产品概述
Anchor UNICORN CVD dressing tools are engineered for high-precision profiling grinding, split into two core lines: multi-pillar CVD dressers and CVD roller dressers. Different from traditional single-point natural diamond dressers, they adopt arrayed CVD diamond pillars for uniform, predictable wear and consistent profile accuracy in mass production, with parallelism, verticality and runout tolerance controlled within 5μm.
Compatible with alumina, silicon carbide, sol-gel ceramic, diamond and CBN grinding wheels, they fit cylindrical, centerless, form, gear and linear guide grinders for precision parts including gears, linear guides, ball screws, bearings and cutting tools. Standard 3/4/5-pillar models are matched by wheel OD, thickness and abrasive type; custom pillar count, angle, radius and overall dimensions are supported to meet mass production and special profiling demands. Under identical test conditions, service life hits 187% of conventional single-point dressers, drastically cutting replacement frequency and total consumable cost.
Two Core Product Lines
- CVD Multi-Pillar Dresser
Standard models MR-3/MR-4/MR-5/MR-5S/MR-7/MR-7V/MR-8/MR-10 include flat top, angular cone top, taper shank and straight shank designs with 3~5 CVD pillars optional.
Designed for surface, cylindrical and end-face dressing of small & medium wheels, easy to operate without high operator experience. Even CVD pillar wear avoids single-point chipping and sudden profile shift, stabilizing workpiece Ra for continuous medium-volume precision grinding. - CVD Roller Dresser
Monolithic CVD diamond rim structure with custom outer diameter 40~150mm, available in single bore and multi-bolt mounting base.
Enables full rapid profiling for wide & large-diameter wheels, replicating complete wheel profile in one pass with micron-level geometric tolerance. Ideal for 24/7 heavy-duty mass production lines, outstanding wear resistance for SiC and high-hardness ceramic wheels, minimizing machine downtime for dressing.
Selection Guidance
- Pillar Quantity Matching Rule
Pillar quantity is determined by wheel OD and thickness: 3 pillars for OD ≤200mm; 4 pillars for 200~400mm; 5 pillars for 400~700mm. When dressing SiC C/GC or sol-gel SG/CX wheels, upgrade to one higher pillar grade for extended service life. More pillars reduce single-pillar load and extend total lifespan. - Parameter Tolerance Standard
Uniform precision tolerance for all CVD dressers: parallelism ≤5μm, verticality ≤5μm, radial runout ≤5μm. 100% inspection before delivery to guarantee consistent wheel profile and eliminate workpiece dimension deviation & poor surface roughness.
Core Advantages vs Traditional Single-Point Diamond Dresser
| Comparison Item | UNICORN CVD Dresser | Conventional Single-Point Diamond Dresser |
| Raw Material | Uniform CVD diamond pillars | Natural / Synthetic single diamond grain |
| Hardness Feature | Moderate hardness, balanced wear speed | High hardness, uneven sudden grain loss |
| Consistency | Stable wear, uniform profile, high repeatability | Natural diamond quality inconsistency, easy tip collapse |
| Operation | Simple operation, low requirement for operator skill | Highly dependent on dressing experience |
| Service Life | 187% service life under identical working conditions | Short lifespan, frequent replacement |
| Comprehensive Cost | Higher unit price, lower total production cost | Low unit price, high downtime & replacement cost |
Standard Operation & Installation Precautions
- Installation rule: CVD pillar contact surface must stay perpendicular (90°) to wheel face for full uniform load and avoid one-sided partial wear.
- Angle adjustment: Tilt only the dresser base if angular dressing is needed; keep pillar end face vertical to wheel, never slant pillars against grinding wheel.
- Dressing parameters: Avoid heavy single-pass stock removal; adopt multiple light passes to reduce impact wear on CVD pillars.
- Process compatibility: Suitable for both rough and fine grinding. Boost removal rate for rough dressing and stabilize mirror Ra finish for fine grinding, ideal for high-gloss parts like gears, linear guides and ball screws.
Application Scope
- Compatible Wheels: Alumina, silicon carbide, sol-gel ceramic, diamond & CBN superabrasive wheels
- Matching Machines: Cylindrical grinders, centerless grinders, form grinders, gear grinders, linear guide grinders, angular traverse grinders
- Machined Workpieces: Gears, linear guides, ball screws, precision bearings, carbide cutting tools, hydraulic precision components
- Dressing Processes: Rough wheel profiling, fine sharpening, form profile replication, fine edge dressing for ultra-thin wheels
