類鑽碳膜（DLC）介紹

鑽石具有高硬度、高熱傳導係數、低膨脹係數、低摩擦系數與高 化學安定度等特性，但鑽石產量稀少、價格昂貴且加工困難，類鑽碳薄膜具有和天然鑽石相近的性質，其中包括了有高硬度、耐腐蝕性佳、表面平滑、摩擦係數小、抗磨耗性佳、生物相容性佳等，且有價格上之優勢。由於具有這些優越特性，使其在機械、電子、半導體等工業之應用日益廣泛。

類鑽碳薄膜是由SP2及SP3組成，如能將SP2晶格減少，且增加SP3晶格，類鑽碳薄膜將會很接近鑽石薄膜，然而由於在結構中含有被扭曲的 sp3 鍵結 Read the rest of this entry »

切削熱的影響

10 九月

切削熱的影響

在銑削難切削材質時，會產生大量的切削熱。所以在加工時，應用充分的大風量油霧冷風槍將切削區淹沒，這對小直徑銑刀OR大直徑刀具容易實現，切削時就不可能全部淹沒，採用乾銑方式。

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!

Characteristics of precision miniature cutting tools

27 六月

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 partIn 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 edgeUnder 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 surfaceSurface 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 surfaceRotary 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 abilityTo ensure working accuracy, miniature cutters should have higher rigidity to reduce the deformation and rebound under cutting force.
  6. Good wear resistance, average wear processThe 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 balanceThe 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 clampingSmall 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.

What’s the difference among tungsten carbide, tungsten steel cutter, and super hard alloy cutter?

13 六月

Cutting Tools: What’s the difference among tungsten carbide, tungsten steel cutter, and super hard alloy cutter?

There are many kinds of different milling cutters. It may be divided into three categories as below according to its applications.

In fact, they are saying the same tool. The component is tungsten carbide (WC) and took part in the P type, M type, and K type. Micro grain carbide tool is made of tungsten carbide and adding some elements to to increase the hardness and abrasion resistance. Super hard alloy cutting tools is named by Japanese, which is also tungsten carbide cutter.

P, M, and K types are divided according to the different turning material.

  • P-type (most common) is suitable for turning mild steel, medium carbon steel, high carbon steel ….
  • K type is suitable for turning of high hardness materials such as cast iron, high-speed steel (HSS) or heat treated material….
  • M type is between the P and, K types which is suitable for difficult material or higher tensile strength material such as tin, hydraulic rod ….

Drill cutter and lathe tool depend on cutting volume.

HSSis suitable to produce drill bit cutters. Tungsten carbide is suitable for small cutting amount, good surface roughness or cutting high hardness material.

Turning tools mostly adopt tungsten carbide material, which is rarely used HSS material, unless for special purposes only!

Tungsten carbide steel is low cost, which applicable range is wider. But in some traditional industries, like automobile/motorcycle industries, pick only one type from P,K, and M type. .. but it is not suitable for optical and optoelectronic industry. Those industries mostly require a high surface roughness (mirror finishing) and the shape accuracy of the tool. Hence the basic knowledge of the diamond tool is very important. The general schools have detailed theory only for HSS high speed steel, tungsten steel tool and cutting tool. But we only know and learn the application and characteristics of diamond toolafter we enter into the community.Not only tungsten carbide or the HSS material, but also you can consider the CBN cutters or diamond tools for non-ferrous metals, the benefits are reducing tool change time and its superior performance and tool life.

Any related questions about various cutting tools and diamond cutter, please feel free to ask us, we would be glad to solve your problem.

波浪槽型銑刀和一般粗銑刀

19 三月

波浪槽型銑刀和一般粗銑刀

一般粗銑刀減少了切削變形，由原來的寬帶切屑分割成數條較窄的切屑，使得銑削過程中切屑的形 成捲曲和排屑情況得以改善，隨之降低了切削抗力，粗銑刀之外周刃為波浪形，由於切屑很細就會斷裂 ，切削抵抗會很小，加工面會呈凹凸不平狀，因此可從事進給大之重切削(粗加工)。

但由於切削振動很大，刀具和機器之接合部很容易變成很粗糙(摩擦腐蝕) ，因此應避免使用於高精 度之機器。特別是乾切削的時候，由於刀具很容易具有高熱，因此應將切削速度降低10至20％左右，以增長刀具壽命。

一般粗銑刀主要是分屑

降低切削力，便與排屑，用於粗加工，基本無特定的加工物件材料。

波浪槽型銑刀多應用於粗中加工上

在粗加工時，針對軟材加工(銅、鋁…)時(吃深排屑量多)，因波浪槽型銑刀排屑槽比一般粗銑刀大，在作切削加工時，可以大量排屑，但對於硬材加工時(吃淺排屑量小)，不要求排屑量時，優勢亦無法凸顯，波浪槽型銑刀也只針對某些材料加工具良好效果，在用於形成刃間的相對切屑厚度不同，可以消除再生顫振，可用於一些難加工材料，特別是鈦合金。

良好4刃波浪槽型銑刀，其各刃波峰波谷區域位置設計不一(錯開)及同一波浪高度(在加工不造成振刀範圍內，角度約可差1-2度)，以達加工省力及延長壽命之目的。但此波浪銑刀製作工序繁複且易磨耗砂輪，對於加工機台損也耗大，相對成本較高，考慮成本上，多數工廠粗加工仍以一般粗銑刀為主。

波浪槽型銑刀優點

  1. 切屑容易變形折斷。切削不但有縱向變形，還有橫向變形，所以容易斷屑。
  2. 實際切削刃增長，便於散熱，減低切削力
  3. 切屑與前刀面粘附力小
  4. 切削平穩。在同一斷面上，它相當於不等齒結構，每條刃波峰波谷，錯開，避免週期性振動。
  5. 可用於精加工。它刃口每一點都處於同一圓柱的表面，因此可用於精加工。
