How to correctly use nc machine tools
A, processing deformity and eccentric parts should pay attention to what safety matters? Processing deformity and eccentric parts, generally USES the faceplate loading card on the fixed. So first of all should pay attention to put a card. Pawl, clamp don't stretch out faceplate outside diameter, the best adding shield. Secondly to pay attention to eccentric parts of weight. With important appropriate. Weight of the inner hole diameter and screw diameter clearance to small. Machine tool rotary speed is not too high, in case when rotating centrifugal force action will weight offshoring, and machine tool guideway collision, broken screw and wounded operator. Second, the machine tool equipment control system which should satisfy the security requirements? 1, easy operation, reduce the range, avoid unnecessary bend, on tiptoe action. 2, localization is accurate, reliable and prevent a slight vibration occurs misoperation. 3, machine tool equipment operation a movement direction and to be operating unit movement direction should comply with the regulations, and a simple symbols. 4, setting the necessary interlock mechanism, prevent operating a produce not harmonious action, and many people operation not harmonious appear the accident. 5, handle, hand wheel, button structure and arrangement position should comply with the regulations. Start button should be put in the casing inside or installed to prevent accidental touches the protector. Installed in the shaft on stem handwheel, handle, in the automatic feed, can follow shaft rotation hurt, so should be installed automatic emersion device. Three, prevention chip to human body harm security measures have? 1, according to be processing of material properties, change tool Angle or increase the chip breaker device, choose the right amount of feed, will strip chip broken into small section roll shape or block chip, try to clear. 2, on the tools installation clearance apparatus, or in the machine installation shield, baffle plate, the control chip flow, not hurt. 3, high speed cutting pig iron, copper, aluminum materials, in addition to machine installation shield, baffle plate outside, the operator should be equipped with safety glasses. 4, use tools keep clear of in time machine and workplace iron filings, prevent hurting hands, feet, avoid by all means use a hand to chop iron filings. Four, machine tool equipment configuration which four safety device what is its action? 1, protective device. Used to make the operator and machine equipment rotating part, energized part and machining process of pests to isolation. Such as the belt cover, gear cover, electrical cover, scrap iron plate washer, protective barrier, etc. 2, insurance device. To improve the working reliability of machine tool equipment. When a component failure or appear overload, insurance device action, quickly stop equipment work or into the no-load operation. Such as gauge, friction clutch, etc. 3, interlocking device. Used to control the machine tool equipment operation sequence, avoid action not harmonious and accident. Such as lathe wire rod and polished rod can't also action, etc., all want to install electrical or mechanical interlocking device to control. 4, signal device. Used for indicating machinery and equipment operation, or in the machinery and equipment operation disorder with a color, acoustics signal, remind operator take emergency measures to deal with. Such as light, buzzer, bell, etc. Five, operating machine to pay attention to what safety matters? 1, before work clothes, firm good cuff, a good working cap. It is strictly prohibited to wear gloves operation. 2, carefully check the equipment parts and cover, limit block, insurance screws and other safety devices are in good condition effectively. 3, the equipment must be firmly effectively grounding joint zero, local lighting for 36 v voltage. 4, before work, in the oil hole lubrication, idle trial confirmed trouble-free can work. 5, machine operation, no hand check workpiece surface roughness and measuring size of workpiece. 6, loading card parts, plate hand to meet the requirements, and shall not add casing in order to increase moment to tighten nut. 7, no hand winding cloth to grind the rotating parts. Eight, to the high speed rotating eccentric workpiece or deformity workpiece to want to add weight and balance test, projecting part and shield. 9, change gear, loading and unloading fixture must be shut off the power and stop stability to 10, automatic feeding ago, adjustment and fastening gauge, and dial out feed pistol. 11, out of hours, to all kinds of feeding handle on gap setting, pull down switch, and to brush try machine cleaning.
