Universal Cutter & Tool Grinder M-40 Handling of Machine Lifting the machine When lifting up the machine transported into the factory by train or truck, fix the table at the middle of the bed (fasten (30) in Fig. 1) and set the dogs (7) ac right and left shown in Fig. 1, on stoppers (9) as illustrated in Fig. 3, and then move the wheel head to the table as closely as possible. The wire ropes no be used for this work should be strong enough to withstand a weight of 2000 kg. ( 4400 Ibs.). The portions where the wire ropes may touch should be protected from any crush, which may cause some inaccurate movements later on. Inspection and cleaning of machine An inspection to find some damaged portion, which might have been caused by shock during the transportation, as well as to find if there are some parts, the standard equipment missing, should be made after the arrival of the machine in your works. The dirty spots possible made during the packing of the machine should be cleaned, and the antirust liquid should be thoroughly washed out by proper oil. Foundation and installation The machining accuracy obtained owes very much to the foundation and installation of the machine. For this reason, a perfect foundation with proper thickness and pressure-enduring space must be provided according to the ground nature, as specified in Fig. 2, "floor plan". (In general case, a thickness of 300 mm (12") is considered to be enough.) If the concrete floor of your words is originally provided with enough strength, there is no need to make up a special foundation, When the machine is now placed on the installing place, fix it with the fixing device at three portions, each consisting of leveling boll (33), nut (34) and leveling pad (35), (see Fig. 1, and by which level up the machine in either longitudinal or cross direction using a leveling device for precision measurement Wiring After installing the machine, connect the wires of the power source to the terminals (R., S, T). (1), for 3-phase supply, which you see among the terminals equipped in the electro-magnetic control box, when you open the cover by the provided handle. Confirm that the power source plug for grinding spindle motor is inserted in the socket illustrated in the Fig. 9, as 1. Now the power source indication lamp [(2) in Fig. 7] will be lighted when you set the main switch [(1) in Fig. 7] "ON". Then turn the selection switch for grinding spindle [(3) in Pig. 6] to the right. The grinding wheel spindle will then rotating in counter-clock-wise direction, viewed from the opposite side of the belt-cover [(19) inFig. l], the spindle is running in the

specific direction. However, should you find it running in clock-wise direction, it is reversed rotation? Lubrication Special care on lubrication should be taken to maintain the service life and performance of the machine for a long period. For this reason, specified oil given in the table, or oil of equal or better quality, must be used for the respective parts in Fig. 4. The built-in lubrication pump (1) is capable of containing 1 litter (61 cubic inch) oil. Structures and Operation Electrical equipment The electrical equipment consists of electro-magnetic control box (27) in Fig.' 1, and electrical control panel (32) in Fig. 1, on the basis of the wiring diagram given in Fig.10. Figure 8 illustrates the side-view of the electro-magnetic control box; (1) is the power source switch and (2) is an white power source indication lamp (lighted when the main switch is set "ON" ); (3) is operation signal lamp (green) (lighted when the motor in Fig .10 starts ). The electric control panel is situated at the left side of the machine. Figure 9 illustrates the side-view of the electromagnetic control box, and shows (I): grinding wheel spindle motor, (2): socket for main spindle motor, (3): socket for dust collector motor, (4): socket for wet grinding attachment or mist type coolant system and (5): socket for machine illumination. When starting the grinding wheel spindle, please follow the order given in .the item D ("Handling of machine" as well as 2), "Wiring".

Safety precautions (1) Dust insulation glasses Please always wear dust. Insulation glasses to protect your eyes from dust, when grinding. (2) Wheel Guard The wheel guard is so provided that the pieces of the wheel will never scatter, when the wheel breaks. The wheel should always be covered with the wheel guard. (3) Setting up of grinding wheel The grinding wheel shall be installed on the grinding wheel spindle with the wheel sleeve (10), washer (1), washer with rubber (12) and the nut (13); standard equipments, illustrated in Fig. 17. Next, the wheel sleeve mentioned above shall be fixed on the extended spindle by the perforated bolt (16) with the spring washer (15) in between. The dished wheel shall be fixed on the extended grinding wheel spindle, while the grinding wheel shall be fixed on the extended spindle with the washer in between. When using a grinding wheel, which is not listed in the standard equipments, you shall first select the speed of the wheel from Table 2, which is lower than the permissible speed, but meets the required speed for grinding the workplace. In such case, the wheel should be fixed on the spindle with some washer or the washer with rubber; in event you cannot use the washer and the washer rubber. You may use some blotting paper or leather, but the thickness of the paper should not exceed 0.6 mm (0.025"), while the one of the leather* 3 mm (0.1"). The outside diameter of the washer should be the same or a little bigger than the one of the wheel sleeve. When fastening the wheel sleeve, washer, grinding wheel, washer attention to ascertain that there is no alien substance among them. (4) Inspection and storage of grinding wheel The experts should be In charge of installing the wheel, maintenance and the inspection of the wheels. Inspect the wheels as soon as they are delivered to you, Co find If there is some damage on them caused during transportation. It can be judged by the sound coming out: from the wheel, when striking the wheel, bunging down, with a shank of a screwdriver, to find whether or not the wheel has a crack. In this inspection, you must take off the sawdust, if any; or you must dry the wheel, if it is wet. The wheel composed of an organic substance does not sound as well as the wheel made of vitrified or silicate substance does, and therefore, you need Co listen co the sound carefully Co find whether or not the wheel has any crack. It is desirable to keep the wheels in a rack hanging from a nail respectably in a place where it is dry.

(5) Operation rules and. general precautions on works Before you actually start a grinding work with a new wheel, check the wheel by turning it at the full speed for a minute. In this case, the operator should carefully inspect the wheel running standing aside. The work piece should be gradually ground so as to heat up the wheel, which at the beginning may be cold. This way of work will prevent the wheel from becoming damaged. Special care should be taken on the above matter, when using a cold wheel soon after it is brought in from cold storage, or an early cold morning. The grinding work with the flank of a flat wheel is generally accompanied with danger. You must not, therefore, start grinding until the wheel flank is properly heated up, or you must not push strongly the work piece to the wheel. The wheel-fixing nut should not be too strongly fastened, otherwise, the wheel will be deformed, and the relating pans will be broken. The machine, except the machine equipped with a mist type coolant system, should be equipped with a dust collector (extra attachment) for an insurance purpose.
