Warpage including bow, waviness, and twisting can easily be identified and measured by O’Hare Precision Metals manufacturing experts. Our professionals correct these conditions, ensuring that stringent straightness and tolerances are adhered to. Our precision bar production and conversion grinding support the straightness you specify and require in making highly accurate component parts.
Despite using bars with strict straightness tolerances before machining, some components fail to maintain this tolerance after machining. O’Hare Precision Metals, however is capable of bar re-straightening for most material types.
Operators of Swiss type turning lathes know that at the very high RPM’s at which these machines typically run (6-8,000 RPM), just a little vibration can wreak havoc on your ability to consistently produce high precision parts with the right surface finish. That is why Ohare Precision Metals goes to extraordinary measures to ensure that our precision bars and conversion grinding utilize a variety of straightening techniques developed over the years which results in the most consistently straight precision bars in the industry.
We have also developed proprietary methods for measuring the straightness of bars. These methods ensure you are getting the straightness you specified and need to make the most accurate component parts.
Because we have many years of experience working with straightening issues, we can quickly identify and measure the various types of bent conditions, such as bow, waviness, twisting, etc. and use our expertise to rectify these conditions over the length of the bar.
Even when utilizing the straightest bars prior to machining, certain components do not lend themselves to tight straightness tolerances once the machining is complete. If there is a large length to diameter ratio for instance, maintaining very accurate part straightness can be difficult. Or if a part needs heat treatment after machining, parts can bend and warp.
With three Medart strengtheners for small diameters and one 150 ton hydraulic press for large diameters, we have the capability to straighten all the material that we can grind to industry standards.
