Overview
The Amada TECHSTER 104 is the mid-range model in Amada’s TECHSTER series of CNC forming surface grinders, featuring a 1,000 x 400 mm standard chuck size for larger die blocks and tooling. It shares the ball screw with direct drive system for smooth backlash-free positioning on all three axes.
Axis travels span 1,200 mm (traverse) and 460 mm (cross), with a spindle center height of 750 mm -- significantly taller than the TECHSTER 84 at 500 mm, accommodating taller workpieces. The 7.5 kW (peak) / 4 kW (continuous) spindle drives the same 355 x 38-50 x 127 mm grinding wheels.
The larger table and longer traverse suit grinding progressive die plates, larger mold components, and precision parts exceeding the 800 mm capacity of the TECHSTER 84.
New TECHSTER 104 systems typically price between $150,000 and $250,000.
