# Kitamura Mycenter-3020G Sparkchanger

Hardware · `Mycenter-3020G` · verification: source checked

The Mycenter-3020G Sparkchanger is a vertical 3-axis machining center with a 180-degree rotating two-station automatic pallet changer, so pallets can be loaded and unloaded while the other station is cutting. It uses a 20,000 rpm, 4-step gear-driven dual-contact spindle in an NST No. 40 taper and holds 30 tools. Solid box ways on X and Y, ballscrew cooling and an IAC system support work on small to medium-size parts and molds.
