An important question we often get asked by our customers around the world is how to inspect used press machinery.  If you are planning to buy fully functional used Japanese press machinery from Japan, there are a few things you need to consider before actually buying the said machinery from Japan.  If you would like to purchase the used press machinery from us, our engineers will thoroughly inspect the machine before shipping it to you.

Used press machines offer a cost-effective solution for many businesses. They provide the same functionality as new machines but at a fraction of the cost, making them a popular choice for both small and large-scale operations. However, the efficiency and safety of these machines are heavily dependent on their condition, which is why the purchase of used press machines is often accompanied by a degree of risk.

This is where the significance of inspections for used press machines comes into play. Inspections serve as a vital step in mitigating the risks associated with buying and using pre-owned machinery. They help identify any potential issues, such as oil leaks, loose bolts, or inadequate oil levels, that could affect the machine’s performance or pose a safety hazard.

Moreover, regular inspections and maintenance of used press machines can extend their lifespan, ensure consistent performance, and prevent unexpected breakdowns. They also contribute to the safety of the workplace by ensuring that the machines meet all necessary safety standards.

In essence, while used press machines offer numerous benefits, their value can only be fully realized through thorough and regular inspections. This article aims to delve into the importance of these inspections, particularly focusing on used Japanese press machines, and provide a comprehensive guide on how to effectively carry out these inspections.

The Need for Inspecting Used Press Machines

Regular inspections of used press machines are not just a recommended practice; they are an absolute necessity in the manufacturing industry. These inspections are crucial for several reasons, primarily revolving around the themes of safety, efficiency, and longevity.

Firstly, safety is paramount in any industrial setting, and regular inspections are a key component in maintaining a safe working environment. Used press machines, if not properly inspected, can pose significant safety risks. These machines are complex and operate under high pressure, and any malfunction or failure can lead to serious accidents or injuries. Regular inspections help identify potential safety hazards, such as loose bolts, oil leaks, or faulty safety guards, allowing these issues to be addressed before they lead to accidents.

Secondly, the efficiency of a press machine directly impacts the productivity of a manufacturing operation. A machine that is not operating at its optimal capacity can slow down production, leading to delays and increased costs. Regular inspections ensure that the machine is in good working order and operating at its maximum efficiency. They allow for the early detection of issues that could hinder the machine’s performance, such as worn-out parts or inadequate oil levels, enabling timely repairs or adjustments.

Lastly, regular inspections contribute to the longevity of used press machines. By identifying and addressing issues early, inspections can prevent more serious damage to the machine over time. This not only extends the machine’s lifespan but also saves on the cost of major repairs or replacements.

On the other hand, the risks associated with not inspecting used press machines are significant. Without regular inspections, minor issues can go unnoticed and develop into major problems, leading to costly repairs, machine downtime, and even safety incidents. Furthermore, a machine that is not regularly inspected may not meet the necessary safety standards, which could result in regulatory penalties.

In conclusion, the need for inspecting used press machines cannot be overstated. Regular inspections are a critical practice that ensures the safety, efficiency, and longevity of these machines, ultimately contributing to a more productive and safer manufacturing operation.

We have listed the most important steps you need to take to inspect the used press machine you are planning to purchase.  These inspection steps are as follows.

How to Inspect a Used Press Machine

Inspecting a used press machine is a meticulous process that requires a keen eye for detail and a comprehensive understanding of the machine’s operation. Here is a step-by-step guide to help you navigate this process:

1. Visual Inspection: Start with a general visual inspection of the machine. Look for any obvious signs of damage or wear and tear. Check for oil leaks, loose bolts, and screws around the tooling area. Also, inspect the machine’s cleanliness, as a well-maintained machine is usually a good sign of its overall condition.

2. Check the Oil Levels: The oil level in a press machine is crucial for its operation. Ensure that the oil levels are correct and that the oil is clean. Dirty or low oil can indicate potential issues with the machine.

3. Inspect the Mechanical Operation: Turn on the machine and observe its operation. Listen for any unusual noises and watch for any irregular movements. These could be signs of underlying issues.

4. Safety Compliance: Check if the machine meets all the necessary safety standards. This includes inspecting safety guards, emergency stop buttons, and other safety features.

5. Test the Machine’s Performance: Finally, test the machine’s performance. Run a few cycles and observe if the machine is operating efficiently and accurately.

Special Focus on Inspecting Used Japanese Press Machines

Japanese press machines are renowned for their quality and durability. However, when inspecting a used Japanese press machine, there are a few additional factors to consider:

1. Manufacturer’s Guidelines: Japanese manufacturers often provide detailed inspection and maintenance guidelines. Make sure to obtain these guidelines and follow them during the inspection.

2. Spare Parts Availability: Check the availability of spare parts for the specific model you are inspecting. Japanese press machines often require specific parts, and their availability can significantly impact the machine’s maintenance cost and downtime.

3. Technical Support: Consider the availability of technical support for the machine. Having access to knowledgeable support can be invaluable, especially when dealing with complex machines.

In conclusion, inspecting a used press machine, whether it’s a Japanese model or not, is a critical step in ensuring its safety, efficiency, and longevity. By following these steps, you can make an informed decision and ensure that your investment is sound.

How To Inspect A Used Press Machinery?

  1. Interview the machinery operator or maintenance staff to know the basic info about the press machine, its past maintenance record, etc. The discussion may also reveal any past operating issues with the machine if any. Ask them specifically how would the machine be fully functional in a new environment such as your shop floor
  2. Check the control & electrical cabinet. This will help you understand how the machine works in a factory setting. Sometimes, the control & electrical cabinet of used Japanese machinery may not be easily understood due to the language barrier, etc.
  3. Carefully check the maintenance logs of the machine to find any serious issues in the past
  4. Verify the light curtains. Also, confirm whether the operator of the used press in question has stopped the press cycle properly
  5. Inspect whether the machine`s manufacturer plate is available.  Also, check its documentation to understand how it works most efficiently. In our case, the manuals will be in Japanese.
  6. Carefully check the stroke which is the length between the terminal points of the motion. Ideally, the length should be short enough for a speedy press machine
  7. Also, record die clearance, strokes per minute, length and width of the press machine bed, and the ram size
  8. Thoroughly inspect the press machine for any scratches, gouges, or cracks in the machine. Also, check for any painted areas the previous owner might have painted to cover up any serious damages.
  9. If possible, you should be able to turn the machine on to verify whether the machine’s ram can move up or down. Can it reach the very bottom or top of its track?  Does it give any strange sounds or gear grinding? Japanese Machinery can take a five-minute video of the press machine for you so that you know exactly how the press machine functions in a factory
  10. Perform a jack test to verify whether there are any internal problems in the ram or crown of the machine you are inspecting
