How much does the Mitsubishi GA26 CNC Gear Hobbing Machine cost?
Estimated price range
Our best estimate for a cnc gear cutting machine in this class — not a quote from Nidec Machine Tool. Configuration moves it a long way.
Overview
The Mitsubishi GA26 is a CNC gear hobbing machine for gears up to 260 mm (10.2 in) in diameter, with a maximum module of 4 and a maximum face width of 200 mm (7.9 in). It is not in Nidec Machine Tool's current lineup, so the listed figures matter mainly to someone assessing a used machine and should be confirmed against that machine's own documentation.
The listed figures point at fast, dry cutting. The hob spindle is direct drive with speeds up to 5,000 RPM, the workpiece turns at up to 1,200 RPM, and dry hobbing is listed as standard. Workpiece speed is the figure that limits a hobber on pinions with few teeth, because the work has to turn a larger part of a revolution for every turn of the hob. A table that reaches 1,200 RPM leaves room to run small hobs fast on that kind of part.
Module 4 is the ceiling, so coarse-pitch gears are out of range whatever their diameter. Within it, 200 mm (7.9 in) of face width leaves room for wide gears or for several narrow blanks stacked on one arbor.
Six CNC axes are listed, and gear quality is given as DIN 5 (ISO Grade 5). Read that grade as what the machine was built to reach. What a particular used machine holds can only be shown by cutting a test gear and measuring it. A CNC control is listed, but the listed figures say nothing about the hobbing cycles on it, the hob size or the axis travels.

Strengths & Limitations
Strengths
- Direct-drive hob spindle listed at up to 5,000 RPM, suited to small-diameter hobs run at high cutting speeds
- Workpiece speed up to 1,200 RPM, so low-tooth-count pinions do not hold the hob speed down
- Dry hobbing is listed as standard, not as an option
- Gear quality is listed as DIN 5 (ISO Grade 5) on a machine with 6 CNC axes
Limitations
- Maximum module is 4, which rules out coarse-pitch gears even when they fit the 260 mm (10.2 in) diameter limit
- Not in Nidec Machine Tool's current lineup; the listed figures should be confirmed on the actual machine
- The listed figures give no hob size, axis travels, spindle power or machine weight, all of which decide tooling and installation

Frequently Asked Questions
01
The listed figures give a maximum workpiece diameter of 260 mm (10.2 in), a maximum module of 4 and a maximum face width of 200 mm (7.9 in). All three limits apply together: a gear inside the diameter limit is still out of range if its module is above 4.
02
Yes, the dry hobbing row reads standard. Dry cutting puts all the heat into the chips and the hob, so the condition of the hob coating and of the chip evacuation on a used machine deserves a close look.
03
Hob speed is listed as up to 5,000 RPM on a direct-drive hob spindle, and workpiece speed as up to 1,200 RPM. The two are linked by the tooth count of the gear, so the workpiece limit is the one that matters on pinions with few teeth.
04
The listed figures leave out hob dimensions, axis travels, power and weight, so get those from the machine's manual. The listed gear quality of DIN 5 (ISO Grade 5) should be proved with a test gear cut on the machine and measured, since nothing else shows what the machine holds today.
