Products and services

Manufacturing, reconditioning and dimensional checking of industrial mechanical components, always from a technical drawing or a physical sample.

Lines of work

Four areas of activity

Each area can be contracted on its own or combined — for example, manufacturing a replacement component from a drawing or sample and delivering it with a dimensional check.

Industrial gears

Industrial gears

Spur and helical gears, straight bevel gears, sprockets, timing-belt pulleys, splines, racks and screws — including a gear tooth milling service.

Worm wheels and worm shafts

Worm wheels and worm shafts

Bronze worm wheels and single or multi-start worm shafts with ground finish, full re-cutting of teeth and worm manufacturing to the required centre distance.

Industrial gearboxes

Industrial gearboxes

Overhaul, reconditioning and upgrading of gearboxes, with analysis and manufacturing of replacement components from drawing or sample.

Custom machining

Custom machining

Precision milling and machining of special parts, gear rims, replacement of discontinued items and industrial maintenance demands.

Capacity assessed case by case according to drawing, material, dimensions and application.

Workflow

How we handle your request

  1. 01

    Send the drawing, sample or requirement

    You send the technical drawing, photos, the reference part, or simply describe the problem to be solved — including urgent machine-stoppage cases.

  2. 02

    Technical analysis

    We assess the geometry, the type of component, the application and what is needed to reproduce or recondition it, including the condition of the part such as hardness and distortion.

  3. 03

    Material, process, lead time and scope

    Together we define the material, the manufacturing process, the scope of work and the lead time achievable.

  4. 04

    Quotation

    You receive the commercial proposal with the agreed technical scope.

  5. 05

    Manufacturing or reconditioning

    The part is machined, manufactured or reconditioned according to the approved scope.

  6. 06

    Dimensional check, release and collection

    We carry out the dimensional verification of the component, confirm release for collection and issue the return invoice.

The process may vary according to the complexity of the project.
