These operations can be done through CNC turning: TURNING MILLING HOLE MACHINING THREADING KNURLING FORMING SCREW HEADS MARKING & ENGRAVING TURNING WHAT IS TURNING? By turning, the material can be shaped exactly to the desired cylindrical shape. A rough insert reshapes the material, while the fine cutting tool gives a nicer surface and measurements of thousandths of a millimeter. ​ IT IS POSSIBLE TO TURN: HORIZONTAL VERTICAL DIAGONAL ROUND SLOT LEARN MORE ABOUT TURNING MILLING WHAT IS MILLING? Milling like turning cuts material off from the component. At milling, however, the material is cut via a rotating tool. Rotating tool means that it is the tool that spins, compared to turning where the workpiece spins. WORKPIECE TOOL The advantage of the tool spinning is that you can create complicated geometries that a turning tool cannot handle. FLAT SURFACES ROUND SURFACES ANGULAR SURFACES ALL ANGLES FREE GEOMETRIC FORM "You can Angle the workpiece at any angle you want. This allows you to produce components with free choice of geometries." LEARN MORE ABOUT MILLING KNURLING WHAT IS KNURLING? Knurling, also known as lettering, originates from the printing of letters on coins. In today's society, knurling means printing patterns or grooves on cylindrical metallic surfaces. The grooves' job is to create a structure that is easy to grip and provides friction. WORKPIECE TOOL When you knurl, you use a lettering tool. This tool has either one or two letter rings, depending on the pattern you want. CROSS-KNURLING STRAIGHT KNURLING DIFFERENT TYPES OF PATTERNS: LEARN MORE ABOUT MILLING FORMING WHAT IS FORMING? Using a forming tool, you can shape the material to the desired shape. This method is fast and efficient, compared to turning the same shape. ​ This tool is mainly used to produce nozzles for fluid flows, hydraulics, or pneumatics, to control flows. WORKPIECE TOOL The forming tool molds the base material to its own shape when pressed and cut against the metal or plastic. Different types of nozzles / nipples: ​ CHASE NOZZLE FLOW NOZZLE TAILORED MADE NOZZLES LEARN MORE ABOUT FORMING THREADING WHAT IS THREADING? A thread is a helical structure that is there to fasten two different objects with each other through an internal thread (female) and an external thread (male). It is the thread that is the basis for fasteners . You can get a thread vertical, horizontal and diagonal. INTERNAL THREAD EXTERNAL THREAD HORIZONTAL VERTICAL DIAGONAL ALL ANGLES We offer all kinds of threads from standard to custom: ​ Left and right thread Metric threads (M) "UNIFIED" Pipe thread (G) NPT (conical thread) LEARN MORE ABOUT THREADING HOLE PROCESSING WHAT IS HOLE PROCESSING?

Mekanisk bearbetning avser en process där material, oftast metaller eller plast, bearbetas och skärs med hjälp av maskiner för att ge den önskade formen och ytfinish man har. Det finns flera olika typer av skärande bearbetning mekaniska kompoenter: Svarvning : Här roteras arbetsstycket medan ett skärande verktyg rör sig längs dess yta för att avlägsna material. Fräsning: Ett roterande skärande verktyg (fräsen) rör sig över arbetsstycket för att ta bort material. Borrning : Ett roterande borrverktyg används för att skapa hål i arbetsstycket. Mekanisk bearbetning kan utföras på en mängd olika maskiner, vanligaste teknologin är CNC-maskiner (datorstyrd numerisk styrning) som kan programmeras att utföra komplexa bearbetningsoperationer med hög precision. Huvudsyftet med mekanisk bearbetning är att omvandla ett råmaterial till en färdig produkt med specifika dimensioner och ytegenskaper. Vad räknas till skärande bearbetning? De bearbetningsprocesser som ingår i skärande bearbetning är: svarvning , fräsning , hålbearbetning , gängning , formning , lättring , driftning , gravering och stämpling Vad innebär skärande bearbetning? Skärande bearbetning är en tillverkningsprocess som även kallas CNC-bearbetning, där material subtraheras med ett skärverktyg ifrån ett grundmaterial.

