What to Look for When Buying Used PAR Systems Equipment
PAR Systems builds 100% custom automation and manufacturing systems for demanding aerospace, nuclear, and defense environments. Each system is engineered to specific application requirements. Here is what to evaluate on used units.
On gantry robots and CNC trimming machines, verify all axes and spindle. Test gantry motion on all axes for smooth, accurate travel across the full work envelope. Check rack-and-pinion or ballscrew drives for backlash and positioning repeatability. On CNC trimming and milling systems, measure spindle runout, test automatic tool change function, and verify probe calibration. Check vacuum dust collection for proper suction at the cutting point. Test the CIMROC controller (if equipped) for clean power-up and program execution. On multi-axis systems (5-axis and above), verify simultaneous interpolation accuracy.
On friction stir welding machines, test the welding head and process control. Verify FSW spindle condition including runout, bearing condition, and torque delivery at rated parameters. Test the Z-axis force control system for maintaining consistent plunge depth and forge force during welding. Check the backing anvil or fixture for flatness and rigidity. Verify that the proprietary control system accurately monitors and records process parameters (spindle RPM, travel speed, forge force, temperature) and that weld quality data logging functions correctly.
On drilling and waterjet systems, check process-specific components. On drilling systems, test spindle speeds, feed rates, and hole positioning accuracy on sample material. Verify peck drilling cycles and chip evacuation. On waterjet systems, check the high-pressure pump for rated pressure and flow, inspect the cutting head and mixing tube for wear, and test XY positioning accuracy.
Evaluate the control system, safety, and integration. PAR systems often integrate multiple processes (cutting, drilling, inspection, handling) into a single cell. Test each process independently and verify coordinated operation. Check all safety systems including fencing, interlocks, light curtains, and emergency stops. Verify that communication interfaces between the PAR controller and any integrated equipment (robots, conveyors, inspection systems) function correctly.
PAR Systems XR Gantry Robots & CNC Trimming
The XR gantry robot series is PAR's core motion platform for large-envelope precision manufacturing. These Cartesian gantry systems provide multi-axis motion for CNC trimming, milling, drilling, scanning, coating, and non-destructive testing across work envelopes that can span entire aircraft fuselage sections. PAR's custom-built CNC milling and trimming machines integrate automatic tool changers, probe systems, vacuum dust collection, and inspection capability into purpose-built platforms for aerospace composite and metal processing. The proprietary CIMROC robot controller provides advanced motion control with real-time process monitoring. PAR's adaptive manufacturing technology uses sensor data to detect contour deviation and automatically adjust tool paths without human intervention.
PAR Systems Friction Stir Welding
PAR's friction stir welding machines represent the company's highest-growth capability area. FSW joins materials by generating frictional heat through a rotating tool pressed into the joint interface, producing high-strength solid-state welds without melting. PAR FSW machines handle applications ranging from small assemblies through entire aircraft frames. In one documented application, PAR's FSW gantry system welded a complete aircraft frame in 8 hours, replacing manual riveting that required 16,000+ hours. FSW technology serves space launch vehicle fabrication, commercial aviation structures, defense components, nuclear containment, and transportation applications.
PAR Systems Cranes, Marine & Nuclear
Through Ederer LLC (100+ years of specialty crane heritage), PAR designs and manufactures fuel handling cranes, outage-critical cranes, and remote handling systems for nuclear power plants and small modular reactors. Jered LLC provides military and naval marine equipment and cargo handling systems. PAR's nuclear capabilities include equipment for hot cell operations, process facilities, and decommissioning in Japan, the United Kingdom, and the United States. CAMotion provides advanced motion control and Cartesian palletizers. Oak River Technology serves automated manufacturing and medical device production.
