How Does a Spindle Machine Work?

How does a spindle machine function?

The spindle rotates inside the machine, and this drives the inside components. In the machine, the spindle is housed in a spindle support. This holds the spindle in place and rotates with it. At the front, there’s a feed mechanism that feeds the material into the machine and controls the feed rate for the material. At the back, there’s the drive mechanism. This powers the machine and transfers the rotational power to the components inside.

The inside components move at high speeds as the spindle revolves. The components include knives, cutters, and even magnets. The knives on the cutters cut the material, and the magnets secure the pieces of material together for further processing.

Types of spindles

  • Rotary spindles – This is the most common type of spindle used in manufacturing. It offers high speed and high torque, making it ideal for high-speed cutting of materials like plastic, wood, and paper. Generally, it is either a CNC or an SNC rotary spindle.
  • Screw extruders – The screw is replaced with a barrel. The barrel rotates inside the machine, and the material is fed into it from the front. The material melts inside the barrel, and the screw extruder is best for processing food materials.
  • Sabatier knife rolls – A knife roll is a mechanical knife unit that rotates inside the machine in the same direction as the spindles. As the material is fed into it, the knife rolls cut the material.

The working principles of a spindle machine

  • Material – The material is fed into the machine, either as a roll or a loose piece. A spindle machine generally has one feed mechanism; if you feed the material into it manually, it is called a punching system. The feed mechanism is what controls the feed rate for the material.
  • Feed System – The feed system takes the material from the feed mechanism and feeds it into the spindle. The feed system consists of a feed chute and a feeder. Depending on the type of spindle machine, the feeder may be integrated into the machine or a separate component.
  • Spindle – The spindle takes the material from the feed system and stores it. A spindle machine can have one spindle or multiple spindles. The spindle or spindles rotate inside the machine.

Applications of Spindle Machines

  • Paper and board – The paper and board industry uses spindle machines to make paper and board products. The paper material is fed into the machine, one after the other, and cut at high speeds by the rotary knives.
  • Food processing – Spindle machines are best suited for food processing. These include extrusion and co-extrusion. During co-extrusion, thermoplastic polymers, resins, and natural fibers are mixed inside a barrel and pushed through a die to form a homogeneous material.
  • Textiles – Spindle machines are best suited for making knitted and woven fabrics, such as yarn and fabric. The yarn is fed into the machine from the front and is wound on to a spool. A spindle machine is known as a Jacquard machine.

Key Takeaway

Spindle machines are used in industries such as plastics, textiles, and even food processing to process various materials at high speeds. These materials are fed into the machine, one after the other, and processed to obtain the desired end product.

The spindle, which is technically known as the screw, is the bar that runs through the inside of the machine. The bar is made of a material such as steel or aluminum, and is housed inside the machine’s mainframe.
