Diamond Rotary Dressers by Type

Industry's increasing demand for high-accuracy, high-speed production has fostered a new branch of engineering technology to ensure grinding wheels are maintained in optimum condition. Diamond Rotary Dressers are now recognised as the most efficient and economic means of dressing and truing grinding wheels to the correct form, tolerance and condition. Their use is growing rapidly in the manufacture of components for automotive, aerospace, power generation, machine tool and precision engineering industries.

Leading in innovation

At Continental Diamond Tool Limited, we have been a frontrunner for decades in innovating rotary dresser technology. As far back as 1995, as Consort Precision Diamond Company, we won industry awards for our development of the high speed plating process which dramatically reduced previous lengthy plating times and is still in use today. We proudly holds the ISO 9001:2015 Registration Certificate for its Quality Management Systems, and we are continuously innovating to increase the efficiency and cost effectiveness of this industry-changing technology.

OUR FOUR MAIN PROCESSES

There are four distinct methods we use in the manufacture of our diamond rotary dressers: reverse plated, hand-set sintered, cvd sintered, and random set sintered. Each has its own benefits, as outlined below.

 

Type 1 - Reverse-Plated

The High Accuracy dresser

Reverse Plated Dressers are selected where high accuracy of profile detail is required together with a correspondingly high quality surface finish on the component.

Accuracy is achieved by centrifugal dispersion of the specially selected diamonds onto the walls of a mould. These are secured by our electro-deposition process that has won acclaim through the acquisition of industry awards, thereby achieving the short lead times so often required by customers.

The electro-deposition process is stable and unaffected by shrinkage, which results in Rotary Diamond Dressers of exceptional accuracy.

Tolerance Detail

General Surface Finish Produced: 0.4uM. 16 C.L.A.

Typical Applications

  • Turbine Blade - Fir Tree Root Form

  • Cam Grinding

  • Bearing Industry

  • Ball Joints

  • Needle Injectors

 
 

Type 2 - Handset Sintered Dressers

A CONSORT PRECISION™ SPECIALTY

Of all the rotary dressers for which the Consort Precision name is known, Handset Sintered Dressers are our most popular type. These custom diamond rotary dressers cover many applications where robustness is required and the general tolerance is open.

As the name implies, diamonds are selected and set by hand in a mould, then secured in position by sintering in a tungsten based matrix. Allowances are made for consequential shrinkage to bring the finished dresser within specification tolerances.

Tolerance Detail

General Surface Finish Produced: 0.8uM. 32 C.L.A.

Typical Applications

  • Turbine Blade

  • Automobile Valves

  • Crankshafts

 
 

type 3 - CVD Sintered

THE High Performance Dresser

Our CVD sintered rotary diamond dressers have very high thermal oxidation resistance and other excellent thermal properties. CVD is perfect for secure mounting with traditional non-ferrous metal sintering. CVD sintered rotary diamond dressers can also be brazed onto a dresser body using an active braze alloy in a non-oxidizing environment.

Benefits

  • Highly resistant to chipping and fracture

  • Wears evenly over the dresser's entire length

  • Performs regardless of dressing orientation

  • Outstanding thermal stability

CVD diamond can be manufactured in a multitude of shapes, sizes, thicknesses and grades giving engineers great flexibility with this material's extreme properties. 

Dimensions

Our CVD diamond dressers can be ordered in all the standard rectangular dimensions in various lengths and square, but we also specialize in supplying non-standard custom dimensions upon request.

Typical Applications

  • Metal matrix composites

  • Aluminium alloys

  • Glass-reinforced plastics

  • Carbon fibre-based materials

  • Plastics and rubbers

  • Graphite

 
 

type 4 - random set sintered

The dresser FOR QUICK DELIVERY

Random Set Sintered Dressers are most suitable where openness is required, coupled with a tight form and improved surface finish. 

Very often selected diamonds are strategically placed in the mould to support the form in vulnerable areas. The remaining area is then in-filled by centrifugal dispersion of diamonds and sintered.

Random Set Sintered Dressers have the advantage that they can be delivered quickly to meet urgent customer requirements.

Tolerance Detail

General Surface Finish Produced 0.4 uM. 16 C.L.A.

Typical Applications

  • Automobile Valves

  • Turbine Root Forms

  • Flute Grinding

CHOOSING THE RIGHT DRESSER TYPE

Within each of these categories there are many further variables of appropriate diamonds and setting patterns to consider when ordering dressers of this type. Specialist techniques need specialist suppliers which is why we established our Consort Precision Diamond Rotary Dresser custom product line. Since 1984, we have dedicated substantial resources to developing the finest Diamond Rotary Dressers and support services available.

At Continental Diamond Tool Limited, we focus predominately on the design, development, manufacture, install and maintenance of Rotary Diamond Dressers. And we think that gives us a unique commitment to provide our customers with the best technology can offer.

If an application calls for a Diamond Rotary Dresser, Continental Diamond Tool will provide the best tool for the job. Contact us for a free consultation and quote.
