The soft, pliable rubber expands during rotation to grip the sanding or polishing belts.Belts can be quickly changed by stopping the machine, slipping of the old one and sliding on the new. In use, the resilient drum surface flexes to the gemstones contour to quickly remove grinding flats. The convex shaped drum provides the cutting action necessary to remove scratches.Expandable Drum Sander wheel will expands when the machine is turned on which holds the sanding  belts in place when the machine is running.Sold without belt. Maximum recommended speed is 1800 RPM. CAUTION: Do not run the drum without belts in place as damage to the rubber rim may result.

Features:

  1. Angled Expansion Slots: The Expandable Rubber Drum Sander wheel features strategically placed expansion slots within its heavy rubber rim. These slots are designed to allow the drum to expand when rotated, effectively locking the sanding or polishing belt in place during operation.

  2. Secure Belt Grip: When the wheel is in use, the soft and pliable rubber surface expands during rotation, securely gripping the sanding or polishing belts. This design ensures that belts remain firmly in place, preventing slippage and ensuring consistent results.

  3. Quick Belt Changes: Changing sanding or polishing belts is a hassle-free process. It involves stopping the machine, sliding off the old belt, and sliding on the new one. This quick and straightforward belt replacement mechanism enhances productivity.

  4. Contour-Friendly: The resilient drum surface flexes to match the contour of the gemstone or workpiece being polished. This feature allows for the rapid removal of grinding flats and ensures that the drum adapts to the shape of the material, delivering even and precise results.

  5. Effective Cutting Action: The convex-shaped drum provides the cutting action required to remove scratches and imperfections from the material. It ensures that the abrasive process is efficient and produces a smooth, polished finish.

  6. Secure Belt Hold: The Expandable Drum Sander wheel expands when the machine is turned on, effectively holding the sanding or polishing belts in place throughout the operation. This secure hold ensures operator safety and consistent performance.

  7. Sold Without Belt: The product is sold without a sanding or polishing belt, allowing users to select belts of their choice based on their specific needs and preferences.

Frequenstly Answer Qeustion

Q: What are the situations where diamonds are used as cutting tool?

Diamond excels in "hardness" and "heat diffusibility" as a cutting tool material. CBN, with hardness akin to that of diamond diamond is mainly used for cutting ferrous metal thanks to its lower reactivity than diamond with ferrous metal. Both materials can be polished to form "sharp cutting edge."

Q: What are the benefits of diamond tools?

Advantages. Diamond is one of the hardest natural materials on earth; much harder than corundum and silicon carbide. Diamond also has high strength, good wear resistance, and a low friction coefficient. So when used as an abrasive, it has many obvious advantages over many other common abrasives.

Q: How are diamond tools made?

High-quality Diamond cutting tools are manufactured with electrolytic iron powder where it acts as a part of the binder alloy and offers the specific arrangement of the diamond composites on to the surface of the tools.

Q: How do diamond tools work?

The actual grinding work is done by exposed diamond crystals that are held in place by the metal matrix or bond. Each diamond is supported by a bond tail which trails behind the diamond. While the blade rotates through the material, the exposed diamonds on the surface grind the material.
