They can create items at high speeds and may have numerous spindles, with a six-spindle machine being the most typical arrangement. A family of automatic lathes for tiny to medium-sized parts is known as a screw machine product. Since they no longer produce screws or screw anything into place, the moniker, "screw machine," is thought to be a little deceptive.

They rotate on a revolving lathe instead, effectively shaving the metal to the appropriate size. A revolving component called a disc cam, which is used in screw machines, converts rotary motion into linear motion or vice versa utilizing one or more spindles. A screw machine runs with close spindle collets, which reduces or completely eliminates deflected debris.

Types of Screw Machines

A disc cam is used in automatic Swiss screw machines to rotate tools in the direction of the workpiece area, which is fixed in place by a number of spindle collets arranged side by side. Computer precision parts can be produced with numerically-controlled machines by using a CNC unit to operate the tools. Swiss screw CNC machines, commonly referred to as CNC lathes, provide numerous axes of motion for quick results.

Although they can be labor-intensive to set up properly, screw machines—both automatic and CNC-driven—are economical when producing numerous pieces. They frequently aren't the best option for sporadic prototyping. However, they are a flexible option when making parts out of many sorts of metals because of the large range of metals they work with.

Differences Between Mechanical and CNC Screw Machining

Given that each machine type has benefits and drawbacks, choosing between a mechanical screw machine and a CNC screw machine could prove challenging. Traditional screw machines, for instance, cost more upfront for smaller runs but can efficiently manufacture big volumes of output. Additionally, they work much more quickly than their CNC-operated competitors. Although slower, CNC machines are more cost-effective for small batches and can maintain tighter tolerances.

Screw machining achieves precision and tolerances that are difficult to match. Other metal fabrication and forming techniques rarely produce items with a screw machine's level of excellence. Screw machines are perhaps the best tools available for creating turned pieces.

Benefits of CNC Screw Machine

  • An automatic Swiss screw machine may not be able to provide the same level of control as CNC machining. The usage of several axes with the CNC unit enables the use of more tool sets for milling and turning. With the use of CNC capabilities, cycle times may be shortened and more intricate parts can be produced. Using a CNC Swiss machine, several tasks can be completed more quickly. A CNC Swiss screw machine has an accuracy range of 0.0002 to 0.0005 inches and can rotate an item up to 10,000 RPM. A CNC Swiss lathe is not only more accurate, but it also produces less waste and offers greater flexibility when cutting a particular product.
  • Two goods could be produced at once on a single-spindle machine. When compared to a single-spindle, a multi-spindle machine typically has six main spindles, enabling users to produce six times as much. As a result, manufacturing times are shortened, and space and energy consumption in the factory are reduced.
  • Electricity savings can assist in offsetting the expenses of upkeep, improving safety and equipment, and having greater space can open up prospects for more equipment and worker safety. Overall, the advantages of multi-spindle screw machines result in time and money savings.
