Fairoaks - High Speed Precision Press Machine (Crank Type)
A crank type press converts continuous rotational motion from an electric motor into a fixed, repeating up-and-down stroke of the slide through a crankshaft-driven mechanism. The design's mechanical simplicity, repeatable stroke geometry, and high strokes-per-minute (SPM) capability have made it a standard production method for manufacturers producing large quantities of metal components to tight tolerances.
According to the technical resource, key factors that determine a crank type press's suitability for high-speed motor lamination work include frame rigidity, bearing design, and dynamic balance, all of which affect long-term dimensional accuracy under sustained high-SPM operation.
"Crank type presses remain the standard for high-speed, high-precision stamping, but frame rigidity, bearing design, and dynamic balance are what actually separate reliable long-term performance from costly downtime," said a Fair Oaks spokesperson. "That distinction becomes more important as EV and hybrid motor production scales up and lamination tolerances get tighter."
Fair Oaks manufactures its own line of crank type presses under the GH Series, ranging from 45 to 330 tons. The press frames are built from stress-relieved, high-tensile cast iron and optimized through finite element analysis (FEM), then assembled under hydraulic tie-rod preload for added rigidity. Clearance-free axial bearings on the plunger and slide guides, combined with a forced lubrication and cooling system, are designed to maintain JIS Special accuracy over sustained production runs.
The published technical resource covers the full stamping cycle of a crank type press -- from flywheel energy storage and clutch engagement, through the slide's descent to bottom dead center, to material ejection and feed advance -- along with the industries that depend on the technology, including EV motor lamination, 3C electronics, automotive parts, home appliances, and industrial motors.
