Makino Introduces a40 Horizontal Machining Center, Purpose Built for Fast, Reliable Die Cast Parts Production
MASON, Ohio -- Makino introduces the a40, the first and only horizontal machining center purpose-built for non-ferrous die-cast parts machining. Until now, machine tool selection for the die cast market has been limited to general-purpose horizontals that possess unnecessary capabilities and result in extended cycle times in the machining of near net shape die cast parts. The a40 addresses the unique needs of the die cast market by enhancing machine attributes most critical to improving productivity and per-piece costs in the machining of near net shape die-cast aluminum parts.
"Die cast manufacturers are under intense pricing pressure with mandatory cost reductions from OEMs and increasing global competition. The keys to overcoming these challenges lie in the reduction of machining cycle time and elimination of unplanned down time," said David Ward, horizontal product line manager for Makino. "To address the cycle time issue, Makino has re-evaluated each of the major castings using an Intelligent R.O.I [Reduction of Inertia design philosophy. The new design provides superior linear and radial agility and acceleration."
With the introduction of the a40, die cast manufacturers now have a machine that is designed specifically with their production goals in mind. The machine's ability to reduce part machining cycle time not only cuts down on per-piece cost, but also has far-reaching savings affecting capital investment, labor, floor space, utility consumption and durable tooling.
The a40 offers a 400-mm pallet with a workpiece capacity of 630 mm (24.8 inches) in diameter by 900 mm (35.4 inches) tall, making it an ideal platform for die cast parts commonly machined in the automotive and consumer product industries. Axis travels of the machine are 560 mm (22.0 inches), 640 mm (25.2 inches) and 640 mm (25.2 inches) in the X, Y and Z planes, respectively. Maximum payload is 400 kg (880 lbs). The a40 also offers numerous features and capabilities for improved utilization and reductions in non-cut time, including a 40-position automatic tool changer and an automatic pallet change system to ensure uninterrupted operation.
Makino's Intelligent R.O.I. Design
Makino's Intelligent R.O.I. (Reduction of Inertia) design is a collection of innovative technologies designed to slash un-productive non-cut times from part processes. Through this unique design strategy the a40 is able to provide:
Responsive CAT40 spindle acceleration to 12,000 rpm in 0.5 seconds.
Quick completion of common tapping operations with 6,000-rpm rigid tapping synchronization speed.
An average of 29% faster time to full rapid traverse rate, minimizing common feature to feature positioning time.
Optimal acceleration performance of multiple machine systems with evaluation of fixture and tool weights through Inertia Active Control (IAC) technology.
Proven Reliability
Unplanned down time is devastating to high-volume die cast production machining. As such, the reliability of the machining system is paramount. The a40 utilizes several of the robust, proven systems from Makino's 1-Series horizontal machining centers. Systems like single-piece X- and Z-axis covers, center trough chip and coolant management and dual supported ATC mechanisms provide exceptional reliability throughout the life of the machine. The a40 leverages these proven technologies, but then advances reliability with a host of new systems:
Standard Vision type broken tool detection supports unattended operation by quickly validating the condition of the cutting tools after each tool change.
Dedicated tool taper cleaning nozzles wash the tool taper with 20ì filtered coolant with each tool change, ensuring contamination free tool clamping.
Three stage coolant filtration with 20ì hydro-cyclone, eliminates coolant tank sludge common with aluminum machining, extending time between coolant system PM or cleaning.
