如何讓銑刀排屑呈現片狀而且可以規定排屑長度與面積?

切削加工中,崩碎切屑會飛濺傷人且易磨損機床, 通常排屑規範是因為在操作CNC設備加工工件時,排屑會造成工件表面刮痕,使 得工件鏡面會有刮傷,例如:長條帶狀切屑會纏繞在工件或刀具上,易刮傷工 件引發刀具破損,甚至影響工人安全等。

對於CNC機床等自動化加工機床,由於其刀具數量較多,刀架與 刀具聯系密切,斷屑問題就顯得更為重要,只要其中—把刀斷屑不可靠,就可能破 壞機床的自動迴圈,甚至破壞整條自動線正常運轉,排屑是屬於回收物料,所以通常不在 乎長度與面積大小,所以在設計、選用或刃磨刀具時,最重要是考慮刀具斷屑的 可靠性(包括工件不刮傷…)。

建議處理方式:

  1. 當刀具在切割工件時其溫度需控制,刀具會產生高溫讓排屑帶走高 溫,排屑會因二度高溫造成硬化,使排屑輕易刮到工件。
  2. 排屑會因加工路徑改變呈現出來排屑也有不同,可以利用CNC路徑 程式達到片狀切屑長度與面積相同。
  3. 經過專門設計銑刀也可以達到片狀切屑。
  4. 銑刀設計螺旋方式不同也可以達到片狀切屑。
  5. 銑刀設計在刀口幾何上,如OD1與OD2地不同也可以達到片狀切屑。
  6. 銑刀在螺旋溝底經過設計也可以達到片狀切屑。
  7. 在切割工件利用控制加工參數 也可以達到片狀切屑(如主軸轉述快慢,轉角設定,近幾快慢,切割深度等相關條件)。
  8. 複合材料切割時,要達到片狀切屑,這跟複合材料特性有相對關係 ,對應加工材料採用不同的加工方式確保斷屑可靠性。
  9. 利用在工件表面上的預先開槽的方法,切出的切屑形成薄弱截面,從而折斷保證了可靠的斷屑,又不影響工件已 加工表面的粗糙度。即使加工韌性較大的材料時,斷屑效果也很好。
  10. 利用斷屑器或斷屑裝置。

Selections and types of End Mills

There are many kinds of end mills, which with wide range of applications.
It can be divided into the following three categories:

  1. Thimble cutter for machining plane.
  2. Carbide cutter for working grooves.
  3. Cutters for face milling.

The general specifications of end mills have been standardized, and they are usually produced by professional tool manufacturers. We introduce some popular types of end mills and their applications.

Cylindrical cutter

It is generally whole made with high-speed steel. Spiral cutting edges are scattered on the cylindrical surface, there is no sub-cutting edges. Spiral cutter is gradually cut from the work piece during machining, hence the cutting process is more stable , used on a horizontal milling machine to work the narrow plane which width is less than the cutter length.

Face Milling Cutter

Main cutting edges are scattered on the cylindrical or conical surface, the end cutting edge mostly are sub cutting edges. The cutter axis is perpendicular to the surface of work piece. Tooth material can be divided into high-speed steel and carbide, which are generally made into multi-system sets of tipped tooth structure, body material is 40Cr. Face milling cutter id mainly used in processing the plane and plate of vertical or horizontal milling machine, especially for the larger plane processing, the face milling cutter with main angle 90 ° can machine the plate face of wider bottom. Face milling cutter works the plane with more teeth and the deputy cutting edges of modifying may make the work face less rough so that it can have larger amount of the cutting, higher productivity, and the wide range of applications.

End Mills

It is the most popular one in CNC milling cutter. Its structure, the cutting edge of the cylindrical is the main cutting edge, and side surface of the distribution is sub-cutting edges. The main cutting edge is generally helical, so that it can increase cutting stability and improve the processing accuracy. Regarding ordinary end mills, there is no cutting edge in the center, so it cannot do axial feed during process. The end edge is mainly used for processing the side perpendicular to the basal plane.
End mills are most used for machining grooves, step surface and forming a surface by mold processing .. There are large helix angle rough end mills, corn cutters, and carbide waved-edge milling cutter, their bigger diameter can use a large amount of feed and increase productivity.

Tri-face milling cutters

It can be divided into straight-tooth edge and stagger-tooth tri-face milling, used on the plane of horizontal milling machine and at one or two runs through the end of the shallow trench. In addition to the circumference of the main cutting edge, the sides also with sub-cutting edge, which may improve the cutting conditions and increase the efficiency, reduce the surface roughness. The width and dimension are changed after grinding, the brazed tri-face milling cutters may resolve this problem.

Saw blade cutter

Saw blade cutter itself is very thin, teeth only on the rim of cutter, used to cut the work piece and the narrow slots. To avoid cutter folder, its thickness is thinning from the edge to the center, forming the vice declination on both sides.

Keyway cutter

The shape is similar to end mills. The difference is that there are only two spiral edges on the rim, its blade extends to the center, looks like end mills and also drill bit. While milling side barrier of the keyway, you can make the right amount of axial feed. To be used for processing round closed keyway and use it to processing, for repeatedly vertical and horizontal feed in order to complete the keyway machining.

Cutting Tools-Cutting Tools - definition and types of hard metal and difficult material

  1. Hard Material:
    Generally it means higher hardness of the steel material which can be cut, such as alloy steel, die steel. . . etc.
    Applicable to the cutters with coating, such as: TiAlN, TiN.
  2. Difficult material:
    It means the difficult-to-cut work piece, such as nickel-based alloys, stainless steel, etc.
    Stainless steel is applicable to the cutting tools with coating like TiALN.
    CBN tools is suitable to cut nickel-based alloy.
  3. Soft material:
    It means easy-to-cut cutting materials, such as aluminum, aluminum-magnesium alloy, low carbon steel, etc.
    Aluminum material is applicable to cutting tools of uncoated, containing cobalt, and high helix angle.

