About CNC Machining
CNC machining is a process where computer-controlled machines cut and shape materials like metal, plastic, and wood. We use this method to create prototypes and production parts for various industries, including automotive, aerospace, and medical.
CNC machining offers high precision and repeatability, making it ideal for creating intricate parts. Beska’s CNC machining can handle a variety of materials and provides fast production times and consistent quality, making it essential for modern manufacturing.
3D printing builds parts layer by layer, adding material to create the desired shape. CNC machining, on the other hand, starts with a solid block of material and removes sections to form the part. 3D printing is great for complex designs and rapid prototyping, while CNC machining is best for durability, precision, and material versatility.
In our CNC machining process, we often use both aluminum and stainless steel. Aluminum is lightweight and easy to machine, making it suitable for applications where weight is a factor. On the other hand, stainless steel is heavier but offers higher strength and corrosion resistance, making it ideal for more demanding environments.
At Beska, we use both 6061 and 7075 aluminum in our CNC machining. 6061 aluminum is versatile and easier to work with, offering good strength and corrosion resistance. 7075 aluminum is stronger and harder but can be more challenging to machine, often used in high-stress applications like aerospace.
Bronze is typically harder and more wear-resistant, making it suitable for heavy-duty applications. Brass is softer and easier to machine, often used for decorative parts and applications requiring good electrical conductivity.
Plastic CNC machining is a great choice for making parts because plastic parts are lightweight, easy to work with, and usually cheaper than metal parts. At Beska, we use CNC machining to create plastic parts that fit a wide range of needs, making it a favorite for engineers and product teams.
Thermoset plastic, once molded, cannot be melted and reshaped, making it ideal for parts that need to retain their shape. Thermoplastic, on the other hand, can be melted and reformed. It is often used in injection molding.
The best plastic for CNC machining depends on what you need the final product to do. Softer plastics are easier to machine but might not be as strong as harder plastics, which are necessary for more demanding applications. Here are some common plastics we use in our CNC machining but not limited to:
- Polyethylene (PE): Lightweight and durable.
- Polypropylene (PP): Resistant to chemicals and moisture.
- Acrylonitrile Butadiene Styrene (ABS): Strong and impact-resistant.
- Polycarbonate (PC): Very tough and transparent.
- Ultem (PEI): High strength and heat resistance.
About Metal Stamping
Metal stamping is a process we use to shape or cut unheated sheet metal using a tool and die mold or stamping press. Our stamping presses can perform various techniques like punching, embossing, bending, flanging, and coining to create the exact shapes you need.
Deep draw stamping is a technique we use to produce hollow metal components. At Beska, we achieve this by pulling and stretching the metal through a die with a cavity. The depth of the part is determined by how many times the metal is drawn through the die.
In progressive die stamping, we use a series of stamping dies to cut, punch, bend, or perform other operations on a single workpiece. At Beska, this process continues until the finished part exits the final station, allowing for efficient and consistent production.
At Beska, we use various metal fabrication techniques to create specific shapes from metal sheets, bars, or rods. These include:
- Extrusion: Forcing metal through a narrow die to produce a round tube cross-section.
- Forging: Shaping metal by striking it with force in a die or with a hammer.
- Machining: Cutting, drilling, carving, and other shaping operations to remove excess material.
- Milling: Using CNC equipment for precise, multiple-axis cutting.
- Turning: Rotating parts on a lathe while a stationary blade removes unwanted material.
- Punching: Striking metal to indent or perforate it according to specific designs.
- Welding: Connecting separate metal parts through heat and/or pressure.
Metal stamping offers several benefits including:
- Quick production times
- High precision in parts
- Uniform quality across parts
- Applicable to various designs and industries
- Efficient use of materials
- Cost-Effective
At Beska, we determine the best materials for metal stamping based on their characteristics and how well they can be stamped or machined. The function and performance requirements of the application are also considered. For example, office metal baskets might not need high-performance steel, while industrial kitchen counters require food-grade stainless steel. Here are some common materials we use:
- Ferrous Metals: Steel, stainless steel, carbon steel.
- Nonferrous Metals: Aluminum, brass, bronze, zinc.
- Custom Alloys: Beryllium copper, beryllium nickel.
- Precious Metals: Gold, silver, platinum.
At Beska, we choose the best metal stamping process based on achieving the desired results with the fewest steps, minimal scrap material, and cost-effectiveness. Reusing existing dies or utilizing progressive stamping for large production runs can save time and money in the long run.
About Galvanized and Galvannealed Steel
Galvanized steel is coated with a layer of zinc to protect it from rust and corrosion. On the other hand, galvannealed steel goes through an extra step called annealing after being galvanized, which forms a zinc-iron alloy. This makes it even more durable and resistant to corrosion. At Beska, we use both types of steel to match the specific needs of your project.
Think about where and how the steel will be used. Galvanized steel has a shiny finish, making it good for visible parts like solar panel mounts. Galvannealed steel has a duller finish and is more durable, making it better for internal parts that need to withstand tough conditions. Our team at Beska can help you decide which type is best suited for your project’s requirements.
Both types of steel can lose some of their corrosion resistance at the cut edges, making them prone to rust. At Beska, we suggest that welding these steels requires good ventilation because of the toxic fumes and needs to be done carefully to avoid sparking. Also, finding thicker plates of these steels can be difficult, which might increase costs and lead times.
To improve the corrosion resistance of galvanized or galvannealed steel, we can use cold-rolled steel and apply a zinc coating after fabrication. This additional coating helps protect the cut edges from rusting. While this process can increase the overall cost and lead time, it provides enhanced rust resistance, making your parts more durable and reliable.
