We accept the main technical and drawing formats: STEP, IGES, DXF, DWG, PDF and other industry-standard formats. Both 3D files and 2D drawings can be sent. In case of doubts about the format, the file can still be sent: it will be checked and confirmation will be provided on whether it is suitable for the requested machining.

For 3D models, STEP is recommended as the preferred format because it is stable, accurate, and compatible with most CAD software. IGES and other neutral formats are also accepted, but STEP reduces the risk of import errors. If possible, models should be exported in STEP with clearly defined units of measurement (mm or inch).

For 2D drawings, DXF or DWG is recommended, in a recent but non-experimental version. PDF files are also accepted for consultation or approval only. In DXF/DWG files, a single unit system, clear layers, and readable dimensions are required. PDF is useful as a visual reference, but for production an editable CAD file is always preferred.

Yes, to work safely and accurately, the following are required: closed, error-free geometries, no superfluous elements (unnecessary text, unused blocks), correct scale and defined units of measurement, and readable dimensions and tolerances where needed. For 3D files, avoid overlapping or open surfaces. If anything in the file is unclear, contact will be made before proceeding.

Files can be sent via the contact form by attaching them directly to the request, or by e‑mail to the address indicated in the contacts section. For large files, a transfer service is recommended (e.g. WeTransfer or a cloud link). The project reference and contact details should always be included in the message so that a prompt reply can be provided.

If the file contains errors, lacks information, or the format is not suitable, production will not proceed without prior notice. The issue will be clearly indicated and a solution will be proposed: correction of the file, a request for a new submission or, if possible, adjustment by the team upon agreement. This ensures a reliable result that meets expectations.

In the absence of specific indications on the technical drawing, general dimensional tolerances are applied based on the main reference standards (for example ISO 2768 for generic machining operations). In practice, for linear dimensions, tolerance ranges are used that vary according to the nominal length: for small dimensions (e.g. up to 10 mm) the tolerance is tighter, while for greater lengths the permissible range increases slightly. This approach ensures a good compromise between accuracy, production costs and delivery times, while still maintaining full functionality of the part in most standard applications.

Yes, it is possible to request special tolerances, both tighter and asymmetrical, as long as they are clearly indicated on the technical drawing or agreed upon during the quotation phase. For example, it is possible to work with tolerances in the order of ±0.01 mm on certain critical dimensions, if the material and technology allow it. In these cases, the technical feasibility is evaluated together with the customer, as well as any need for additional machining (grinding, lapping, 100% inspection) and the impact on costs and lead times. The tighter the tolerance, the greater the machining and inspection time that will generally be required.

Tolerances can be indicated in two main ways: as general tolerances in the title block (for example, a table that defines tolerances according to the measurement range) and as specific tolerances next to individual critical dimensions. For the most important dimensions, it is recommended to use clear notation, for example 25.00 ±0.05 mm or a limit range of 24.95–25.05 mm. When using ISO tolerance systems (e.g. H7, g6), it is also useful to specify the relevant standard. The clearer and more complete the drawing is, the lower the risk of misinterpretation and non-conformities.

The material has a direct impact on the achievable accuracy and on dimensional stability over time. Very hard or tough metals may require specific tools and cutting parameters, with possible minimal dimensional variations due to tool wear. Soft or plastic materials (such as some light alloys or polymers) can deform during clamping or cooling, making it more difficult to maintain very tight tolerances. In addition, the coefficient of thermal expansion affects dimensions: a long aluminum part, for example, can vary significantly with temperature. For this reason, in the case of critical tolerances, the type of material and the expected operating conditions are always evaluated.

Each production technology has a typical precision range. CNC milling and turning operations generally allow tighter tolerances than laser cutting, plasma cutting, or molding. For example, a hole made with CNC drilling and reaming can achieve hundredth-of-a-millimeter tolerances, while a hole obtained by laser cutting will have wider tolerances and less controlled edges. 3D printing processes also have specific limits, often with wider tolerances than traditional machining. When a drawing is received with very tight tolerances, the chosen technology is checked for compatibility and, if necessary, alternative solutions are proposed.

