Capabilities

The high-productivity features of the new Haas EC-500 HMC include a 813 x 508 x 711 mm work cube, dual 500 mm pallets, 1-degree indexing, an 80-gallon coolant system and triple-auger chip removal.

The standard 8,000-rpm, 40-taper spindle is powered by the Haas 20-hp vector dual drive system; an optional 30-hp, 12K spindle is also available. Both spindles feature an inline, direct-drive system that couples the drive directly to the spindle. This results in less vibration, heat and noise than belt- or gear-driven systems - which means superior surface finishes, excellent thermal stability and quieter operation. A 40+1 side-mount tool changer and 12.7 m/min cutting feeds are also standard.

The servo-driven pallet changer on the EC-500 swaps pallets in just 9 seconds, and each 500 mm pallet has a load capacity of 454 kg. A separate load station allows the operator to safely load/unload parts or change fixtures on one pallet while parts are being machined on the other, keeping spindle run time at a maximum. A full 4th-axis rotary table is also available for shops requiring simultaneous 4-axis motion.

Haas Automation's VF-1 vertical machining centre has 508 x 406 x 508 mm xyz travels and is built using all American-made cast-iron components. Like every Haas machine, the VF-1 represents years of on-going refinement. Customer feedback coupled with the relentless pursuit of perfection sees advancements and design-enhancing changes incorporated directly into the production line every day.

The Haas VF-1 is a rugged, small-footprint VMC that yields reliability and accuracy in a small-framed machine. The VF-1 has a 40-taper cartridge spindle driven by a 20 hp vector Dual-Drive (Y-Delta) drive.

With a long list of standard features and high-productivity options, the Haas VF-1 is one of the best value machines available today.

 

 

The HL-2 is the latest Haas high-performance turning centre - designed to provide heavy cutting ability, extreme rigidity and high thermal stability. It has a maximum cutting capacity of 15" x 20.5" (381 x 521 mm), with maximum swings of 31.75" (806 mm) over the front apron and 20.75" (527 mm) over the cross slide. The standard 20 hp (14.9 kW) spindle yields 140 ft-lb (190 Nm) of torque at 2000 rpm, and spins to 4000 rpm. The A2-6 spindle nose is equipped with a 8.3" (210 mm) hydraulic 3-jaw chuck, and a 12-station bolt-on style tool turret is standard. High productivity options for the HL-2 include a belt-type chip conveyor, hydraulic tailstock, and automatic tool probe.

Laser Welding

 

 

Using a laser welding system together with a manually applied filler material it is possible to build up a surface or edge of an injection mould tool. This process can be applied to all commonly-used mould tool materials (including tool steels, stainless steels, copper alloys and aluminium). The laser provides very low heat input welding, which can be applied locally to rectify a worn or damaged area of the tool. Laser welding wires are fed by hand into the weld pool resulting in a very smooth and consistent application of material which can then be machined to the final geometry and polished. Our family of laser welders can repair any size of tool from the smallest insert to a complete multi-tonne mould.

 

Inspection

 

Each component must undergo some form of Inspection. The specification and criticality advised on the drawing will determine which type of Inspection is required to meet the Defence and Aerospace grade.
