When a client brings us a project, they don’t just bring a blueprint. They bring a challenge: a complex geometry, a difficult material, a demanding tolerance, or a tight deadline. At Grupo IAM we have been turning those challenges into real parts for more than four decades. In this article, we explain our precision machining process from the moment we receive the assignment until the part leaves our facilities in Bergara ready for use.
1. Receiving the Blueprint and Technical Analysis
It all starts with the client’s blueprint or sample. Our technical team analyzes the geometry, material, required tolerances, and necessary surface finish. In this phase, we decide which technology or combination of technologies is most suitable: Wire EDM, Die-sinking EDM, Waterjet Cutting, Laser Cutting, Micro Cutting, or a combination of several.
In some cases, such as in reverse engineering projects, there is no blueprint available. The IAM team can start from a physical sample and generate the necessary technical documentation through 3D measurement.
2. Material Selection and Preparation
If the material is provided by the client, we verify that it meets the blueprint specifications. If we supply it, we select the appropriate material and prepare it for the process: cutting to size, preliminary roughing if necessary, or heat treatment if the part requires a specific state before precision machining.
3. Precision Machining: EDM and/or Waterjet
Depending on the part type, we work with:
| Technology | Main applications and capabilities |
|---|---|
| Laser Cutting | Formats up to 3000 x 1500 x 20 mm. Maximum speed and precision on metal sheets and profiles. |
| Wire EDM | Complex external and internal profiles, dies, punches, and parts with extreme tolerances down to ±0.002 mm. |
| Die-sinking EDM | Cavities, textures, and internal geometries impossible to mill, especially in molds and dies. |
| Waterjet Cutting | Sheets, non-conductive materials, large thicknesses, or heat-sensitive parts. |
| Micro Waterjet Cutting | Small parts requiring tight tolerances without a heat-affected zone (HAZ). |
4. Dimensional Control and Verification
Once precision machining is complete, each part goes through our quality department. We use a DEA 3D coordinate measuring machine to verify all critical dimensions and confirm that the part meets the blueprint specifications. This step is fundamental: at IAM, we never deliver a part without verifying it is correct.
5. Delivery
The part leaves our facilities with all necessary documentation: the measurement report if required, the delivery note, and any certificate the client has requested. We work with tight deadlines and direct communication with the client throughout the entire process.
If you have a precision machining project, let us know. We analyze your case with no obligation and provide a technical solution and a quote as quickly as possible.
