The standout feature of Central Machines continuous motion assembly machine is a high production rate. These machines are best suited for smaller parts requiring simple operations executed in multiple steps.
Once the design criteria has been established, our engineers and machine builders will custom design innovative machinery to meet your high volume production needs. Our continuous motion assembly machine equipment provides excellent repeatability, cycle after cycle, due to our reliance on mechanical motions. Our machines are built in-house, which ensures customers get reliable machines and one-stop accountability. Our machine shop is outfitted with all the conventional and CNC equipment necessary to manufacture all components of our multiple piece assembly machine in house.






Our machines are designed to be ergonomic and user friendly from programming to final unloading. A color display touch screen panel is the main user interface with the machine.
From each and every machine our customers can expect longevity and reliability due to the use of mechanical and servo driven motions. Our skilled workforce is all under one roof, allowing for complete construction and product accountability within our shop. We use both conventional and state-of-the-art CAD/CAM and wire EDM machines to fabricate the components.

General Machine Description
The multiple piece assembly machine is a self-contained unit, featuring feeder bowls, and inline tracks. The machine is configured with multiple continuously rotating dials, mounted horizontally to transfer the product through the assembly, testing, and inspection processes.The machines include the following standard features:
- Feeder bowls to orient product.
- Inline tracks to feed product to the continuous motion assembly machine dials.
- The machines can be configured with upper, lower, and horizontal cam-driven tooling.
- The lower dial tooling can be equipped with cam-driven spindles with tooling.
- An outer cam will allow each spindle to move up and perform an operation.
- The upper tooling dial can be equipped with cam-driven spindles with tooling.
- Shift register tracking system will monitor good and bad parts through the system.
- Touch screen type operator control panel with message display to indicate functionality and spindle monitoring.
- If the product fails any test or inspection, the product will be designated as a reject and removed from the dial.
- A fixed cam will divert completed assemblies to an eject chute equipped with a pneumatically operated box diverter.
- An air blow will remove rejects from the dial and blow them into a reject chute.
The machine is constructed with station tooling mounted to a ground steel top plate supported by a fabricated steel base. Mechanical drive, pneumatics, and electrical equipment are all hard mounted to the base. Machine components are black oxide, anodized, plated, or painted as necessary. All painted components will be painted with an oil base machinery enamel. Perimeter guarding consists of polycarbonate panels that protects your employees from pinch points and rotating areas.
