Product Description
WC-Ni Guide Blocks Ultra-Precision Linear Guide Component For Sensitive Environments
Non-Magnetic Tungsten Carbide Precision Guide Block
Engineered for Perfect Linearity Where Magnetic Fields Are the Enemy.
In the realm of ultra-precision machinery—from medical MRI scanners to semiconductor lithography—conventional guide components introduce risk. Magnetic interference can distort sensitive measurements, while wear compromises accuracy over time. Our Non-Magnetic Tungsten Carbide Guide Block is the definitive solution. Crafted from specialized WC-Ni alloy and finished to optical-grade flatness, it delivers absolute magnetic neutrality, exceptional wear resistance, and unparalleled geometric stability for the most demanding linear motion applications.
The Non-Magnetic Imperative
True performance begins at the material level. By utilizing a Nickel (Ni) based binder instead of Cobalt (Co), we eliminate ferromagnetism from the tungsten carbide matrix. This ensures your sensitive equipment operates without magnetic "noise" or attraction.
Material Properties Comparison
| Material Property | Our WC-Ni Guide Block | Benefit to Your Application |
|---|---|---|
| Magnetic Permeability (µ) | < 1.002 (Certified) | Zero interference in MRI, electron microscopes, and sensitive lab environments. |
| Hardness | 90 - 92 HRA | Exceptional wear life, outperforming tool steel by a factor of 50x or more, minimizing maintenance. |
| Compressive Strength | > 4500 MPa | Withstands high preload forces without deformation, ensuring long-term accuracy. |
| Thermal Expansion Coefficient | ~5.5 x 10⁻⁶/K | Extreme dimensional stability across temperature fluctuations common in precision systems. |
| Corrosion Resistance | Excellent | Resists coolants and mild chemicals, suitable for cleanroom and medical use. |
Standard Features
- Ultra-Flat Guide Surfaces: Machined and lapped to flatness and parallelism better than 2 µm over the entire length.
- Precision Mounting Holes: Tapped or through-holes with tight positional tolerances (±0.005mm) for flawless integration.
- Critical Edge Preparation: All edges are precision broken or chamfered to prevent chipping and ensure safety.
- Surface Finish: Guide surfaces can be finished from Ra 0.4 µm (ground) to Ra < 0.05 µm (super-finished/lapped) for optimal sliding characteristics.
Common Configurations (Fully Customizable)
| Type | Description | Best For |
|---|---|---|
| Linear Guide Block | Rectangular block with one or more precision-ground guiding faces. | Building custom slides, Z-axis stages, or upgrading existing systems. |
| Dovetail Guide Block | Features an integrated male or female dovetail for robust, high-stiffness linear motion. | High-load instrument bases, traditional machine tool ways. |
| Vee Guide Block | Includes a precision V-groove for guiding on round shafts or as part of a kinematic mount. | Optical alignment systems, rotary-to-linear guidance. |
Applications
This component is critical in industries where precision and non-magnetic properties are non-negotiable.
- Medical & Analytical Imaging: MRI patient bed guides, CT/PET scanner gantry components. Non-magnetic property is safety-critical.