WHAT IS HEAT & SURFACE TREATMENT? Heat and Surface Treatment is the collective name for a method performed on metals and non-metals to meet certain criteria. These criteria can either be for aesthetic reasons, but are most done to increase durability by: PREVENT WEAR AND TEAR ON THE MATERIAL PROTECTS THE COMPONENT FROM ELEMENTS OF NATURE ELECTRICAL INSOLATION WHY HEAT & SURFACE TREATMENT? Products are heat and surface treated to produce beautiful, durable, and strong components. CORROSION When a metal is in its natural form before it is mined, it has different mineral forms. When the metal is machined and the minerals are refined into a component, it’s not as stable as in its mineral form. Rust, also called corrosion is nature's way of getting the metal to return to its natural mineral form. Surface treatment means that you somehow create a protective layer between the raw surface of the component and the elements of nature, to prevent the minerals from breaking down. CORROSION PROTECTION ELECTRICITY & HEAT It is not only the forces of nature that can break down metals, electricity and high temperatures also affects metal in a negative way. Most metals conduct electricity, which is good for purposes such as electrical cables, but in some cases, you don’t want the metal to conduct current. ​ To prevent the metal from conducting current, the metal can be covered with a surface that does not penetrate the electrons and insulates the component. Electrolytic surface treatment provides a protected film of chromium, nickel, or zinc. If you want the component to conduct electricity well, you can treat the material with a surface such as silver or gold, which is very lively. ELECTRICAL PROTECTION FINISH When a component is treated to be stronger and more durable, it can look ugly. Toughness is not always the only criteria. Since many of our finished products reach consumers, aesthetics is also important. ​ The most important thing is to protect the component from the elements of nature, but in some cases it’s just as important that the product is exposed in a way that satisfies the viewer’s eye. HOW DO I GET A NICE FINISH ON THE COMPONENT? HARDNESS & TOUGHNESS Some base materials do not meet the criteria found on the component when it comes to how strong it should be. Therefore, the component can be given new properties, where they can become harder or tougher via heat treatment. HOW DO I MAKE THE MATERIAL HARD? SOFT & SMOOTH SURFACES When a component is machined, sharp edges can appear. Then you must polish these sharp edges, so they become smoother. While doing this, the mechanical component becomes softer and nicer to hold. HOW DO YOU MAKE THE SURFACES SMOOTH AND SOFT? CLEAN SURFACES A CNC machine uses oil to cool the tools as they cut the raw material. This means that the mechanical component is oily, but also has residues such as swarf and chips, or other particles of matter that the naked eye cannot see. It is then important to clean the product, so it can undergo the next process or be delivered to the customer. Through cleaning, the component also receives thin rust protection that protects it during transportation or storage. HOW TO GET THE COMPONENT CLEAN? HEAT & SURFACE TREATMENT METHODS Which surface treatment you choose for your product is defined by the purpose of the use. It is important already in the engineering stage of a product, to decide how it should be treated or not. HARDENING SURFACE TREATMENT GRINDING DRUM POLISHING WASHING WHAT IS SURFACE TREATMENT? Surface treatment is a method where you apply a thin layer of chemical liquid on the material's surface. This chemical liquid then creates a protective film. Depending on what you want to protect and what material you have for your component, this film can provide different protection: ELECTRO-GALVANIZING PHOSPHATATION ANODISING REQUEST A QUOTE SURFACE TREATMENT WHAT IS DRUM POLISHING? Drum polishing is a method where you put the components in a drum and spin them together with a liquid called compound and stones called chips. With the help of the compound and the chips, you can: SMOOTH SHARP EDGES POLISHING OF SURFACES FOR BETTER SURFACE EVENNESS AND FINISH CLEANING CORROSION PROTECTION DEGREASING REQUEST A QUOTE DRUM POLISHING WHAT IS GRINDING? If a mechanical component has tight tolerances the CNC lathe has difficulty keeping up with. Then you have to use a machine that is able to keep such tight tolerances, and that is a grinder. CIRKULAR GRINDING HOLE GRINDING CENTERLESS GRINDING REQUEST A QUOTE GRINDING WASHING WHY IS WASHING IMPORTANT? By alkaline washing your mechanical components, you can remove unwanted particles such as: ​ OIL SWARFS AND CHIPS DIRT REMOVE OIL REMOVE PARTICLES NON-PERMANENT CORROSION PROTECTION REQUEST A QUOTE HARDENING & HEAT TREATMENT Hardening is a method where the material is heated to a high degree in a furnace to gain new properties that it did not have before. For example, becoming harder, tougher, and more durable. The most common methods of heat treatment are: TEMPERING VACUUM CURING SET CURING HARDENING CARBONITRATION NITRO CARBURETION + AFTER OXIDATION REQUEST A QUOTE HARDENING & HEAT TREATMENT THE SPIDER IN THE WEB Through our network of suppliers in our area , we can provide heat and surface treatment for the components we machine. This means that you don't have to find new suppliers yourself. This leads to reduced freights and higher quality; we call that sustainable! WHAT IS HEAT & SURFACE TREATMENT? HEAT & SURFACE TREATMENT

