Preserving Equipment Integrity

Punching machines, along with their associated equipment like feeding and leveling machines, endure rigorous operations day in and day out. Despite the constant movement of internal transmission components such as rollers and sliding seats, these parts manage to maintain their durability over time. This begs the question: What prevents rapid wear and tear? Additionally, the size of large three-in-one feeding machines presents a challenge for shipping, often requiring packaging in wooden boxes to withstand exposure to rainwater. How do they withstand such elements? Apart from meticulous lubrication and rust prevention, the answer lies in the protective plating and coating of surrounding equipment.

The Role of Thickness

The effectiveness of plating and coating hinges largely on their thickness. Thin layers are prone to quick deterioration or corrosion. So, how do punching machine equipment, like feeding and leveling machines, ensure the thickness of plating and coating meets industry standards? Precise measurements are crucial, facilitated by the use of a film thickness gauge.

Introducing the Japanese Kett LZ-370

Our tool of choice for precise measurements is the Japanese Kett dual-function film thickness gauge LZ-370. Comprising the main unit, electromagnetic head, ferrous metal substrate, eddy current head, non-ferrous metal substrate, and various film thickness standard specimens, this gauge provides accurate readings essential for quality control.

Measuring Principles

Electromagnetic Measuring Head

Designed for non-magnetic coatings on magnetic metals, this head utilizes an AC electromagnetic coil. As the coil interacts with the metal surface, changes in magnetic fluxes result in voltage variations, which are then translated into coating thickness. This method is ideal for assessing paint film thickness on machine bodies and chromium plating on critical components like rollers and bearings.

Eddy Current Measuring Head

For non-magnetic coatings on non-magnetic metals, such as anodized films on aluminum alloy or coatings on stainless steel, the eddy current measuring head is employed. By inducing eddy currents on the metal surface, changes in voltage across the induction coil allow for precise measurements of coating thickness.

Importance of Precision

While the naked eye or conventional tools may fail to detect subtle differences in coating thickness, the ramifications of inadequate protection can be significant. To uphold product quality and durability, meticulous control over plating and coating thickness is essential. Utilizing a film thickness gauge ensures optimal rust prevention and wear resistance, underscoring our commitment to delivering high-quality equipment to our valued customers.
