Micro Studio PMZ 900N
The PMZ 900N is an advanced load scale that offers numerous benefits to those in the spring industry. Its automation allows for efficient testing of compression springs up to 19 inches long and 2 inches in diameter, and extension springs with a stroke up to 20 inches, making it a highly versatile and adaptable tool. It has a maximum load capacity is 200 pounds. Its software enables the user to save part number specific test programs, increasing efficiency and ease of use. The scale can also operate like a traditional manual load tester, offering greater flexibility to the user.
One real-life example of the PMZ 900N in use is compressing a 1-inch long conical compression spring five times to 0.400 inches before testing, ensuring that it does not lose more than 0.010 inches in length after set. The PMZ 900N can measure the spring’s free length, move to set the spring at 0.400 inches 5 times, and measure the free length after it is set. Next, the scale will make one smooth stroke movement down to 0.390 inches and display the load readings for 0.900, 0.700, 0.500, and 0.400 inches, as well as the rate between the first and last loads. The test takes approximately 18 seconds to complete.
The PMZ 900N can be connected to Micro Studio LED 3D, enabling the tests taken by the PMZ 900N to utilize functions of the LED 3D such as concentricity or parallelism measurements at any point during the testing program. Both the PMZ 900N and LED 3D allow the operator to record test results for analysis and capability testing. Results can also be saved within the software or as reports in the form of PDF or spreadsheet.
It is important to note that the PMZ 900N has some limitations, including difficulty testing long narrow springs and springs that have loads outside of its operating range. In these cases, manual load scales are used instead.
In conclusion, the PMZ 900N is a powerful tool that can improve efficiency, accuracy, and overall quality control in the spring industry. Its automation, software capabilities, and ability to connect with the LED 3D make it a valuable investment for companies dedicated to providing high-quality products and exceptional customer satisfaction.
Micro Studio LED 3D
The Micro Studio LED 3D is a sophisticated image measurement system (IMS) that is specifically designed for cylindrical and conical compression springs that are up to 3.5 inches long and 2.5 inches in diameter. The LED 3D operates on a dedicated version of the software used by the PMZ 900N, and as such, it has all of the same test program customization and test result storage and presentation. In fact, the LED 3D is most effective when used in tandem with the PMZ 900N to create a detailed set of measurements.
The LED 3D also has a manual mode, which allows users to place a spring onto its rotating platter and instantly view free length, squareness, and parallelism results. For example, in the case of the conical compression spring from the PMZ 900N, assuming that the part takes a significant set, the LED 3D can be used to measure the concentricity of the part before and after the five compressions to ensure that the spring stays centered even after set. This requires moving the part from one scale to the other in-between steps, and the results are saved to the same report.
Moreover, the LED 3D can be used as a valuable troubleshooting tool for machine operators when setting up conical springs. The IMS can rotate the platter on which the spring is placed, count the number of coils, and track the diameter along the entire body of the spring. The results are then displayed on a graph, allowing the operator to see the taper of the spring. Taper is a crucial factor that calipers cannot measure, and it can impact any load or rate measurements. Therefore, being able to measure the taper removes the need for the ‘guess and check’ method and speeds up the setup process.
Keyence IM-6500
The Keyence IM-6500 is a powerful and versatile image measurement system (IMS) that offers a wide range of measurement tools. This IMS is designed to measure lengths, radiuses, angles, parallelism, and other dimensions of varying complexities. It is particularly useful for measuring wire forms, torsion springs, and springs with legs, hooks, or other features.
One of the key advantages of the IM-6500 is that it can almost completely replace the need for a traditional optical comparator. With its point-and-click measurement operation, this IMS drastically reduces inspection time compared to an optical comparator. This makes it an ideal tool for quality control and inspection applications.
In addition to its speed and accuracy, the IM-6500 offers the ability to program predetermined measurements for specific parts. This allows machine operators to utilize the IMS as part of their production control and monitoring processes. This feature can greatly increase efficiency and productivity in manufacturing environments.
For small parts or details that require high precision measurements, the IM-6500 features a high precision mode. This mode allows for extremely accurate measurements of even the smallest details. Additionally, the IM-6500 features a powerful LED light source that can illuminate features on surfaces that may not be visible on an optical comparator. This can be particularly useful for measuring parts with complex geometries or intricate features.
Overall, the Keyence IM-6500 is a powerful and versatile IMS that can greatly improve efficiency and accuracy in quality control and inspection processes. Its wide range of measurement tools, programmable features, and high precision capabilities make it an essential tool for manufacturing environments.
Manually Operated Load Scales
The PMZ 900N, while a highly capable image measurement system, has some limitations when it comes to certain types of springs. For long, narrow springs and those with loads outside of the PMZ 900N’s operating range, we turn to manual load scales.
Our three go-to manual load scales are the Carlson 600 Gram, Chatillon DST 40, and Larson CDHT 750. All three are manufactured by trusted names in spring testing and have proven their accuracy over many years. These scales are reliable, user-friendly, and require minimal training to operate effectively.
The Carlson 600 Gram is specifically designed for small, light wire parts that require a more sensitive load scale than the PMZ 900N. It can measure springs up to 1.3 inches long and 1.3 inches in diameter, with a limit of 1.3 pounds. It is typically used for springs with loads below 0.100 pounds.
At the opposite end of the spectrum, we have the Larson CDHT 750, which has a maximum load of 750 pounds. This scale is perfect for strong compression springs with relatively heavy wire up to 5.8 inches long and 2 inches wide. For springs up to 3.8 inches wide, we have custom fabricated plates to accommodate them. This scale is used for any springs that require loads above 200 pounds.
Finally, the Chatillon DST 40 is a versatile scale that can be used for most compression and extension springs with loads up to 40 pounds. It boasts a wide 4-inch plate and an 8.2 inch stroke, and features holes in the upper plate that allow the operator to slide springs onto support pins of different diameters. This is crucial for long, narrow springs, which tend to buckle when compressed. By using support pins inside the spring, the operator can ensure that the spring exerts force vertically and obtain an accurate reading.
Overall, our selection of manual load scales provides a comprehensive solution for measuring a wide variety of springs, including those that fall outside the PMZ 900N’s capabilities.
