研磨與拋光介紹

研磨拋光(Polishing or Lapping)是使工件產生平滑鏡面的超精密研磨技術，其目的在於使表面粗糙度及平坦度到達一定的可容許範圍，常被廣泛的使用在硬脆金屬、陶瓷、玻璃及 晶圓等材料表面的精密加工。

研磨-研磨與拋光介紹

研磨

研磨工作方式：

研磨加工通常使用1μm到幾十μm磨粒和鑄鐵等硬質材料的研具。

  • 磨粒在工件與研具之間進行轉動
  • 由研具面支撐磨粒研磨加工面
  • 由工件支撐磨粒研磨加工面

研磨特性：

  • 硬脆材料的研磨
    • 微小破碎痕跡構成的無光澤面。
    • 磨粒不是作用於鏡面而是作用在有凸凹和裂紋等處的表面上，並產生磨屑。
  • 金屬材料的研磨
    • 表面沒有裂紋。
    • 對於鋁材等軟質材料，研磨時有很多磨粒被壓入材料內；對刀具和塊規等淬火工具鋼等可確保有塊規那樣的光澤表面。

拋光-研磨與拋光介紹

拋光

拋光工作方式：

  • 使用<1μm的微細磨粒。
  • 軟質材料拋光墊：瀝青、石蠟、合成樹脂和人造革等。
  • 微小的磨粒被拋光器彈性地夾持研磨工件。因而，磨粒對工件的作用力很小，即使拋光脆性材料也不會發生裂紋。

 

研磨特性：

  • 由磨粒進行的機械拋光可塑性地生成切屑。但是它僅利用極少磨粒強制壓入產生作用。
  • 借助磨粒和拋光器與工件流動摩擦使工件表面的凸因變平。
  • 在加工液中進行化學性溶析。
  • 工件和磨粒之間有直接的化學反應而有助於上述現象。

Cutter selection Part-1

Cutter selection

Only correct type and cutting edge may do a good job for milling work. Popular end mills include flat cutter, side cutter, face milling cutter, milling cutter, end mill, sawing, and milling cutter. Its characteristics is that many teeth and flutes on one milling cutter, some end mills with only two or three teeth; some cutters are with considerable numbers of teeth. Hence end mill is called as multi-teeth cutters.

There are many types of cutters and a variety of classification methods as below:

Classify by material：

  1. High-speed steel cutters:for general purposes, the most widely used.
  2. Carbide cutter:for high speed cutting.
  3. Non-ferrous metal casting alloy cutter:suitable for heavy cutting.

Classify by the way of grinding wheel:

  1. Contour cutter.
  2. Type cutter.

Classify by tool installation:

  1. Spindle cutter device:set cutter by use of the tool axis, which with a hole in the center of milling cutter, and used in horizontal milling machine.
  2. Shank type milling cutter:cutter body with straight shank or taper shank, it needs to be fixed by a chuck or socket for installation.
  3. Face Mills:This cutter is with a short cutter shaft, it needs to be settled by cutter shaft device then set on the spindle of milling machine directly for installation.

Classify by cutter structure:

  1. Overall cutter:body and cutting edge made by the same material as a whole, generally adopt high-speed steel.
  2. Brazed cutter:cutting blade made with carbide, the body is high carbon steel, combined by brazed joint.
  3. Welding blade cutter: cutting blade made with high carbon steel or tool steel, high-speed steel, ontology Ministry both to weld joints.
  4. Inlay cutter:blade screwed on the body, you can remove it to grind or replace, mostly used in face milling cutter of big diameter.

The next article will introduce cutters classified by the appearances and applications, so stay tuned!

tool,What is cutting tool?

There are lots of metal products around us in our life, but we all know how they are produced?

There are many processing methods to make metal, cutting is the major one among them.

Firstly, let's learn about cutting tool and machining! We often talk about cutting tool. However, what is cutting tool?

At first, we should think about cutting tools around us.

There are a number of cutting tools in our lives .., kitchen knife, knives and other cutting tools (rub the radish), paper knife and pencil sharpener of the table, the saw and plane of tool box and so on, these also belong to cutting tools. Cutters change shape of objects through cutting, and produce cutting debris.

We should have understood that cutting tool is the tool that may change the shape into our expected form through cutting. The cutters in life includes fruit knife, vegetable knife, and cutting saws for wood, etc.

tool,Characteristics of precision miniature cutting tools

Four major cutting method:

  1. Precision micro turning
  2. Precision micro milling
  3. Precision micro fly cut
  4. Precision micro drilling

There are precision micro turning tools,flat end mills, ball end mill, throwing cutter, and drills according to these applications. The working conditions, friction, impact, and cutting resistance are much worse because of the limitation of size, which is different from normal spec tools.

