Screw machines are generally defined as lathes, which are used to turn small parts. These mechanisms are typically found in manufacturing plants and industrial houses. Though the term might confuse you a little bit, these machines don’t actually screw or thread anything. They instead help on spinning a product quickly, allowing you to perform different tasks such as cutting, deformation, drilling, facing, knurling, and sanding.
There are two known types of screw machines today: The Turret, which is commonly called as Brown & Sharpe, and the Swiss turning machine, which was named after its place of origin. Both machines have the same purpose, but they function differently.
Between the two, Swiss screw provides more precision. This is the reason many manufacturers prefer them than the other.
Two Types of Swiss Screw Machine
The two main types of Swiss turning mechanism are the automatic and CNC. To understand how these two systems works, here’s a quick definition:
- Automatic – The automatic mainly works with a disc cam, which rotates the tools to the workpiece. Its actions can be controlled automatically and move the tools in a spiral motion to account for any longitudinal discrepancies to the product. It keeps off deflected debris from becoming a problem.
- CNC – Like the automatic, CNC operates the same way except the fact that it is controlled by a CNC unit (hence the name). It has better direction and features more sets of tooling, which shorten the amount of time spent on one product. The only downfall for this system is it lacks precision and speed.
There are still many things you need to understand about screw machines. For starters, you may focus on studying the information presented above. If you want to maximize the benefits of these mechanisms, you can either research or talk to an expert for more information.
