Precision CNC Multi-Process Vertical Grinding

What is Vertical Grinding?

CNC Cylindrical Multi-Process Vertical Grinding is a grinding method in which the workpiece is held upright in a rotating chuck and multiple precision grinding processes such us OD grinding, ID grinding and face grinding can be done in a single chucking. This kind of grinding method is best suited when relatively large diameters on heavy parts need to be precision ground. However, internal diameters as small as 2 inches can be ground.

Multi-Process CNC Vertica ID, OD and Face Grinding Capabilities

Our Taiyo Koki Vertical Mate 85 Multi-process vertical grinding machine can grind internal diameters from 2 inches to 31.5 inches by 19.1 inches in length.

This machine can also grind external diameters from less than 1 inch to up to 31.5 inches and lengths of 19.1 inches.

  • ATC (Automatic Tool Changer) magazine equipped with up to six grinding wheels. Wheel diameters φ2.0 – φ12.0 inches
  • Automatically changes the grinding angle of the grinding wheel to grind ID/OD or faces
  • Touch sensor for measuring ID/OD and faces
  • 15 horse-power wheel spindle
  • The maximum load capacity of our Veridical Mate 85 is 1,540 lbs.
  • MAPPS ⅣB High-Performance Operating System equipped with GriPSⅡconversational grinding program
  • Roundness error of less than 1 µm (less than ±0.000039 inch)
  • Rotary and single point dressers
  • A workpiece with multiple grinding operations can be finished in one chucking

Benefits of Vertical Grinding vs Horizontal Grinding

Here are some of the benefits of Cylindrical Vertical Grinding vs Cylindrical Horizontal Grinding:

  • Can achieve roundness of less than 1 µm or 0.000004 of an inch
  • By using the weight of the workpiece, fixturing a workpiece for vertical grinding only requires enough clamping force to resist grinding force as opposed to horizontal grinding which requires extra clamping force for preventing the workpiece from falling out of the chuck. Using excessive clamping force can, for example, create distortion, poor surface finish, and/or roundness problems.
  • Easy loading and unloading of workpiece
  • Grinding multiple ODs, IDs and faces in a single chucking results in high grinding accuracy
  • Be able to maintain concentricity and runout between IDs and ODs more accurately
  • Perpendicularity of the ID and OD to the face can also be held very accurately
  • Produce parts more efficiently
  • Reduces the time wasted doing multiple setups
  • Fewer setups reduces part handling, fewer machines are needed, and shorter lead-times
  • Lower labor cost
  • This machine weights nearly 29,000. The rigid structural design of this machine helps eliminate vibration and distortion
