How to buy Used FEELER in China
1. Finding Reliable Channels (Information Gathering Phase)
Professional Used Equipment Dealers: In China, there are large used machine tool markets in areas like Foshan, Dongguan, and Jiangsu. Look for reputable dealers with physical showrooms in these areas. They typically offer a wide selection of models and basic warranty coverage.
Online B2B Platforms: Leverage platforms like "HUMADA" and others. Search for keywords like "Used FEELER" to identify suppliers with high credibility and positive customer reviews. Note: Platforms can be complex and require careful sifting.
Purchasing directly from end users: This is the ideal approach. Use industry contacts or equipment brokers to identify factories that are upgrading their equipment or have closed down. This "first-hand" source eliminates refurbishment or misrepresentation by middlemen, provides more transparent equipment history, and offers more competitive pricing.
II. Professional Machine Inspection and Value Assessment (Core Decision-Making Stage)
After finding the target equipment, a rigorous on-site inspection is essential:
Mechanical Inspection:
Precision Testing is Key: Use tools such as a dial indicator and laser interferometer to perform on-site inspections of the spindle's radial runout, end runout, and backlash of each linear axis. Accuracy data is the most crucial basis for negotiation.
Observe Wear: Check the X/Y/Z-axis guideways for scratches and wear, and inspect the ball screws for rust.
Test Spindle Performance: Run the spindle from low to high speed, listening for any abnormal noise and vibration. After shutting down, check for normal temperature rise.
In-Depth Inspection of Electrical and Control Systems:
Open the electrical cabinet: Check for internal cleanliness, oil, and dust. Inspect key electrical components (contactors, drivers, etc.) for signs of overheating or scorching. Verify that the CNC system (usually Fanuc) has no hidden alarms.
Functional Testing: Check all buttons, handwheels, lubrication, cooling, and other auxiliary functions for proper function.
"Test Cutting" Verification: Never rely solely on dry runs. Perform an on-site test cut of a test piece, including contours, bevels, and hole systems, using steel or aluminum, and immediately perform accuracy measurements. This is the sole criterion for verifying the machine tool's comprehensive dynamic accuracy.
III. Transaction and Follow-up (Final Execution Phase)
Negotiation and Contract: Use any issues discovered during the machine inspection as bargaining chips. The purchase contract should clearly specify the equipment model, serial number, current condition, included accessories (such as toolholders and fixtures), accuracy commitment, payment method, and delivery deadline.
Logistics and Installation: Ensure transportation is handled by a professional heavy equipment logistics company and that transportation insurance is purchased. Once the equipment arrives, arrange for an experienced technician to level the equipment, connect the power supply and air pressure, and conduct another accuracy check to ensure no damage was incurred during transportation.
