Overview

The Gleason P-Series 300 is a CNC gear hobbing machine designed for the high-precision production of external and internal cylindrical gears, splines, worms, and sprockets with workpiece diameters up to 300 mm. Targeted at automotive transmission, electric vehicle drivetrain, and general power transmission component manufacturers, the P-Series 300 combines a compact footprint with high-speed cutting capability and full integration into Gleason's digital manufacturing ecosystem.

The P-Series architecture features a thermally symmetrical machine structure with hydrostatic guideways on the key linear axes to eliminate stick-slip and deliver sub-micron positioning repeatability. The direct-drive hob spindle supports climb and conventional hobbing at cutting speeds up to 600 m/min, accommodating both coated carbide and HSS hobs across a wide range of modules. Gleason's Active Vibration Control (AVC) technology continuously monitors and damps structural vibration, extending tool life and improving surface finish on demanding materials including hardened steel and case-hardened alloys.

The machine's workholding system accepts a wide range of arbors, chucks, and expanding mandrels, and the integrated part-handling interface supports automated loading by robot or gantry loader. The Gleason SmartMES control interface provides real-time process monitoring, tool wear tracking, and SPC data export, enabling Industry 4.0 connectivity with factory MES/ERP systems. Automatic hob shift and axial shift cycles extend hob life and reduce tool cost per part.

The P-Series 300 is part of Gleason's broader P-Series platform, which spans multiple work envelope sizes and shares common software and tooling interfaces across the family. Its combination of precision, speed, and digital integration makes it a strong choice for automotive suppliers and gear job shops requiring consistent quality at production volumes.

Frequently Asked Questions

01 Can the Gleason P-Series 300 cut internal gears?

Yes. With the appropriate internal hobbing attachment and arbor tooling, the P-Series 300 can produce internal cylindrical gears and splines within its work envelope limits.

02 What hob types are compatible with the P-Series 300?

The P-Series 300 accepts both solid carbide and HSS hobs in standard and long-series lengths. Gleason's automatic hob shift cycles optimize wear distribution across the full hob length.

03 Does the P-Series 300 support dry hobbing?

Yes. The P-Series 300 is designed to support dry hobbing with coated carbide hobs, which eliminates coolant disposal costs and is preferred for automotive production environments.
