A good surface is obtained in the following five steps, respectively.
- Degreasing (pre-washing process)
- Deburring
- Polishing
- Rinse
- Drying
What is a burr?
Burrs are residual parts of height or protruding edge or material that remain on its surface, edges, or product-specific parts after production, which are produced by machines such as presses or CNCs that process metal plates or metal blocks. It is compulsory to be cleaned both for subsequent processes and in order not to disturb during use. All burrs are destroyed by the process called ‘deburring’ and different types of machines.
What are the stages of the deburring process?
The deburring process consists of three stages. For the best results, operations are performed in the following order.
- Degreasing (pre-washing process)
- Deburring process
- Rinsing process
1- Why should degreasing be done?
The degreasing process is the first surface treatment stage and is of great importance for all other stages. Because a strong friction force is required for the most accurate result. Since the friction force occurs on the most oil-free surfaces, products, and abrasive stones should be degreased by pre-washing. Thus, the degreasing process, which is an additional process under normal conditions, was also applied during surface finishing and no extra degreasing process is required. KAYAKOCVIB deburring fluids are of two types and suitable deburring fluid is determined according to the raw material from which the product is produced.
2- Deburring process
Deburring is the second stage of the products produced with various metal raw materials after production. The burrs of the products are cleaned with various chemical content liquids used in combination with vibration or centrifugal machines and abrasive stones (chips, media) produced in plastic or ceramic structures called “deburring stones”. Deburring takes place with the friction effect of abrasive stones and metal parts. As a result of the harmony of abrasive stones and the geometric structure of the product, it is applied equally and equally to all edges, corners, and surfaces of the product. Smooth edges, corners, and a homogeneous surface are obtained, although they differ from the product to the product. KAYAKOCVIB deburring fluids are of two types and suitable deburring fluid is determined according to the raw material from which the product is produced.
3- Why should rinsing be done?
Products that have been removed from burrs and which will go to the next process should be purified from chemicals containing liquids used in degreasing and deburring. Therefore, the last of the surface treatment stages is “rinsing” with water only. If the products are to be polished after deburring, the polishing step is started without the need for rinsing, but rinsing is the most appropriate finishing process for coating or other processes.
