外文翻譯--臥式銑床的主要部件-10頁[中英word]【中英文文獻譯文】,中英word,中英文文獻譯文,外文,翻譯,臥式,銑床,主要,部件,10,word,中英文,文獻,譯文 The main Elements of Horizontal Milling Machines Column and base The column and base form the foundation of the complete machine. Both are made from cast iron, designed with thick sections to ensure complete rigidity and freedom from vibration. The base, upon which the column is mounted, is also the cutting-fluid reservoir and contains the pump to circulate the fluid to the cutting area. The column contains the spindle, accurately located in precision bearings. The spindle is driven through a gearbox from a vee-belt drive from the electric motor housed at the base of the column. The gearbox enables a range of spindle speeds to be selected. Twelve spindle speeds from 32 to 1400rev/min are available. The front of the column carries the guide-ways upon which the knee is located and guided in a vertical direction. Knee The knee, mounted on the column guide-ways, provides the vertical movement of the table. Power feed is available, through a gearbox mounted on the side, from a separate built-in motor, providing a range of twelve feed rates from 6 to 250mm/min. Drive is through a lead-screw, whose bottom end is fixed to the machine base. Provision is made to raise and lower the knee by hand through a lead-screw and nut operated by a hand-wheel at the front. The knee has guide-ways on its top surface giving full-width support to the saddle and guiding it in a transverse direction. A lock is provided to clamp the knee in any vertical position on the column. Saddle The saddle, mounted on the knee guide-ways, provides the transverse movement of the table. Power feed is provided through the gearbox on the knee. A range of twelve feeds is available, from 12 to 500mm/min. Alternative hand movement is provided through a lead-screw and nut by a hand-wheel at the front of the knee. Clamping of the saddle to the knee is achieved by two clamps on the side of the saddle. The saddle has dovetail guide-ways on its upper surface, at right angles to the knee guide-ways, to provide a guide to the table in a longitudinal direction. Table The table provides the surface upon which all work-pieces and work-holding equipment are located and clamped. A series of tee slots is provided for this purpose. The dovetail guides on the undersurface locate in the guide-ways on the saddle, giving straight-line movement to the table in a longitudinal direction at right angle to the saddle movement. Power feed is provided from the knee gearbox, through the saddle, to the table lead-screw. Alternative hand feed is provided by a hand-wheel at each end of the table. Stops at the front of the table can be set to disengage the longitudinal feed automatically in each direction. Spindle The spindle, accurately mounted in precision bearings, provides the drive for the milling cutters. Cutters can be mounted straight on the spindle nose or in cutter-holding devices which in turn are mounted in the spindle, held in position by a draw-bolt passing through the hollow spindle. Spindles of milling machines have a standard spindle nose to allow for easy interchange of cutters and cutter-holding devices. The bore of the nose is tapered to provide accurate location, the angle of taper being 16.36”. The diameter of the taper depends on the size of the machine and may be 30, 40 or 50 IST (International standard Taper). Due to their steepness of angle, these tapers-known as non-stick or self-releasing-cannot be relied upon to transmit the drive to the cutter or cutter-holding device. Two driving keys are provided to transmit the drive. Over-arm and arbor support The majority of cutters used on horizontal machines are held on an arbor which is located and held in the spindle. Due to the length of the arbors used, support is required at the outer end to prevent deflection when cutting takes place. Support is provided by an arbor-support bracket, clamped to an over-arm which is mounted on top of the column in a dovetail slide. The over-arm is adjustable in or out for different lengths of arbor, or can be fully pushed in when arbor support is not required. Two clamping bolts are provided to lock the over-arm in any position. The arbor support is located in the over-arm dovetail and is locked by means of its clamping bolt. A solid bearing is provided in which the arbor runs during splindle rotation. Controls of Horizontal Milling Machines The various controls of a typical horizontal milling machine. These are identical to those of a vertical machine: Spindle speeds are selected through the levers 4, and the speed is indicated on the change dial 5. The speeds must not be changed which the machine is running. An ‘inching’ button 3 is situated below the gear-change panel and, if depressed, ‘inches’ the spindle and enables the gears to slide into place when a speed change is being carried out. Alongside the ‘inching’ button is the switch for controlling the cutting-fluid pump 1 and one for controlling the direction of spindle rotation 2. The feed rates are selected by the lever 9 and indicated on the feed-rate dial. To engage the longitudinal table feed, lever 8 is moved in the required direction-right for right feed, lever 8 is moved in the required direction-right for right feed, left for left feed. Adjustable trip dogs 6 are provided to disengage the feed movement at any point within the traverse range. Limit stops are incorporated to disengage all feed movements in the extreme position, to prevent damage to the machine in the event of a trip dog being missed. To engage cross or vertical traverse, lever 12 is moved up or down. The feed can then be engaged by moving lever 11 in the required direction. With cross traverse selected, movement of lever 11 up-words produces in-feed of the saddle, moving it downwards produces out-feed of the saddle. With vertical traverse selected, movement of lever 11 up-words produces up-feed to the knee, moving it downwards produces down-feed to the knee. Rapid traverse in any of the above feed directions is engaged by an up-ward pull of lever 10. Rapid traverse continues as long as up-ward pressure is applied. When released, the lever will drop into the disengaged position. Alternative hand feed is provided by means of a single crank handle 7,which is engaged by slight pressure towards the machine. Spring ejectors disengage the handle on completion of the operation, for safety purposes-I. E. the handle will not fly