Shaft Straightening Machines

Kokusai offers an impressive variety of shaft straightening machines designed to correct the distortions common to manufacturing. Applications vary from precision office equipment, such as surgical drill bits, to large construction equipment shafts. Our machines are successfully used to straighten camshafts, oval rings, armatures, and crank shafts. Straightening is an important resource for manufacturing, as a bent part can cause material fatigue, as well as machine vibration and unbalance due to bearing wear. Developing precision straightening equipment is both a science and an art, and Kokusai is proud to be effective at the more difficult applications for straightening, for example the complex geometry of rack and pinion systems. Our engineers have reached exceptional proficiency in this area, meeting the most demanding customer requirements.

Our machinery is available to be tailored to customers’ exact needs. We are able to work with your company to find the best solution to consolidate our machinery into your existing production methods.