HARDENING & HEAT TREATMENT SEE OUR HARDENING METHODS HERE WHAT DIFFERENT HARDENING METHODS ARE THERE? What gives the material better properties has to do with the dislocation mobility being redirected in the material. Dislocation is different from material to material and therefore also requires different types of methods to succeed in getting the properties you want. THE HARDENING METHODS AVAILABLE ARE: TEMPERING VACUUM HARDENING SET HARDENING HARDENING CARBONITRIDING NITROCARBURATION + AFTEROXIDATION VACUUM HARDENING Vacuum hardening is a thermal treatment method where tool steel heats the surface access to oxygen and gives hard properties to the material. After the material has been vacuum cured, it must be tempered . Depending on whether you want a nice surface without discoloration, you can make the tempering in the vacuum oven. If there are no specific surface requirements or requirements for the appearance, then you can use the cheaper method, to tarnish in an ordinary tempering furnace. MATERIAL THAT CAN BE VACUUM HARDENING The materials that can be vacuum cured are tool steel in the specifications: SS2260 SS2310 SS2312 SS2303 READ MORE ABOUT TOOL STEEL HERE BENEFITS OF VACUUM HARDENING No oxides present No oxygen presents Limited distortion Clean and bright results DISADVANTAGES OF VACUUM HARDENING Time-consuming Sensitive to disturbances Must be handled correctly and carefully, which requires knowledge TEMPERING Tempering is a process that is usually performed according to some type of hardening method. ​ When you use some type of hardening method, you maximize certain types of properties that the method offers. This makes other characteristics less good. ​ The purpose of tempering as a post process is to change the properties of the material that are less good to become better. MATERIAL Materials that can be tempered:​ SS2260 SS2310 SS2312 READ MORE ABOUT TOOL STEEL HERE BENEFITS Provides new desired properties Reduce the risk of cracking DISADVANTAGES Provides an extra process for the heat treatment, which increases prices and delivery times.

POSOXIZATION SET HARDENING The set hardening task is to apply a hard surface to the soft and easy-to-work steel. These types of steel are too soft and ordinary hardening would not have any effect. By adding carbon, this soft steel also gets the hard properties you want. MATERIAL THAT CAN BE SET HARDEND The materials that can be set hardened are low-alloy steels in the specifications: SS1370 SS2172 SS2514 SS2511 SS1922 SS1914 READ MORE ABOUT ALLOY STEEL HERE BENEFITS OF SET HARDENING Good for low-alloy steels High wear resistance High bearing capacity Good fatigue strength The core retains its toughness DISADVANTAGES OF SET HARDENING Rugged surface Voltages may occur Finishing may be required CARBON NITRIDING Carbon nitriding is a variant of case hardening used for low-alloy steels.

