CNC machining of parts in small and medium batches.

We manufacture batches of approximately 5 to 500 parts in metals and engineering plastics. CNC milling and turning in our own workshop, with drawing review, finishing options and delivery planning.

A visual concept inspired by the i-mas machining workshop. The original asymmetric casing for NEXO is machined on a five-axis tilting and rotating table: first, the cavity is machined, then the table is oriented to open the side port, and the piece is checked with a probe. Once finished, the completed casing is removed and a new raw piece is inserted; the machine remains in its position. This is an illustrative process, not a CAM simulation. The animation plays automatically in a loop; drag to rotate the camera in any direction and double-click to return to the original view.

01 / Purpose

A workshop built for your production batches.

Our speciality is CNC machining in small and medium batches. We work with companies that need to manufacture a batch of parts, reorder a part or prepare components for a machine or product.

We review the geometry, material, quantities and drawing dimensions before quoting. The aim is to define a manufacturing process suited to the part’s purpose and batch size.

02 / Services

What do we do in machining?

You can either hire the entire process or a specific service. All of this is carried out by the same team, with the workshop and laboratory located nearby.

01

Custom parts machining

Milling and turning from your model or drawing, using the material and specifications required for the part. Manufacturing is organised for small and medium batches.

02

Small and medium batches

Batches of approximately 5 to 500 units for machines, products and repeat orders. We can review an initial batch and prepare continued production of the same part.

03

Subset assembly

When an order includes several parts, we can include subassembly and inspection. We define which components and operations are included in the supply.

03 / How we work

From 5 to 500 parts, with continuity between orders.

This is our usual production range. We organise programming, workholding and manufacturing for small and medium batches, and retain process information to make repeat orders easier.

If a dimension, finish or geometry makes manufacturing more complex, we review it with you before starting the order. The quote specifies the material, quantity, requirements and agreed lead time.

04 / Process

From drawing to finished parts in four steps

A useful quote starts with a clear specification.

  1. 01

    Define your order

    Prepare the STEP model, a PDF drawing if available, quantity, material, critical dimensions, finish and preferred delivery date.

  2. 02

    We review manufacturability

    We assess the part, operations and drawing requirements. We discuss any points that need clarification with you.

  3. 03

    We agree on the quote and lead time

    We define the scope of supply and delivery before starting the batch.

  4. 04

    We manufacture, inspect and deliver

    We machine the parts and check the agreed requirements. Finishing and assembly are included when specified in the order.

05 / Areas

Machining processes and materials

5-axis milling

DMG CMX 50 centers with EROWA loading robot, handling up to 50 pallets: complex geometries in a single tie-down, and unattended production outside of workshop hours.

Turning

Turning machines with motorized tools, auxiliary attachments, and an automatic bar loading system. The rotating parts emerge from the machine finished.

Metals

We machine metal parts to the alloy and material condition specified in the order. If the grade has not been defined, we review it with you.

Engineering plastics

We manufacture functional components in engineering plastics. We review the material, geometry and application requirements before defining the process.

Finishing

Parts finished to suit your application.

We can include the finishes listed in the Proto&Go catalogue. We confirm compatibility with the material and drawing requirements before quoting.

  • Anodising
  • Blasting
  • Polishing
  • Black oxide
  • Zinc plating
  • Chrome plating
  • Nickel plating
  • Painting

Pigmentation in the catalogue applies to polyurethane parts made using silicone moulds; see Prototyping for that option. It is not a CNC machining finish.

Product design and engineering

If you still need to develop the geometry or define the product, our design and engineering team can support you before manufacturing.

Frequently Asked Questions

Before requesting a CNC machining quote

What batch sizes can be CNC machined?

We specialise in small and medium batches of approximately 5 to 500 parts. Specify the quantity per part and whether repeat orders are expected so we can organise programming, workholding and production. For a single validation part, see the group’s Prototyping service.

Which materials can be machined?

We work with metals and engineering plastics. To quote, we need the material grade or the part’s application requirements. The alloy, supply condition and finish are reviewed alongside the geometry and drawing dimensions.

Which tolerances should be specified on the drawing?

Specify the general tolerances and dimensions critical to assembly or operation. We work with standard machining tolerances and review specific requirements before accepting an order. Feasibility depends on geometry, material, size and finish; one tolerance figure does not apply to every part.

What information do I need to request a quote?

A STEP 3D model and, if available, a PDF drawing showing critical dimensions. Include quantity per part, material, finish and preferred delivery date. Email the files or share a link in the form; we clarify any missing specification before manufacturing.

Can machined parts be supplied with finishing and assembly?

Yes. We can include material-compatible finishes and subassembly when required. Specify functional surfaces, fits and the desired appearance so finishing can be considered when defining manufacturing and inspection.

Where is the i-mas machining workshop?

The workshop is in Montcada i Reixac, Barcelona. Submit your enquiry by email or through the form on this page. We review the documentation and agree on supply and delivery arrangements with your team.
