Sunnen 1804 Honing machine with automatic sizing

Sunnen 1804  It hones to size. It stops. AUTOMATICALLY You could always depend on Sunnen Honing for accuracy. Then Sunnen added Power Stroking to make it fast and easy. And now the finishing touch... AUTOMATIC SIZING. Sunnen has put it all together for you. SUNNEN HONING. The simplest, most productive bore control system in the world. At a price that makes it practical for any size shop. Sunnen Honing Biggest Bargain in Metalworking An automatic sizing system so simple and foolproof it could only come from Sunnen. How It Works Low-Cost, Adjustable Plugs You set the diameter of the sensing tip, Nitrided sensing tips are adjustable so you The Plug to about .0003 smaller than the can set size exactly where you want it. high, finish diameter of the bore being honed. The low, or in the middle of your tolerance. sensing tip is prepositioned so that it will This adjustment compensates for wear... enter a to size bore as the workpiece moves back through its last la increment of stroke. You can also use the same sensing tip for rough and finish honing. In the /a to 1 diameter range, Mandrel Workpiece sensing tips consist of a split plug with central

Stone adjusting screw. Useful diameter range is approximately .015 For diameters from 1 to 2; sensing units consist of a split plug with four radial adjusting screws. The radial screws are preset central UNDERSIZE Sensing Tip and to size with the aid of a micrometer- type setting fixture. A central adjusting screw in the split plug is provided for final trim. The C entire diameter range from 1 to 2 is covered by four split plug/radial screw assemblies. A full range of sensing tips a through 2 TO SIZE diameters and the micrometer setting fixture are stocked and available for immediate delivery. See back page. As long as the bore is undersize the sensing tip will be depressed at the back end of each stroke, and the stroking circuit will be energized for one more stroke. As soon as enough stock is removed, the sensing tip slips into the bore. The stroking circuit is de-energized and the honing cycle stops automatically. The bore is to size and the machine is ready for the next honing cycle. All Electric, All Enclosed Sensing and switching circuits are all solid state. No exposed contacts or switches to maintain. Sealed control box, completely outside the work area, protects circuitry from dirt and honing oil. New Sunnen Stone Saver Eliminates the biggest cause of excessive stone wear. It cushions out the initial shock and shearing action at the beginning of the honing the stone first contacts the bore. This cushioning action is infinitely variable, so the initial feed rate can be optimized for a wide range of rough bore conditions. It minimizes piece-to-piece variation in finish bore size and surface roughness. And in many cases, eliminates deburring or pre-honing in extra rough workpieces.
