Looking for CNC Swiss screw machining services?

Making production volumes of small complex, machined parts.

Pioneer Service is a Swiss machine shop offering CNC Swiss screw machining services. We make screw machine parts to your specifications.

Our Swiss CNC’s are perfect for machining small complex parts in any volume but become especially cost-effective for production volumes. At Pioneer Service, we provide CNC Swiss machining services to make a wide variety of small parts with complex geometries and tight tolerances. We make parts as small as .045″ (1.1 mm) in any quantity. With our Swiss machining services, the complexities and consistent quality are endless. Once a program is loaded and perfected it can be used over and over again with little downtime or set-up required. We can help with both medium and short run projects and scale up for long running jobs as well.

Our Screw machine equipment includes:

12 CNC Swiss Turning Machines
2 CNC Turning Centers
Brown & Sharpes
Quality & Inspection Equipment

What is Swiss screw machining?

watchScrew machines were first invented in 1865 to efficiently produce watch parts by turning round bar stock and machining the rotating bar with special tooling. The original equipment, patented first by Brown & Sharpe, is a turret style automatic screw machine. It was called a screw machine because it originally was used to make screws and pins, though it has been adapted to make many other kinds of parts. As you may guess, this technology started in Switzerland for the production of famous Swiss watches. Today there are many kinds of screw machines for various types of parts and volumes. Some have CNC (computer numeric control) functionality and others do not.

CNC Swiss screw machines, also called CNC turning machines or lathes, function with a disc cam that rotates tools to work bays within the machining center. The disc cam moves the production part along the tool so that machining always takes place very close to the spindle collet. This is different from other kinds of lathes where the bar stock rotates and the machining can take place anywhere along the stock. When the machining is near the spindle collet, it allows the machine to produce parts with very close tolerances. There is less vibration along the part length as compared with a turret style lathe which has tools move to the rotating part. Because of this, Swiss machining is very good for parts that are long (in comparison to the diameter) with tight tolerances.

This equipment differs from CNC turning centers that have the tooling move to the bar. The less distance a tool is from the workpieces, the less time it takes to make the parts. In the below photo, the machinist is shining his light on the bar stock that will be rotating and articulating according to the program. Right above the bar are the stationary tools that will meet the bar. The more tooling slots available, the more complex the part the equipment is capable of making. Swiss machines come with a variety of tooling options, depending on the make and model. When looking for Swiss screw machining services, it’s great to work with a company who has various types of machines.

CNC Swiss Screw Machining Services with lots of tooling options for complex parts.

The machining takes place right next to the collet, which not only spins the bar but feeds it into the machine to meet the tools. Great Swiss screw machining services make great parts!
