This horizontal machining center features the largest pallet available in the popular 1-Series line and provides unparalleled productivity and reliability to help manufacturers reduce costs from their operations.
The a81 horizontal machining center (HMC) from from Makino (Mason, OH) is loaded with features that help manufacturers increase productivity and decrease operational costs, including swift axis movement and faster spindle acceleration/deceleration than other comparable HMCs.
Out-of-cut time is diminished because of the machine’s standard ring-type, 40-tool magazine with short seek times. This is complemented by a quick automatic tool changer that has a fast tool-to-tool (1.7 seconds) time and chip-to-chip (3.5 seconds) time.
The a81 is the largest of the 1-Series line and is capable of handling a payload of 2,640 lb (1,200 kg) with an X-, Y-, Z-axis travel of 35.4 in x 31.5 in x 40.2 in (900 mm x 800 mm x 1020 mm). The machine is capable of simultaneous B-axis movement with tool change.
It is fitted with a 24.8 in (630 mm) pallet and a standard 50 taper, 10,000 rpm spindle with exceptional acceleration characteristics and minimal vibration. The spindle is equipped with a 300 psi through-spindle coolant system. Rapid traverse and cutting feedrate of the a81 are 1,968 ipm (50 m/min).
The machine footprint is 138 in x 215 in (3,460 mm x 5,370 mm), which is more compact than competitive machines and designed for easy maintenance access around the entire perimeter. High-volume chip evacuation is facilitated by a wide-center trough with a standard rear discharge lift up chip conveyor that includes a coolant leakage protection design.
Other features include an automatic pallet changer with safety guard, a standard three-point support system, an ergonomic swing operator control panel, a safety-designed four-layer protective operator door window and flood coolant and overhead shower coolant.
The a81 comes standard with proprietary, next generation Geometric Intelligence (GI) servo control with Radical Mode. GI helps provide the lowest cycle times achievable, while maintaining accuracy and meeting the customer’s Cpk requirements.
