KH-4500kai
KIWA eliminated all possible wasted space on the KH-4500kai Horizontal Machining Center. As a result, the KH-4500kai incorporates one of the largest work envelopes in its class.
KIWA maintains speed and agility, with more than 1G acceleration/deceleration on all axes. The rigidity is enhanced with “stepped” base and column casting design.
Keeping the traditions of KIWA design, the KH-4500kai is fully expandable, both for the APC and ATC portions of the machine. These features are field-installable.
