- CNC machining
CNC means controlling production machines using computers, with programming languages that comply with the EIA-274-D standard (also known as G-code).
We primarily use CNC to produce parts in plastic, but it is also possible to produce parts in metal, wood , and other materials. CNC-controlled machines achieve better accuracy (tolerances) on the parts and can produce faster than manually controlled machines.
CNC machines can work both two-dimensionally and three-dimensionally using their coordinate axes. Typically, the machines have three axes (X, Y, and Z), but the machine we use daily is a 4-axis CNC-RETU machine.
A typical 3-axis CNC mill creates parts by moving the spindle up and down, side to side, and back and forth. The cutting tool, attached to the spindle, cuts pieces away from the workpiece as the spindle moves along the three axes. With 3-axis machining, the cutting tool’s angle remains constant, pointing downward or sideways, making it harder to cut away material in hard-to-reach parts of the workpiece.
Our 4-axis machine, capable of changing the cutting tool's angle, is therefore better suited for handling milling with higher precision and accuracy, eliminating the need for multiple setups for one part. Machines with 4 axes increase productivity by reducing the setup and handling process. Our CNC machine plays a significant role in streamlining our production line.
We also have portable CNC Smartbench machines that can be taken "on-site" to perform tasks where appropriate.
Recycling:
CNC work creates some chip and scrap waste from the plastic sheets used for milling. This waste is collected and fed into a shredder, which grinds the material into small pieces. The shredded waste is collected in bags and sent for recycling. Through our partner, Arges AS, we have an agreement where they produce pellets from our waste, which can then be used to produce pipes and/or sheets that the company purchases. This material can then be used to make suitable products again. The same process can be used in our return program when purchasing products.
Advantages of CNC Machining Services:
- High Precision and Accuracy:CNC machines can produce components with very high accuracy and repeatability, providing consistent results every time.
- Increased Productivity and Efficiency: CNC machines can run continuously without the need for breaks, except for maintenance and tool changes. They can also work faster than manual machines, increasing production speed and reducing production time.
- Reduced Risk of Human Error: Automation in CNC machining minimizes the risk of human errors. The software controlling the CNC machine ensures that each component is produced as accurately as specified.
- Reduced Environmental Impact: Waste from CNC machining can be recycled into new products. Precise machining also reduces scrap and the need for rework, saving time, money, and the environment.
Our partner, AM North AS, has a 5-axis CNC machine exclusively for the production of metal products.
