Enhancing Efficiency: The Transformation of a Stamping Plant’s CNC Machine

Computer Numerical Control (CNC) machines are a critical asset in any stamping plant. They are responsible for handling a range of precise or complex machinery. When these machines break down, it can result in costly, time-consuming repairs that prevent the facility from operating effectively. Martin Supply was approached by a manufacturer who had severe problems with their CNC machine and, consequently, suffered significant losses. Martin’s industry experts began to investigate and find the root of the issue.

Identifying Key Challenges

The CNC machine required lengthy 4-day downtimes for heat treatment. It also had issues with foaming, which reduced visibility and increased cycle time. The CNC machine’s prolonged downtime and foaming complications significantly hindered operations. These repeating issues resulted in substantial costs during each downtime occurrence and would consistently halt production.

Strategic Intervention by Martin Supply

With so many issues in such a high-value machine, the Martin Team took great care to make sure each problem was taken care of thoroughly. Through their investigation, they discovered that the issues may stem from the coolant that was being used. After reviewing several options, they decided to change to a high performing, semi-synthetic coolant with multi-metal capabilities. The product was designed provide optimal tool life and surface finish while reducing foam in de-ionized water.

Getting Results

Changing the coolant resulted in a substantial reduction in downtime from 4 days to 2, which produces a cost saving of $2,000 per instance. The foaming issues were also reduced, greatly improving visibility during production. Cycle time was also improved from 12 to 6 minutes, accompanied by a 40% acceleration in machine performance. The change in coolant also improved tool life, cutting precision, and tapping capabilities. Overall, these changes translate into an annual cost saving of $360,000.

This example shows the value of bringing Martin to your facility and how changing one part of your process can lead to large gains. The selection of an appropriate coolant not only mitigated downtime and foaming concerns, but also improved the facility’s entire production process.
