What We Do
Full-service precision machining under one roof
From first-article prototypes to repeatable production runs, our shop floor is built to hold tolerance on the materials that matter most.
CNC Turning
Multi-axis turning with live tooling and bar feed for high-throughput round and prismatic parts.
Swiss-Type Machining
High-volume small precision components held to ±0.0002", ideal for medical and connector work.
Wire & Sinker EDM
Intricate profiles, sharp internal corners, and hardened-material detail no cutter can reach.
Precision Grinding
Surface and cylindrical grinding for mirror finishes and tolerances down to a tenth.
Inspection & Metrology
CMM and in-process inspection with full material traceability and first-article reporting.
Also available: engineering & DFM support, light assembly, kitting, deburring, passivation, anodizing, and plating through our qualified finishing partners.

Our Story
Three generations of machinists. One standard.
Precision Machine Co. opened in 1987 as a two-man job shop with a single manual lathe and a promise: hold the tolerance, hit the date, no surprises. Nearly four decades later that promise still runs the floor.
Today we're a 35-person operation in a 28,000-square-foot facility in Cincinnati, Ohio — still family-owned, now led by second-generation owner Mike Bennett. Our machinists, programmers, and quality engineers treat every part like our reputation depends on it, because for the OEMs and engineers who count on us, it does.
