Mag puts a new angle on HMC spindles

The high-torque, 80-kW spindle is especially suited for aerospace titanium cutting, says Mag.

Mag says it followed the voice of the customer for input into the design of its modular HMC 1250 Series with a new 180,000-position A-axis tilt spindle for five-axis horizontal machining on large parts. The new 6000-rpm 46-kW tilt spindle joins an all-around 10,000-rpm 56-kW spindle, a high-speed 24,000-rpm spindle, a high-torque 2600-N•m spindle, and two live spindles (110- or 130-mm diameter) as headstock options.

The high-torque 80-kW spindle is especially suited for aerospace titanium cutting, the company says, while the live spindles extend W-axis reach by up to 800 mm, enabling deep-cavity milling to high precision with shorter, more rigid tool lengths. Standard on the live spindle, MAG's exclusive Z-axis thermal-compensation software dynamically offsets spindle growth to maintain tight tolerances.

The HMC 1250 Series is engineered for high-precision, high-productivity machining of large aerospace, power-generation, pump, valve, and off-road equipment parts. Major machine components, including the X-bed, Z-bed, and column are cast ductile iron, with 1250 x 1600 mm pallets, headstock, and rotary table housings of gray cast iron. A modular design provides a range of machine travels, 60- to 120-tool magazines, and two control choices, in addition to five spindle options, plus tilt capability. That application flexibility combines with maximum 3000-mm work zone swing range, 2050-mm work height capacity, and 7000-kg work load.

The machine offers 56 to 80 kW spindle power, 35 kN Z-axis thrust, and super-rigid, full-contouring hydrostatic rotary table. Productivity is enhanced with 40-m/min rapid traverse/feed rate and 15-s tool change (for up to 35-kg tools) to maximize in-cut productivity.

A standard 360,000-position contouring table enables precision four-axis machining of a variety of part geometries. The hydrostatic table provides a rigid machine platform, while a rugged worm gear drive with clamp securely holds axis position.

Meeting industry needs for tighter part tolerances and greater machining accuracies, the HMC Series comes standard with linear-scale feedback in X, Y, and Z axes, providing 8-micron positioning accuracy and 5-micron repeatability. Heavy-duty hardened and ground roller guide ways enable higher rapid traverse and acceleration/deceleration rates with double the load capacity and nearly 10 times the wear life of ball-type ways.

Researchers from Purdue University are studying the fundamental mechanisms behind a method that uses electrical fields to enhance ceramics-sintering processing, which could aid R&D of rechargeable lithium-ion batteries and fuel cells. The research also could shed light on a phenomenon called electromigration, which can affect the performance of electronic devices.

France's Dassault Aviation and India's Reliance Group announced in late September 2016 the creation of a joint venture (JV) in India called Dassault Reliance Aerospace. With this announcement came news that the Dassault Reliance Aerospace JV will be a key player in the execution of offset obligations as a part of the 36 Rafale fighter jet purchase agreement that was signed between France and India on September 23, 2016 and is valued at around €7.87 billion, or about Rs. 59,000 crore.

One of the biggest issues in bringing forward new designs is the length of time that it takes to agree to a new specification, research and evaluate the alternative features and configurations, and then embark on a development program that will take the design to flight testing and ultimately operational service.
