WHAT TYPE OF COOLANT IS RECOMMENDED FOR USE ON HURCO MACHINE TOOLS  

This article applies to:
Hurco Products 
Machining Centers 

Answer:
In selecting a coolant to be used in a Hurco Machine Tool the Coolant should have these qualities:
Suitable for the workpiece material and machining operation
soluable in water and having good mixing properties
mineral oil content of at least 35%. (synthetic coolants and coolants that contain too little mineral oil will gum the slideways when in contact with the slideway lube oil)
no aggressive additives; however, suitable additives can increase cutting capacity
adequate rust protection at proper concentration
anti-form, anti-bacteria and anti-fungi agents
no skin irritation when prepared to manufacturer's specifications
penetrating lubrication oil or "leak oil" should float on the surface of the coolant (instead of dissolving into the coolant)
Hurco recommends to use a non-synthetic water soluble oil, such as HOCUT 795 H or equivalent to prevent damage to the machine tools slideways, precision ballscrews and the painted surfaces. HOCUT 795 is offered by Houghton International, Inc. Can be found on the web www.houghtonintl.com.
Failure of devices or performance problems related to the coolant are not a defect in Hurco's material or workmanship, and will not be covered by Hurco's warranty.
