Use common type tap, which problems are always happen?<\/p>\n\n\n\n

The main problems often occur in tapping process:<\/h2>\n\n\n\n
  1. Taper broken;<\/li>
  2. Taper broken teeth;<\/li>
  3. Tap wear is too fast;<\/li>
  4. Excessive thread diameter;<\/li>
  5. Too small thread diameter;<\/li>
  6. Surface roughness of threads is too high.<\/li><\/ol>\n\n\n\n

    What cause the tapping problems happen in machining<\/a> work?<\/h2>\n\n\n\n

    1) Tap breakage<\/h3>\n\n\n\n

    The diameter of the bottom hole is small and the chip removal is not good, which results in chip blockage; the depth of the drill hole is not enough when the thread can not be tapped; the cutting speed is too high and too fast when tapping thread; the diameter of the tap used for tapping thread is different from that of the bottom hole of thread; the selection of the grinding parameters of the tap is inappropriate, and the hardness of the workpiece is unstable; the tap is used for too long and wears excessively.<\/p>\n\n\n\n

    2) Tap thread broken<\/h3>\n\n\n\n

    The front angle of the tap is too large; the cutting thickness of each tooth of the tap is too large; the quenching hardness of the tap is too high; the tap is used for too long and wears seriously.<\/p>\n\n\n\n

    3) Tap wears too fast <\/h3>\n\n\n\n

    When tapping threads, the cutting speed is too high; the parameters of tap grinding are not appropriate; the cutting fluid is not selected properly and the cutting fluid is not enough; the material hardness of the workpiece is too high; the burns occur when tap grinding.<\/p>\n\n\n\n

    4) Excessive thread diameter<\/h3>\n\n\n\n

    Improper selection of taper diameter accuracy grade; unreasonable cutting choice; too high cutting speed of tapping thread; poor coaxiality between taper and workpiece thread bottom hole; inappropriate selection of taper grinding parameters; burrs in tap grinding and too short length of tap cutting taper.<\/p>\n\n\n\n

    5) Thread diameter too small <\/h3>\n\n\n\n

    Improper selection of taper diameter accuracy grade, unreasonable selection of taper grinding parameters, taper wear, and inappropriate selection of cutting fluid.<\/p>\n\n\n\n

    6) Excessive Surface Roughness of Thread<\/h3>\n\n\n\n

    The selection of grinding parameters of tap is not appropriate; the hardness of workpiece material is too low; the grinding quality of tap is not good; the selection of cutting fluid is unreasonable; the cutting speed is too high when tapping threads; the use time of tap is too long and the wear is too large.<\/p>\n\n\n\n

    How to solve the tapping problems in machining process?<\/h2>\n\n\n\n

    1) Choose the diameter of the bottom hole of the thread correctly when the tap breaks; the inclination angle of the edge grinding or the selection of spiral groove tap; the depth of the bottom hole should meet the specified standard; reduce the cutting speed appropriately and select according to the standard; correct the tap and the bottom hole when tapping the thread to ensure that its coaxiality meets the requirements, and select floating tapping chuck; increase the front angle of the tap to shorten the length of the cutting taper; and ensure the workpiece. Hardness meets the requirements and safety chuck is selected.<\/p>\n\n\n\n

    2) The breaking teeth of the tap should be reduced properly; the length of the cutting taper should be increased properly; the hardness should be reduced and the tap should be replaced in time.<\/p>\n\n\n\n

    3) Too fast wear of the tap reduces the cutting speed properly; reduces the front angle of the tap, lengthens the length of the cutting taper; chooses the cutting fluid with good lubricity; carries on the appropriate heat treatment to the processed parts; correctly grinds the tap.<\/p>\n\n\n\n

    4) Choose the taper diameter of the reasonable precision grade when the thread diameter exceeds the general one; Choose the appropriate cutting fluid and reduce the cutting speed properly; Correct the coaxiality of the taper and the bottom hole of the thread when tapping the thread, adopt the floating chuck; Reduce the front angle and the rear angle of the cutting taper properly; Clean the burr produced by the grinding taper of the edge, and increase the cutting taper length appropriately.<\/p>\n\n\n\n

    5) Choose the appropriate taper diameter with small thread diameter; properly increase the front angle and cutting taper angle of the taper; replace the worn taper; select the cutting fluid with good lubricity.<\/p>\n\n\n\n

    6) Excessive surface roughness of threads properly enlarges the front angle of the tap and reduces the cutting cone angle; heat treatment is carried out to properly increase the hardness of the workpiece to ensure that the front face of the tap has a lower surface roughness value and select a lubricating cutting fluid; cutting speed is properly reduced; and worn taps are replaced.<\/p>\n\n\n\n
