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.
Key Terminology for the Article
- cnc grinding machine:CNC (Computerized Numerical Control) grinding is a machine that automatically performs a series of operations from the mounting to the removal of a workpiece, including dressing, grinding, and measurement.
A CNC grinding machine with a tilting spindle can perform internal, external, and end face grinding in a single setup. This also makes it possible to perform profile grinding of complex shapes, which is difficult for conventional grinding machines. - Surface Grinding:Surface grinding is a machining method that uses a rotating grinding wheel on a surface grinder to make the surface of a workpiece perfectly flat. Unlike the rough finish often imagined from general cutting processes, surface grinding can achieve extremely high precision in terms of flatness, parallelism, face roughness, and dimensions.
By carefully selecting the right grinding wheel and cutting fluid, we can machine a wide range of materials, from soft materials like aluminum to very hard ones like quenched steel that has been hardened through heat treatment..
