h. Whether the workpiece is clamped internally or externally. These factors must be carefully noted. As these factors have different effects due to their different uses, therefore, the manufacturer is impossible to provide specific parameters for general use, because these factors are beyond the range of the control of a machine tool manufacturer. - Page 14 correct. 15．Care should be taken to ensure that the locking screw must be tightened. 16．When the preparatory work has not been finished, do not hurry up for operation. 17．Without the right tools, or not equipped with the right tools in the workshop, do not use alternative tools.
- Page 15 as to prevent the danger of the hair from being rolled into the rotating part of the machine tool. 32．When carrying out other operations close to the rotating part of the machine tool, special attention should be paid to safety. 33．Attention should be always paid to the operations of filing it smooth and deburring.

48．Tighten all the jaws, nuts, screws and fasteners. 49． Always pay attention to use the correct equipment. 50．Be sure not to carry out any cutting that exceeds the capacity of the machine tool. 51．When polishing and deburring, do not be too hard. 52．Always pay attention to use the proper tools for deburring, do not be in a hurry, when deburring and pay attention to the burrs on the chuck and the workpiece. -
Page 17: Danger Of Accident Resulted From Using Emery Cloth In Metal Processing
2.3.4 Danger of Accident Resulted from Using Emery Cloth in Metal Processing In all the incidents occurred in the lathe,a great part of them results from using emery cloth and leading to fingers broken and even amputation in rare cases. When various shapes of the workpieces are rotating in the lathe, if emery cloth is used for deburring, polishing or machining to size, when both ends of emery cloth are taken in... -
Page 18: Noise Level
c.Use two wooden plates connected together with emery cloth to form into a special-purpose “Strong Polisher" for polishing and its holes may let the workpiece pass through the surface to be polished. d.Use a sturdy wire brush stuck with abrasive material for polishing. -
Page 19: Installation
If the unstable state of the input voltage exceeds the allowable limits, it is impossible then for the machine tool to achieve the rated horsepower of the machine tool. The machine tool can be running normally, but it is in no way to transfer the power as indicated. The reliable ground is a guarantee for the personal safety and the safe operation of the machine. - Page 20 Please be careful to unpack the case and check and estimate that there is no part damaged or injured. If parts found lost and damaged obviously, please contact this company timely. Note: Due to the fact that CQ0618 series has a variety of configurations, if there is discrepancy between the text and the actual product, the manufacturer and this company reserves the right of final interpretation.

electronic circuit board has a protective function, if accelerating too quickly, it may cause a circuit failure, while the lathe will not start. 3.Having lasted in this way for 1-2 minutes, the spindle speed is increased gradually from the lowest speed and runs for a few minutes before stopping. Stop the machine tool and check all parts, so as to make sure that everything works smoothly. - Page 24 Lathe Chuck he 3-jaw chuck equipped with two sets of clamping chucks, which are called positive-jaw chuck and anti-jaw chuck, supplied in accompaniment with the machine tool as shown in the figure. The positive-jaw chuck is used to clamp the workpiece from its internal or external side ( the internal or external side suitable for comparatively small diameter workpicecs).

chuck and a 4-jaw chuck shall be mounted to fulfill the job. ☞ Three is always a small jerking motion in the 3-jaw chuck. When the 3-jaw chuck is used to clamp the workpiece, it is recommended to measure the concentricity of it. If the test value is too high, it is recommended to use a 4-jaw chuck instead of the 3-jaw chuck, use a concentricity meter for a test and adjust the workpiece until its best position is achieved. -

As long as the hand crank going back is avoided, continue to move longitudinal carriage in the same direction and readings shown in the dial plate on the hand crank will be accurate. -
Page 28: Change Gears
normal rotation of the feed rate is much lower than the thread cutting. Therefore, it is very important that, when cutting threads, the combination of the gears must be checked to be correct. The lathe is set up according to the normal rotation speed before delivery from the factory. - Page 29 During the period of the engagement of the change gears, first cut off the power. Turn the switch of the machine tool to the "Off" position and then loosen the two hexagon socket head cap screws on the gear housing to dismount the housing. The simple gear rotation structure is illustrated on the left and the intermediate idler gear is illustrated on the right in the figure above and, as long as the size of the gears can meet the...
