Summary

The Makino UPN 01 is an ultra-precision wire electrical discharge machine (EDM) designed for fine, micro-scale cutting operations with extremely tight tolerances. Its core function is non-contact material removal using a small-diameter wire electrode and controlled electric discharge, delivering sub-micron accuracy and surface finishes as low as 0.02µm Ra. Differentiating features include a horizontal wire drive system, oil dielectric for superior spark gap control, pneumatic static pressure guideways, linear motor drives, and an integrated ultra-high precision rotary C-axis for advanced unattended operation.

Key Capabilities

• Sub-micron accuracy enabled by linear motors and pneumatic static pressure guideways
• Programmable increments as small as 0.1µm, with mechanical roundness of 0.2µm
• Wire operation from 0.100mm to 0.015mm in diameter; supports start hole threading from 30µm
• Achieves surface finishes down to 0.02µm Ra
• Oil dielectric for enhanced part accuracy, surface quality, and metallurgical control
• Integrated rotary C-axis with ±2 arc seconds indexing; supports automatic workpiece exchange
