Successfully scaling series turning work requires more than just available machine capacity. It requires control over product information, manufacturability, production location, material, measurement methods, and delivery. It is precisely in this synergy that Roosen makes the difference.
Roosen manages the entire route from drawing to structural delivery. We bring product and process knowledge together, select the production environment in the Netherlands or India for each component, and produce every series according to the same agreements. This creates a reproducible production approach from the very first sample that can grow along with your demand.
Product information, manufacturability, processing, and measurement methods are aligned before the start of the series. This ensures the series starts on a foundation that is reproducible.
Automated machining in the Netherlands and series capacity in India together form one machining organization with a single point of responsibility towards the customer.
Roosen organizes the purchase of material and includes subsequent steps in the same production route. As a result, material flow, production, and delivery are seamlessly aligned.
Critical dimensions are checked in a conditioned measuring room and recorded in the agreed quality documentation.
Through a New Product Introduction (NPI), we translate your component into a reproducible production approach. We check the product information, record the processing sequence and measurement method, and validate the sample before the series is released. This ensures series production starts on a repeatable basis.
Roosen identifies dependencies in capacity, material availability, and delivery continuity in advance. With our own machining capacity in the Netherlands and India, we set up production so it can grow in a controlled manner, in the production environment that best suits the tolerance and predictability of the component.
We collect, check, and update drawings, specifications, and available practical knowledge before production starts. We identify missing or contradictory information and test both the component and the process with a sample. This makes the knowledge transferable to a stable production process.
We align the production environment, processing route, and chain steps for each component. Repetitive, predictable series can be placed with Roosen India, offering an attractive cost structure and the same quality requirements. This creates a balance between quality, delivery reliability, capacity, and cost price that holds up over the entire lifecycle.

More volume requires more than just more machine hours. The real question is whether the component, process, and chain are set up so that every subsequent part falls within the same tolerances and every delivery follows the agreed rhythm. Problems that become visible during growth often originated earlier: a drawing package that is no longer up to date, practical knowledge left behind with a previous supplier, or a production location that does not match the required precision.
Roosen helps
We look beyond the first delivery from the very beginning. For each component, we determine which production environment fits the tolerance, complexity, and predictability, and we align capacity, material availability, and delivery rhythm with your forecast. Where regional capacity is scarce, the combination of the Netherlands and India provides the space to grow in a controlled manner.
What this delivers for you
A stable production approach that can grow with your demand, with predictable quality, manageable risks, and delivery times you can plan around.
In series turning, it's all about repeatability. That's why we don't just set up what needs to be turned, but also how it is processed, measured, and released. This makes quality reproducible and scaling manageable.
Processed according to recorded specifications
Every series is produced according to the agreed product information, processing sequence, and quality criteria, regardless of the production location.
Automation as the basis for stability
In the Netherlands, lathes and turn-mill combinations are loaded by robots and cobots wherever possible. This allows for unmanned production to continue under consistent process conditions, even outside of working hours.
Completely processed in a single production run
Components requiring both turning and milling operations are completely processed on turn-mill combinations in both countries. This limits the number of transfers between operations.
Inspected before delivery
Every series starts only after the sample has been released. If you use your own acceptance procedure, we incorporate it into the production process.
Roosen has its own machining capacity in the Netherlands and India. This allows us to choose the environment that adds the most value for each component. Turning work with tolerances tighter than 0.05 millimeters, more specialized operations, and components needed on short notice remain in the automated Dutch production. Repetitive, predictable series are placed with Roosen India, where three-shift production, a dedicated quality organization, and an attractive cost structure come together.
Roosen India has been an integral part of the group since 2006 and is the unit with the highest delivery reliability. Therefore, the production distribution does not change your point of contact, agreements, or final responsibility, which remain within the Dutch organization.
When material purchasing, machining, surface treatment, and logistics are handled by different parties, the management remains with you. This takes time and makes transfer and scaling vulnerable.
Roosen takes responsibility for that synergy. We check product information, organize material purchasing, handle work preparation and programming, produce and measure the components, and organize packaging and delivery. Where surface treatment is required, we include it in the same route via an external partner.
This means you are not just choosing a separate turning supplier, but a production partner who makes the whole process manageable and looks ahead with you.
We translate your drawing into a repeatable operation, including programming, and record what is needed for production, measurement, and scaling.
Roosen organizes the purchase and availability of material, aligned with the production planning. This keeps the production flow manageable.
We produce turned and turn-milled parts in materials including steel, stainless steel, aluminum, brass, and plastic, in the production environment that fits the component.
Critical dimensions are measured with 3D measuring equipment. Measurement reports are part of the quality documentation we agree upon with you.
Where your component requires surface treatment, it is included in the production route via an external partner.
After release, we pack and deliver your components as agreed.
Within the group, a turned part can be further milled, assembled into a mechatronic assembly, or cleaned and packaged under cleanroom conditions.
A strong collaboration starts with clear responsibilities. You remain the owner of the component, the design, and the specifications. Together, we determine which parts of industrialization, chain management, and execution Roosen will take over.
One partner from drawing to delivery
Knowledge about your component remains secured within a single approach, even when production is divided across two countries.
Management of manageable scaling
We set up processing, capacity, and material flow with the next growth phase in mind.
Broad manufacturing expertise within the group
Turning work is connected with milling, mechatronics, cleanroom activities, and international production capacity.
Personal guidance
A dedicated Dutch account manager who knows your components, planning, and the development of your demand.
The determining factor is whether the demand is serial and repetitive, and whether the component can be made within a fixed production approach. Typically, this involves 100 to 10,000 units per year. Since the processing time per component varies from one minute to several hours, the quantity alone does not tell the whole story. Single items and one-off orders fall outside the order profile.
The determining factors are tolerance, complexity, and predictability, not the series size. Repetitive turning work with tolerances from 0.05 millimeters aligns well with the capabilities of Roosen India. Tighter tolerances, more specialized operations, and components needed on short notice are produced in the Netherlands. This choice is made in advance for each component.
This depends on the production location. For Roosen India, a lead time of approximately 120 days applies for the first delivery, followed by monthly deliveries. Turning work that is needed faster or for which demand is difficult to predict is scheduled in the Netherlands.
In principle, all common materials, including steel, stainless steel, aluminum, brass, and various plastics. Special materials fall outside the standard offering. We assess whether a material is suitable on a per-product basis.
Roosen India is certified according to ISO 9001, 14001, and 45001. The Dutch organization holds ISO 14001 and ISO 45001.
The determining factor is how predictable the extra demand is. An increase known in advance is easiest to schedule. Unexpected increases can also usually be accommodated, whereby we determine which part of the extra production best fits in the Netherlands or in India.
The determining factor is how complete the product information and available practical knowledge are. We start by bringing these together and checking them. Subsequently, we validate the production approach via a sample before the series is released.
That depends on the next step your component goes through. Within the group, turned parts can be milled, mounted in mechatronic assemblies, or cleaned and packaged under cleanroom conditions. This allows the production from component to assembly to be organized within a single coordinated chain.
