Swiss screw machines are a type of automatic lathe used to manufacture precision parts. Swiss screw machines are programmed to manufacture high quantities of precision metal and plastic parts. These machines are usually run 24/7 and require minimal intervention to increase production speed and lower costs.
At Spex, we use various screw machines, including Swiss screw machines, Davenport screw machines, and multi-spindle, depending on which one fits your project needs the best. Each machining process has different abilities and benefits.
In this article, we’ll explain 5 benefits that Swiss screw machining offers:
Screw machines have been used since the 1800s to mass-produce identical parts. Today, Swiss screw machining are even more efficient and used worldwide to produce millions of metal and non-metal components every day.
Swiss screw machines can take longer to set up, but once they’re running, they can continue to produce parts 24/7. Outside of the initial programming, the process are automated and require minimal work from machinists. A large amount of raw materials (bar stock) can be held in a bar feeder and keep the production running for hours.
These machines also preform a number of cuts, drilling, and slotting, so complex parts can go from raw material to finished component without needing a second or third machine. Swiss machines also move the material and the tool at the same time to speed up the process. This reduces customer wait times, especially when they need thousands or millions of identical parts.
Swiss screw machines are more efficient and require fewer man hours to produce high quantities of parts. This process isn’t ideal for making a prototype, but when a lot of identical parts are needed, the process becomes faster and less expensive.
This is ideal for industries who need highly precise parts and want to keep costs as low as possible. The automotive, aerospace, defense, and medical industries all benefit from the lower costs and can pass the savings on the consumer.
Swiss screw machining offers a great range of material and design abilities. Swiss screw machines are capable of machining various grades of metal, and polycarbonate with high precision. They also have low levels of deflection which makes them ideal for machining harder metals like stainless steel, Monel, and Hastelloy.
Swiss screw machines can perform very precise cuts and drills. This machining process is one of the most precise and ideal for machining smaller parts. The part surface can also be finished by the screw machine, eliminating the need for a second finishing operation. Depending on the tooling, they can spin parts at 10,000 RPM and cut and drill parts within a 0.005mm (0.0002in) tolerance.
Using a Swiss screw machines is more precise compared to a turret machine because of the precise calculations of the CNC controller, which adjusts and corrects tooling operations while it’s running.
Unlike 3D printing, CNC machining is always a reductive process. This means that metal is shaved off and removed from the raw material to produce the finished product. This does produce some scrap metal, which is collected in bins and recycled later on.
The capabilities of Swiss screw machines help reduce waste by maintaining high precision and lowering the number of mistakes and parts that are unusable by customer. Because Swiss screw machines can perform multiple functions simultaneously, there is fewer labor hours spent on production.
Every industry that uses small precision parts will benefit from the vast capabilities of Swiss screw machines.
Spex produces a huge variety of parts with our Swiss screw machines. Some of these parts include:
These parts are used in a wide range of industries, which include:
