Used Milltronics RH30: Sell or Buy at Auction
Milltronics is an American CNC machine tool builder known for the Centurion conversational CNC control system that makes part programming accessible without G-code expertise. Milltronics vertical machining centers and knee mills are a popular choice in job shops, toolrooms, and educational environments throughout North America. Domestic manufacturing and parts support provide strong serviceability.
The Milltronics RH30 is a heavy-duty 3-axis CNC vertical machining center built by Milltronics USA and run by the company's Centurion conversational control, commonly Centurion 6 or Centurion 7. Despite the "30" in its name, which refers to the 30 inch Y-axis, the RH30 sits toward the larger end of Milltronics' VMC lineup: it pairs roughly 60 inches of X travel and a table in the 73 by 24 inch range with a rigid box-way frame that weighs around 11,000 pounds. A CAT 40 spindle turning up to 8,000 rpm on a 24/15 HP two-speed motor, along with a 24-position automatic tool changer on so-equipped units, gives it the reach and rigidity for long parts, large fixture and tooling plates, mold and die work, and steady production runs rather than only small prototype jobs. The Centurion control also lets a shop program straightforward parts conversationally without deep G-code experience, which is why the RH30 turns up in production shops, tool-and-die shops, and general job shops that want long-part capacity without a steep programming curve. KD Auctions moves RH30 units through active bidding across our network of 500,000+ industry contacts, especially when the machine is verified running with its original Centurion control intact.

Frequently Asked Questions
What is a Milltronics RH30 worth at auction?
Auction value for a Milltronics RH30 depends on its age, spindle hours, overall condition, the health of the Centurion control, and the tooling and tool changer included in the sale. Rather than guess, KD Auctions offers a free AMEA-accredited, USPAP-compliant appraisal that reports both orderly liquidation value (OLV) and forced liquidation value (FLV), so you know where the machine stands before you decide how to sell it.
Who typically buys a Milltronics RH30, and how do I sell mine?
The RH30's most active bidders are production shops, tool-and-die shops, and general machine shops that want its long-part capacity and value the Centurion control's conversational programming along with Milltronics' domestic parts support. To sell yours, call KD Auctions at 480.455.3910. A managed auction typically runs 6 to 10 weeks from engagement to payout, and onsite dispatch is scheduled within 48 to 72 hours, which matters for rigging a machine that weighs in the 11,000 pound range. Commission is tailored to the engagement and quoted upfront, so most sellers pay nothing out of pocket.
