Fives Debuts New Machining Center With Five-Axis Tilt Head
Fives’ new Giddings & Lewis HMC 1250 with Liné Machines’ five-axis tilt head provides a flexible, modular horizontal machining center for metal and composite machining.
Fives says its new Giddings & Lewis HMC 1250 with Liné Machines’ five-axis tilt head provides the most flexible horizontal machining center solution on the market. This combination brings together Liné Machines’ high-speed tilt head technology used in its high-performance gantry machines and the consistency of the Giddings & Lewis Horizontal Machining Center.
Fives says this combination delivers adaptable configurations across a wide range of applications. The company provides options for both a 27,000 rpm HSK63 spindle for high-speed machining of aluminum and a 15,000 rpm HSK100 spindle for more general-purpose machining of hard and soft materials, while also providing options for machining titanium and composites.
The machine build offers x-axis travel of 2,100 mm (82.7"); z-axis column travel of 2,350 mm (92.5") on the tilt spindle; y-axis headstock travel of 1,800 mm (70.9") on the tilt spindle; a-axis spindle tilt travel of 120 degrees; and a built-in contouring rotary table with a programmable mechanical clamp, 360,000 index positions in .001-degree increments and a rotary b-axis feed of 0-6 rpm. Also included is an automatic chain-type tool changer with 120 tool pockets and a max tool weight of 25 kg (55.1 lbs), process monitoring, probing systems and a high-pressure coolant system with basic components such as dual-chip conveyors and a full-enclosure must collection.
Fives promises that almost every aspect of this machine is configurable to suit the application. The company offers numerous choices for spindles, head travels, tool changers, coolant systems, control options and other tools to suit usage needs.
When this aerospace job shop settled on machining tungsten alloys and other heavy metals as its specialty, it had to have a machine tool, cutting tools, workholding and process know-how to succeed.
Fast CNC processing and high-pressure coolant contribute to removing metal at dramatic rates. But what should a shop know about cutting tools in high speed machining?
Cryogenic machining achieves dramatic tool life gains not by flooding the cut, but by refrigerating the tool.
