  • Page 22: Blade Basics

    BLADE BASICS Technology is rapidly changing all aspects of production machining. Metal cutoff is no exception. The advances price of high-technology blades. Variable pitch, bi-metal blades (like the 4/6 or ¾ bi-metal blade supplied with the machine) last much longer, cut faster and more accurately than conventional carbon steel blades. In order extremely slow feed rate.

  • Page 23: Optimum Blade Pitch

    OPTIMUM BLADE PITCH Teeth per inch (T.P.I.) Selecting a blade with a proper tooth pitch is important in order to achieve optimal cutting rates and good blade life. many teeth per inch is recommended. For wide materials a blade with a coarse pitch should be used.

  • Page 24: Head Swing And Brake

    BLADE SPEED SELECTION (not applicable to S-23) The blade speed of the S-20 can be changed between four different speeds. The speed is determined by the ratio of the pulleys that drive the V belt. The four pulley sets give the optional speeds of 90, 140, 220 and 310 ft/min.

  • Page 25: Changing Belt Position

    CHANGING BELT POSITION To change the blade speed of the S-20 it is necessary to release the V belt tension and move the belt to another set of pulley grooves. The tension on the V belt is maintained by means of a toggle handle assembly that moves the motor.

  • Page 30: Blade Brush Adjustment

    BLADE BRUSH ADJUSTMENT The machine leaves the factory with the blade brush adjusted for maximum life of the brush. This setting places the ends of the blade brush wires so as to contact the blade at the bottom of the blade gullets. The plastic drive wheel that is driven by the drive wheel face should be held against the blade face with the minimum force that is necessary.

  • Page 31: Head Down Limit Switch

    HEAD DOWN LIMIT SWITCH The head down limit switch operates to cut power to the blade motor and the coolant pump motor when the Head has descended to the bottom of its travel in the Manual mode. The Head is adjusted so that the blade will descend slightly past the level of the vise wear strips.
