Overview
The Amada GLS 150GL is a CNC optical profile grinder built for precision grinding of complex profiles on punch, die, and tooling components. The GL designation indicates the enhanced model in Amada’s GLS series, featuring 4-axis NC control with simultaneous 2-axis interpolation for smooth, accurate contour following.
The GLS 150GL operates with a reciprocating slide stroke of 0-155 mm and reciprocation speeds from 30 to 400 min-1. The wheel spindle runs from 1,000 to 6,000 min-1, accepting grinding wheels from 120-180 mm diameter (3-10 mm wide, 31.75 mm bore). Radial relief angle spans -2 to 20 degrees with axial relief of ±15 degrees, allowing direct grinding of clearance angles on tooling components.
The 4-axis NC control handles complex profiles that would require skilled manual operation on conventional optical profile grinders. The GLS 150GL is positioned between Amada’s DPG series and the larger MEISTER line. New systems typically price between $180,000 and $300,000.

Strengths & Limitations
Strengths
- 4-axis NC control with simultaneous 2-axis interpolation for smooth accurate contours
- Wide reciprocation speed range (30-400 min-1) for roughing through ultra-fine finishing
- Radial relief -2 to 20 deg enables direct clearance angle grinding without secondary operations
- Spindle speed 1,000-6,000 RPM accommodates various wheel types
- Decades of Amada optical profile grinding expertise
- Compact footprint suitable for smaller tool rooms
Limitations
- Limited simultaneous axis control (2 of 4 axes) vs full 5-axis tool grinders
- Max 6,000 RPM is modest vs high-speed grinders at 10,000+ RPM
- Specialized application limits utility outside tooling work
- Amada Machinery America has smaller North American service footprint
