In precision grinding, the performance of grinding wheels is critical to achieving high-quality surface finishes and optimal processing efficiency. As grinding technology continues to evolve toward higher precision and productivity, traditional dressing tools often fall short in providing the precise control required for advanced wheel topography. Diamond dressing tools, with their superior structure and performance, have become essential for achieving exceptional grinding accuracy.
I. Structure and Application Scope
1. Core Structure
- Diamond Tip: Available in both natural and synthetic diamond types. Natural diamond offers exceptional hardness and wear resistance, making it ideal for high-precision dressing tasks. Synthetic diamond provides a cost-effective solution for general applications, effectively removing worn abrasive grains and debris from wheel pores to restore cutting performance.
- Shank Body: Manufactured from durable metal, the shank provides robust support for the diamond tip and ensures secure clamping. Its design minimizes loosening and vibration during operation, contributing to stable and reliable performance.
2. Application Scope
- Compatible Grinding Wheels: Suitable for ceramic-bonded wheels, resin-bonded wheels, and wheels made from alumina (such as corundum) or GC abrasives (green silicon carbide). Particularly effective for dressing high-hardness, low-wear-rate grinding wheels.
- Compatible Equipment: Works with a wide range of grinding machines, including cylindrical grinders, internal grinders, and centerless grinders. Ideal for various applications such as external cylindrical grinding, internal cylindrical grinding, and centerless grinding.
II. Shank Structures and Compatible Fixtures
The design of the shank directly influences clamping accuracy. Different shank structures require specific fixtures to ensure efficient and precise operation:
1. Standard Cylindrical Shank
- Features: Simple cylindrical design for broad compatibility and easy installation and removal.
- Compatible Fixtures:
- Drill Press Vise: Suitable for general grinding applications where clamping accuracy of ≤ 0.05mm is acceptable. Provides quick fixation and reduces vibration, though not recommended for high-precision dressing.
- Hydraulic Puller: Utilizes hydraulic pressure for even, adjustable clamping force. Best for dressing tools with shank diameters ≥ 10mm, reducing clamping stress and supporting medium-precision machining requirements.
2. Shank with Positioning Platforms
- Features: Incorporates four axial positioning platforms machined into the circular shank, achieving positioning accuracy of ≤ 0.005mm.
- Compatible Fixtures: Requires specialized fixtures with matching grooves for face-to-face contact. This configuration prevents radial rotation and vibration, making it suitable for high-precision grinding tasks such as bearing rollers and precision molds. Ensures wheel roundness error remains within ≤ 0.002mm.