round when feed or rapid traverse is engaged. The single crank handle is interchangeable on table, saddle, and knee movements. Milling Operations The variety of milling operations which may be performed on a given milling machine depends on the type of machine, the type of cutter used, and the accessories or attachments available for use with the machine. Milling machine are used for machining flat surfaces, including horizontal, vertical, and angular surfaces. They are used for machining many kinds of shoulders and grooves, including keyways, T-slots, and dovetails. They are used to machine formed or irregular surfaces with the use of many types of formed-tooth cutters. Milling machines equipped with a dividing head may be used for machining equally spaced flat surfaces, straight grooves, or spiral grooves on parts with a cylindrical shape. This type of machining is involved in making gears, taps, reamers, drills, milling cutters, and splines on shafts. Milling machines, particularly those of the vertical type, may be used for all of the common hole-machining operations which normally are performed on a drill press. With the milling machine, holes may be precisely located through the use of the table feed screws. The longitudinal and cross-feed screws are equipped with micrometer collars accurately graduated in hundredths of a millimeter (thousandths of an inch)or smaller. Hole depth also may be accurately controlled through the use of graduated collars on the vertical-feed control. Because of the wide variety of operations which may be performed on a milling machine and because of its general efficiency and speed of metal removal, it is one of the most important of the basic machine tools. It ranks in versatility and importance with the metal-working lathe. Safety and Maintenance For CNC Machine Safety Notes for CNC machine operations Safety is always a major concern in a metal-cutting operation. CNC equipment is automated and very fast, and consequently it is a source of hazards. The hazards have to be located and the personnel must be aware of them in order to prevent injuries and damage to the equipment. Main potential hazards include: rotating parts, such as the spindle, the tool in the spindle, chuck, part in the chuck, and the turret with the tools and rotating clamping devices; movable parts, such as the machining center table, lathe slides, tailstock center, and tool carousel; errors in the program such as improper use of the G00 code in conjunction with the wrong coordinate value, which can generate an unexpected rapid motion; an error in setting or changing the offset value, which can result in a collision of the tool with the part or the machine; and a hazardous action of the machine caused by unqualified changes in a proven program. To minimize or avoid hazards, try the following preventive actions: (1) Keep all of the original covers on the machine as supplied by the machine tool builder. (2) Wear safety glasses, gloves, and proper clothing and shoes. (3) Do not attempt to run the machine before you are familiar with its control. (4) Before running the program, make sure that the part is clamped properly. (5) When proving a program, follow there safety procedures: Run the program using the machine Lock function to check the program for errors in syntax and geometry. Slow down rapid motions using the RAPID OVERRIDE switch or dry run the program. Use a single-block execution to confirm each line in the program before executing it. When the tool is cutting, slow down the feed rate using the FEED OVERRIDE switch to prevent excessive cutting conditions. (6) Do not handle chips by hand and do not use chip hooks to break long curled chips. Program different cutting conditions for better chip control. Stop the machine if you need to properly clean the chips. (7) If there is any doubt that the insert will break under the programmed cutting conditions, choose a thicker insert or reduce feed or depth of cut. (8) Keep tool overhang as short as possible, since it can be a source of vibration that can break the insert. (9) When supporting a large part by the center, make sure that the hole-center is large enough to adequately support and hold the part. (10) Stop the machine when changing the tools, indexing inserts, or removing chip. (11) Replace dull or broken tools or inserts. (12) Write a list of offsets for active tools, and clear (set to zero) the offsets for tools removed from the machine. (13) Do not make changes in the program if your supervisor has prohibited your doing so. (14) If you have any safety-related concerns, notify your instructor or supervisor immediately. 2. Daily Maintenance <1>Checking the External View (1) Machine oil (cutting oil, lubrication oil) has been scattered onto the servomotor, detector, or main unit of the NC, or is leaking.

During I/O operation? Machine system status? During tool change? Controlled axis hunting? What fault occurred? What does the alarm display of the set/display unit’s alarm diagnosis screen indicate? Display the alarm diagnosis screen to check the contents of alarm. What dose the driving amplifier status display indicate? Check the contents of alarm based on the driving amplifier status display What dose the machine sequence alarm indicate? Is the CRT screen normal? Is the control axis hunting? (3) Frequency of fault? When did the fault occur? Frequency? (Did the fault occur during operation of another machine?) If the frequency is too small, or the fault occurred during operation of another machine, the cause may be noises of the supply voltage. For example, in this case, check that 1 the supply voltage is normal (does momentary drop occur during operation of another machine?) and 2 measures have been taken against noises. In specific mode? When did the ceiling crane move? Frequency for the same kind of work? Dose the fault occur when the same operation is made? (Repeatability check) Change the conditions (override, contents of program, operating procedure, etc.). Dose the same fault occur? 2. Fault Example (1) The power cannot be turned on. Check the following points: The power is being supplied? (2) The NC unit dose not operate when being activated. Check the following points: Mode selected normally? All conditions for start satisfied? Depending on the machine, the start may be locked until the predetermined conditions are satisfied. Check this by referring to the manual published by the machine manufacturer.
