Capabilities
Where They Excel
Precision Medical Manufacturing
Accu-Tool manufactures precision components and tooling for medical and life sciences applications where dimensional accuracy, consistency, and documented quality are essential. Decades of experience machining complex parts support demanding prototype and low- to mid-volume programs from development through production.
Core Capabilities
Shared Platform Capabilities
CNC Milling and Turning
Multi-axis CNC milling and turning covers prototype through low-to-mid volume OEM production.
Wire EDM
In-house Wire EDM supports intricate, difficult-to-machine geometries.
Horizontal Milling
Horizontal machining centers reach multiple faces of a part in one setup, holding position across features on prototype and production runs alike.
Mill-Turn
Turning and milling finish in a single sequence instead of moving between machines, so a part comes off the spindle one and done.
CMM Inspection
Part inspection and documentation support full dimensional verification.
Material Experience
Engineered plastics, traditional metals and alloys, and the high-temperature refractory metals most shops avoid. Molybdenum and tungsten are a regular material at Accu-Tool, not a special case.
