The Brief:

CNC bore the pre-welded bore back to standard

Three bores on the 3-meter diameter, 4-tonne unit was performed using the Monti Mill and a boring bar

The Solution:

The machining process for the three bores on the 3-meter diameter, 4-tonne unit was performed using the Monti Mill and a boring bar. The following technical steps were involved:

Machine setup: The Monti Mill was calibrated to ensure its accuracy and capacity for handling the unit’s size and weight.

Secure mounting: Appropriate fixtures, clamps, and alignment techniques were utilized to securely mount the unit on the Monti Mill, minimizing vibrations during machining.

Boring bar selection: A suitable boring bar was chosen that aligned with the customer’s specified tolerances and sizes for the bores. The unit’s material properties and the desired machining outcomes were considered.

Machining parameters: The optimal cutting speed, feed rate, and depth of cut were set on the Monti Mill based on the unit’s material characteristics and the required precision. Adherence to the customer’s specifications was ensured.

Bore machining: The machining process was initiated by using the Monti Mill and the selected boring bar to remove material and create the desired bores. The process was closely monitored to maintain accuracy and make necessary adjustments if required.

Dimensional verification: Precision measuring instruments such as bore gauges or micrometres were used to measure and verify the dimensions of the machined bores. It was ensured that they conformed to the customer’s specified tolerances and sizes.

Repeat machining: The same machining process was repeated for the remaining two bores, ensuring consistent precision and adherence to the established setup.
