly equipped heat exchanger features excellent heat dissipation that reduces the
possibility of trouble and extends the service life of the electronic components.
° A laser unit, ball bar tester and spindle dynamic balance tester are employed to ensure high precision,
superior dynamic and static accuracy and machining quality.
° Chip flushing pieces on both sides combined with a screw chip conveyor, allow chips to be delivered
to the front chip tank.
° Uniform lubrication points on the slideways. A volumetric oil distributor is employed for uniform
lubrication on all slideways.
° Digital drives ensure high dynamic accuracy
° Three axis transmission adopts C3 class high precision double nut pre-loaded ball screws.
° An ergonomic extra-large worktable is designed with minimum distance to the ground as well as to
the operator.
° Slideways are coated with high quality Teflon and are precision scraped for outstanding machine
accuracy.
° Chip augers provided at both sides of the base are combined with powerful chip flushing devices to
deliver chips to the front mounted chip conveyor. This keeps the machine clean at all times.