Yes, surface treatments and finishes can significantly affect the final dimensions of the part. Coatings such as galvanizing, nickel plating or painting add a thickness that, if not considered during the design phase, can cause holes, fits or reference surfaces to go out of tolerance. For example, powder coating can add a few tenths of a millimetre, while electroless nickel plating may require controlled overplating. Heat treatments can also cause deformations or dimensional changes. For critical dimensions, it is important to specify whether the tolerance refers to the part before or after treatment, so that the machining cycle can be set correctly.

A typical example is the hole–shaft fit for a sliding assembly. Suppose there is a nominal 10 mm shaft and a corresponding hole. To ensure smooth sliding, the shaft could be defined as 10.00 −0.02/−0.04 mm and the hole as 10.00 +0.02/+0.04 mm. In this way, the shaft will always be slightly smaller than the hole, avoiding interference. If a more precise fit or an almost clearance-free fit is required, tighter tolerances or ISO systems (e.g. H7 hole and g6 shaft) can be used. When placing an order, it is useful to clearly specify the desired type of fit (sliding, transition, interference) in order to choose the most suitable tolerance range.

Production times are estimated by evaluating four main factors: part complexity, required quantity, type of material, and current workload. The technical drawing or product description is analyzed, the necessary machining operations are verified, and this data is cross-checked with the availability of machines and personnel. This makes it possible to provide a realistic estimate, indicating both the expected average time and any variables that could affect delivery.

The greater the complexity of the part, the more time is required for programming, machine setup, and quality checks. Complex geometries, tight tolerances, or special finishes require additional steps and more accurate inspections. For this reason, given the same quantity, a simple part can be produced in a few days, while a very complex one may require longer lead times. During the quotation phase, it is always indicated if complexity has a significant impact on delivery times.

For small batches, lead times are often mainly linked to the preparation phase (programming, setup, material procurement). As volumes increase, these initial costs are spread over more parts, but the actual production time grows. In practice, for medium to high quantities the total time increases, but the time per single part tends to decrease. During the quotation phase, a separate estimate is always provided for different quantity ranges, so it is possible to evaluate the best balance between lead times and unit cost.

In general, a strict minimum quantity is not required, but for certain products or processes a minimum batch size is recommended to keep the price sustainable. This is because start-up costs are similar whether producing a few pieces or larger batches. If only a very small number of pieces is needed, the impact on costs and lead times will be clearly explained, and, where possible, alternative solutions or batch combinations will be suggested to make the order more cost-effective.

Yes, in many cases a rapid production service can be offered, with priority over standard scheduling. Feasibility depends on the type of part, the material available, and the workload of the production lines. The express service usually involves an additional charge, which is communicated in advance together with a dedicated delivery date. The goal is to be clear from the outset, so it is possible to decide whether to choose the standard or urgent option based on specific needs.

For recurring supplies or scheduled volumes over time, planning can be optimized, reducing average delivery times. In these cases, it is possible to consider safety stocks, scheduled calendar-based production, or framework agreements. This makes it possible to reserve dedicated production capacity and respond more quickly to requests. During the initial phase, a realistic plan is defined together, with clear delivery windows, to avoid sudden emergencies and manage expectations in the best possible way.

For shipments, only national and international express couriers with proven reliability are used, selected for their punctuality and care in handling parcels. Every order is packed with protective materials suitable for its contents, in order to minimize the risk of damage during transport. Before shipping, a final quality check is carried out and a tracking code is generated, which is sent via e‑mail together with the order summary. This makes it possible to follow every stage of the parcel’s journey in real time, from the warehouse to delivery.

Average delivery times vary depending on the destination and the service selected, but in general domestic shipments take 2–4 business days, while shipments to major European countries take 4–7 business days. For some more remote areas, a few additional days may be required. In any case, a constantly updated tracking link is always provided, available 24/7, allowing verification of the shipment status, any holds, and the estimated delivery date. The support team monitors the most sensitive shipments and intervenes promptly in the event of any issues.

We ship regularly throughout Italy, including the islands, and to most countries within the European Union. On request, shipments can be arranged to other international destinations, assessing on a case-by-case basis the timing, costs, and safest transport methods. For deliveries with particularly tight deadlines, urgent shipping options are available via dedicated express couriers, with indicative transit times of 24–48 hours on the main national routes. During the quotation phase, all available solutions are always outlined, with estimated costs and delivery times, to allow for a conscious and worry-free choice.
