Milling Stainless Steel Without Coolant

Also if we review the chart of suitability at the top of the article assume you need to be nearer the top of the chart.

Milling stainless steel without coolant.

That s why you want to air blast coolant without fluid or oil. That was the case with this stavax 420 stainless steel mold core. Therefore dry machining is best suited to steel cast iron and some stainless steel. Small training or hobbies lathes and.

Mql and dry machining tips. High efficiency milling can be a very effective machining technique in stainless steels if the correct tools are selected. Stainless steel can be gummy enough that coolant may be needed as a lubricant when a ball nose or other round profile tool is used. So lets combine all these factors.

For stainless steel you ll want to use a coolant with a high oil content like straight oil since it has the stickiness associated with aluminum but with the hardness of steel. Dry turning is relatively rare for example compared to dry milling. With mist lubrication coolant volume drops to less than 50 ml hour compared to typical flood coolant volume exceeding 6 liter min. When dry milling wasn t producing an acceptable surface finish the operator switched to using liquid coolant and the finish improved.

Machines must be substantial and capable of making the deep cuts needed in machining austenitic stainless steel without slowing down the set feed or surface speeds. Helical solutions offers the hev 5 end mill which is an.
