Frequently Asked Questions

The SMART CUT™ Electroplated Diamond Grinding Wheels are designed for grinding, shaping, and cutting various materials. They are suitable for use on most conventional grinders available today.

Electroplating refers to the process of using an electric current to bond the diamonds to the grinding wheel’s surface. The nickel acts as the bonding medium, ensuring a high-quality and durable attachment of the diamonds to the wheel.

They can be used for grinding various materials, including stones, ceramics, metals, and other hard materials.

Yes, these wheels can be used on most conventional grinders, including brands like Diamond Pacific, Barranca, Maxant, Graves, and other cabbing machines.

The mesh or grit size refers to the granularity of the diamonds on the wheel. The lower the number, the coarser the grit, and the faster the material removal. Conversely, a higher number indicates a finer grit for more detailed or polished work.

The plastic hub makes the grinding wheel lighter, allowing it to be used on less powerful grinding machines. Additionally, it provides flexibility in terms of accommodating different arbor sizes with the included bushings.

The arbor size refers to the hole’s diameter in the center of the grinding wheel where it attaches to the grinder. Our wheels come with a 1-inch diameter and include bushings to accommodate 3/4in., 5/8in., and 1/2in. arbors, ensuring compatibility with various grinder models.

We do not offer re-plating services. Given the costs involved, it is more economical to recycle and replace the wheels once they’ve reached the end of their usable life.

Your choice of grit size depends on the type of work you’re undertaking. Coarser grits (like 60 mesh) are ideal for rapid material removal, while finer grits (like 600 mesh) are suited for polishing or detailed work.

Yes, each grinding wheel is individually boxed for safe and secure transportation.

SMART CUT™ grinding wheels are made with the highest quality diamonds to ensure longer grinding life, cleaner, and faster cutting, setting them apart from many competitor

It’s essential to keep the grinding wheel clean and free from debris. Regularly inspect for any wear or damage, and always use the wheel at the manufacturer’s recommended speed.

Always wear appropriate safety gear, like goggles and gloves, when operating any grinding machinery. Ensure the wheel is correctly attached to the grinder and free from damage before use. Keep the working area well-lit and free from distractions.

While the SMART CUT™ Electroplated Diamond Grinding Wheels can handle both wet and dry grinding, using them with a coolant or water can help extend their lifespan and prevent overheating.

It’s recommended to store the grinding wheels in a cool, dry place, away from direct sunlight. Keeping them in their original packaging can also protect them from environmental factors and potential damage.

Our grinding wheels are designed to be compatible with most conventional grinders. The included bushings allow for adjustments to different arbor sizes. If you’re unsure, please provide the specifications of your machine to our customer support for guidance.
We aim to offer comprehensive support and information to all our customers. Should you have any more questions or unique requirements, our team is always here to help.

The lifespan depends on usage, materials being ground, and proper maintenance. With regular use and proper care, customers generally find our grinding wheels last longer than many competing products.

Absolutely. Always ensure the machine is turned off and unplugged while changing the wheel. Wear safety gloves and ensure the new wheel is securely fastened before starting the machine again.

The nickel bonding is designed to be durable and resist common forms of corrosion. However, storing the wheel in a dry environment can further ensure its longevity.

The plastic hub is engineered to maintain a proper balance of the wheel during operation, ensuring smooth performance and reduced vibrations.

SMART CUT™ technology emphasizes the optimal distribution of diamonds on the wheel, ensuring consistent grinding, longer wheel life, and faster cutting speeds.

While we encourage recycling, you should check with local waste management or recycling centers about the best disposal methods for used grinding wheels.

Yes, especially the finer grit sizes, which are designed for detailed or precision grinding work.

The plastic hub is significantly lighter than traditional metal hubs, reducing the overall weight and strain on grinding machines.

The RPM usually decreases as the diameter of the grinding wheel increases. For a grinding wheel of around 6 to 8 inches typical RPM values range from 3,500 to 6,000 RPM depending on material. Softer materials might allow for higher RPMs, while harder materials might require slower RPMs for efficient grinding.

Water soluble coolants are often the most common coolants used for grinding. They are made by mixing water with a coolant concentrate. These coolants are known for their excellent cooling properties.

Dressing a grinding wheel involves the process of renewing the wheel’s surface to ensure it’s sharp and clean. This helps in maintaining the wheel’s performance, ensures precision grinding, and can extend the wheel’s lifespan.

Electroplated diamond grinding wheels have a single layer of diamond particles. While they don’t typically require frequent dressing like resin-bonded wheels, occasional dressing can help maintain optimal performance, especially if the wheel becomes glazed or loaded with material.

For electroplated diamond wheels, using a silicon carbide dressing stick or a softer, fine-grit diamond wheel can be effective.

Unlike other types of grinding wheels, electroplated diamond wheels don’t need frequent dressing. Dress only when you notice a decrease in grinding efficiency or when the surface becomes glazed or loaded.

Turn on the grinder and let it reach full speed. Hold the dressing stick flat against the wheel’s surface, ensuring you cover the entire wheel face. Move the stick back and forth until the wheel’s surface feels sharp and clean.

