14 in Diamond Flat Lap Disc with Magnetic Backing for Precision Grinding & Polishing

Overview

The 14 in Diamond Flat Lap Disc with Magnetic Backing is a commercial-grade, heavy-duty electroplated diamond grinding disc engineered for 14-inch lapidary flat laps, cold glass grinding units, and precision stone faceting equipment. Featuring a high-density, full-face electroplated diamond matrix bonded to a rigid disc plate with a magnetic or PSA backing system, this flat lap ensures instantaneous disc changes, rock-solid stability, and dependable surface flatness across glass, ceramics, gemstones, and hard minerals.

Key Features

• Full-Face Diamond Plating: Uniformly electroplated diamond abrasive delivers consistent, high-efficiency stock removal across the full 14-inch surface without bald spots or uneven wear.
• Magnetic & PSA Backing Options: Designed for rapid magnetic mounting onto steel master laps or adhesive mounting on acrylic plates, streamlining multi-step grinding and smoothing workflows.
• Rigid Ground Plate: Precision-engineered flat backing eliminates flex under grinding pressure, guaranteeing flat facets, crisp miters, and accurate bevels.
• Wide Grit Range (45 to 600 Grit): Supports every production phase, from aggressive rough grinding and edge hogging to fine smoothing and pre-polishing.
• Wet Grinding Durability: Optimized for continuous water coolant operation to dissipate frictional heat, flush grinding debris, and maximize diamond lifespan.

Applications

• Large gemstone rough shaping, cabochon flattening, and facet pre-polishing
• Architectural art glass beveling, cold glass edge smoothing, and sculptural flattening
• Grinding and leveling ceramic, porcelain, and pottery vessels
• Flattening large mineral specimens, agate slabs, quartz, and petrified wood

Technical Specifications

• Disc Diameter: 14 inches (350 mm)
• Abrasive Type: Precision Electroplated Diamond
• Backing System: Magnetic Backing / Pressure Sensitive Adhesive (PSA)
• Available Grits: 45, 60, 80, 100, 140, 200, 270, 325, 600 Grit
• Machine Compatibility: 14-inch flat lap machines (Hi-Tech Diamond, Covington Engineering, Inland, Lortone, and Hans flat laps)

Operating Guidelines

• Always use continuous water lubrication to cool the workpiece and disc while flushing away swarf.
• Maintain light to moderate, even downward pressure across the disc face; allow the diamonds to cut naturally.
• Clean both the disc surface and the master lap thoroughly between grit steps to prevent contamination.
• Dry and store flat after use to preserve magnetic adhesion and maintain optimal disc performance.
