We are the “Flatwork Specialists”. We have one of the Midwest’s most complete machine shops dedicated to making parts flat. We have Double disc, Blanchard, Surface grinding with both single and double-sided lapping machines. Our state of the art “Flat Honing / Fine Grinding” machines can hold a thickness tolerance of +/- 1 micron on a given load of parts and hold flatness across a part of 1 light band (one eleven millionth of an inch). We are a job shop in nature, so we carry a very extensive inventory of abrasives; this combines with our many years of grinding experience giving us the ability to accomplish most any job. We cover the complete spectrum from simple one-piece orders to large production runs of over 1,000,000 pieces with 95% of our sales being performed on customer supplied parts. Our value added services such as vibratory deburring, parts washing and packaging allow us to complete your order from start to finish. We are ISO 9001:2008 certified.
