SDChassis Machine Technology
The SDChassis is a proprietary, world-class, pre-engineered, high-speed assembly platform.
Constructed of heavy steel and precision components, the SDChassis 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. It’s function also extends to processing, pick-and-place and probing actions. With over 20 years of production, the SDChassis machine platform has proven to be a high-quality and cost-effective choice compared to similar, fully customized options.

SDChassis – How it Works
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. 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 self-governing 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.
Unparalleled CAM-Driven Motion
The SDChassis’ heavy rugged, pre-engineered base provides smooth, high-speed electro-synchronous CAM-driven motions (machine speed can be adjusted and all stations stay synchronized). Pre-engineered probe/verify modules provide a smooth vertical or horizontal motion generated by the reciprocating hubs of the SDChassis. Each module is tooled with a probe containing soft springs for gentle part contact while electric sensors, such as an optical sensor, provide a rugged yet precise method for verifying both part presence and position.
Pre-engineered pick-and-place motion modules provide a smooth, high-speed automated system with motion generated by the reciprocating hubs of the SDChassis. Each pick-and-place module is custom tooled to handle a specific part (like a pneumatic gripper, suction cup, etc.).
A servo-driven indexing dial with a high degree of positional repeatability offers table fixtures custom tooled specifically for your parts. An encoder is used to electronically synchronize the indexing motion to the main SDChassis CAM and a shot-in is engaged at every dwell to ensure positional accuracy. Pre-engineered motion and head tracking software is integrated with the PLC control system.
Custom Tooling
We have a library of pre-engineered motion modules for the SDChassis. This allows 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.

Case Study:
Wire Inserting and Forming Assembly Machine
SDC designed and built an indexing dial assembly and test machine to manufacture a secondary bobbin assembly. This system was built on the SDChassis machine platform and provided a pre-engineered, smooth-running and cam-driven machine platform.
