Today there is an increasing demand for advanced procedures and machines that have the capability to produce high-quality precision parts at low cost. This demand has led to the invention of new types of machines and other machines are upgraded to increase or improve their capabilities. The Swiss screw machines are a type of machining equipment that has been developed with the sole purpose of machining components with great precision and efficiency. Are you interested to know how these machines work? The following post will help you understand the detailed working of the Swiss screw machines.
How Do Swiss Screw Machines Work?
It is not that difficult to understand how these Swiss screw machines work. Here are some steps involved in the working of these machines.
Step 1: Holding the Workpiece
This is the first step in the working of these screw machines. The headstock in a conventional lathe is fixed. A chuck or collet is used to hold the workpiece in place. This chuck is extended into the enclosure of the machine as a cantilever. Alternatively, it can also be supported by the tailstock on the end.
Step 2: Passing of Bar Stock
The chucking collet provides a passage for the bar stock to pass through it. The bar stock passes in the headstock which clamps it.
Step 3: Locating the Bar
The bar passes through the guide bushing and then emerges into the tooling area. During the machining, the bar is then located radially by the tooling area.
Step 4: Movement of Headstock
The Swiss screw machine has a headstock that moves. This distinguishes these machines from other types. The headstock moves back and forth along with the bar. This movement is performed by the headstock in the Z direction.
Step 5: Provision of Feed for Cutting
The gang slides of the machine feature turning tools. These tools make contact with the bar. The distance between this contact and the guide bushing is minimal, i.e. within the range of 1 mm to 3 mm. The bar moves in such a way that feed is provided for cutting.
Where are Swiss Screw Type a Health Equipments Parts Used?
The parts machined using the Swiss screw machining technique are used in a variety of industries, including aerospace, electronics, defense, etc. The most common applications which use these parts are as follows:
Fasteners used in medical applications
Grommets and bobbins
Contact pins for electronic components
Collets for watch balance springs
So, this is how these machines work. Swiss screw machining is preferred by most industries due to the benefits offered by this technique. High precision can be obtained by implementing this method.
