Harig 618W 6" x 18" Automatic Hydraulic Surface GrinderPrecision Toolroom Standard | Automatic Table Feed | Flo-Clean System"World-Class Precision for the Modern Toolroom"Available for acquisition is the Harig 618W, the industry benchmark for precision surface grinding. Unlike manual models, the 618W features a hydraulically powered longitudinal feed, providing the ultra-smooth, consistent table travel necessary for achieving mirror-like surface finishes and extreme flatness.Built on a heavy-duty Meehanite casting, this machine is engineered for shops that require both high-accuracy prototyping and light production capability. This unit features Harig’s proprietary Flo-Clean automatic recirculating oil system, which continuously flushes the ways with filtered oil to prevent grinding grit from compromising the machine's precision.Technical SpecificationsTable Working Capacity: 6" x 18"Longitudinal Travel (X): 20"Cross Travel (Y): 6-3/4"Vertical Travel (Z): 11-3/4" (Under 7" wheel)Standard Wheel Size: 7" x 1/2" x 1-1/4"Table Speed (Hydraulic): 3 – 70 FPM (Infinitely Variable)Spindle Speed: 3,450 RPMMotor: 1.5 HP Direct DriveApprox. Machine Weight: 1,500 lbsKey Features & Dealer AdvantagesHydraulic Longitudinal Feed: The front-mounted manifold provides a "cushioned" table reversal, eliminating the jarring vibration found in lesser grinders and ensuring a superior finish.Flo-Clean Oiling System: A self-contained, filtered lubrication system that bathes the spindle housing and ways in clean oil. This system is the primary reason Harig grinders maintain their value and accuracy for decades.Direct Drive Spindle: The spindle motor is coupled directly to the grinding head, eliminating belts that can flap or slip, resulting in a quieter, vibration-free operation.Hardened & Ground Ways: Hard-chromed longitudinal ways provide maximum wear resistance and long-term geometric alignment.Manual Override: Can be quickly converted back to hand-feed operation for delicate one-off tasks where the operator requires "tactile" feedback.
