About Us

An Experienced Machining Company in
Spring Grove, Illinois

Olson Machining, Inc. is a make-to-order CNC precision machining specialist with expertise in multitasking, turning, and milling. Our long-standing customer relationships are a result of the exceptional service, quality, and productivity improvements necessary for today’s demanding manufacturing environment.

Our core operating philosophy is to have no one customer representing more than 20% of our total business, and we seek out new business partners that are looking for reliable, cost-effective suppliers and long-term relationships. To serve the demands of different industries, we have structured our operations into two centers of excellence: 'JOB SHOP' and 'PRODUCTION'.

The 'JOB SHOP' center is configured for small quantity runs and parts that will repeat over time. This team excels in delivering complex, intricate parts while offering great value through focused expertise and efficiencies. This center was established to serve the low volume production and spare parts industries.

In order to serve the special needs of your business, our customer service has procedures for tracking 'HOT ORDERS'. Quotes are typically turned around in 48 hours with immediate, over the phone pricing for repeat orders to eliminate delays.

Investments in state-of-the-art robotic equipment, trained staff, and quality processes enable Olson Machining to deliver maximum throughput with, in many cases, single operations. Work teams dedicated to employing lean principles, with systems and processes focused to deliver maximum productivity and competitive pricing to our customers.

Whether job shop or production parts, all parts pass our quality systems and are shipped deburred, preserved, and packaged to prevent shipping and handling damage. We take great pride in our workmanship and employ procedures to exceed our customer expectations.
