iQ300 ● iQ500

iQ300 and iQ500 Makino's vertical machining centers

Introduction

The iQ300 is the ideal precision micro milling machine for manufacturers of LED tooling, optic surface finishes and other high-tolerance machining applications. The machine delivers wide ranging capabilities from sub-micron machining accuracy and repeatability up to macro-scale machining applications. Built with a state-of-the-art linear motor design, 0.005-micron scale feedback and unparalleled component temperature control. Together, these features provide precise and predictable machining results, eliminating continuous process parameter adjustments due to tool positioning error and thermal distortion.

MACHINING SAMPLES

Mold base plate for lens (1 μm* center position error at maximum)

Moldbase_iq300

Material: Stainless steel (STAVAX, 52HRC)

Size (diameter x height): 100 x 10 mm

Roundness of each hole: 0.6μm or less

Machining time: 2 hr 36 min

*1 Actual value at Makino’s assembly plant.


Structural color by V-Groove gratings (0.5 – 0.7 μm pitch between V grooves)

*2 (3 colors) (Super fine V grooves machining by hale machining)

structuralcolor_iq300

Material: Non electrolytic Ni-P plaiting

Size (L × W × H): 30 × 30 × 10 mm

Tool used: Single-crystal diamond bite

single_iq300

*2 [Structural color]: Refers to the phenomenon of fine nano-structure coloring due to interference, refraction, diffraction, and scattering of light. In this case, the surface appears blue, yellow and red, due to V-grooves engraved in almost the same pitch intervals as the wavelength of the visible light from 500 to 800 nm.
