Gleason Phoenix 280G Bevel Gear Grinding Machine

The Gleason Phoenix 280G is a bevel gear grinding machine for workpieces up to 280 mm in diameter. Gleason publishes three capacity figures for it: that 280 mm maximum workpiece diameter, a range of tooth numbers from 1 to 300, and a maximum wheel diameter of 9 in.

Diameter is the limit that decides whether a job fits. With tooth numbers running from 1 to 300, tooth count will rarely be the reason a gear is turned away. A ring gear more than 280 mm across is. In a bevel pair the ring gear is the bigger part, so size the machine against the ring gear and the pinion follows.

The 9 in wheel limit deserves the same attention. A bevel gear is normally ground with a wheel matched to the cutter diameter the tooth form was designed around, so a design based on a cutter larger than 9 in is outside what this machine can finish even when the blank itself is under 280 mm. Check the design cutter diameter of each part family before assuming the workpiece figure tells the whole story.

Gleason's table for this model stops at those rows. The workpiece limit is given in millimetres and the wheel limit in inches, and both are quoted here as published. Spindle power, machine weight, floor space and control details are not in the table, so request them from Gleason before drawing up a foundation or electrical plan.