Steel components are usually improved when the hardness is weighed against the toughness. Hardness improves: Life span Durability Load capacity Toughness reduces the risk of: Breakdowns Crisp fracture MATERIAL AS CAN BE HARDEND Most steels can be hardend, but the most common are: SS2140 SS2090 SS2550 SS2258 SS2541 SS1770 READ MORE ABOUT ALLOY STEEL HERE BENEFITS Provides new desired properties Reduce the risk of cracking DISADVANTAGES Provides an extra process for the heat treatment, which increases prices and delivery times.

SEE OUR POLICY WE MANUFACTURE YOUR COMPONENTS , SO YOU DON'T HAVE TO Contract manufacturing, also known as a job shop partner means that a company outsources the production of its products to an external manufacturer like a metal turning workshop. This means that the company doesn't have to invest in its own production plant and equipment, but instead hire a specialist within that segment. ​ Contract manufacturing gives advantages of flexibility, cost savings, and expertise from the manufacturer. With cooperation like contract manufacturing, you as a customer can focus on your core business, like product development and marketing. This gives you the opportunity to scale your business depending on the demand. PORTFOLIO See what type of components we machine for our customers. SEE PORTFOLIO

VIBRATORY FINISHING WHAT IS VIBRATORY FINISHING? WHAT IS VIBRATORY FINISHING ? Vibratory finishing is a surface treatment method, also called trowalizing. By trowalizing metal components you can get several different properties, depending on what you are looking for. The properties vibratory finishing can offer are: DEBURRING OF SHARP EDGES POLISHING FOR BETTER SURFACES AND FINISH CLEANING CORROSION PROTECTION DEGREASING This creates surfaces that become smooth, clean and free from sharp edges. HOW DOES THE METHOD WORK? Vibratory finishing is done by putting the components in a drum. within the drum, the components are vibrated around and rubbed against chips in a liquid called compound. COMPOUND The compound is the liquid in which the components are spun. The function of this liquid varies depending on the purpose but may have properties such as: DEGREASING CLEANING RUST PROTECTION GRINDING POLISHING CHIPS Chips are the physical material that spins around among the components. These chips can vary between: CERAMIC STONES STEEL BALLS PLASTIC CONES The chips are there to separate the components from harming each other, but mainly to: REMOVE SHARP EDGES POLISH UP THE SURFACE EVEN EVENINGS WHAT PROCESSES CAN A VIBRATORY DRUM DO? Thanks to that the vibratory drum is using both compounds and chips as a method, the drum becomes a very universal machine. that one machine allows us to do all these processes: GRINDING POLISHING RUST PROTECTION DEGREASING REMOVE SHARP EDGES SMOOTH OUT IRREGULARITIES GRINDING With the help of a vibration drum, machined components that have visible unwanted lines can be grind down. This grinding is possible thanks to the chips , which rub against the mechanical component and then grind the surface. POLISHING Sometimes mechanical components or fasteners need to be polished. Polishing by hand is both inefficient and expensive. It is therefore both more time-effective and cheaper to polish the details by trowalizing. The surfaces that can be obtained by polishing in a drum are: MIRROR FINISH GLOSSY HIGH GLOSS REFLECTIVE RUST PROTECTION When using materials that are sensitive to rust, it is important to protect the component as quickly as possible. Instead of sending the details to a surface coating company, you can use a compound with rust protection when you trowalizing the pieces. DEGREASING & CLEANING When a mechanical component is machined in a CNC lathe, the machine uses oils or emulsion to cool the tools and the workpiece. This makes the pieces greasy and dirty. One way to solve this is to wash the details in an industrial washing machine . If the parts have to be drummed for other reasons, a process (washing) can be avoided as the drum can do two steps in one. REMOVE SHARP EDGES Rounded edges slide into each other more easily and reduce the risk of injuries. When processing in a CNC machine, there is a risk of getting sharp edges, especially when milling . ​ In the drum, the details are rubbed against the chips , which grind away the sharp edges and rounded corners. REMOVE IRREGULARITIES There are many reasons to smooth out roughness on your CNC machined mechanical component: AESTHETICS LESS FRICTION LESS WEAR QUIET MECHANICAL RUNNING When the drum rubs the part against the chips it becomes smoother and nicer to hold. This is because the drum lowers the RA and RZ values of the product.
