CSM-1    -    MILLING MACHINE
CSM-1V  -    VARIABLE SPEED


The machine uses a 5 bladed cutter with easily replaceable insets, used without any cutting lubricants. Up to 4 specimens can be machined at the same time and these are mounted in a rotating fixture. After the first rotation, which cuts the first side, the fixture is removed and turned through 180° to cut the second side, after which the specimens are remounted in the fixture at 90° to cut the third and fourth sides in a similar fashion. On completion of the fourth side, a 10mm square specimen is achieved, meeting surface finish and dimensional tolerances of all international standards including BSI and ASTM. In its basic form, the machine has a single cutting speed appropriate to users applications. If a wide range of steels is being tested, then the machine can be offered with a variable speed thyristor controlled D.C. drive. The rotating fixture drive on all machines has a variable speed adjustment by thyristor controlled D.C. drive, giving a selectable feed rate. In production the machine will produce complete specimens at the rate of 4 every 8 minutes and is capable of cutting steels up to a hardness of 35 Rockwell C. The machine is sold as a bench top model, requiring only a 10 amp 3 phase electrical supply. A micrometer adjustment is incorporated to compensate for cutter wear and improved tolerance control.
