Wear pad B4

Description
Style "B" master feed finger pads are uniquely designed and proven by over fifty years of use in the machine tool industry. The straightforward design allows for full bearing of the pad ID on the workpiece. There are no screws or tabs to wear or to remove bearing area from the pad ID. The master feed fingers are spring tempered to the proper gripping tension for long service life. Custom master feed fingers can be manufactured quickly at Hardinge to provide very light or heavier grip for nonstandard applications. Using Style "B" master feed fingers reduces downtime on the production floor.

Advantages

• Dependable. There are no screws or pins to hold pads in place; pads cannot come loose and they provide full bearing on the bar stock.
• Versatile. Pads are stocked in round, hexagon and square shapes, in a variety of materials and sizes.
• Cost-effective. The versatility of a master feed finger is increased by purchasing inexpensive pads in different sizes and shapes.

Pad Material

• Hardened steel pads are for hot-rolled and cold-drawn stock. This pad type offers long wear and minimizes scoring due to its greater hardness. With our Style "B" master feed finger acting as a durable holder, you can select pads to meet precise requirements.
• Nickel cast iron pads are for brass, aluminum, polished or plated bars and special-finish drawn bars to eliminate scoring. This material was selected after extensive testing to reduce scoring and ensure long wear.
• Bronze pads are for ground drill rod, ground bars, and for the same materials listed for nickel cast iron pads (except brass) to eliminate scoring.
