The Walter Helicheck Plus CNC tool measuring machine for micro tools within the 0.1 mm to 200 mm diameter range.
Helicheck Plus is equipped with four fixed cameras for the non-contact and fully automatic measurement of tools and grinding wheels and, according to VDI/VDE 2617, achieves a measuring length deviation of E1 = (1.4 + L/300 mm) micron, where L equals measuring length.
Based on the use of a substantial granite block with excellent vibration damping, the fully enclosed machine features front, back and top light camera magnification of up to 400x for micro tools, and back light up to 50x for standard larger tools. The machine incorporates Diffusor ‘soft light’ illumination that avoids excessive reflection of the face/feature being measured, to aid inspection clarity.