No. Dressing is for renewing the surface of the wheel. If your wheel has deep chips or cracks, it may be unsafe to use, and replacing the wheel is recommended.

Always ensure you wear safety glasses, and keep your fingers and hands away from the wheel’s surface. Dressing can produce dust, so consider using a dust mask if working in an enclosed space.

Dressing primarily focuses on renewing the wheel’s surface. While minor adjustments to the profile can sometimes be made, significant reshaping requires specialized tools and techniques.

After dressing, you might need to realign the tool rest or make other minor adjustments to maintain accuracy in your grinding tasks.

If the wheel feels smooth, it’s taking longer to grind, or you notice decreased grinding performance, it may be time to dress the wheel. Another indicator is if you see material buildup or a shiny glaze on the wheel’s surface.

Over-dressing can remove the diamond particles since they are only a single layer in electroplated wheels. If this happens, the wheel might become less efficient. Monitor its performance, and if grinding becomes inefficient, consider replacing the wheel.

Non-textured wheels offer a smooth and consistent grinding surface, which can result in a uniform finish. Textured wheels, on the other hand, might be designed to increase the rate of material removal or enhance cooling by allowing better water flow between the wheel and the workpiece.

Lifespan can vary based on various factors like usage, material being ground, and wheel quality. However, in general, non-textured wheels can wear more uniformly, potentially offering a longer lifespan. Textured wheels might wear unevenly due to the varied surface, but they might also allow for faster grinding in certain applications.

The plastic hub is significantly lighter than steel hubs. This makes the SMART CUT™ wheel more suitable for less powerful grinding machines and can reduce the overall wear on the grinder’s motor.

Steel hubs typically offer better overall balance due to their uniformity and weight. However, high-quality plastic hubs like those in the SMART CUT™ wheels are designed for good balance during operations.

The grinding efficiency isn’t solely determined by the hub material but also by the diamond grit, bonding method, and wheel design. However, steel hubs can handle more force and might be suitable for heavy-duty grinding tasks, while plastic hubs might be best for lighter tasks or precision grinding.

While specific prices vary, plastic hub wheels like the SMART CUT™ are often more cost-effective than their steel counterparts. However, users should also consider factors like lifespan, efficiency, and application suitability when evaluating cost.

Yes, the SMART CUT™ Electroplated Diamond Grinding Wheel is designed to be used on all conventional grinders made today, much like most steel hub wheels. However, always ensure the machine’s RPM ratings and other specifications are compatible with the chosen wheel.

Plastic hubs are more lightweight, resulting in reduced transportation emissions. Additionally, the SMART CUT™ wheels’ emphasis on being recyclable highlights an eco-friendly approach. Steel, while heavier, is also recyclable. Both materials have environmental merits, but specific environmental impact can vary based on manufacturing practices.

Steel hubs generally conduct heat better than plastic, aiding in heat dissipation. However, the overall heat management will also depend on factors like wheel design, coolant use, and grinding speed.

Both types of wheels require regular inspection for wear, damage, and balance. Steel hubs might be more resistant to physical impact, while plastic hubs might be more susceptible to damage from certain solvents or extreme temperatures. Always refer to the manufacturer’s care instructions.

A concave diamond grinding wheel has a curved or bowl-like shape, where the grinding surface is inwardly curved. This unique shape allows for specific grinding and shaping tasks that flat or convex wheels can’t perform.

Concave diamond grinding wheels are primarily used for:
Carving and shaping rounded grooves in gemstones and other hard materials.
Creating concave facets in gemstones for unique jewelry designs.
Grinding and shaping the insides of hollow tools or parts.

While flat and convex wheels are used for general grinding, shaping, and surface finishing tasks, concave wheels are specialized tools designed primarily for carving out rounded grooves or creating specific shapes that require an inward curve.

The advantages include:
Precision Grinding: The curved shape allows for precise carving of rounded shapes and grooves.
Unique Designs: It enables unique gemstone designs, especially in gemstone jewelry.
Efficiency: Achieving such shapes with flat or convex wheels would be more time-consuming and less precise.
Reduced Tool Requirement: Instead of using multiple tools for creating a curved design, a concave wheel can often achieve the desired result on its own.

While they can be used for some overlapping tasks, concave wheels are specialized tools. Using them for tasks suited for flat or convex wheels might not be efficient and can lead to uneven wear of the wheel.

Using concave wheels might require a more delicate touch, especially when working with gemstones. It’s essential to ensure even pressure and constantly check the depth and uniformity of the groove or shape being carved.

The size or curvature you need will depend on the specific application. Consider the size of the groove or shape you want to create and choose a wheel that matches those dimensions.

: General care, like regular cleaning and inspection for damage, is essential for all types of grinding wheels. Due to their shape, concave wheels might require more careful cleaning to ensure that all residue is removed from the curved surface.

Yes, the same type of coolant or lubrication can be used, but always refer to the manufacturer’s recommendations to ensure compatibility.
