Problems related to cast iron machining mostly result from machined graphite dust and CI chips.  Even today we are struggling to find a reliable and effective way to filter cast-iron chips and fines.  Cast-iron fines are notoriously hard to remove, requiring manufacturers to use vacuum filters or replaceable media to try to extend metalworking fluid life and prevent fines from circulating back to the machine.  Vacuum filters are more expensive than gravity bed.

Chip wringing can be exhausting.  Especially for the small machin shop owner.  Fortunately, the technology for this process has been successfully captured for years.  There are several competing processes, including those that crush the chips into little hockey pucks for handling and recycling. 

Here's another great opportunity to enhance your metalworking fluid education.  The STLE Emulsifier series will be presented by Jennifer Ineman and Joe Schultz. This first presentation will cover the basics of what an emulsion is, what chemistries and which fluid types are typically used in metalworking applications, what the hydrophilic-lipophilic balance is and why it is important to emulsifier selection.

After successful event of IMTEX2013 in Banglore earlier this year, the Indian Machine Tool Manufacturers have organized MODERN MACHINE SHOP 2013.  This is an international exhibition of manufacturing technology and production equipment in three major Industrial hubs of India; New Delhi, Mumbai and Chennai.  A one-stop-shop for engineering industry in its third edition, this will be the ultimate destination to demonstrate potential and futuristic technologies in the field of metalworking ma

You don't have to love their logo to be interested in working at Quaker.  Here is a great opportunity for you to go to work for perhaps the best known metalworking fluid supplier on the planet.  Quaker is looking for a Metalworking Fluids Regional Product Manager at PA-Conshohocken (Headquarters).

Mark your calendar now ofr you know you will miss this.  Join STLE for this important webinar, featuring instructor John Burke (Houghton International) who will discuss waste water treatment for metalworking fluids.  Cost: $39 for members, $59 for non-members.  Credit may be applied to recertification.

Here comes one more cyclone from ZYKLOMAT, designed for cleaning aqueous fluids up to 5 microns.  If you want a desired throughput there is a possibility of combining number of individual ZYKLOMAT® hydrocyclones to form lengthwise or round distributor units.

We cherish too, the Poppy red
That grows on fields where valor led,
It seems to signal to the skies
That blood of heroes never dies

Traditional honing and lapping operations have taken on a new dimension of accuracy and precision. In double wheel lapping, the abrasive wheels far exceed the 0.0002- to 0.0003-inch tolerances of conventional grinders, and it takes that 0.025 inch of carbide stock off both sides simultaneously within 4 to 5 minutes. It means a highly efficient filtration system is required to keep dissolved solids out of the system.

FILTRATION MONTH would not be complete without discussion of the Hydrocyclone, whose power through Nature is well-known.  Hydrocyclones are used to separate solids from Metalworking Fluids using centrifugal force. No disposable filter media is required in the cyclonic separation process making hydrocyclones economical, efficient and environmentally responsible.
