Grinding Wheel Dressers: Why Does Your Grinding Wheel Need One?
Over time, grinding wheels will become glazed with buildup or worn down from use. This causes them to lose their cutting ability and can cause accuracy and part characteristic issues to your workpiece. Dressing the wheel removes this build-up or wear, restores the wheel’s cutting ability, and helps to prevent damage.
Below we explain everything you need to know about grinding wheel dressers.
What Is Grinding Wheel Dressing?
Grinding wheel dressing is the process of refreshing the abrasive surface of a wheel to clean or true it. The three main types of grinding wheel dressers are vitrified, diamond, and CBN (cubic boron nitride).
Dressing a grinding wheel is important because it:
- Removes built-up material from the surface of the wheel
- Restores the wheel to its original shape
- Provides a fresh, sharp cutting surface
- Increases wheel life
When Is a Grinding Wheel Considered Worn Out?
The main cause of grinding wheel wear is exposure to excessive heat and material build-up. Excessive vibration during operation can lead to faster wear. Other causes include improper mounting, imbalanced wheels, poor dressing techniques, or improper storage.
A worn out grinding wheel can lead to several common problems
- Abrasive particles can become embedded in the wheel, causing it to become dull.
- The wheel can become glazed from use, making it less effective.
- The wheel can develop flat spots from too much pressure being applied in one area.
What Are the Different Types of Grinding Wheel Dressers?
There are several different types of grinding wheel dressers. Some of the important ones are:
- Diamond dressers:These dressers use diamonds mounted on a shank to clean and sharpen your grinding wheels. They are the most common type of dresser and can be used on all types of wheels.
- Silicon carbide dressers:These dressers are made of a harder abrasive than diamond dressers, making them ideal for dressing harder grinding wheels.
- Single-point dressers:These dressers have a single point that is used to clean and sharpen your grinding wheels. They are not as common as diamond or silicon carbide dressers but can be used on all types of wheels.
- Multi-point dressers:These dressers have multiple points that are used to clean and sharpen your grinding wheels. They are not as common as single-point dressers but can be used on all types of wheels.
What Should You Consider when Choosing a Grinder Dressing Tool?
To choose the right dressing tool, you need to consider the type of wheel you’re using, the material you’re dressing, and the condition of the wheel.
Vitrified dressers are used on most conventional wheels and are made from a combination of abrasives and bonding agents. The abrasives are usually aluminum oxide or silicon carbide. Diamond dressers are used on diamond and CBN wheels. They can be either natural or synthetic diamonds. And CBN dressers are used on CBN wheels and are made from a cubic boron nitride crystal.
The type of material you’re dressing will also affect your choice of tool. If you’re dressing a soft material, such as aluminum oxide, you should use a harder tool, such as diamond or CBN. If you’re dressing a harder material, such as carbide, you should use a softer tool, such as vitrified.
Finally, you need to consider the condition of the wheel. If the wheel is new or in good condition, you should use a more aggressive dressing tool. If the wheel is worn or damaged, you should use a less aggressive tool.
Once you’ve selected the right dressing tool, you’re ready to dress your grinding wheel. Follow the manufacturer’s instructions for safe and effective use.
With proper dressing, your grinding wheel will last longer and perform better. So, don’t neglect this important step in the maintenance of your equipment.
How to Use a Grinder Dressing Tool Effectively
There are a few things you need to keep in mind when using a grinder dressing tool:
- Always dress the wheel before starting your grinding operation.
- Follow the manufacturer’s instructions for safe and effective use.
- Use light pressure when dressing the wheel. Too much pressure can damage the wheel.
- Dress the entire circumference of the wheel, not just the area you’re grinding.
- After dressing the wheel, clean off any debris before starting your grinding operation.
By following these tips, you’ll get the most out of your grinder dressing tool and keep your equipment in top condition.
As with all tools and machines, safety should always be your number one priority. Be sure to read the manufacturer’s instructions carefully and always wear proper safety gear when using a grinder or dressing tool.
