The five-axis Nozzle Master from Micro EDM Machine & Tool is designed for high-precision small-hole production EDM. The machine produces holes ranging in size from 0.003" to 0.015". A solid welded and normalized base with granite table top and vertical uprights provides rigidity. The XYZ slides are constructed of stainless steel and oversized for additional rigidity and accuracy.
The 1"-stroke, DC-powered EDM head slide with automatic electrode handling replenishes used electrodes via hitch-feed motion. Wire guides provide repeatable electrode location, and electronic feedback enables programmable depth control. The machine features upper and lower over-travel limits and an adjustable up-stop limit.
The M-1 1-amp EDM power supply is rear-panel-mounted, and all EDM and motion settings are controlled via a touch-screen panel. A pendant arm control box is provided, along with a handheld pendant for manual jogging of the machine. Power level by depth, range, capacitance level, polarity reversing, hitch feed, hitch feed reverse, depth setting, and all CNC motion and machine functions are controlled through the touchscreen or G/M codes in the program.
Editor PickEDM Enables DIY Form Tools
This manufacturer uses its EDM unit to make and sharpen form tools for its production equipment. Strategically, learning new skills in-house may lead to future commercialization of a value-added process not previously available. It could be a model for other shops.
