The employees of a machine tool manufacturer prepare many different parts for an internal production order, which is very time-consuming. The customer has the pneumatic timer assembly manufactured by TRI-MATIC and thus reduces the internal workload.
In order to prolong the life of the machine, when the main switch of the machine is turned off without available power, a one-hour overpressure is required on all pneumatic components. This prevents the coolant consisting of water and oil from entering the pneumatic elements when the machine is switched off.
An accumulator with a calibrated leak was used for time counting. Since the accumulator is empty after exactly one hour, the valve interrupts the machine's pneumatic circuit, which keeps the components under pressure. The air in the accumulator is only used for time counting, but not to keep the components of the machine under pressure.
The customer and TRI-MATIC engineering have together developed a pneumatic timer that meets the customer's requirements. TRI-MATIC's assembly department now creates a set composed of the air reservoir and the small parts, which are packed and delivered in a plastic bag and a separate cardboard box.
