What Is Swiss Screw Machining?

Swiss screw machining is a machining (subtractive manufacturing) process that uses Swiss-style machining equipment. It is distinguished from other machining equipment by using a guide bushing to reduce the distance between the main spindle and the cutting tool. Because of this design difference, the workpiece bends less and, as a result, deflects less at the cutting surface. The process is frequently used for high-volume precision manufacturing small cylindrical parts and products.

How Does Swiss Screw Machining Work?

  1. In Swiss Screw Machining, a round bar stock is loaded into the machine, held in place by a guide bushing to minimize vibrations.

  2. The machine’s headstock, holding the workpiece, slides along the Z-axis allowing precise cuts while the tools remain stationary, a unique feature compared to conventional lathes.

  3. These machines are equipped with various tools to perform operations like turning, drilling, boring, threading, and milling in one setup, enhancing efficiency.

  4. Once machining is done, a cut-off tool separates the finished part from the bar stock, which is then ejected, and the bar stock is advanced for the next part.

  5. To mitigate the heat generated by machining, a coolant system is used to maintain the precision of parts and extend tool life.

Advantages of Swiss Screw Machining

Swiss Screw Machining comes with several distinct advantages, which include

Precision

Swiss Screw Machines can maintain extremely tight tolerances, producing high-precision parts ideal for industries like aerospace, medical, and electronics.

Efficiency

The design of Swiss Screw Machines, allowing for simultaneous operations, enhances machining efficiency and production speed.

Versatility

These machines can handle a wide range of materials, including various metals and plastics, making them applicable to a wide range of industries.

Complex & Long Part Production

Swiss Screw Machining is suitable for producing small, complex parts and long, slender parts with strict dimensional tolerances and surface finish requirements.

Scalability

Swiss Screw Machines excel in large production runs, offering swift and precise manufacturing by performing multiple operations concurrently, boosting overall productivity and quality.

Consistency

The automated nature of Swiss Screw Machining allows it to produce a high volume of parts with excellent consistency and repeatability, crucial in industries where parts must meet exact specifications.

Suitable Materials for Swiss Screw Machining

Metal

It’s lightweight, has good machinability, and is used extensively in industries like aerospace, automotive, and electronics.

Due to its strength and resistance to corrosion and heat, it’s widely used in medical, aerospace, and food processing industries.

It’s easy to machine and has good corrosion resistance, making it ideal for fittings, valves, and electrical components.

It’s excellent for electrical components due to its electrical conductivity.

Known for its strength, lightness, and resistance to corrosion, it’s often used in the medical and aerospace industries.

Depending on the requirements, different grades of steel can be used for different applications.

Plastic

Used for parts requiring high stiffness, low friction, and excellent dimensional stability.

Known for its wear resistance, flexural strength, and good machinability.

A high-performance plastic with excellent strength, temperature resistance, and chemical resistance.

Also known as acrylic or Plexiglas, it’s transparent, lightweight, and weather and UV light resistant.

Also known as Teflon, has excellent chemical resistance and a low coefficient of friction, making it suitable for a variety of high-performance applications.

Known for its high heat resistance, high strength, and excellent dimensional stability, it’s often used in demanding applications in industries like aerospace, medical, and electronics. It is also inherently flame resistant.

This material is versatile, chemically resistant, and low-cost.

Chosen for its strength, lightness, and chemical resistance, it’s often used in automotive and consumer goods.

Available Finshes for Swiss Machined Parts

The finishing option with the shortest turnaround time. Parts have visible tool marks and potentially sharp edges and burrs, which can be removed upon request.

Smooth machining is similar to a ‘As machined’ finish, but with less visible machine marks. Parts are machined at a lower feed rate, with no hand polishing.

Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment.

Machined parts are bead blasted with glass beads which results in a uniform grainy texture and reduced machining marks.

It is a process that tumbles vibrating media on machined parts to remove sharp edges and burrs.
Tumbling can be used to remove machine marks from exterior surfaces.

This is a finish of applying powdered paint to the components and then baking it in an oven, which results in a stronger, more wear- and corrosion-resistant layer that is more durable than traditional painting methods. A wide range of colors is available to achieve the desired aesthetic.

Black oxide is a conversion coating that is used on steels to improve corrosion resistance and minimize light reflection.

Type II  improve corrosion and wear resistance of components. Parts can be anodized in a variety of colors, the most common colors are clear, black, red, and gold, and is typically associated with aluminum. 

Type III (Hard Coat) is thicker and adds a wear-resistant layer to Type II’s corrosion resistance.

Chromate Conversion Coating is ideal for increasing the part’s corrosion resistance while maintaining its conductive properties. Can leave surface yellow/gold. It is a good base for paint or adhesive applications.

Include Nickel Plating, Silver Plating, Gold Plating, Zinc Plating, Chrome Plating, Tin Plating and etc, it is ideal to reduce corrosion, improve appearance and function of solderability and electrical conductivity.
