Recognised by our customers as being an outstanding supplier, Milltech Precision Engineering has been offering affordable state-of-the-art CNC machining services since 1991. From our CNC Machining Shop in Norwich, we provide machined components to customers in Norfolk and throughout the UK.

With the ability to offer low and high volume batches, as well as prototyping services, we have become distinguished within industry for providing customers with ready to use precision machined components.

Looking for CNC Machined Parts?

Our CNC machine shop comprises of both CNC Milling and CNC Turning, both highly technical fields in their own right. 

We operate over 30 vertical and horizontal 3, 4 and 5-axis machining centres over 2 sites allowing us to provide extensive CNC machining services with the ability to stock and deliver parts when our customers require. This flexibility and sophisticated capacity is supported by the usual complement of manual machining capabilities.

Through a highly skilled workforce and continuous investment in the latest technologies, our comprehensive CNC machining shop are able to handle the most challenging of designs delivered on time and to a high standard of quality.

We are proud our CNC machining shop has ISO 9001:2015 accreditation, the internationally recognised quality management standard, which helps assure ourselves, as well as our customers, that we continue to deliver high quality machined components.

CNC Machining FAQ’s

What is CNC Precision Machining?

Precision means the quality or condition of being exact or accurate.

CNC Machining (Computer Numerical Control)  is the manufacturing process in which pre-programmed software is executed on a machining centre without an operator directly controlling the machine.

As CNC allows for the machining of material with the precision of one quarter the width of a human hair, the two terms are often mistakenly considered synonymous.

When was CNC Machining Invented?

Richard Kegg is widely considered to have developed the first CNC Milling machine in 1952.

Whilst there were pre-cursors to his design, for example the Industrial Revolution gave birth to first industrial machines with a focus on ensuring precision and repeatability, the art of using a motor to control position of a machine tool is credited to both Richard Kegg and MIT.

CNC machines became popular in the 60s and 70s as punch tape machining previously used was replaced with computer numerical control.

What is the process of CNC Machining?

CNC Machining involves a simple five step process:

  1. Designing a CAD model using the customer drawing
  2. Converting the file for executing on a CNC machine
  3. Loading, setting and preparing the CNC machine for operation
  4. Executing the machine operation and
  5. Send completed part to Quality Team to ensure compliance with original drawing.

What are the benefits of CNC Machining?

Primarily, precision. By having the ability to machine within a quarter of a hairs width, the accuracy of a CNC machine makes it an invaluable tool for any manufacturer looking to rapidly create parts with precision and consistency.

Is CNC Machining Expensive?

CNC Machining is a highly cost effective manufacturing operation. Generally, CNC machining is the most efficient solution to ensure repeatable precision for large volume batches or whenever precision is paramount, for example, one-off components. Using economies of scale, customers are able to benefit from reduced per unit cost when ordering in large volumes.

CNC machining is usually costed based on:

  • Raw materials
  • Any fixtures to fasten part during machining operations
  • Machine operation costs which is dependent on time per part

Typically, the CNC machining labour cost is billed at a rate of £45/hour.
