magnetic roller and the magnetic version (cutting knife version) made major use of the magnetic field theory, a single permanent magnet pieces arranged according to the polarity, stainless steel roller mounted on the base of the tank,outdoor led screen driver due to the polarity of the distribution of outstanding magnetic roller and the permanent magnet produces a strong magnetic force, the use of magnetic attraction to the cutting knife version adsorbed on the roller surface.

usually magnetic roller guard ring (shoulder roll) and the calibration matrix for the stainless steel ring. After hardening for carburizing prolong its life. As the mother of the magnetic roller used roller, so its precision is relatively high,cooler bags wholesale usually require concentricity error of less than ± 2μm. Shoulder roll to roll surface spacing is a very important parameter, according to the product of (mainly thickness) to determine, Europe is using more than 0.48mm.

cutting knife version of the use of chemical etching and mechanical engraving made law. First, the use of chemical etching method. After using the computer typesetting depressed parts of the cutting knife version of the corrosion to a certain depth, on this basis,LED ceiling light re-use of CNC machining centers for machining the cutting knife version, then according to the requirements of small states after the treatment process, such as nickel. Chromium plating, carburizing and laser processing.

knife cutting the J version of the basic parameters are mainly three: cutting angle a, knife and plate thickness of the high-h s. Cutting point of a range of options for the 30 ° ~ 120 °, usually according to the cutting of the material type,renault megane car gps dvd in general, if the material is paper cutting class, cutting knife version of the model should be selected large cut angle; if the version used to process the cutting knife cutting and composite thin film-like material, should select a smaller angle of a knife cutting height h of the range of options between the 0.30mm ~ 1.50mm, high specific knife according to the die to determine the thickness of the material, a knife in Europe 0.44mm high use than more.cosmetic bag Plate thickness h s determined by the knife high, high as 0.44mm in the knife case. Thickness 0.12mm ~ 0.14mm s generally between.

version according to the cutting knife can be divided into general-purpose processing, enhanced (hardening) and laser (manufacture) model,evening bag the use of laser produced version of the knife blade cutting line can be up to the Rockwell hardness hardness of 67 ~ 68 (HRC67 ~ 68).

affect cutting tool life by many factors, such as die-cutting pressures, material type, texture, die-cutting requirements (half or full cut through cut through),Cooling tower ink, machine commissioning and operation of state personnel. It is difficult to give an exact value. Generic version of the life of the cutter mold cut in half through the general conditions of 20 million to 50 million transfer,remy full lace wig enhanced version of the life of the mold cutter cutter mold than the generic version of 40% to 50%, laser (manufacturing ) mold cutter version of the life of the common mold cutter version than the 80% to 100% longer.
