Nachi GMS450 Skiving Machining Center For Gears

Manufacturer: Nachi-fujikoshi corp
Model: GMS450

Outline

Super accurate high performance skiving at peak of ideals
High efficiency gear skiving reduces machining time to as much as 1/5 (compared to gear shaping)
Proprietary technologies used to add lathe and drill to skiving machine for a multi-functional gear shaper
Both mass production & multi-type-small-lot production
Compact yet can be machining up to 450mm diameter part
Hard-skiving achieves high-precision machining of hardened gears
Interactive operation screen provides excellent man-machine interface

Features

Reduces machining time to as much as 1/5 (compared to gear shaping)
Three jobs consolidated in one machine
Skiving machining center for Gears GMS450 achieves a high-efficiency gear skiving machine. Plus. it also has lathe and drill functions that integrate jobs in this skiving gear shaping machine.To achieve smart production lines by reducing floor space
Skiving machining center for Gears requires little space to improve gear production lines to be smart production lines that can handle a variety of production formats from multi-type small-lot production to high-volume production.
Proprietary technologies produce new design skiving machine
Upright machining center built with gantry-type column Skiving machine with table that rotates on B-axis
New spindle designed for skiving
All axes have V-rail slides
Super-rigid spindle equipped with large diameter bearing and high-torque direct drive motor
V-rail slides with superior rigidity and damping used on all sliding surfaces. including the tool spindle.
X axis and B axis equipped with table clamp mechanism
Superior workability and operabilitySimple changeover and loading & unloading of workpieces
Easy access to Jig
