How much does the Gleason 80PS cost?
Price estimate
We do not have a price for the Gleason 80PS that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Gleason 80PS is a compact gear cutting machine for small-module work: external gears up to 80 mm (3.1 in) in diameter, internal gears with a tip diameter up to 120 mm (4.7 in), and a maximum module of 1.5 mm. It cuts both internal and external gears, and Gleason lists a hobbing changeover time of less than 2 minutes.
Three diameters define the envelope and they are not interchangeable. The 80 mm (3.1 in) figure is the limit for external teeth. For internal gears the tooth tip diameter can reach 120 mm (4.7 in), while the part itself can swing up to 150 mm (5.9 in). A ring gear drawing therefore has to be checked twice, once for its internal teeth and once for its outside body.
The 1.5 mm module ceiling places the machine in fine-pitch territory. Teeth coarser than that are outside the listed range however small the blank is.
The changeover figure matters for shops that run different part types through one machine. With less than 2 minutes listed for the hobbing changeover, switching process within a shift is practical instead of something saved for a batch change. Spindle speeds, face width and machine weight are not in the table and need to come from a quotation.

Strengths & Limitations
Strengths
- Cuts internal and external gears on one machine
- Internal gears up to 120 mm (4.7 in) tip diameter inside a 150 mm (5.9 in) swing, larger than the 80 mm (3.1 in) external limit
- Hobbing changeover time is listed as less than 2 minutes
Limitations
- Maximum module is 1.5 mm, so anything coarser is out of range
- External gears are limited to 80 mm (3.1 in) in diameter
- The table gives no face width, spindle speed or machine weight

Frequently Asked Questions
01
External gears can be up to 80 mm (3.1 in) in diameter. Internal gears can have a tip diameter up to 120 mm (4.7 in). The internal swing diameter of 150 mm (5.9 in) is the largest body that can rotate in the machine when an internal gear is cut.
02
Gleason lists a maximum module of 1.5 mm and gives no minimum in the table. That makes it a fine-pitch machine: a gear with coarser teeth is out of range even if its diameter is well inside the 80 mm (3.1 in) external limit.
03
Less than 2 minutes, according to Gleason's figure. For a shop that alternates between part types during a shift, that keeps the changeover short enough to follow demand instead of grouping work into long batches.
