What AccuRounds does
AccuRounds, Inc. is a precision CNC contract manufacturer founded in 1976 by Len Tamasi (originally as B&F Swiss in Canton, MA) and now led by second-generation owner Michael Tamasi as President and CEO. The company operates from a single 45,000 sq ft state-of-the-art facility in Avon, Massachusetts, and is privately held by the Tamasi family with no disclosed institutional capital or public listing. Its core manufacturing capabilities span 12-axis CNC Swiss screw machining, multi-axis CNC turning and milling, centerless/cylindrical/CNC precision grinding, robotic automation (Universal Robots UR10e/UR5e, Robo2Go), and in-house 3D printing (Ultimaker S5 Pro, Artillery Sidewinder X2). The company holds tolerances to .000020 inches for medical micro-machining and .000050 inches for grinding, with diameters from .005" to 6.0" and lengths to 12'. Certifications include ISO 9001:2015, AS9100 (expires August 2028), and ITAR registration, enabling work in aerospace and defense supply chains.
The company serves five primary verticals — Aerospace, Defense, Medical, Semiconductor, and Emerging Technology (alternative energy, robotics, biotechnology, display) — with component applications including firing pins, orthopedic implants, bone screws, semiconductor valves, and precision rollers. Service revenue is generated through a quote-based, custom-component model with engineering collaboration on design for manufacturability, prototype validation, and production runs. Customer relationships are supported by lean programs (Kanban, JIT, dock-to-stock, pull systems) and a Supplier Certification Program that manages heat treat, plating, and testing. Go-to-market is direct enterprise sales led by a dedicated sales organization (VP Sales, Sales Coordinators, Account Representatives), with lead generation through industry associations (NTMA, PMPA, GBMP, MassEcon), trade publications (Modern Machine Shop), and a website-driven RFQ workflow.
Strategic positioning rests on three differentiated elements: (1) early-mover status as one of the first U.S. contract manufacturers to adopt CNC Swiss technology (1979), with multi-decade Swiss expertise; (2) a Shingo Prize-recognized lean manufacturing culture (2006, first metalworking contract manufacturer in North America) that supports smaller lot sizes and shorter lead times; and (3) full vertical integration of precision processes in-house — eliminating the need for outside grinding, engineering, or (as of 2026) parts cleaning — which simplifies customer supply chains in regulated industries. Customer concentration and revenue figures are not disclosed.
