High-Precision Spindle Finishing

A compact, high production spindle-finishing machine engineered for highest precision and performance in deburring small gears and machined parts is now available from Almco, Inc. Requiring almost 15 square feet of floor space, the Model S2-30 finishes as many as 480 pieces per hour with extreme uniformity and consistency and exact process repeatability. Parts measuring up to 2 1/2" × 3" are loaded on one or both of the machine's spindles, either manually or with robotics if desired, and unloaded after a typical 15-second deburring cycle.

Parts measuring up to 2 1/2" × 3" are loaded on one or both of the machine's spindles, either manually or with robotics if desired, and unloaded after a typical 15-second deburring cycle.

Spindle finishing offers numerous benefits not possible with conventional finishing equipment, the company says. Highest precision of parts is attained, and many can be deburred in no other way because of requirements for extreme accuracy. Process repeatability is ensured through elementary adjustments of the equipment and simple procedures performed without special operator skills.

Complex parts are mounted on the S2-30's air-actuated collets or ID expanding collets at the ends of the rotating spindles. The spindles then pivot into the rotating tub, placing the workpieces in a stream of abrasive slurry moving at speeds of as high as 2,000 ft. per minute.

Centrifugal force spins the slurry into a form-fitting "grinding wheel" while slow rotation of the part in the mass ensures uniform deburring and finishing of all surfaces. The spindle heads automatically return to the up position at the end of the preset time cycle.
