CNC Swiss Screw Machine: Types, Benefits and Practical Applications
An automatic lathe is what is known as a CNC Swiss screw machine. It is capable of producing large quantities of precision turned components in a precise and efficient manner.
In this article, we will discuss the many advantages it offers over its corresponding lathe counterpart. In addition to this, we will also cover its many applications.
1.What are the main types of CNC Swiss screw machines?
Automatic and Computer Numerical Control (CNC) Swiss Screw Machines are the two most common types discussed below:
1) Automatic Swiss screw machine
The tool holder of an automatic Swiss screw machine is arranged radially along the spindle, and the tailstock of the machine is coaxial with the spindle. It is ideal for rapid mass production of tiny, high-precision parts.
To account for variations in workpiece parallelism, a disc cam repositions the headstock and moves the tool radially. The tight spindle chuck of the automatic Swiss screw machine eliminates chip deflection and enables the machine to glide over any obstructions.
2) CNC Swiss screw machine
A CNC (Computer Numerical Control) Swiss Screw Machine is a type of Swiss screw machine that offers increased production efficiency and precision. Multiple tools can be used to perform machining simultaneously and in rapid succession. During this process, the workpiece is turned simultaneously with the lathe.
CNC screw machines are very adaptable in terms of application. Compared to the more common “single-spindle” screw machines, this machine can accommodate a wider variety of fixtures and has dual spindles.
Automatic Swiss screw machines and computer numerical control (CNC) Swiss screw machines are low-cost and highly adaptable, making them ideal for long-term projects. Many machines can be operated by only one operator once they are properly equipped and programmed, making them very cost-effective for long-term projects.
Because the chuck, base plate, and tooling all fit closely together, machining operations can be performed more accurately.
2.What is special about CNC Swiss screw machines?
As the name suggests, CNC Swiss screw machines were developed by watchmakers in Switzerland in search of more precise cutting tools. The working principle of this machine is that the part to be manufactured is mounted on a rotating slide, which then turns, allowing the screw machine to cut the part to the required specifications.
Some of its special features are summarized below:
- There is a micrometer on the tool holder for adjustment
- Large structure, short tool stroke, high rigidity
- High-precision output
- Extremely short cycle time
- Without moving the tool, the workpiece can be moved axially relative to the tool to form features along the length of the tool
3.What are its advantages over other lathes?
The precise operation capability of the CNC Swiss Screw Machine is just one of its many advantages. The CNC Swiss Screw Machine meets the needs of micro components that are usually not handled by different computer numerical control machines. All other CNC machines cannot match the cutting accuracy of this machine (with a tolerance of 0.0002 inches at a speed of 10,000 rpm).
In addition to precise cutting, it has other advantages, including:
- Because the tools are compactly arranged, it is possible to move from one tool to the next in one second or even less.
- With the simultaneous collaboration of up to five tools, the time spent on operation can be reduced by half.
- The Swiss Screw Machine can accommodate up to 20 tools, which makes the machine versatile and makes it a popular choice.
- Since it provides a perfect surface finish, there is no need for any additional finishing steps.
- Milling, drilling, and sawing are some of the secondary machining processes that can be performed.
- The time required for setup is significantly reduced.
- An efficient and time-saving method of maintaining quality.
4.What products does the CNC Swiss Screw Machine produce?
Although the name of the CNC Swiss Screw Machine suggests its purpose, it makes more than just screws. It produces a wide range of parts and products through a variety of cost-effective mechanical and CNC machining methods.
Products produced by the CNC Swiss Screw Machine include:
- Splines
- Spins
- Fittings
- Keyways
- Tire pressure gauges
- Metal knobs
- Threaded rods
- Specialty fasteners
- Miniature medical devices
- Custom and standard bio-implants
5.What are its uses and applications?
Today, CNC Swiss screw machining is widely recognized as an effective method for manufacturing precision parts and components used in a variety of industries, including:
- Medical
- Aerospace
- Military
- Automotive
- Electronics
- Agriculture
- Hydraulics
- Construction
- Energy Equipment
- Musical Instruments
The automotive industry relies heavily on CNC Swiss screw machines, but they have many other uses. When automakers produce thousands of vehicles per day, the ability to manufacture large quantities of parts at a low price is critical, and Swiss screw machines are why.
CNC Swiss screw machines are used in the electronics industry because of their high precision. The high-speed cutting capabilities of CNC Swiss screw machines are especially useful in the electronics industry, which often uses a variety of metals and materials. This is true regardless of the density of the material being cut.
Although CNC Swiss screw machines were first found in the watchmaking industry, they have since found applications in many other fields. CNC Swiss screw machines are a highly sought-after piece of equipment because of their ability to cut extremely fine patterns on a variety of materials.
When this cutting capability is combined with computer-aided motion control, the potential uses are nearly endless. This is why industries such as the automotive industry rely on CNC Swiss screw machines to produce their components.
