The solar panel system here at GW Martin has been running for 11 years!

Our busy factory uses a lot of electricity, so we’ve always been keen to explore ways in which we could reduce our impact on the environment. When taking into account our large roof area, it seemed a no brainer to make the most of this space, so we decided to install a 150kW Solar PV system back in 2013.

Since then, the results have been brilliant…

Over the last 11 years, we’ve generated 1.2 million kWh of power. This is equivalent to saving 470 tonnes in CO2 emissions, or planting 14,000 trees.

Most of the power generated has been used right here at our factory in Eastleigh, Hampshire to help us make over 10 million precision machined components. And what we haven’t used has been exported back to the grid. In fact, the 300,000 kWh that we’ve exported is enough to fuel making around 5 million cups of tea for British manufacturers!

Coupling our solar power system with other energy saving initiatives such as air source heating and LED lighting, we have been able to dramatically reduce our energy usage and carbon footprint. All of this helps us to provide a sustainable supply of machined parts for our customers and, in turn, supports our ISO14001 accreditation too.

How does CNC machining work?

CNC machining, short for Computer Numerical Control machining, is renowned for being one of the most popular high-tech methods of digital manufacturing that has completely transformed the engineering industry.

In this blog, we’ll explore how CNC machining works and the benefits of using CNC machining for your next project:

What is CNC machining?

CNC machining is a manufacturing process in which pre-programmed computer software automates, monitors and controls the movement of CNC machinery.

Unlike 3D printing, which builds objects layer-by-layer, CNC machining is a form of subtractive manufacturing, using written code to remove material and shape the final product.

How CNC machining works

CNC machining makes pre-programming the machine’s speed and position functions possible, running them through software in consistent cycles. The process includes:

Step 1: Designing the part

The first step involves creating a detailed 2D or 3D design of the part to be manufactured using CAD (Computer-Aided Design) software, which acts as a blueprint for the CNC machine.

Step 2: Converting to a CNC programme

Programmers convert the CAD design file into computer code, typically G-code, for the CNC system to understand and execute the machining process.

This code is transformed into a CNC programme, often using CAM (Computer-Aided Manufacturing) software, allowing control over speed, feed rate and coordination.

Step 3: Setting up the machine

Before starting the machining process, the CNC machine undergoes meticulous set up. This includes securing the workpiece, selecting and installing the appropriate tools and loading the CNC programme.

Subsequently, the operator conducts a trial run to verify there are no errors in the coding.

4. Machining the part

The CNC machine follows the programmed instructions to control the cutting tools, which move along various axes to shape the workpiece. This process is highly precise and can involve multiple tools and operations like drilling, milling and turning.

The CNC machining starts with a block of material, called a blank, and uses fast-moving cutters to quickly carve away material and create the finished part. It carries out the dimensional tasks as specified, much like a robot.

Top 6 advantages of CNC machining


CNC machines operate with extreme accuracy, capable of producing parts with tight tolerances. Consistency Once programmed, CNC machines can produce numerous parts with exact uniformity. The process allows for consistency that would be difficult, if not impossible, to replicate manually.


Changing the production from one part to another is relatively simple, allowing for efficient small-batch production runs or large-scale production.


CNC machining can produce parts quickly, significantly reducing production times compared to traditional methods, for ultimate productivity.


The production of parts via pre-programmed software is mostly automated, requiring minimal intervention from users.

Suitable for a wide range of sectors

Essentially, there are no limits to what you can achieve with CNC machining.

At GW Martin, we are proud to have extensive industry experience working across multiple sectors, including:

  • Defence
  • Aerospace
  • Automotive
  • Medical
  • Commercial

Design for Manufacturing (DFM) is a critical part of the product development cycle and something we’ve focused on growing our expertise in here at GW Martin.

In this article, we explore why DFM is such an important part of the process, including its impact on everything from costs to quality.

What is Design for Manufacturing (DFM)?

