THIS IS A SOUTH BAY TECHNOLOGY MODEL 850 WIRE SAW.THE MODEL 850 IS PRIMARILY USED FOR CUTTING VERY FRAGILE MATERIALS, SUCH AS INTERMETALLIC CRYSTALS OR SUBSTRATES WITH DELICATE LAYERS, THAT WOULD FRACTURE OR CHIP USING OTHER METHODS OF SLICING. HOWEVER, IT CAN BE USED TO SLICE VIRTUALLY ANY MATERIAL, WHICH MAKES IT AN EXTREMELY VERSATILE LABORATORY SAW. IT CAN BE USED AS A DIAMOND WIRE SAW USING IMPREGNATED WIRE BLADES, WITH AN ABRASIVE SLURRY OR WITH WATER CARRIED BY A STANDARD BLADE TO SLICE WATER SOLUBLE CRYSTALS.WHEN USED AS A DIAMOND WIRE SAW, THE MODEL 850 USES A DIAMOND IMPREGNATED STAINLESS STEEL WIRE BLADE AND A WATER COOLANT IN PLACE OF AN ABRASIVE SLURRY. THIS METHOD IS USED FOR CUTTING HARDER MATERIALS OR WHEN CONTAMINATION FROM AN ABRASIVE SLURRY IS UNDESIRABLE. THE DIAMOND WIRE CANNOT BE USED TO CUT SOFT MATERIALS SUCH AS NICKEL OR COPPER BECAUSE THE SOFT MATERIAL WILL SMEAR OVER THE DIAMONDS AND STOP THE CUTTING ACTION. THESE SOFT MATERIALS CAN BE CUT WITH AN ABRASIVE SLURRY BECAUSE NEW ABRASIVE PARTICLES ARE CONTANTLY INTRODUCED SO THEY CANNOT BECOME “LOADED” WITH THE SOFT MATERIAL.WHEN USED AS A STRING SAW, THE MODEL 850 WIRE SAW CAN CUT WATER SOLUBLE CRYSTALS SUCH AS SODIUM CHLORIDE, BY HAVING A WICK SOAKED IN WATER RUB AGAINST A STANDARD WIRE BLADE. THE WATER IS CARRIED ON THE WIRE BLADE TO THE SAMPLE AND IT CUTS BY DISSOLVING IT’S WAY THROUGH THE CRYSTAL.WHEN USED AS AN ABRASIVE SLURRY WIRE SAW, THE MODEL 850 OFFERS THE MOST GENTLE MECHANICAL METHOD FOR SLICING. THE SLICING IS DONE BY FEEDING AN ABRASIVE SLURRY TO THE POINT OF CONTACT BETWEEN A MOVING STAINLESS STEEL WIRE AND THE MATERIAL BEING CUT. AN ABRASIVE POWDER, SUCH AS SILICON CARBIDE OR BORON CARBIDE IS MIXED WITH GLYCERINE AND WATER TO MAKE AN ABRASIVE SLURRY. THE WIRE BLADE BECOMES IMPREGNATED WITH THE ABRASIVE AND LAPS IT’S WAY THROUGH THE MATERIAL, RESULTING IN A SMOOTH, ALMOST DAMAGE FREE KERF AS SMALL AS 0.004″. WIRE BLADES WITH DIAMETERS OF 0.003″, 0.005″, 0.010″ AND 0.015″ ARE STANDARD.  USING A BLADE THAT IS A WIRE LOOP SUSPENDED BETWEEN TWO PULLEYS, IT IS POSSIBLE TO MOVE THE WIRE MUCH FASTER (30 TO 300 INCHES PER SECOND) AND WITH MUCH LESS VIBRATION THAN IS POSSIBLE WITH THE MORE CONVENTIONAL WIRE SAWS WHICH USE A RECIPROCATING WIRE. THE RESULT IS FASTER AND MORE UNIFORM CUTTING WITH VIRTUALLY NO SAW DAMAGE. ADJUSTABLE WHEEL GUIDES HAVE BEEN ADDED FOR PRECISION CUTTING OF EVEN LARGER DIAMETER SAMPLES.  THE BASE OF THE SAW IS A CASTING DESIGNED TO HOUSE AND PTOTECT THE MOTOR AND THE ELECTRICAL COMPONENTS FROM ABRASIVE CONTAMINATION. THE CONTOURED CASTING ACTS AS A RESERVOIR TO COLLECT THE ABRASIVE SLURRY. THERE IS A DRAIN AT THE REAR OF THE SAW WHICH MAKES IT POSSIBLE TO ADD AN ABRASIVE SLURRY RECIRCULATING SYSTEM. THE CUTTING ARM HAS A LARGE ADJUSTABLE WEIGHT AT ONE END TO BALANCE THE ARM AND A SMALL WEIGHT ON TOP OF THE ARM FOR ADJUSTING THE CUTTING PRESSURE.THIS WIRE SAW IS IN USED BUT VERY GOOD AND CLEAN CONDITION AND GOOD WORKING ORDER. IT COMES WITH THE MICROMETER SLIDE ASSEMBLY AND PLASTIC COVER. PLEASE NOTE THAT THERE IS NO ABRASIVE SLURRY SYSTEM i.e. PUMP OR RESERVOIR INCLUDED WITH THIS SAW. IT WAS USED WITH THE DIAMOND IMPREGNATED BLADES SO HAD NO USE FOR THE SLURRY SYSTEM.ALSO INCLUDES THE ORIGINAL INSTRUCTION MANUAL WHICH INCLUDES CHAPTERS ON : ASSEMBLY, POSITIONING AND TENSIONING THE BLADE, DRESSING THE BLADE, OPERATION, SLICING TIPS, CHOICE OF BLADES, DICING, CUTTING WATER SOLUBLE CRYSTALS AND MUCH MORE.TED PELLA INC. HAS RECENTLY PURCHASED ALL SOUTH BAY TECHNOLOGY’S ASSETS AND ARE SLOWLY INTEGRATING ALL THEIR PRODUCTS INTO THEIR SYSTEM. “AGAR SCIENTIFIC” ARE THE UK’S EXCLUSIVE DISTRIBUTORS AND ARE ABLE TO PROVIDE HELP WITH BLADES, PARTS AND ACCESSORIES. HEAD OF SALES AT AGAR IS JAKE PANESAR WHO COULDN’T BE MORE HELPFUL.IF YOU HAVE ANY QUESTIONS OR WOULD LIKE MORE PHOTOS, PLEASE JUST ASK. I HAVE ADDED AS MANY PHOTOS AS THE LISTING WILL ALLOW BUT BELIEVE I CAN SEND A FEW MORE THROUGH THE MESSAGING SERVICE IF REQUIRED.PLEASE BE ASSURED IT WILL BE VERY SECURELY PACKAGED, POSTED AT COST AND WILL OF COURSE REQUIRE A SIGNATURE UPON DELIVERY.
