Multiple Spindle Screw Machines have been considered the back bone of high volume turned parts since the early 1900’s. They consist of 5 to 8 horizontal lathe spindles with horizontal end working attachments and 4 to 6 cross slides with attachments to form or thread the outside of parts. Various attachments are available to due various secondary operations. In our view Multiple Spindle Screw Machines are best for standard parts not requiring extensive secondary operations. Typical cycle times are 4 to 15 seconds. This is approximately the same amount of time required to feed barstock or to load a blank in CNC machinery.

Disadvantages of Multiple Spindle Screw Machines include tooling expense and long setup time required. Multiple Spindle Screw Machines begin to be a cost effective option when annual production volumes (or part families) exceed 50,000 pieces.

History of Multi-Spindle Screw Machines

Multi-spindle screw machines have a rich history that spans over a century. They were initially developed as a solution to the growing demand for fast and efficient production of small parts—particularly screws and bolts—during the industrial revolution. With the introduction of multi-spindle screw machines, manufacturers could produce large quantities of parts quickly, which revolutionized mass production and paved the way for modern manufacturing practices.
As technology advanced, so did multi-spindle screw machines. They became more sophisticated, and new features were added to accommodate larger and more complex parts.
Today's multi-spindle screw machines are highly automated and utilize computer numerical control (CNC) technology to ensure precision and efficiency. The machines can operate with multiple spindles, each with its own cutting tool, allowing for simultaneous machining of multiple parts. This feature drastically reduces production time and increases output, making multi-spindle screw machines the go-to choice for high-volume precision machining.
The evolution of multi-spindle screw machines has had a significant impact on various industries, including automotive, aerospace, medical devices, and electronics. These machines have made it possible to produce intricate parts with exceptional precision, speed, and consistency, improving product quality and cost-effectiveness.

Applications of Multi-Spindle Screw Machines

Multi-spindle screw machines are an indispensable tool in modern manufacturing and have a wide range of applications. Their ability to produce complex parts quickly and accurately makes them an essential part of industries such as:
  • Automotive: In the automotive industry, multi-spindle screw machines are used to produce parts such as engine components, transmission parts, and suspension parts. These machines can produce high volumes of parts with consistent quality, which is essential in the automotive industry.
  • Aerospace: In the aerospace industry, multi-spindle screw machines are used to produce parts such as turbine blades, landing gear components, and hydraulic fittings. These parts are critical to safe and reliable aircraft operation, and their production requires the highest levels of precision and accuracy.
  • Medical Device: In the medical device industry, multi-spindle screw machines are used to produce parts such as surgical instruments, implant components, and diagnostic equipment. These parts must meet strict regulatory requirements and be produced with high precision and accuracy to ensure patient safety.
  • Electronics: In the electronics industry, multi-spindle screw machines are used to produce parts such as connectors, switches, and circuit board components. These parts are critical to the operation of electronic devices and must be produced with high precision and accuracy to ensure reliable performance.
At Griner Engineering, we have experience producing a wide range of parts using multi-spindle screw machines, including connectors, fasteners, fittings, and more. Our expertise in precision machining allows us to produce high-quality parts quickly and efficiently, making us the right choice for your machining needs.

Advantages of Multi-Spindle Screw Machines

In addition to faster production and high precision, multi-spindle screw machines offer several other advantages. For example, they can handle various materials, including brass, steel, aluminum, and plastics, making them versatile for multiple industries. Moreover, because multi-spindle screw machines are highly automated, they can operate for extended periods without constant supervision, reducing labor costs.
Another advantage of using multi-spindle screw machines is that they can be easily programmed for different jobs, which means that they can quickly switch between producing different parts. This flexibility is particularly useful for companies that need to produce multiple parts with varying specifications quickly.
Furthermore, because multi-spindle screw machines use several cutting tools simultaneously, they can perform multiple machining operations in a single setup. This reduces the need for multiple machines, tools, and operators, thereby lowering overhead costs for manufacturers.
