11 Q & A Troubleshooting egarding thread diameter expansion/contraction Suitable tool diameter correction should be performed according to the work material and tool wear condition. Also, please be careful not to forget to input the tool diameter correction value into the machine. Dimensional accuracy worsens when moving toward the bottom of the hole (deflection) A characteristic of the thread milling method is that tool deflection increases as the tool progresses toward the bottom of the hole. It may be necessary to perform zero cutting in order to perform highaccuracy thread milling with low deflection. egarding tool breakage As a countermeasure against tool breakage, performing processing with a reduced feed rate is effective. In addition, when processing with tool extended or when large rough cutting chips are produced, breakage due to chip clogging should be considered. In such cases, if processing is performed with a higher cutting speed, the cutting chips will be broken into smaller bits which may improve conditions. Changes in cutting chip conditions due to different cutting speeds; Simultaneous boring and thread milling (M 1.2) of carbon steel ow Cutting Speed High The NC program created using Mitsubishi Hitachi Tool's NC program creation software doesn't work properly. There are differences in the programming code for the machine being used. lease contact the machine manufacturer for details. egarding machinable nominal diameters Dc lease note that since the Epoch D Thread Mill performs boring simultaneously, it cannot perform thread milling for diameters of more than 1. times the tool diameter Dc. There are no particular similar limitations on using the Epoch Thread Mill. Also, please be aware that if screws of a size smaller than the nominal diameter described in the lineup table are processed, there is a possibility of malfunctioning the screw shape.

12 ねじ切り工具Epoch Thread Mill, Epoch D Thread Mill エポックスレッドミル / エポック Dスレッドミル Cautions regarding use for Epoch Thread Mill/Epoch D Thread Mill About tool feed rate D1 D1 D1 When performing thread milling by helical interpolation, the cutting point feed rate should be multiplied by a coefficient to determine the tool center feed rate. The equation for calculating the tool center feed rate is shown at right. The standard cutting conditions for T and NT threads are calculated based on the nominal diameter D1' at the machinable maximum depth (neck length). Example) Thread milling T⅛ with EDTT1/1ATH D1'=.2 (D1) 1 (under neck length) ¹ (thread taper angle) =.0 vf=fz z n vf Feed rate f z Feed per tooth z No. of flutes n otation D1 Nominal diameter Dc Tool diameter D1Dc D1 About tool diameter correction When performing thread milling by helical interpolation, it may be necessary to compensate for increased cutting resistance due to differences in work materials or tool wear condition. In the NC programs created using Mitsubishi Hitachi Tool's NC program creation software, tool diameter correction is in radius designation format. Correction example : Threading of hardened material (HC) (M1.2) Tool ilot hole dia. ilot hole depth n vcvffz Threading depth Blind hole Threading hole count (holes) Tool dia. correction value (mm) NOT reached tool life. F About coolant The first recommended coolant shown in the table tends to have the superior tool life. When priority is given to finished surface quality, watersoluble cutting fluids are effective. Oilbased cutting fluids are not suitable because they degrade chip removal characteristics. The holder should grip the tool shank so that the holder does not block the hole and the shank projection amount is 1 to 2 times the shank diameter. The coolant nozzle should then be positioned so that the coolant will reach the bottom of the hole. In addition, coolant pressure should be adjusted so that it removes cutting chips. If the setting is bad, cutting chip clogging may lead to flute tip damage or tool breakage. Since there is a risk of cutting chips getting inside the machine, when using tools equipped with oil holes, be sure to perform processing using the oil holes.
