Durable Dressing Solutions
Type 1 – Reverse Plated Dressers
The High-Accuracy Dresser
Reverse plated dressers are chosen where maximum profile accuracy and superior surface finish are essential. Diamonds are deposited onto mould walls through centrifugal dispersion and secured by a stable electro-deposition process, ensuring dimensional precision unaffected by shrinkage.
Applications:
- Turbine blades
- Cam grinding
- Bearing industry
- Ball joints
- Needle injectors
Type 2 – Handset Sintered Dressers
The Robust Dresser
The most widely used rotary dresser, handset sintered types are valued for their robustness and adaptability. Diamonds are hand-selected and set in a mould, then bonded in a tungsten-based matrix by sintering. Dimensional allowances are included to compensate for shrinkage, providing consistent tolerance compliance.
Applications
- Turbine blades
- Automotive valves
- Crankshafts
- CNC dressing
Type 3 – CVD Sintered Dressers
The High-Performance Dresser
CVD (Chemical Vapor Deposition) sintered rotary diamond dressers combine extreme thermal stability with resistance to chipping and fracture. They wear uniformly and can be brazed or sintered into dresser bodies. The flexibility of CVD manufacturing allows for a wide range of shapes and grades, giving engineers maximum design freedom.
Benefits:
- Excellent thermal stability and oxidation resistance
- Even wear across dresser length
- High resistance to fracture
- Effective in any dressing orientation
Applications
- Form dressing
- Dressing of CBN grinding wheels
- Applications requiring superior surface finishes
Type 4 – Random Set Sintered Dressers
The Flexible Dresser
Random set sintered dressers are ideal where a combination of openness, tight form, and improved surface finish is required. Diamonds are selectively positioned in vulnerable areas, with remaining zones filled by centrifugal dispersion, creating a durable yet versatile dresser. These can also be quickly manufactured to meet urgent needs.
Characteristics / Features:
- Resin–metal synergy with balanced sharpness and durability.
- Longer lifespan than resin bonds, sharper cutting than metal bonds.
- Controlled chip evacuation and grinding forces.
- Customizable structure for different applications.
Applications
- Automatic valves
- Turbine root forms
- Flute grinding
- Turbine blades
- Cutting tools
Diamond Stationary Dressers
Extra endurance and long-lasting performance for versatile applications.
Stationary diamond dressers provide durable dressing solutions for a wide variety of grinding applications. With diameters available up to 355 mm (14”), they are designed for both wet and dry grinding environments, offering long life with reduced dressing frequency. The construction allows efficient heat dissipation, ensuring stable dressing performance even under demanding conditions.
