We are GWM

 

Grainger & Worrall Machining (GWM) is a wholly owned group company. It not only provides an integrated service for in house castings but is also available to third parties as a specialist machine shop for machined only parts (from casting or billet).

GWM uses High-Spec CNC machining centres (3-axis to 5-axis) with up to 24 station Flexible Manufacturing System (FMS) pallet systems. Everything is specified to use the best available - from Coordinate Measurement Machines, CNC programming software and tooling right down to the latest in coolant technology and electronic part-level marking and traceability.

The facility is used to machining, measuring and finishing a wide range of high-complexity machined parts, including Engine Blocks, Cylinder Heads, Battery Trays, Electric Drive Units, Structural Parts, Gearbox Housings and wide variety of specialist components.

The 3,000 m2 facility is fully air conditioned and has its own Metrology Lab kitted out with the latest CMMs (and CMM Programming Software), Bespoke 2D Barcode Laser Marking and Optical Inspection Equipment. There is also an in-house Tool Room for quick turn round of fixtures for prototypes.

GWM has become known as one of the most highly spec'd, built and maintained machining facilities in the market. You have to see it to fully appreciate it, so please contact us to book a tour, or book a free project review to have our experts go over your machining project with you.

Cylinder Heads and Blocks Machining

CNC machining heads & blocks for automotive supply and prototypes

MISSION-CRITICAL CYLINDER HEAD & ENGINE BLOCK MACHINING WITH COMPRESSED LEAD TIMES

At Grainger & Worrall Machining, we know how mission-critical high standards, reliability and compressed lead times are to you. Our innovative new approach to short lead time New Product Introduction (NPI) means we can guarantee precision, quality and lead time reduction with every project.

 

MACHINING HIGH FEATURE CONTENT CYLINDER HEADS AND ENGINE BLOCKS: A NEW APPROACH

Our new approach to machining high feature content Cylinder Heads and Engine Blocks overcomes the challenges often found in the small batch and prototype environment that’s often associated with traditional Horizontal methods. This innovative New Product Introduction (NPI) capability allows us to:

  • Compress lead times for prototype production. We’ve equipped our Machine Shop with high spec vertical and 5 axis machines alongside our production machining cell. This means we can break down individual operations and spread them over a range of machines, proving a number of operations simultaneously to reduce lead times.

  • Apply this technology to a variety of components. Our new approach to NPI lends itself to machining a number and variety of complex prismatic components.

  • Tightly control production throughout. You need reliability. Our computerised co-ordinate measuring programmes ensure the end product meets carefully pre-defined specifications, every single time.

Procurement Outsourcing

making your life easier with complete solutions and peace of mind.

Put simply, we want to make your life easier. That’s why we offer comprehensive procurement outsourcing in support of our high quality castings. This second tier supplier management and quality-guaranteed machining service is designed to allow you to focus on the overall product, as well as reduce product development support costs.

PROCUREMENT OUTSOURCING:

INVALUABLE SUPPORT FOR YOUR ENTIRE PROJECT

Whether you have an integrated procurement team or not, we can manage subcontracted service providers for you, using our valuable experience to support you across your whole project. Our machining support services include:

  • SQA

  • Contract management

  • Cost reduction

  • Progress chasing

This is invaluable, as the project team is developed by the customer to support the actual production procurement activities in the longer term of the project.

Quality Assured, Precision Machining

world-class CNC machining for your project

When it comes to machining, you need the entire production process to be quality-assured, precise and reliable. This integrity is why we’ve invested heavily in our processes to ensure we have robust, accurate quality checks in place. No matter at what point in the process, you’ll have complete confidence in the outcome.
Your high standards are our high standards.

WANT ACCURATE INSPECTION CHECKS THROUGHOUT THE MACHINING PROCESS?

That’s no problem. To support our aggressive approach to New Product Introduction (NPI) we’ve invested heavily into the latest CMM hardware & software.

  • We use the latest PC dmis software to guarantee we can quickly and accurately inspect any feature which we’ve machined.

  • Our multiple, DEA Global 12:22:10 CMM machine means producing inspection reports in an internationally recognised format is easy, referencing back to your original drawing.

If you need in-process critical feature checks, SPC or capability studies, they’re no problem either. All of our CMM machines are capable of collecting and processing the data you need, whenever you need it.

And if required, many machined features can be checked before they even leave the machine table with; 

  • the use of air gauging

  • hard gauging

  • or more specific hand held inspection devices.
