    Blade guide parts Band saw blades offer enormous advantages to cutting applications, without requiring any special skills by the operator. A description follows of the blade guide adjustments required to ensure correct operation of the saw. Blade guide heads The first blade adjustment involves adjustment of the heads. The blade guide heads comprise the blade guide plates which ensure correct longitudinal align- ment, the blade steady buttons which control vertical blade flexure, and the coolant supply cocks.

  • Page 115: Front Flywheel

    Front flywheel The front flywheel must be adjusted so that it is aligned with the rear wheel. The purpose of this adjustment is to make sure the back of the blade remains about 1 mm from the edge of the flywheel during rotation. This prevents premature wear to the blade which, due to excessive friction with the edge, may crack.

  • Page 116: Motor Flywheel

    " To adjust, slacken all the locking screws on the flywheel and manually move it in or out until the blade is correctly distanced from the edge of the wheel. Retighten the screws and check alignment by rotating the blade a few times. If necessary, readjust. Use and maintenance manual SHARK 282 7- -20...

    SHARK 282 is built to be sturdy and long---lasting It has no need of any special maintenance, though, like all other tools, it needs adjusting from time to time, especially if not regularly looked over or used without due care.

  • Page 118: Maintenance Requirements

    All ordinary and extraordinary maintenance must be carried out with the power switched off and the machine in emergency condition. To guarantee perfect operation, all spare parts must be MEP S.p.A originals. On completion of maintenance works, ensure that the replaced parts or any tools used have been removed from the machine before starting it up.

Maintenance of working parts In maintenance work on the SHARK 282, special attention should be paid to operating units such as the blade tensioning cylinder, already dealt with in Chapter 7, topping up levels, the air treatment unit, the pneumatic vice on the MA version, and the optional CUT CONTROL SYSTEM.

  • Page 122: Machine With Inverter (Optional)

    MEP S.p.A. Machine with Inverter (optional) The inverter is an electronic instrument fitted to the SHARK 282 for varying spindle motor rpm. The inverter makes life easier for the operator carrying out special cutting tasks by enabling a changing of rotation speed to suit the kind of material being cut.

  • Page 123: Choice Of Blade

    Choice of blade When using band saws to cut metals, an important factor is the choice of pitch, i.e. the number of teeth per inch (25.4 mm.), which must be suitable for the workpiece material. The following recommendations may be taken as general guidelines: thin---walled materials, such as sheet steel, tubes and profiles require a fine pitch frequency.

    300 --- 600 cm Types of swarf: Very fine or fragmented swarf indicates that the downstroke speed and/or cutting pressure is too low. Thick and/or blue swarf indicates that the blade is overloaded. Use and maintenance manual SHARK 282 9- -4...

  • Page 125: Lubricant/Coolant Fluid

    Long coils of swarf indicate ideal cutting conditions. Lubricant/coolant fluid The lubricant/coolant fluid must ensure so that neither the saw teeth nor the work piece material in the cutting zone overheat. Furthermore, there must be a sufficient quantity and pressure of lubricant/coolant to remove swarf from the cutting zone.

    N.B. Blade types The blades mounted on the SHARK 282 are 2.950 x 27 x 0.9 mm.; the length can vary between 2.960 mm. and 2.940 mm., thanks to the blade tensioner device. The blades, however, apart from size and tooth pitch, are differentiated by other geometrical characteristics which determine their specialised uses: tooth cutting angle (rake), can be 0 or positive;...

  • Page 127: Conventional Rake

    Conventional rake Cutting angle 0° , constant pitch. In general use, for small or medium section cast iron or steels and rolled materials, for straight or angled cuts. Positive rake Positive cutting angle 9---10° , constant pitch. Can be used for cutting all types of materials, and is particularly suited to low---carbon and non---ferrous steels.
