Good soluble cutting fluid for CNC Turning?

Good soluble cutting fluid for CNC Turning?

(OP)
Hi

I run a machine shop in England, UK and just wondered if anyone could recommend a good, stable soluble cutting fluid for machining steels and stainless steel upto 65mm diameter. We use a product at the moment that has a poor lifespan and want something we can re-use if possible.

We run Traub Fixed Head Machines, you can have a look at the link below for machine specs:

Thanks in advance

RE: Good soluble cutting fluid for CNC Turning?

i understand you use a emulsion at the moment ("soluble cutting fluid"). the lifespan of that type of product depends very much on operating conditions - the lifespan may be shortened quite a bit when dirt or trampoil is mixed with the cutting fluid.

what type of problems do you have? poor quality of machining, bacteria growth, darkening or unpleasant smell?

the first thing to look for is trying to improve operating conditions (cleanliness). if that is not possible you might consider a "synthetic" fluid, a concentrate that is soluble in water (and thus no emulsion).

have you already spoken with the supplier of the present fluid? most problems with machining fluids are due to less than perfect housekeeping or choosing a less suitable fluid for the material to be machined.

White Paper – Your Construction ERP RFP Checklist
Selecting business software for a medium to enterprise-sized construction concern is extremely challenging in large part because most enterprise resource planning (ERP) suites originated in the world of repetitive manufacturing and are therefore a poor fit for a project and asset-centric business. However, midsize to large contractors need the predictable, auditable processes that ERP delivers. Download Now
