USED 1987 LANDIS 2RU

1987 Landis 2RU Universal Hydraulic Cylindrical GrinderModel: 2RU | S/N 877-53 | 14" x 36" CapacityOverviewThe Landis 2RU is an industrial benchmark for precision cylindrical grinding. Manufactured in 1987, this unit represents the final, most refined era of Landis’s manual hydraulic machines. The "U" designation stands for Universal, signifying a machine capable of both external (OD) and internal (ID) grinding thanks to its integrated swing-down internal attachment.Built on a massive, hand-scraped cast iron frame, this 7,200 lb machine is engineered to dampen vibration and maintain thermal stability, ensuring sub-micron finishes and tight tolerances even during high-production shifts.Technical SpecificationsYear of Manufacture: 1987Swing Over Table: 14" (Max capacity 14-31/32")Distance Between Centers: 36"Workhead Speeds: Infinitely Variable (Low: 30–150 RPM | High: 120–600 RPM)Spindle Taper: #10 Jarno (Workhead) / #6 Jarno (Tailstock)Table Traverse Speed: 2 to 240 IPM (Hydraulic)Grinding Wheel Size: 14" x 1.5" x 5" (Standard OD)Internal Spindle Speed: Approx. 18,000 RPM (Swing-down attachment)Motors: 3 HP Wheel Drive | 1 HP Internal Fixture | 1/3 HP Work DriveDimensions: Approx. 129" L x 64" W x 50" HWeight: Approx. 7,200 lbsKey Features & Dealer BenefitsSwing-Down ID Attachment: Switch from OD to ID grinding in seconds without disturbing the workpiece setup. This feature is essential for grinding bores perfectly concentric to the outer diameter.Hydraulic Precision: Features fully automatic table traverse with "Pick Feed" at reversals, allowing for consistent, automated material removal.Universal Swiveling Workhead: The workhead swivels 120 degrees, allowing for the grinding of steep tapers, faces, and complex angles.1980s Electronics & Hydraulics: Being an '87 model, this machine uses modern industrial electrical components and refined hydraulic valve blocks, making it far more reliable and easier to service than 1950s/60s "Legacy" units.Rigidity & Finish: The heavy-duty base provides the mass required for mirror-like finishes, making it the preferred choice for aerospace, automotive, and high-precision tool and die work.
