CNC machining at TOS: precision and quality

CNC machining (Computer Numerical Control) is a modern machining technique that removes metal or plastic with extreme precision to create the desired shape. Thanks to our advanced CNC machines, we can achieve complex shapes, tight tolerances, and fine details with a high degree of reproducibility. This makes CNC machining ideal for customers who demand high dimensional accuracy and reliability.

Depending on the product requirements, we utilize various techniques: CNC milling, turning, drilling, and tapping. This makes CNC machining suitable for prototypes, small production runs, and large-scale series production. Our strength lies in the flexibility to quickly switch between one-piece customization and efficient series production, always with the same high quality.

At TOS, we ensure the right balance between material selection, tolerances, and production efficiency. Our engineers advise clients on design according to Design for Manufacturing (DFM) and guide the entire process from prototype to series production. In addition to CNC machining, we offer additional surface treatments such as anodizing, powder coating, and galvanizing. This ensures that components not only perform optimally functionally but also have a high-quality and durable appearance.

With our integrated approach—from drawings and engineering to finished product—TOS guarantees quality, speed, and reliability. This means you have a single point of contact for the entire CNC machining process.

How we work

First acquaintance

During this conversation we will briefly explain what we can do for you and answer your questions.

Price research

Based on your product and requirements, we request prices and delivery times from various suppliers.

Quotation and agreement

We will then prepare a clear quote. Prices are quoted based on your terms and conditions.

Prototype and approval

Once you have approved our proposal, we will start making a prototype.

Quality control and delivery

After approval of the prototype, the assignment will begin.

Materials and alloys for CNC machining

CNC machining can be applied to a wide range of materials. Commonly used materials include aluminum alloys (light, strong, and easy to machine), steel and stainless steel (high-strength and wear-resistant), and plastics (light, electrically insulating, and versatile). Copper and brass are also frequently used due to their good conductivity and ease of machining. At TOS, we recommend the right material for each project, tailored to strength, weight, functionality, and surface quality. This ensures you receive components that perfectly match your application.

Advantages and disadvantages of CNC machining

  • Very high accuracy – Suitable for tight tolerances and complex shapes.
  • Flexible in materials – Can be used on metal and plastic.
  • Suitable for small and large series – From prototype to mass production.
  • Material loss – Because it is a machining technique, waste is generated.
  • Costs for complex shapes – Long processing times can increase the price.

CNC machining at TOS: efficient and accurate

In addition, surface treatments are essential for improving both functionality and appearance. Anodizing applies a protective oxide layer that is wear-resistant and provides a high-quality finish. Powder coating offers a wide range of colors and an additional layer of protection against external influences.

At TOS – Technical Outsource Solutions, we manage the entire process: from extrusion and CNC machining to anodizing and powder coating. This means you have a single partner for a complete and high-quality end product, tailored to your needs and specifications.

A CNC machining process always begins with an intake interview. Here, we discuss the application, desired volumes, budget, and delivery times. By carefully analyzing this information, we can offer a suitable solution that is both technically and economically feasible.
Our engineers provide advice based on the Design for Manufacturing principle. We optimize the design for CNC machining by considering tolerances, machining strategies, and material selection. Whether it’s aluminum, steel, or plastic, we ensure that the design can be produced efficiently and cost-effectively.
After the initial consultation and design optimization, the customer receives a transparent quote. This quote clearly details the costs for CNC machining, including any post-processing and surface treatments. We also provide a realistic schedule, so the customer knows exactly when parts will be delivered.
A crucial part of CNC machining is programming the machines. Our specialists develop CNC programs based on the drawings and configure the machines precisely. This guarantees efficient and error-free machining, even with complex geometries.
Before starting series production, we conduct a trial run. During this First Article Inspection (FAI), the first parts are carefully inspected for dimensions and tolerances. Any improvements are implemented immediately, ensuring that the final series, CNC machined, fully meets the specifications.
After the pilot production phase, the design freeze follows. In this phase, feedback is incorporated and the final specifications are established. This provides clarity for both the customer and the manufacturer and forms the basis for stable and reproducible CNC machining production.
During serial production, we manufacture components according to drawings and quality standards. Thanks to modern CNC machinery, we can efficiently produce both small and large series. The result is consistent quality with high precision and short lead times.
After CNC machining, components can be surface-treated. We offer various options, such as anodizing for aluminum, powder coating for protection and appearance, or galvanizing for added durability. This not only gives components their functional value but also a high-quality finish.
All components produced using CNC machining undergo strict quality control. We perform both visual and dimensional inspections and provide certificates and measurement reports upon request. This guarantees that the components meet the required standards and requirements.

Finally, we handle component assembly, customer-specific packaging, and logistics. Thanks to inventory management, customs clearance, and export preparation, we offer customers a complete service. With TOS, you have a single point of contact for the entire CNC machining process – from drawing to finished product.
