MMS AUGUST 2018 138 IMTS 2018 Milling Machines Five-Axis Hybrid Machine Applies Hot-Wire AM Technique Mazak Corp.'s VC-500A/5X AM HWD multitasking machine is said to reduce lead times and part costs, increase machining accuracy and part quality, and improve productivity. The machine incorporates hot- wire laser deposition technology to combine additive processes and programmable welding automation with five-axis machining. An arc torch melts metal wire directly onto a base material or part, even if the two materials (wire and workpiece) are dissimilar. This enables shops to gener- ate precise sealing coatings along with near-net-shape part features or repair components such as impellers, turbine blades, and tool and die parts. The machine's laser cladding head has the same five-axis capability as its milling spindle, providing maneuverability. The platform suits high-volume additive manufacturing and helps to minimize equipment and material costs. The head also incorporates an automatic wire feeder system that feeds welding wire to an argon gas nozzle. The head provides a deposition rate of 3 to 4 lbs/hr and offers a 98-percent material utilization rate. The machine has a trunnion-style rotary/tilt table to process small parts. It also features a Mazatrol SmoothX CNC and MTConnect-compliant features to ease pro- gramming and decrease cycle time. The machine features a CAT-40, 12,000-rpm spindle facilitating the machining of all common metal mate- rials including steel, aluminum and cast iron. Optional speeds of 15,000 and 20,000 rpm are available to address a variety of part production requirements. A 30-tool storage magazine contributes to uninterrupted part machining. | Mazak Corp. | West, Level 3 & Annex, Booth 432000 Rigid Milling Machines Occupy Small Footprint The MCC series of milling machines from Burkhardt+ Weber offers cutting performance along with a small footprint, according to the company. The series is avail- able in sizes that support pallets as large as 1,000 × 1,000 mm (39.4" × 29.4") and payloads as heavy as 2,500 kg (5,500 lbs). With XYZ-axis travels measur- ing up to 1,400 × 1,200 × 1,600 m (55.1" × 47.2" × 63.0"), the largest model is 3500 mm (138") wide. The series is suitable for integration into automation sys- tems and offers accuracy, high stiffness and reliability. A range of spindles for four- and five-axis config- urations offer as much as 1,400 Nm and 41 kW (959 foot-pounds, 55 hp) of cut- ting performance and speeds as fast as 10,000 rpm. The five-axis model features a rigid, A-axis concept with a 30-kW (40-hp) motor spindle that has a large swivel range. Tool load capacity is 40 kg (88 lbs). It can employ cutting tools as long as 650 mm (25.6") without reducing swing size. Attachment heads can be clamped against the spindle nose by a precision head clamping system and loaded automatically via the company's toolchanger unit. The series is designed to be easy to link and is ready for digital networking in self-organizing production processes. Machines can be fully integrated into MES infrastructure. | Burkhardt+Weber LLC | South, Level 3, Booth 338656
