1) Machine Overview

The BACA Systems Robo SawJet V2.0 is a next-generation robotic stone cutting and waterjet system combining 6-axis robotic motion with high-pressure waterjet and diamond blade cutting.
Built in the USA, it is engineered for high-throughput countertop and slab fabrication, integrating FANUC robotic precision, KMT or Hypertherm waterjet technology, and BACA’s proprietary software suite for nesting, optimization, and automated loading/unloading.

The Robo SawJet V2.0 eliminates multiple manual setups—cutting straight lines, arcs, and sink openings in one continuous cycle with unmatched speed and repeatability.

3) Structural Integrity & Mechanical Health

• Robot Arm:
  Inspect each axis joint (J1–J6) for smooth motion, absence of play, and consistent servo load readings.
  Look for cracks on the cast arms or base pedestal due to transport or collision.
• Cutting Head Assembly:
  Check the saw spindle bearings, blade flange face, and nozzle holder alignment.
  Inspect the air/oil lines to the blade guard and waterjet hoses for leaks or stiffness.
• Bridge / Frame / Table:
  Confirm table flatness with a precision straightedge (tolerance ≤ 0.3 mm over 2 m).
  Inspect welds, frame alignment, and rust, especially on machines stored outdoors.

6) Electrical, Pneumatic & Control System Checks

• Control Panel:
  Open and inspect wiring harnesses for corrosion or rodent damage.
  Ensure cooling fans, relays, and emergency stops are functional.
• Robot Controller (FANUC):
  Power on and check for alarm-free boot.
  Verify software version (≥ V8.xx) and license keys for BACA RoboMotion or RoboCut.
• HMI Interface:
  Confirm touchscreen calibration, job queue display, and network connectivity.
• Pneumatic Circuits:
  Check solenoid valve banks for air leaks; test tool-change air blowoff and vacuum valves.
• Vacuum System:
  Inspect pumps, vacuum cups, and lines; check for air leaks with a pressure decay test.

7) On-Site Inspection Procedure

A. Static Evaluation

1. Inspect the robot pedestal and mounting bolts.
2. Verify all guard sensors and light curtains function correctly.
3. Check electrical cabinet humidity and grounding continuity.
4. Confirm waterjet filter and pressure gauges are readable and functional.

B. Power-On Test

1. Home all robot joints; check for smooth motion and repeatable origin return.
2. Run a dry cycle simulating saw-to-waterjet transitions.
3. Operate vacuum tables; verify clamping pressure stability.
4. Start high-pressure pump at idle—listen for pulsing or air in system.
5. Run test cut: straight line + radius + sink opening.

C. Cut Evaluation

• Measure edge straightness (≤ ±0.25 mm).
• Evaluate cutting kerf smoothness under magnifier—no chipping or gouging.
• Inspect transition zone between saw and waterjet paths for alignment precision.

8) Common Wear & Failure Indicators

• Robot Cable Harness Stiffness: Indicates cable fatigue inside dress pack.
• Saw Spindle Bearing Noise: Rattling or grinding sound at ramp-down.
• Waterjet Pump Seal Leakage: Moisture at pump head or pressure loss over time.
• Vacuum Table Air Leaks: Weak slab retention or inconsistent suction.
• Faulty Servo Drives: Repeated FANUC servo error codes (SRVO-021, SRVO-038).
• Corroded Electrical Contacts: Caused by humidity or improper storage.
• Blade Guard Crack or Deflection: Visual wear; unsafe to operate.

Pro Tip

A high-quality BACA Robo SawJet V2.0 should demonstrate consistent cut accuracy, smooth tool switching, and stable high-pressure output without leaks or noise.
Always request a live cutting demo and verify that both saw and waterjet paths are aligned within tolerance across the slab surface.
Units with recent pump rebuilds, FANUC controller updates, and active BACA service contracts command premium resale value.
