Key Purchasing Considerations for Used Automation Equipment
- Compatibility: Ensure the component (e.g., a PLC or drive) is compatible with your existing systems, network protocols (e.g., Profinet, EtherNet/IP), and programming software.
- Operating Hours: For robots and mechanical parts, check the total operating hours to estimate remaining service life and potential maintenance needs.
- Firmware and Software Version: Verify the firmware version of PLCs and drives, as this can affect compatibility and feature availability. Ensure any required software licenses are included or available.
Frequently Asked Questions About Industrial Automation
What is a PLC (Programmable Logic Controller)?
A PLC is a ruggedized industrial computer used to automate manufacturing processes. It reads inputs from sensors and switches, executes a user-written program, and controls outputs like motors, valves, and lights. PLCs are the "brains" behind most modern automated machinery.
What is the difference between a PLC and a PC?
While both are computers, PLCs are specifically designed for the harsh industrial environment, with robust hardware and a real-time operating system for reliable, deterministic control. PCs are designed for general-purpose computing and are not typically used for direct machine control in critical applications.
FAQ
How do I find the right spare part using a Siemens part number?
Siemens part numbers follow a specific format: 6ES7 XXX-XXXX-XAXX for S7-300/400 PLCs. The first digits indicate the product family, subsequent digits specify the exact module. To find parts: 1) Use the exact order number from the module label, 2) Check Siemens Industry Mall for cross-references, 3) Look for -0AB0 vs -0AA0 suffix differences (revision levels), 4) On WeSellMachines, search by the full 6ES7 number. Always verify voltage and firmware compatibility.
What should I check when buying used industrial machinery?
Key inspection points: 1) Operating hours and maintenance records, 2) Physical condition - wear, rust, damage, 3) Electrical systems and controls, 4) Hydraulic systems - check for leaks, 5) Safety features and CE compliance, 6) Test run under load, 7) Spare parts availability, 8) Original documentation.
What should I check when buying a used industrial robot?
Key inspection points for used robots: 1) Controller condition and software version, 2) Robot hours - spindle hours and power-on hours, 3) Joint play - manually check each axis, 4) Cable dress pack condition, 5) Absolute encoder batteries and calibration, 6) Teach pendant functionality, 7) Safety circuits and emergency stop, 8) Original documentation and backup programs. Request a full cycle test to verify accuracy and repeatability. Popular brands: Fanuc, KUKA, ABB, Yaskawa.
What is the typical depreciation rate for industrial machinery?
Industrial machinery typically depreciates 15-20% in the first year, then 8-12% annually. After 5 years expect 50-60% depreciation. After 10 years, machines retain 25-40% of original value. Premium brands hold value better.
Are used PLC modules reliable for production use?
Yes, used PLC modules can be highly reliable if properly tested. Industrial PLCs like Siemens S7 and Allen-Bradley are designed for 10-20+ years of operation. Key considerations: 1) Purchase from reputable sellers with testing capabilities, 2) Verify firmware compatibility with your existing system, 3) Check for end-of-life status - older modules may lack support, 4) Request functional testing certification, 5) Have backup modules for critical systems. Used PLCs typically cost 40-70% less than new.
What is the difference between CNC and conventional machines?
CNC machines are computer-controlled offering precise, repeatable operations. Conventional machines require manual operation. CNC advantages: higher precision, faster production, complex geometries. Conventional advantages: lower cost, simpler maintenance, better for one-off jobs.
What payment methods are safe for international machinery purchases?
Safe methods: 1) Letter of Credit - bank guarantees both parties, 2) Escrow services - funds released after inspection, 3) Partial payment with inspection clause - 30% deposit, 70% after inspection. Avoid full wire transfers before inspection.
How do I check operating hours on used machinery?
Location varies by control: Fanuc - PMC diagnostic screen, Siemens 840D - Diagnostics menu, Mazak - Maintenance screen. For construction equipment check dashboard hour meter. Always verify with service records.
