Indexing dial multiple-piece assembly machines provide dwell time which allows for multiple, complex operations to be performed accurately and typically at a lower cost than continuous motion machines. Central Machines is experienced with creating indexing assembly machines that can perform operations such as assembly, testing, inspection, heat staking, ultrasonic welding, and flash trimming during this important dwell time. Operations such as electrical connector and component assembly, as well as other assemblies from ink jets to baby bottles, can all be performed on our multiple piece assembly machines.
Another advantage of these machines is their functional flexibility. They can assemble and perform operations on parts that would be too large for continuous motion machines. Once our design team determines your production needs, we will recommend the best solution to fit your functional and financial criteria. Because each customer is different, we offer a long list of options from inline vibratory or centrifugal feeders to defective part sensors to multiple machine integration.
From each and every machine, our customers can expect longevity and reliability due to our 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.
Our machines are user-friendly and programmable. A color display touch screen panel is the primary user interface. Using the touch screen, the equipment can be programmed to run different jobs. Operators need only to enter a part number into the touch screen, and the machine will access its local database to start producing the part.
We performance-test, debug, and install all the equipment that we build. Our skilled personnel provide phone support, on-site maintenance, and servicing support. Lastly, we provide training on equipment installation and usage.

General Machine Description
The Indexing Dial multiple piece assembly machines are based on Central Machines’ standard dial-indexing platform with cam-driven pick & place units mounted in board of the assembly dial to provide good accessibility to the individual stations.The machines include the following standard features:
- A Precision Indexer with precision stops will drive the tooling dial plate.
- Piece part fixtures mounted to the indexing dial plate will transport product between stations.
- Feeder bowls to orient product.
- In-feed tracks to transfer the product to the pick and place escapements.
- Precision cam driven pick and place devices that transfer product from the escapements to the fixture nest.
- Off load conveyor to transfer assemblies to a two position box diverter.
- Fixture tracking system will monitor good and bad parts through the system.
- Touch screen operator interface with message display.
- Mechanical and Electrical operating manuals.
Each station is mounted on identical station plates for added flexibility, and is constructed with tooling mounted to a ground steel top plate supported by a fabricated steel base. Mechanical, pneumatic and electrical equipment are group mounted on the base. Electrical controls are mounted in NEMA 12 style enclosures and all tooling will be hardened and ground. Machine components can be anodized, plated, or painted as necessary. Pinch points and rotating sections will be guarded to prevent operator injury. Perimeter guarding is electrically interlocked and fabricated with clear polycarbonate panels and extruded aluminum.
