What Centroid CNC does

Centroid CNC is a Pennsylvania-based, privately held designer and manufacturer of CNC machine tool control systems, founded in 1979 and operating from Howard, PA with a small staff (11-50 employees). The company sells a portfolio of five controller boards — Acorn (4-axis step/direction, $369 entry kit), AcornSix (6-axis), Allin1DC (6-axis DC servo closed loop), Oak (8-axis AC/DC servo), and Hickory (8-axis EtherCAT) — paired with its proprietary CNC12 software platform (Free, Pro, and Ultimate tiers for Mill, Lathe, Router, and Plasma). The technology architecture is a hybrid model that pairs a Windows PC (for UI and G-code/INTERCON conversational programming) with a dedicated Centroid Motion Processing Unit and on-board PLC for real-time motion control, with the Hickory controller adding EtherCAT servo communication supporting Yaskawa, Leadshine, Glentek, Estun, and Inovance drives. The company monetizes through hardware sales (controllers, servo motors/drives, touch probes, rotary tables, consoles), one-time CNC12 software license upgrades, and professional services (on-site training at $1,000/day, factory tech support at $120/hr, retrofit installations, replacement parts for legacy systems). Touch probe IP (patented KP-3 kinematic and DP-4/DP-7 digital probes claiming 1-micron repeatability) is positioned against Renishaw and Marposs at lower cost and with broad third-party CNC compatibility. Centroid serves a heterogeneous base spanning DIY hobbyists, small-to-medium machine shops performing retrofits of older Haas/Fadal/Bridgeport/Fanuc controls, OEM machine builders (Atrump, Wells Index, Icarteam), performance engine builders via the Centroid Performance Racing sub-brand, and educational/training buyers, distributed through direct e-commerce, authorized global resellers, and field sales for turn-key systems. All products are designed and manufactured in the USA.

• Fanuc: Global leader in CNC controls, servo motors, and robots with dominant industrial installed base. Comparable as the high-end incumbent whose legacy controls Centroid retrofits, and whose DP-4-compatible controllers represent both Centroid's probe expansion opportunity and CNC system competition.
• Siemens (Sinumerik): Industrial automation conglomerate with Sinumerik CNC control line serving high-end machine tools globally. Comparable as a competing retrofit target for legacy Siemens-controlled machines and a high-end alternative to Centroid's EtherCAT Hickory platform.
• Fagor Automation: Spanish CNC control and automation specialist with broad installed base in North American machine shops. Comparable as both a retrofit source (legacy Fagor controls Centroid replaces) and a competitor in the mid-range CNC controller market.
• Haas Automation: Largest US-based CNC machine tool builder with proprietary control systems. Comparable as the dominant US competitor Centroid explicitly targets in retrofits (4-axis Centroid mill for less than half the cost of a 3-axis Haas, per customer testimonial).

Emerging players

• LinuxCNC: Open-source CNC control software supporting a wide range of machine controllers. Comparable as a free alternative to Centroid's CNC12 platform, particularly in the hobbyist and educational segments where Centroid's KP-3 and DP-4 probes maintain compatibility.
