3 eksen, 5 eksen CNC frezeleme hassas işleme

CNC milling is a high-tech processing method for precision parts, which can be processed into parts with complex structures combined with square and circular shapes.

CNC freze makinesi, dönen gövdelerin karmaşık şekillerini işleyebilir. Frezelemede, ilk önce boşluk düzeltildi, ve gerekli şekil ve özellikleri frezelemek için işlenmemiş parçayı işlenmemiş parça üzerinde hareket ettirmek için yüksek hızlı dönen bir freze bıçağı kullanılır. Geleneksel frezeleme çoğunlukla konturlar ve oluklar gibi basit şekil özelliklerini frezelemek için kullanılır. CNC freze makinesi karmaşık şekilleri ve özellikleri işleyebilir. Frezeleme ve delik işleme işleme merkezi, işleme için üç eksenli veya çok eksenli frezeleme ve delik işleme işlemlerini gerçekleştirebilir: kalıplar, muayene araçları, kalıplar, ince duvarlı karmaşık kavisli yüzeyler, yapay protezler, pervane kanatları, vesaire. CNC freze parçalarını seçerken, CNC freze makinelerinin avantajlarından ve temel işlevlerinden tam olarak yararlanılmalıdır.

Çeşitli malzeme türleri işlenebilir, örneğin 316, 304 paslanmaz çelik, karbon çelik, alaşımlı çelik, alaşımlı alüminyum, Çinko Alaşım, titanyum alaşımı, bakır, ütü, akrilik, Teflon, POM rods and other metal and plastic raw materials.

Tornalama ve frezeleme arasındaki fark

Turning and milling is a common metal cold working method. Tornalamadan farkı, frezelemede, the tool rotates at a high speed under the drive of the spindle, iş parçası nispeten sabitken.
Tornalama ve frezeleme arasındaki fark:
Turning is used to machine rotating parts. The parts are clamped on the main shaft of the machine tool through the three gripping chucks and rotate at high speed. Then use a turning tool to move the tool according to the generatrix of the revolving body to cut out the shape of the product. The lathe can also process the inner hole, iplik, biting, vesaire. The latter two are low-speed processing.

Frezeleme işlemi

(1) Milling the curve contour on the workpiece, straight line, arc, thread or spiral curve, especially the non-circular curve and list curve given by mathematical expression.
(2) Milling the spatial curve or surface of the given mathematical model.
(3) Although the milling shape is simple, the product has a wide range of sizes and positions where internal inspection is difficult.
(4) The milling machine can process cavities, box parts, vesaire. that are difficult to observe, control and detect when processed by ordinary machine tools.
(5) Holes or planes with strict size requirements.
(6) All simple surfaces or shapes can be processed by milling in one clamping.
(7) General processing that can effectively improve productivity and reduce labor intensity by using CNC milling processing.
The main processing objects suitable for CNC milling include the following categories: plane contour parts, değişken eğimli parçalar, spatial curved surface contour parts, delikler ve iplikler, vesaire.

Operation points of milling

1. The milling machine operator should wear tight-fitting work clothes with cuffs tied tightly; Female operators must wear protective caps; Wear protective glasses when high-speed milling; Wear a mask when milling iron castings; It is strictly forbidden to wear gloves during operation to prevent your hands from being caught between the rotating tool and the workpiece.
   
   2. Before operation, check whether the parts and safety devices of the milling machine are safe and reliable;
   Check whether the electrical parts of the equipment are safe and reliable.
   
   3. When loading and unloading workpieces, the workbench should be returned to a safe position. When using a wrench to tighten the workpiece, the direction of force should avoid the milling cutter to prevent the wrench from hitting the tool or fixture when it slips.
   
   4. When assembling and disassembling the milling cutter, use a special pad to pad it. Do not hold the milling cutter directly with your hands.
   
   5. When milling irregular workpieces and using vise, dividing head and special fixture to hold the workpiece. The center of gravity of irregular workpieces, vices, indexing heads, özel armatürler, vesaire. should be placed in the middle of the workbench as much as possible to avoid uneven force and deformation of the workbench.
   
   6. During fast or automatic feed milling, do not move the worktable to the two extremes to avoid squeezing the screw rod.
   
   7. When the milling machine is running, it is not allowed to adjust, measure the workpiece and change the lubrication method to prevent the hand from touching the tool and hurting the fingers.
   
   8. Before the rotation of the milling cutter is completely stopped, it is not allowed to brake by hand.
   
   9. Do not remove the chips by hand or blow with your mouth during milling to prevent the chips from damaging the skin and eyes.
   
   10. During motorized rapid feed, the handle wheel clutch should be opened to prevent the hand wheel from rotating quickly and hurting people.
   
   11. When the workbench is reversing, the reversing handle must be stopped at the middle position first, and then reversing. Direct reversal is not allowed.
   
   12. When milling keyway shafts or milling thin workpieces, prevent the surface of the indexing head or worktable from being milled.
   
   13. When milling a plane, a cutter head with more than four milling cutter heads must be used, and an appropriate cutting amount must be selected to prevent the machine tool from vibration during milling.
   
   14. After work, stop the workbench at the middle position, and drop the lifting platform to the lowest position.
   
   15. For CNC vertical milling machines, pre-select items such as work procedures, spindle speed, tool feed, tool motion trajectory, and continuous offsides according to technological requirements before work. Put the electric knob in the "adjustment" position for trial run. After confirming that there is no problem, put the electric knob in the automatic or semi-automatic position to work.
