10" x 20" Warner & Swasey #1020 NC Hydraulic Cylindrical Grinder

Serial Number: 30883 | Year of Mfg: 1980 | Design: Angle Head / Micro-Grind

Overview

Available for immediate service is this Warner & Swasey 1020, a heavyweight of the precision grinding world. Engineered for high-volume production and "tenths" accuracy, this machine features the legendary concrete-filled base construction, providing the ultimate in thermal stability and vibration dampening.

Serial #30883 is an Angle Head configuration, allowing for simultaneous grinding of diameters and adjacent shoulders in a single plunge. Equipped with NC Hydraulic automation and in-process gauging, this machine is a "set-and-forget" production workhorse that bridges the gap between manual operation and full CNC.

Key Features & Capability

• Concrete-Composite Base: The massive mass of the 1020 base absorbs harmonic vibrations that plague lighter cast-iron machines. This allows for a "mirror" surface finish and extreme repeatability over long shifts.
• Angle Head Plunge Grinding: The wheel head is set at an angle to the workpiece, making it the ideal solution for grinding shafts with shoulders or flanges where concentricity between the face and the diameter is critical.
• Micro-Grind NC Control: Features an automated cycle for rapid approach, dual-rate grind feed, and a timed spark-out, significantly increasing throughput and reducing operator error.
• Control Gaging #820: Includes a high-precision in-process gauging head. The machine monitors the part diameter in real-time and automatically retracts the wheel head once the target dimension is achieved.
• Precision Spindle: Large-diameter spindle with high-capacity bearings designed for the heavy rotational mass of a 24" grinding wheel.