Basic requirements for miniature cutters:

  1. Small work piece and micro machining part

    In order to fit the characteristics of tiny machining, high machining accuracy and avoid interference between the work piece and the cutter, the whole work piece and the machining scale must be synchronized reduced.

  2. Sharp cutting edge

    Under micro cutting conditions, in order to achieve a very small amount of material removed, the depth of cut and feed rate is usually in the micron level, the cutting edge should be sharp enough.

  3. Good quality of surface

    Surface quality influences the performance of the micro-cutting tools a lot, poor surface quality will not only increase the frictional resistance and lead to the deterioration while fine cutting, but also weaken the toolstrength.

  4. Good quality of surface

    Rotary tools like the small diameter of end mills and drills, micro-cutting is carried out under high spindle speed.The cutting part of cutters should have sufficient strength and dynamic characteristics, which are able to afford the high impact load.

  5. Rigid, anti-deformation ability

    To ensure working accuracy, miniature cutters should have higher rigidity to reduce the deformation and rebound under cutting force.

  6. Good wear resistance, average wear process

    The cutting part of the micro cutting tools should have enough hardness to ensure its abrasion resistance.Blunt cutter will not only affect its machining accuracy, but also happen processing glitches which will bring difficulty of surface finishing.

  7. High accuracy of dynamic balance

    The run out feed rate of micro cutter is significantly greater than cutting for normal size... Under high spindle speed, the cutting edge between the cutting load is very uneven, the cutting force fluctuation is serious, the tip trajectory and accuracy of processing, the tiny end mills, drills and other rotary tool should have high accuracy of dynamic balancing.

  8. Accurate and reliable tool clamping

    Small rotary tool installation error is the main factor to influence the machining accuracy and reliability. The tool clamping system should have high contact rigidity, accuracy of repeating position, and good speedy locking.

Material of micro cutters

It is a very important mean to choose the advanced and applicable tool material, which may ensure the whole performance of micro tools .. The ideal materials for miniature cutters are diamond, fine grain and ultra-fine grain carbide.

Characteristics and processing differences of the four kinds of cutting tools : Plain Milling Cutter, End Mill, Side Milling Cutter, and Face Milling Cutter

Characteristics and processing differences of the four kinds of cutting tools?

  1. Plain Milling Cutter：

    Plain Milling Cutter-Characteristics and processing differences of the four kinds of cutting tools : Plain Milling Cutter, End Mill, Side Milling Cutter, and Face Milling Cutter

    Plain Milling Cutter is the most commonly used tool in a horizontal milling machine. Plain Milling Cutter’s shape is like disc or cylindrical, which has blades on the outer circumference of the cutter for milling the plane which parallel to the cutter axis. The blade shapes include straight and helical blade-shaped. Generally helical blade shape is more commonly used. If the blade width is less 20mm, it is only suitable for light milling and milling hard materials because of its multi blades and small chip slots; if the width is over 20mm, it’s often designed as helical teeth in order to reduce the shear force and prevent vibration during milling, with fewer blades, so the chip slot is larger which is suitable for heavy milling and cutting soft materials.

  2. End Mill：

    End Mill-Characteristics and processing differences of the four kinds of cutting tools : Plain Milling Cutter, End Mill, Side Milling Cutter, and Face Milling Cutter

    Such cutters have a flute in the circumferential surface and the end for milling flat, face, shoulder angle and groove .There are straight shank, taper shank, straight flute, helical flute, double flute, multi-flute, and so on.

  3. Side Milling Cutter：

    Side Milling Cutter-Characteristics and processing differences of the four kinds of cutting tools : Plain Milling Cutter, End Mill, Side Milling Cutter, and Face Milling Cutter

    The shape of the side milling cutter is similar to the straight flute face cutter. Except the shape and function of end mills, its side also has cutting edge, which can milling the face and the side of work piece. Edge shape can be divided into straight teeth, spiral teeth and staggered teeth. Staggered teeth may be offset against each other and reduce vibration during machining, which is suitable for heavy milling.

  4. Face Milling Cutter：

    (Face Milling Cutter-Characteristics and processing differences of the four kinds of cutting tools : Plain Milling Cutter, End Mill, Side Milling Cutter, and Face Milling Cutter

    Face milling cutter is a disc-shaped, with cutting blades around the body and the side face. Such cutter is specialized in cutting larger plane. The blade face is wider, and the cutter body is made of general tool steel, then embedded high-speed steel or carbide blade.
