Materials and Structure
Vitrified bond with White Fused Alumina (WA) abrasive, known for its purity and hardness. The optional SG (ceramic alumina) abrasive provides enhanced micro-crystalline structure for superior performance. Structure number adjustable from 0 to 14.
Applications
Ideal for precision roll grinding in manufacturing, offering excellent surface finish and consistency on rolls made of hardened steels and other materials.
Customization
We can customize the abrasive type (WA or SG), dimensions, grain size, hardness, and structure to match your specific roll grinding requirements.
FAQ
Can I use this wheel for grinding chilled cast iron rolls?
Yes, with appropriate grain and hardness selection. Please consult our engineering team.
What is the advantage of SG over WA?
SG offers higher toughness and self-sharpening, which can result in longer wheel life and less dressing frequency in heavy-duty applications.
Are custom specifications available?
Yes, we offer customization in dimensions, abrasive type, grain, hardness, and structure.
What is the delivery time?
Delivery time depends on the specific configuration. Please contact us for accurate lead time.
Do you provide technical support?
Our R&D team with 6 engineers can provide technical guidance for wheel selection and optimization.
