Product Overview of Straight Grinding Wheel
This straight grinding wheel is specially designed for toolroom applications and is suitable for tool grinders, surface grinding machines, and universal grinding machines. It delivers stable and efficient grinding performance for sharpening milling cutters, drills, turning tools, and for profile grinding of precision components.
Typical Applications of Straight Grinding Wheel
- Resharpening and maintenance of cutting tools, including end mills, reamers, drills, and taps
- Precision grinding of tool steel, mold steel, and high-speed steel (HSS)
- Rough and finish grinding of carbide-tipped tools
- Surface grinding of gauges, fixtures, and precision components

Key Advantages of Toolroom Grinding Wheel
High Dimensional Accuracy
Strict tolerance control on both outer diameter and bore ensures minimal runout after installation, meeting the demanding precision requirements of toolroom grinding.
Excellent Self-Sharpening Performance
Premium abrasive grains combined with optimized hardness allow dull grains to break away at the proper time, reducing dressing frequency and improving tool sharpening efficiency.
Cooler Grinding Operation
The optimized porous structure promotes effective chip removal and heat dissipation, helping prevent edge burning and preserving the hardness and service life of cutting tools.
Superior Shape Retention
The vitrified bond provides strong support to the abrasive grains, allowing the wheel to maintain its profile during slot grinding and complex contour grinding applications.
Operating Recommendations of Vitrified Grinding Wheel
- Recommended Wheel Speed: 35–50 m/s (Always verify the maximum spindle speed of the grinding machine before operation)
- Dressing Tools: Single-point diamond dresser or diamond dressing block
- Coolant: Water-based or oil-based coolant is recommended to improve surface finish and reduce the risk of thermal cracking
- Storage Conditions: Store in a dry, vibration-free environment and protect from moisture, impacts, and improper handling
