Operations Manual

Main Overview


This manual is designed to give the operator a working understanding of how to operate your new CNC Centerless Grinder. The control is designed to simplify the operation of your Centerless Grinder high-end features. We have elected not to use g-codes to manipulate the servo axis. Instead, we use the combination of a simplified data entry routine with a graphic interface that the operator will find extremely easy to use.

Using a touch screen interface the operator simply touches the push button to start of stop a function or touch an edit field to change data, directly on the screen.

Each screen contains items that are used specifically for the function of the individual screen like starting and stopping motors, changing cycle modes, entering new feedrates and positions, etc.

There are other items that are used globally. This means that the same items are found on all of the screens. Primarily they are the machine state, cycle time, and date and time at the top of the screen, the axis position, cycle status, current feedrate, and wheel speed on the right side of the screen.
