SWISS CNC Machining

ProtoTech Machining specializes in precision Swiss CNC Machining, delivering intricately crafted components with unparalleled accuracy and quality. 

Swiss Machining

We excel in mid to high-volume production runs. However, a significant aspect of our success lies in our expertise in high mix low volume production and our capability to run and ship blanket releases. We pride ourselves on accommodating various order sizes, and there are no minimum order quantity requirements. Nonetheless, it is essential to understand that the part price is influenced by the production volume, as setup costs cannot be spread across a large number of parts. Please keep this in mind while planning your production needs.

We machine rapid prototypes and low & large-volume production orders for customers in multiple industries: medical devices, aerospace, automotive, defense, electronics, hardware startups, industrial automation, machinery, marine and robotics, and many more.

We support high mix, low volume, and high volume production runs.

When it comes to manufacturing precise parts with tight tolerances or intricate multi-axis features, our preferred choice is Citizen Swiss machines. They have proven to be reliable, delivering consistent and dependable results. With an impressive lineup of over a dozen CNC machines in our production Swiss machine shop, we have the capacity to handle a wide range of projects, from 1-1/2” diameter components to micro machined parts under 1/16” in size. All of our turning centers are equipped to produce fully finished parts efficiently, even overnight, with minimal risk of operator error. Whether it’s supporting high mix, low volume production or handling high volume projects with stringent tolerances, these machines excel in precision. One of the key advantages of these machines is their ability to manufacture complex turned parts with fewer operations, effectively reducing handling time and associated costs. This enhances our overall production efficiency and helps us deliver superior products to our customers.

What Is Swiss CNC Machining?

Swiss CNC machining is a specialized process to machine small, high precision turned parts. A Swiss CNC machine, also referred to as a Swiss automatic lathe, Swiss screw machine, or Swiss-type lathe, was originally designed for the Swiss watchmaking industry. Over the years, the Swiss-style turning machine has been refined to be widely used in various industries for high-volume, high-precision manufacturing – and for good reason.

A Swiss-style lathe is a type of machine that cuts bar stock fed through a guide bushing while the tools keep stationary. The collet is recessed behind the guide bushing so that the bar stock held in it will have better support and will not directly be exposed to the lathe bed and the tooling, so the machine can process the material rapidly and tightly. Also, it plays a great role in decreasing tool deflection and vibration while increasing parts accuracy since the cutting tool can work nearer to the bushing.

How Does A Swiss-type Lathe Work?

A conventional turning machine has a fixed headstock that holds the spinning workpiece when a cutting tool moves across to machine the outer diameter. However, in a Swiss CNC turning center, it employs a sliding headstock that feeds bar stock through a guide bushing in the Z-axis towards the stationary cutting tool.

In the turning operation, clamped onto the chuck or collet in the headstock, the bar stock is located radially and precisely. The headstock moves back and forth along the z-axis, taking the bar stock with it. The turning tools, carried on the gang slide, always engage the bar stock close to the bushing, usually within 1 to 3 mm, thus providing the greatest degree of support and decreasing vibration and tool deflection consequently. And continuous feeding is achieved by the movement of the spindle and the supply of the guide bush.
