CNC Milling is at the heart of what we do at Presto.

Our expertise is in machined aluminium parts a high proportion of which are visible parts for example front panels and enclosures. We are set up to accommodate batch sizes from 10 to 1,000.

Constant investment in new vertical machining centres together with refinement of our processes means that we achieve high throughput, quality and accuracy for our customers. All our machining centres have 4th Axis capability which enables us to minimise the number of interventions and improve accuracy of the component.

High quality traceable raw materials are sourced from European suppliers utilising best-in-class mining and smelting operations.

All components are programmed on FeatureCAM® from customer CAD/CAM models. We are able to convert drawings received in most other programmes to be compatible with FeatureCAM®.

What is CNC Milling

Computer Numerical Control (CNC) has been incorporated into a variety of technologies and machinery and one of the most common is CNC Milling.

CNC Milling is a specific type of CNC Machining. Milling is a process similar to drilling or cutting and utilises a cylindrical cutting tool that can rotate in various directions and move along multiple axes. It is capable of creating a wide variety of shapes, slots and holes which will result in a precision part. To form the finished part, the cutting process can be started from a solid block, pre-machined part, casting or forgings. CNC Milling can also be used to create industrial engraving.

CNC Milling machines are often grouped by the number of axes on which they can operate. Each axis is labelled by letter, for example, X and Y axes represent the horizontal movement of the Mill’s work piece. The Z axis designates vertical movement and W axis represents the diagonal movement across the vertical plane.

The majority of CNC Milling machines offer from 3 to 5 axes. Nowadays Milling machines are programmed with computer-aided manufacturing (CAM) technology and can create shapes that are virtually impossible to produce with manual tooling techniques. Water is an integral part of the process as metal becomes extremely hot during the cutting process and water avoids it overheating.

To achieve the finished part the CNC Milling process is managed by a skilled CNC Machinist who undertakes the following activities:-

  • Interpret engineering drawings and follow the specifications
  • Generate a process and programme (logical process plan) with a CAD/CAM system and/or G and M-codes
  • Set up the tooling, work holding device and work piece on the CNC Milling machine
  • Manipulate cutting conditions, based on the properties of the material and tooling used
  • Operate, inspect and maintain the accuracy of dimensions within the specified tolerances
  • Optimize the process taking into account the production type: large quantities of one part, small batches or one-of-a-kind items.

At Presto Engineering we specialise in working with aluminium. However, CNC Milling can be used to shape most metals and other solid materials.
