CNC Vertical Hobbing Machine optimizes dry machining.

Press Release Summary:

Based on single-piece frame cast from polymer composite material, Genesis(TM) 130H can be installed and re-located with no special lifting equipment. Direct-drive spindle motors eliminate need for mechanical adjustments, while cam-driven double gripper loader enables part load/unload times of 2 sec. Work area is isolated from machine frame to minimize thermal expansion from contact with hot chips. Stainless steel cutting chamber with steep inclination ensures that chips fall clear of work area.

Original Press Release:


Rochester, New York, February 16, 2006-- Gleason's new Genesis(TM) 130H CNC Vertical Hobbing Machine features a revolutionary new design that optimizes dry machining, significantly reduces floor space requirements and greatly improves cycle times.

The 130H Hobber is the first in a new family of gear production equipment from Gleason called Genesis(TM). All of the Genesis machines share a common platform: a single-piece frame cast from an advanced polymer composite material, which can be made faster, more accurately and with inherently more rigidity than conventional cast-iron assemblies. This common platform design also ensures a small, compact machine footprint and enables the user to install and re-locate the machine with no special lifting equipment or special foundations.

While the 130H Hobber can accommodate wet cutting processes, it is particularly well-suited for dry machining. The work area is completely isolated from the machine frame to minimize thermal expansion from contact with hot chips, and a stainless steel cutting chamber with steep inclination ensures that chips fall completely clear of the work area.

The 130H Hobber is equipped with an innovative new mechanical cam-driven double gripper loader fully integrated into the machine. As a result, costly non-productive time can be cut to a minimum, with part load/unload times as short as two seconds.

Unlike conventional hobbing machines, the Genesis 130H utilizes a new, patent-pending hob drive system to eliminate complicated mechanical and hydraulic clamping systems. Instead a simple "D-Drive" system enables the spindle to transmit more torque, with less runout, and at the same time accommodate the use of larger diameter hobs for greater performance and longer tool life.

The 130H also features direct-drive spindle motors, which further reduces setup and machining times by eliminating the need for mechanical adjustments and change gears. Higher acceleration/deceleration rates and increased torque, combined with faster axis motions reduce non-cutting time between cycles and increase overall productivity during machining.

Other significant features include:

o An Easy Access Service Module that consolidates hydraulics, lubrication and pneumatics into one location.

o Optional on-board chamfering and deburring capability.

o Availability of the latest SIEMENS or FANUC controls and the latest Gleason software running in a true Windows® environment.

o The chip conveyor may be located from either the side or rear of the machine to meet any cell/system arrangement.
