The SDChassis is a proprietary, world-class, pre-engineered high-speed assembly platform, offering extremely flexible tooling options and servo indexing table arrangements. Constructed of heavy structural steel and robust precision components, the SDChassis, at its core, creates synchronized motion for all common automation processes.

With a fast and flexible small part assembly and processing machine center, a custom-tooled SDChassis is the perfect solution for any machine that requires high-speed, small-part assembly or processing and pick-and-place and probing actions. With over 16 years of production, the SDChassis machine platform has proven to be one of the most robust and cost-effective choice compared to similar fully customized options.


The SDChassis combines accurate and smooth tooling motions from its large CAM, along with the flexibility and programmability of a servo-driven indexing table and plate CAM encoder. The servo-driven indexing table allows for parts fixturing ranging from 4 to 48 stations, and the synchronized Servo CAM drives reciprocating plates that provide the motion for the tooling.

Two upper and one lower reciprocating hubs are driven by three independent telescoping center shafts that each travel on independent CAM tracks. As the CAM turns, it generates independent vertical motion for each hub. The hubs include precision linear bearing and ride-on precision ground shafts. The vertical reciprocating hub motion is then available for SDChassis motion tooling.


We have a library of pre-engineered motion modules for the SDChassis, allowing users to achieve virtually any assembly operation, including pick-and-place, light press, vertical and horizontal slides, probing, escapement, and many other motions. Additionally, standard tooling can be customized, or new tooling can be designed and built for your specific application. SDC’s expertise in designing custom parts fixtures specifically for the SDChassis allows us to offer fixtures for virtually any part.

At SDC, we specialize in custom engineering and design. We’ll work with you on every SDChassis to deliver a complete custom assembly and/or processing machine.


Common SDChassis automation cells include:

Robotic parts loading and/or unloading (picking from a pallet or an array)

Vibratory parts feeding

In-feed and out-feed conveyors

Many other parts feeding systems, including manually loaded in-feed conveyors
