Used Mazak Integrex i-300: Sell or Buy at Auction
Mazak is one of the world's largest and most respected machine tool manufacturers: known for advanced multi-tasking machines, high-speed machining centers, and the Mazatrol conversational control system. Mazak machines are a mainstay of aerospace, automotive, and precision manufacturing environments globally.
The Mazak Integrex i-300 is a CNC multitasking machine that combines a full turning lathe and a 5-axis machining center in one platform, completing turning and milling in a single setup. It pairs a high-torque main turning spindle that swings work up to about 658 mm (roughly 26 inches) in diameter, with bar capacity in the 3-inch class (around 80 mm), and an integrated milling spindle that runs to 12,000 rpm on a B-axis head swiveling through about 240 degrees for full 5-axis simultaneous machining. Offered in several distance-between-centers configurations and running Mazak's Mazatrol SmoothX control, it is built for shops that turn complex shafts, housings, and round parts complete, removing the second setup a separate lathe and machining center would otherwise require. Aerospace suppliers, energy and defense contractors, and precision job shops choose this size of Integrex for real multitasking capacity without the footprint or cost of Mazak's largest platforms. Multitasking machines like the Integrex hold their value and draw active bidding at auction, and KD Auctions markets each one to its network of 500,000+ industry contacts to reach serious bidders across North America, Asia, and Europe.

Frequently Asked Questions
What is a used Mazak Integrex i-300 worth at auction?
Auction value depends on the machine's age and spindle hours, the Mazatrol control generation (an older Matrix versus the newer SmoothX), the turning and milling configuration, the tooling package, and overall condition. Options that move the number include a sub-spindle or lower turret (the i-300S and i-300ST builds), a bar feeder, a Y-axis, and extra tool magazine capacity. KD Auctions provides a free AMEA-accredited, USPAP-compliant appraisal that establishes both orderly liquidation value (OLV) and forced liquidation value (FLV), so you know exactly where the machine stands before it goes to sale.
How does the Integrex i-300 compare to the other Integrex models?
The i-300 sits in the mid-size range of Mazak's horizontal Integrex line. Compared with the compact i-100 and i-200, it brings a larger, higher-torque turning spindle, bigger bar capacity, and longer distance-between-centers options, so it can turn and mill mid-to-large shafts and housings complete in one setup. Step up to the i-400 and i-500 for greater turning capacity and heavier stock, or to the vertical i-630V for large, heavy parts. Mazak has since moved to its i NEO generation, so most i-300s on the market are proven, in-service machines, which is part of why they draw steady interest at auction.
