3M 7000044834 Diamond Lapping Film 30.0 Micron Roll

Product Description

The 3M 7000044834 is a diamond lapping film supplied in roll form, designed for precision material removal and surface finishing in trade and industrial applications. Built on a reinforced resin system for added toughness and extended service life, this film delivers consistent cut and finish across demanding cycles. The roll measures 4 inches wide by 50 feet long and is wound on a 3-inch core, making it compatible with standard roll-polishing equipment. At a 30.0 micron grade, it is suited for intermediate lapping and superfinishing stages where controlled stock removal and repeatable surface finish are required.

This diamond lapping film is used primarily in superfinishing, roll polishing, and flat lapping applications. Typical end users include precision grinding shops, tool and die operations, optical fabricators, and industrial maintenance technicians working with hard or difficult-to-finish materials such as ceramics, carbide, and hardened steel. The 30.0 micron grade fits between coarser stock-removal stages and finer polishing steps in a multi-stage finishing sequence.

Key Features

• Reinforced resin bond system provides added toughness and longer film life compared to standard lapping films
• 30.0 micron diamond grade delivers controlled intermediate cut for superfinishing and flat lapping
• Roll format (4 inches x 50 feet) minimizes changeover frequency on continuous or semi-continuous polishing equipment
• 3-inch core fits standard roll-polishing machine mandrels
• Consistent abrasive distribution across the full roll length supports repeatable surface finish results

Compatibility

Designed as an OEM-style replacement or direct-use consumable for roll polishing machines, flat lapping fixtures, and superfinishing equipment that accept 4-inch wide abrasive film rolls on a 3-inch core.

Installation Notes

Loading and threading lapping film rolls should be performed by a qualified machine operator following the equipment manufacturer's guidelines. Power down and de-energize the polishing machine before loading a new roll. Ensure the film path is free of debris and that tension settings are appropriate for the film thickness to avoid tearing or uneven wear. Consult the equipment manufacturer's documentation for feed rate and pressure recommendations specific to diamond lapping films.
