Special Features of Vitrified CBN Mounted Points

For various types of CBN tools, Vitrified CBN mounted points provide excellent quality in terms of concentration/grit, shank, and dressing.

• Concentration or Grit

  The grit concentration varies considerably depending on the application done. It denotes the volume of ultrahard abrasive grain applied in the tool. This is a very important feature since it determines the effectiveness of the grinding.

• Shank

  For Vitrified CBN mounted points, a tungsten carbide shank is supplied. The carbide material provides greater elasticity which is three times greater than steel materials. With this, the deflection of the tools which is a result of grinding pressure is kept to a minimum. Here are some advantages of a tungsten carbide shank:

1. It reduces the spark out time which means a shorter grinding cycle.
2. It considerably improves the tool’s life.
3. It reduces tooling and setting costs.
4. It improves the surface finish of the workpiece.
5. It provides an improvement in workpiece geometry.

• Dressing

  This mounted point has quality dressing to achieve geometrical accuracy and to prevent the abrasive grain from getting dull. It also frees up the surface from loading and maintains a free cutting tool. Vitrified CBN mounted points should be dressed wet using ample coolant substance. There are various dressing methods used which depend on the hardness of the tool.

Suitable Materials for Vitrified CBN Mounted Points:

1. Steel
2. stainless steel
3. ultra-hard steel
4. reverted steel
5. aluminum alloy
6. magnesium alloy
7. titanium alloy
8. dental mold/resin grinder
9. glass and stone

Technical and Storing Tips for Vitrified CBN Mounted Points

To fully secure the safety of the operator and keep the tool from running efficiently, here are some tips you can take note of when using this mounted point.

Technical Tips:

• When you are using the tool for a faster grinding process, you can choose a medium to rougher grain size and grit level so you can meet the needed requirement and special usage. Just be careful not to get the surface too rough at the same time.
• To achieve faster grinding and finer grit, try to apply two or three grit as a group. You may use rough grit first in the grinding process, then followed by a finer grit.

Safe Storing Tips:

• To secure the tool and prevent it from getting worn out, make sure that you are storing it in a dry and spacious place. Make sure to keep it in a 10-30 degrees temperature and a highly ventilated condition. This is a big factor in decreasing density on the mounted points which prevents more damage.
• Use a shelf in arranging the mounted points. To keep your tools from accident incidents, placed the heavier mounted points at the bottom of the shelf, while the smaller and lighter mounted points should be placed at the top and middle part of the shelf. Organized the mounted points in their safest position to avoid distortion.
• For easy and accessible working, store your mounted points in a place that is easy to go in and will not create chaos on your other things. Place them in a more spacious and accessible area where you can roam around and do your work.

Vitrified CBN Mounted points have various applications which contribute a lot to grinding, polishing, dressing, and deburring fields.
