Gear Generation

Hobbing Large Diameter Gears
The H 400 is capable of running small lots or mass producing straight and helical gears; crowned and tapered gears; worm gears; chain sprockets and toothed belt discs; cluster gears; and special profiles. The H 400 can use standard hob or form milling technology, ranging from dry or wet machining, with high capacity HSS or carbide tools to skive hobbing of heat-treated gears.

Also on display will be single-flute gundrill machines, multiple diameter carbide drills and reamers, the Star PTG-6L tool and cutter grinder, and gear cutting tool solutions.

Turning Alternatives
Precision electro-chemical machining technology (PECM) presents a production process that opens up completely new fields of application. PECM is a process for the machining of high-alloyed materials, such as nickel- and titanium-based alloys. All electro-chemical machining processes are characterized by stress-free material removal, smooth transition points, and surfaces without ridge formations.

TableTop Tool Sharpening Machines
The TT6-36 tabletop and TT-SP6-24 tabletop special broaching machines are available in a 38" x 44" footprint. Featuring a 20" x 20" tabletop size, both machines move at a 5fpm to 30fpm. Both the TT6-36 and TT-SP6-24 are capable of broaching keyways, internal splines, and various other part forms. The CNC Automatic Broach Tool Sharpening Machine can sharpen helical or standard gullet, flat, or specially shaped broach tools up to 12" in diameter and 120" long.

Sawing, Machining Center
The ACS + CFMcurve integrated sawing and machining center, features a proprietary sawing algorithm with a servo motor-controlled feed to continuously adjust critical sawing parameters during each cut. The CFMcurve machining center simultaneously machines each workpiece end using 12 independent servo-controlled axes. Machining options include: threading, boring, profile turning, grooving, radius edges, and angled chamfering. Bundles of mill length stock, up to 16.5m long, are placed in an automatic loader, individually separated, and fed to the sawing process.

Indexing Table with Direct-Drive Work Spindle
The KX 500 FLEX incorporates a direct-drive work spindle, tailstock support, and dressing spindles. The ZX 1000, the big brother of the KX 500 FLEX, shares common machine elements and software with the KX 500. The large ductile iron bed and torque motor for high-load capacity allows high-speed grinding of frac bull gears with a dressable worm tool.

Profile Grinding
Design of the Liebherr LFG series profile grinding machines are for profile grinding of external and internal gears. The series includes three models for workpiece diameters from 800mm to 1,250mm. The LFG 1000 is for workpieces up to 1,000mm diameter will be shown at IMTS. The direct-drive table with swivel axis allows high-production grinding of topologically-correct, or topologically-modified tooth profiles, single- or double-flanked. In the standard LFG model, dressing of the grinding disc is accomplished by a single dresser combined with the shift and swivel axis.
