Our quality management systems comply with the requirements of various industry quality standards, but more importantly, Bircher Incorporated strives not just to meet but to exceed the requirements and expectations of our customers. Our reputation and success with manufacturing top quality boat shaft systems has steadily increased the demand for our services. Our business experience meeting the demands of professional engineering departments has raised the bar and enhanced our already keen quality control standards. Plus, we have a real world approach to manufacturing shaft systems which provides reliable and superior quality products that perform correctly the first time. Bircher Inc. uses CNC capabilities as well as conventional machinery to their best advantages. Bircher Inc. can also offer consulting, manufacturing engineering, and allowances for special considerations.

We work closely with our customers to achieve solutions and to meet contract requirements. We have the knowledge and background to make suggestions for product upgrades. We have the experience to assist with research and development projects. Our employees and machinists are talented, experienced and seasoned; our team of experts is our greatest asset. We encourage a creative processing method with an open exchange of ideas and information. We communicate this process with our customers. This "team approach" to quality control ensures highest quality as well as superior manufacturing and service results.

Boat shafts are custom manufactured to each individual vessel#8217;s specifications and requirements. All finished shaft systems are carefully inspected and triple checked for quality control, including a dye test, to meet exact tolerances before being allowed to be picked up or shipped.

The degree of quality determines the useful life of boat shaft systems. Proper engine/shaft alignment of drive systems is critical to top performance especially with larger vessels and the shaft straightness becomes more crucial with the longer and larger shafts. A few degrees off at one end of a long shaft could translate into inches off at the other end.

Our Straightening Presses

We have small, medium and large straightening presses providing 4 ton, 50 ton, and 100 ton capacities. We can straighten shafts up to 30 feet in length. Shaft straightness is a serious priority; we spend as much time monitoring shaft straightness as in the machining of the shafts. Shafts are straightened by cold bending to factory specifications.
