Grinding a Housing Flange on a Vertical CNC Grinder

Here are some free images from a job where we performed surface grinding on the end face of a housing flange using a Vertical CNC Grinding Machine.

A CNC grinding machine with a tilting spindle can complete internal diameter, external diameter, and end face grinding in a single setup (one chucking). This makes it easier to achieve high precision in terms of concentricity, perpendicularity, and parallelism.

On the other hand, since it cannot be held between two centers or supported with a steady rest, it has the disadvantage of difficulty in securing rigidity for long workpieces.

However, a single machine can perform what traditionally required three different machines. This significantly reduces setup times and allows for longer processing runs, making unmanned operation possible.
