When buying a Sardick AD30LS machine, how do I determine how new or old the equipment is?

When purchasing a Shadick AD30LS machine tool, judging the newness of the equipment needs to be assessed comprehensively from multiple dimensions such as **usage records, physical condition, and functional performance**. The following are specific methods:

1. Verification of equipment use records

Production date and service life:

Check the production date through the body nameplate or serial number of the equipment, combined with the use of time provided by the seller (such as ‘factory in 2020, the cumulative working hours of 5,000 hours’) to determine the degree of aging. Usually the design life of EDM machines is about 8-10 years, and long-term high-load use may accelerate the wear and tear.

Hours of operation statistics:

  Check the operation log or counter in the control system to confirm the actual machining hours. If the machine is frequently used for high-precision machining (e.g., mould making), there may be hidden wear and tear on key components (e.g., guideways, electrodes) even if the hours are short.

2. Appearance and Physical Condition Inspection

Wear and corrosion of the machine body:

Observe whether there are scratches, dents or rust on the worktable surface, guide rails, screws and other key parts. If there are obvious oil sludge or wear marks on the surface of the guide rail, it may affect the machining accuracy.

Cables and interfaces:

Check whether the cables and plugs are aged or loose, and whether there are traces of oxidation or ablation at the interface (which may be caused by abnormal discharge).

Working fluid system:  

  Check whether the oil tank and piping are clean, and whether there are signs of leakage or blockage. Equipment that has not been maintained for a long time may corrode internal parts due to coolant contamination.

3. Function and Performance Testing

Trial machining verification:

Require the seller to process standard parts (e.g., test electrodes) on-site, and observe whether the processing accuracy (e.g., dimensional consistency, surface roughness) is in line with the nominal parameters of the equipment (e.g., Ra ≤ 0.1μm).

Axis motion test:  

Manually operate the movement of each axis (X/Y/Z-axis) to check whether there is any jamming, abnormal noise or positioning deviation. Linear motor-driven AD30LS should be highly responsive, if it moves sluggishly there may be a drive system failure.

Discharge stability test: 

  Run the discharge programme and observe whether the spark is even and stable. If abnormal discharges (e.g., arcing, short circuits) occur frequently, it may be an indication of an aging power supply or control system.

4. Maintenance and Repair History

Maintenance records:

Complete maintenance records are required, including the frequency of spindle lubrication, guideway cleaning, and cartridge replacement. Equipment that has not been maintained for a long period of time has a higher failure rate.

Overhaul Records:  

Confirm whether the equipment has undergone overhaul (e.g., replacement of spindles and guide rails), and equipment after overhaul requires special attention to the life and compatibility of maintenance parts.

5. Accessory and control system assessment

Accessory Integrity:

Check whether the standard accessories (e.g. electrode clamps, working fluid circulation system) are complete, and whether the optional functions (e.g. automatic electrode changer) are functioning properly.

Control System Version:  

The ProCon system on the AD30LS needs to be checked for software version; outdated versions may lack the latest machining strategies or have compatibility issues.

Software and Parameters:  

  Check whether the user programme can be called up normally and whether the parameter settings are consistent with the factory standard (e.g. discharge energy, tool lift frequency).

6. Certification and Documentation Verification

Origin and Compliance:

Imported equipment is required to provide proof of origin, import customs declaration and China safety certification (e.g. CE certification) to avoid purchasing illegal channels or modified equipment.

Warranty & Service: 

  If the equipment is still under warranty, you need to confirm whether the warranty terms are transferable to the new buyer.

7. Price and Market Comparison

Refer to the market price: 

Compare the market price of used equipment of the same model (e.g. a brand new AD30LS is about $400,000 - $500,000, used equipment is usually between $8,000 and $200,000). Too low a price (e.g. ‘$888’) may be incomplete or seriously faulty.

Bargaining room: 

  Bargain reasonably based on the condition of the equipment, the completeness of the accessories and the seller's eagerness to get rid of it, and ask for an extended warranty or free maintenance clause if necessary.

Summary advice:

Give priority to formal channels: Reduce the risk of fraud by trading through Shadiq certified second-hand dealers or platforms with good reputation in the industry.

Professional machine inspection: Hire experienced technicians or third-party testing organisations to conduct a comprehensive assessment of the equipment, focusing on precision, spindle runout and discharge stability.

Clear terms in the contract: state the status of the equipment, warranty responsibility and liability for breach of contract in the contract, and ask for a 3-6 month trial period if necessary.

Through the above methods, you can effectively judge the degree of newness of Sardick AD30LS and avoid production loss due to hidden defects of the equipment.
