About This Product

■Product Overview

In recent years, machining has demanded working accuracy on the order of microns and submicrons. To maintain such high accuracy, thermal displacement caused by heat from rotating bodies and other sources must be eliminated in addition to mechanical adjustment. Precise Fluid LT is a high-performance temperature control medium for machine tools that answers these needs and is also designed for use in cold climates. Features

■No Risk of Fire

Precise Fluid LT is based on a water-soluble base material and water and exhibits no flash point, so it is handled as a non-hazardous material under the Fire Service Act. Heating and cooling may take place automatically and unattended when work begins at the start of a shift or during nighttime operation, but Precise Fluid LT poses no fire risk and can be used with confidence.

■Excellent Heat Transfer Characteristics

Because Precise Fluid LT is based on a water-soluble base material and water, it has approximately twice the specific heat and approximately four times the thermal conductivity of conventional mineral-based heat transfer oils, giving it high heating and cooling performance. Warm-up operation time can therefore be shortened, and the machining accuracy of the machine tool in operation is kept consistently high, enabling the production of high-value-added products.

■Excellent Corrosion and Rust Prevention

When water itself is used as the heating and cooling medium, corrosion can reduce heat transfer performance and lead to clogging of piping. Precise Fluid LT prevents corrosion of ferrous and copper-based metals through the addition of carefully selected corrosion inhibitors. The addition of a vapor-phase rust inhibitor also prevents rust on tank ceilings and in piping while the machine is held in inventory after shipment.

■Excellent Pumpability and Lubricity

To circulate the heating and cooling medium efficiently and prevent abnormal wear of the circulation pump, a certain level of viscosity and wear protection is required. Precise Fluid LT offers excellent pumpability and lubricity through the selection of an appropriate viscosity and the action of an anti-wear additive.

■Usable in Cold Climates

With a freezing temperature of -19°C, it can be used in plants in cold regions.

■In-Service Fluid Management

Precise Fluid LT contains water, so it may evaporate with use and cause the viscosity to rise. Depletion of the vapor-phase rust inhibitor may also lead to corrosion and rust problems. In-service fluid management is extremely important for safe operation of the equipment.
