Used CINCINNATI / HEALD 271 #9115818 for sale

CINCINNATI / HEALD 271 is an electro-hydraulic, digitally controlled, NC programmable cylindrical-type grinding machine used for heavy-duty production grinding of external and internal surfaces. This machine has a grinding wheel diameter of up to 12" and can hold work pieces up to 65 inches long. It is powered by a 20 horsepower AC grinding spindle motor and a 15 Hp shaper servo motor. HEALD 271 provides a one-pass grinding process that quickly produces smoothly finished surfaces. It is capable of grinding to extremely tight surface finish tolerances, with profiled and stepped grinds, and a multitude of other tool forms. The rigidity of the machine and its high-precision spindle speed control equipment ensures optimal grinding performance. Software controls on CINCINNATI 271 allow for tight programming tolerances, with the ability to rotate the grinding wheel head at 0.0001 degree increments, with a programmable plunge feed rate of up to 100 inches per minute. Additionally, the machine features a four-way cross-slide set-up system that allows for improved accuracy and faster set-up times between tools. Unique to 271 is its Adaptive Control Unit, which continuously monitors the grinding wheel during the grinding cycle and adjusts the feed rate according to the condition of the wheel. This machine further reduces cycle times and enhances the machine's accuracy. The machine also features a 40 tool Automatic Tool Changer and an Automatic Index Plate that allows for repeatable accuracy in the production of parts with an automatic cycle time setting that eliminates tool changes. The Automatic Wheel Balancing Tool ensures that the grinding wheel is perfectly balanced on a rotating surface at all times for reduced vibration and improved accuracy. To ensure optimal performance of CINCINNATI / HEALD 271, regular maintenance and lubrication of moving parts is recommended. Proper lubrication and upkeep are critical for the longevity and reliable operation of the spindle asset, which allows the machine to accurately produce parts with precision and consistency.
