Used WILSON / ROCKWELL 4JR PL #9300750 for sale

WILSON / ROCKWELL 4JR PL is a high-precision wafer grinding, lapping and polishing equipment that produces superior surface quality on bare as well as coated or fused wafers. Designed for extremely fast throughput, WILSON 4JR PL features a automated wafer handling system that offers user-configurable operation and up to six inches wafer diameter capacity. The machine offers separate modules for grinding, lapping, and polishing, which deliver a complete end-product in one pass. The unit is powered by a high voltage DC motor drive that provides both rapid and repeatable acceleration/deceleration profiles. It produces centerless and random uniform grinding, lapping, and polishing via an integrated carousel mechanism which at speeds up to 2800 RPM. A 3-axis CNC controller with absolute servo motors allows precise relative positioning for optimized quality control and simplified machine setup and alignment. ROCKWELL 4JR PL features a two-stage filtration machine which improves the working environment. Each station includes coolant spray for efficient heat removal and improved structural rigidity of the workpiece, while a recirculation tool offers precision coolant control. Further, its dust handling asset uses a cyclone and centrifugal separator to maintain the cleanliness of the working environment. Overall, 4JR PL offers superior precision grinding, lapping, and polishing of hard materials with minimally maintained hand finishing. It excels in surface preparation for IC, silicon, gallium arsenide, and other substrates. This durable and easy to use model finishes wafers quickly while providing impressive surface finishes that requires minimal post process labor.
