Engineering Support

GTR Manufacturing’s experienced engineering department can provide concepts, product enhancements, and reverse engineering. We will work with your team to deliver your parts at competitive costs.

Our sales, management, and engineering teams have experience in a wide range of industries and understand their changing needs. We work in close partnership with our clients in developing and refining product designs and production process planning to simplify manufacturing and create cost savings for your end product.

We have the capability to import and unfold your 3D models ( .dwg, .step, .iges, .sldasm, .ldprt, .dxf) built in Solid Works, Pro/E, and other modeling software. The model is unfolded and downloaded directly into the CAM process, reducing errors and assisting in short lead times for your sheet metal parts.

GTR-Manufacturing-JIT-Kanban-Inventory-Image

JIT / KANBAN

By using the Just-In-Time (JIT) inventory strategy, GTR Manufacturing schedules production to meet your ordering needs. We reduce costs by carrying less idle inventory, resulting in a quality product that is delivered on time at a lower price.

We pair JIT with the Kanban technique to manage our highly-efficient development process. We establish minimum and maximum quantities, fulfilling customer needs on a pull system. This method empowers us to reduce inventory for customers and suppliers and uses lean production practices. In addition, we have full insight into your pipeline through an online portal, ensuring it’s always full.

Are GTR’s CNC Milling and Turning Services Right For Your Next Project?

  • Is your business in need of custom metal work that adheres to specific requirements?
  • Have other manufacturers looked at your blueprints and ruled that your systems are “too difficult” or complicated to create?
  • Are you looking for a straightforward job but are surprised at how long the lead times are?

We are proud to simplify the machining processes by offering CNC milling and turning as part of our one-stop-shop capabilities to speed up project timelines and lower the risk associated with relying on external supply chains. With complete oversight and control over the entire production process—from prototyping to shipping—GTR ensures uncompromised, on-time quality and delivery.

FAQ

What is the difference between CNC milling and CNC turning?

L
K

CNC milling uses rotating cutting tools to remove material from a stationary workpiece, making it ideal for flat surfaces, complex geometries, and intricate features. CNC turning, on the other hand, rotates the workpiece while a cutting tool shapes it—making it best suited for cylindrical or round components.

What types of parts can you produce with CNC milling and turning?

L
K
GTR manufactures a wide range of custom precision parts, including:

  • Complex multi-axis components
  • Cylindrical and rotational parts
  • Prototypes and production parts
  • Tight-tolerance, high-precision components

Our equipment supports both simple and highly complex geometries across industries. Submit your part to see if we can manufacture.

Do you support both prototyping and production runs?

L
K

Yes. We handle everything from single prototypes to full-scale production, allowing customers to scale seamlessly from design validation to manufacturing.

How do I know which process is right for my part?

L
K

Our team evaluates your part design, material, tolerances, and end-use requirements to determine the best manufacturing approach. In many cases, a combination of CNC milling and turning may be used to achieve optimal results. If you’re unsure, we’re happy to review your design and provide recommendations.

What is your typical turnaround time?

L
K

Lead times vary by part complexity and volume, but we work closely with our clients to meet their project deadlines
