Complete guide to CNC Swiss machining

In 2021, the global Computer Numerical Control (CNC) machine market size was $56.40 billion. Given how fast, precise, and automated this manufacturing technology is, it’s hardly surprising that the global machine market is expected to grow in the coming years. As the demand for CNC machining grows, the demand for Swiss machining, a manufacturing process that falls under the overall umbrella of CNC machining, will also rise.Get more news about Automatic Cnc Lathe,you can vist our website!

As with traditional CNC machining, Swiss machining is used with metal and plastic, offers fast production times, and can produce complex parts with tight tolerances. It’s an incredibly efficient, precise, and repeatable manufacturing process, though it differs in several ways from traditional CNC machining.

In this guide to CNC Swiss machining, we’ll go over what you need to know to decide whether Swiss machining is best for your project.
What is Swiss machining?
Originally developed to produce intricate watch parts for the Swiss watchmaking industry in the late 19th century, Swiss screw machines required a skilled operator who could turn handles and push levers to form the desired part. However, thanks to today’s CNC technology, Swiss machining is highly automated and can repeatedly produce complex geometries at tight tolerances with extremely fast cycle times.

As a subset of turning machines, also known as lathes, Swiss machines have stationary tools and a workpiece that can turn and move along the Z-axis, allowing for the creation of round and cylindrical parts. However, its sliding headstock and guide bushing set Swiss machines apart from other turning machines. The sliding headstock feeds the bar stock through a guide bushing, which supports and stabilizes the bar stock near the cutting point. This helps prevent workpiece distortion and enables the machine to accurately create different diameters, complex holes, hex edges, slots, and threads without the need for multiple setups or additional equipment.

When it comes to making parts, Swiss machining is the ideal production method for manufacturing high volumes of small components that require complex turning. Swiss machines are also better suited for machining long parts than traditional CNC turning machines, as they are less likely to cause deflections.
Additionally, traditional CNC lathes generally have two, three, or four axes, but Swiss machines often have five, seven, or more axes, enabling operators to quickly machine even the most complex parts. Instead of performing multiple operations or using several setups on numerous machines, manufacturers can often do the job with one Swiss machine and fewer setups. It’s also worth noting that many Swiss machines can perform several tooling operations simultaneously, whereas traditional lathes usually complete one operation before moving on to the next, which can help further accelerate production.

By using a Swiss machine, companies can enjoy a reduction of secondary operations and tool changes, reduced labor costs, and faster turnaround times, all without sacrificing part quality. Since the bar stock is firmly supported, tolerances are tight and complex parts with thin walls or delicate features can be repeatedly manufactured.
