As Doğa Makina, we provide CNC machining services in accordance with high precision and quality standards. We use various materials in our production process and we offer the most suitable solutions to our customers by paying attention to the hardness values obtained after heat treatment of each material. We produce the desired parts in accordance with all values such as materials and hardness coating specified in the technical drawings. Here are the materials we use most frequently in CNC machining and the properties of these materials:
Carburising Materials
Carburising is applied for surface hardening of low carbon steels. With this process, the surface of the steel remains hard and the interior remains softer, which increases the wear resistance of the material. Carburising materials include:
Nitration Materials
Nitriding is used to increase the surface hardness of materials. This process improves the wear and fatigue resistance of materials. Nitriding materials include:
Breeding Steels
Reclaimed steels are used in applications requiring high strength and toughness. The reclamation process improves the mechanical properties of the material. Among the breeding steels:
Stainless Steels
Stainless steels are materials with high corrosion resistance and are often used in corrosive environments. Stainless steels include:
Aluminium and Aluminium Alloys
Aluminium and its alloys are known for their light weight and high strength properties. These materials are often used in the automotive and aerospace industries. Aluminium alloys include:
Table of Materials and Hardness Values Specified in Technical Drawing
As Doğa Makina, we produce by taking into account all the materials and values such as hardness coating specified in the technical drawings. We ensure that every part we process on our CNC machines complies with customer requirements and technical specifications. With our quality control processes, we ensure that all products are manufactured in accordance with the standards.