Put simply, Design for Manufacturing is the process of designing parts, components and products for ease of manufacturing. The end goal is to make a better product at a lower cost.

Some of the general principles of DFM include:

  • Simplifying the design of parts for quick and efficient assembly
  • Reducing the number of parts required
  • Standardising materials and components
  • Minimising the manufacturing operations required during assembly

At GW Martin, we have the in-house capability to take your design drawings and ensure they represent the most cost-effective and viable solution to manufacturing your component. We always work closely with our customers to reduce costs and achieve outstanding results.

Factors considered during DFM

Several factors are taken into consideration during DFM to ensure a high quality end product. These include:

  • Process: Optimising the product and production line to ensure a strong product
  • Design: Simplifying designs to help cut inventory and waste, saving businesses time and money
  • Materials: Carefully selecting materials, considering properties such as heat resistance, flammability, mechanical strength or moisture resistance
  • Sustainability: Addressing eco-conscious concerns by exploring the use of eco-friendly materials and reducing waste
  • Compliance: Ensuring correct manufacturing processes comply with industry standards for safety and quality

Benefits of DFM

Enhancing product quality

DFM is crucial for quality control and improving the quality of the product. The DFM process ensures that any changes, especially those aimed at lowering component costs, do not compromise product quality.

Increase efficiency

As part of streamlining product processes, minimising assembly steps and preventing line shutdowns in DFM, businesses are able to increase efficiency, ultimately leading to reduced costs over time.


Using standard components instead of custom ones, reduces the cost of producing bespoke parts while maintaining quality.

Reduce costs

DFM goes a long way to help reduce costs, from making cost efficiencies in material selection, reducing inventory and waste, to minimising production costs and simplifying designs.

An estimated 70% of product manufacturing costs are derived from design-based decisions, such as materials and manufacturing methods. The remaining 30% comes down to production decisions, like process planning and tool selection. By optimising these areas, you can significantly reduce your costs.

Quick to market

Streamlining designs and processes during DFM means you can reduce time to market and gain a competitive edge. Simplifying designs can be an easy way to cut extensive inventories, which will also save time and money.


Considering DFM from the beginning of the product development cycle reduces redesign work and improves product quality. By ‘challenging’ the initial designs, you’re able to resolve any potential issues that can come up while scaling from prototype to production.


Businesses and consumers are becoming much more eco-conscious and many are choosing their suppliers based on their commitment to sustainability. We can help clients to look at sustainable materials, as well as reduce raw material usage, waste and energy.

As part of our commitment to reducing our own carbon footprint, our environmental performance is controlled through an Integrated Management System, which is certified to ISO 14001:2015. We have also invested in solar power generation and installed energy efficient LED lighting, and continue to strive to reduce waste. Currently, over 90% of our waste is recycled.

Celebrating 50 Years at Bishopstoke Road

On a sunny morning in Eastleigh, G W Martin and Co Ltd celebrated the 50th anniversary of the opening of their factory. George William Martin started the business in 1959 in buildings once occupied by Fair Oak Dairy on Southampton Road. After strong growth he built his own facility on Bishopstoke Road which was opened on 22nd September 1967 by Sir David Price MP.   Today the team were joined by Mims Davies MP to celebrate the 50th Anniversary.

Mims Davies MP said:

“I am delighted to congratulate G W Martin and Co and join them on their 50 year anniversary at their Bishopstoke Road premises.  It is great to see British manufacturing thriving in the heart of Eastleigh.  I have been impressed to meet such a loyal and experienced team of people from the local community working towards that success.  

With some of the team who started as apprentices in the early days of the factory approaching retirement, their commitment to training young people and bringing new skills into the industry is refreshing.  Apprentices really matter both now and then with 6,000 new ones commencing since 2010 in the Eastleigh constituency.

Having visited the factory a few years ago it is clear that their recent investments in their facility are having a real impact. I wish all at the firm every success for the next 50 years.”
