Makino is the originator of high-speed spindles for commercial use. With spindles able to achieve speeds of 20,000 rpm and above, it’s no wonder we are the undisputed leader in high-speed high-efficiency machining center technology. Makino machines will deliver precise statistical performance and dramatically reduced cycle times.
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.
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)
Material: Non electrolytic Ni-P plaiting
Size (L × W × H): 30 × 30 × 10 mm
Tool used: Single-crystal diamond bite
*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.

Size (L × W × H): 13 × 13 × 20 mm
Roundness of each hole: 0.6μm or less
Machining time: 8 hr 35 min
Mirror finish with PCD* tools
[Surface finish] Ra 20.7 nm
Grinding finish on the lateral face
