What Is a Diamond Rotary Dresser?
Grinding operations often work best with some form of wheel dressing to re-establish the wheel profile and/or recondition the wheel face. Wheel conditioning typically involves the sharpening and opening of the wheel face, while also removing dull abrasives, excessive bond, and workpiece material (loading). A sharp and open wheel face will allow maximum possible material-removal rates and reduced thermal stress on the workpiece. CDT engineers design each dresser to match your wheel topography so that it performs with superior strength and versatility. All are made with the highest quality CVD, natural diamond, synthetic diamond and combinations to maximize performance and roll life. Because they are custom manufactured, an abundance of configurations are possible.
Types of Diamond Rotary Dressers
There are two manufacturing methods for rotary dressers with several variations in setting/diamond application to best suit the customer application. Below are several examples:
1. Reverse Plated Diamond Roll
Manufactured with high accuracy molds and a tightly controlled electroplating process to deposit the nickel layer. The nickel layer holds the abrasive in place to allow for extremely complex profiles and tight tolerance work, which produce high quality surface finishes. Because of the accuracy on the front end of the process, these rolls require little to no surface conditioning, which leave sharp natural points for superior dressing, resulting in an open grinding wheel and lower grinding forces. Reverse plated rolls are ideal for continuous dress creep feed process, and complex forms like bearings, fuel injection, thread forms, and aerospace root forms.
2. Sintered Diamond Roll
Using a high temperature powdered metal process to create a tough tungsten matrix to secure the abrasive in the roll. This product is ideal for aggressive grinding and harsh working environment, while still holding tight profile tolerances and complex forms. These are all handset products, either pattern set or random set, to allow for a wide range of options on performance, surface finish, and roll life. Because of the manufacturing process, these rolls generally have shorter lead times and can usually be reworked to meet production demands. Sintered rolls are ideal for simple profile rolls to complex valve grinding assemblies.
3. Sintered CVD / Disc Dresser
These dressers use the same tough tungsten matrix as the standard Sintered rolls but are unique in the abrasive they are set with and how they are typically used. They are available using synthetic, natural, or CVD abrasive and can be set in combination to target specific performance, surface finish, and roll life. These are typically used to traverse across the grinding wheel to generate specific profiles and wheel conditions for open and free cutting grinding of the part. This style dresser is ideal for reconditioning, which can restore the roll to its original profile and tolerance in half the normal lead time and a fraction of the cost.