Aluminum material is also applicable to carbide cutter.

A variety of different work materials are cut bycutting tools of different materials. However, there are lots of cutting parameters, not only material, nature, shape, and feed, etc, but also manufacturers have lots of experience and information. For those materials which are less usage or used in specific areas, the related information is less, due to less market demand and few makers’ reference data, the failure rate will be higher, so users think this material is difficult to process.

For example, aerospace materials of nickel-based super alloy INCO718 738 is well-known as very difficult work material, the general comment is” the tool is very loss."

金屬鏡面加工 - part -

上一篇介紹去除材料方式的面加工後,本篇介紹無切削方式的鏡面加工。

無切削方式

常見加工為滾壓加工,是一種無切屑加工,在常溫下利用金屬的塑性變形,使工件表面的微觀不平度輾平從而達到改變表層結構、機械特性、形狀和尺寸的目的。因此這種方法可同時達到光整加工及強化兩種目的,是磨削、車削等機械加工無法做到且無切削加工技術安全、方便,能精確控制精度,滾壓後的表層金屬纖維完整。

在滾壓加工中常使用刀具為擠光刀,利用擠光刀機械擠壓的原理,獲得光潔如鏡的金屬表面的一種機械加工方法。擠壓刀加工是一種無切屑加工,在常溫下利用金屬的塑性變形,使工件表面的微觀不 平度輾平從而達到改變表層結構、機械特性、形狀和尺寸的目的。因此這種方法可同時達到光整加工及強化兩種目的,是磨削無法做到的。

滾壓加工原理:它是一種壓力光整加工,是利用金屬在常溫狀態的冷塑性特點,利用滾壓工具對工件表面施加一定的壓力,使工件表層金屬產生塑性流動,填入到原始殘留的低 凹波谷中,而達到工件表面粗糙值降低。由於被滾壓的表層金屬塑性變形,使表層組織冷硬化和晶粒變細,形成緻密的纖維狀,並形成殘餘應力層,硬度和強度提 高,從而改善了工件表面的耐磨性、耐蝕性和配合性。滾壓是一種無切削的塑性加工方法。

News-How do end mills choose and judge working conditions?

In recent years, machining center spindle is more and more speedy. For fitting the requirement of high speed machining on high hardness and strength materials and also prolonging mold life, the cutting tools advance its technology accordingly.

According to the processing demand, we will select the appropriate tool in accordance with the following recommendations:

  1. Basic cutting material of work piece, material properties, conditions, and manufacture processes….

    For example: customers’ demand about size, tolerance range, result up to mirror face, corner without joint point of tool exchange, cutting path of NC program, applications, and related issues.

  2. To clarify different material of cutting tools (like difference of hardness and strength…)

    Approx. types of cutters: single crystal diamond cutting tools, PCDs contenting CO diamond cutting tools, PCD containing Si diamond tools, PCBN cutting tools, metal porcelain cutters, tungsten carbide tools, HSS cutting tools, general steel cutters. Select proper cutting tools according to work piece.

  3. According to the special requirements of the work piece shape (for example: deep groove surface of work piece ...)

    Generally based around the shape, surface tensile, surface rotation, ball rounded shape, conic, cylindrical curve shape, and other relevant conditions of work piece to choose the shape of end mills. The neck types of end mills are divided into standard, long-neck, and cone-neck. Select cutters according to the machining depth of the work piece, shape, appearance, processing objects, crude/middle/fine three milling paths, and other related conditions. Long-neck and cone-neck types can process deep machining, it should take into account about the interference angle during selection in both .., Compared with the long-neck type, the high rigidity of the cone neck type milling cutter may promote cutting conditions and achieve better machining accuracy, you should choose cone-neck type end mills.

  4. According to the machining accuracy and delicate face of work piece to select different ball head accuracy and smooth edge end mills.

    The arc accuracy of ball end mills is typically ± 5μm; there are also ± 2 ~ 3μm high-precision end mills available for high-precision processing.

  5. According to the kinds and the hardness of the work piece to select the coating types of tools.

    BW TiALN coating is suitable for machining carbon steel and hardness below HRC40 of work piece; Nano titanium aluminum nitride film-NanoTiAlN coating is for alloy steel S, tool steel, and HRC50 work piece; BW TiALN + PLCcoating. Is good for higher hardness, hard alloy material of work piece.

  6. If the work pieces are hard-to-cut, and special material, you should choose high hardness cutters like metal ceramic and diamond tool.

    For example: if cutting metal composite material, you should choose BW metal ceramic cutter or PCBN diamond tool to solve cutting problems because the material is with high nickel content.

金屬鏡面加工 - part1除材料方式

無論用何種金屬加工方法加工,在零件表面總會留下微細的凸凹不平的刀痕,出現交錯起伏的峰穀現象,粗加工後的表面用肉眼就能看到,精加工後的表面用放大鏡 或顯微鏡仍能觀察到。這就是零件加工後的表面粗糙度,過去稱為表面光潔度。鏡面加工一般是工件表面粗糙度<0.8um的表面時,稱為鏡面加工。

常見鏡面的機械加工方法有:

  1. 去除材料方式:磨削、研磨、拋光、電火花。
  2. 無切削方式(滾壓加工):滾壓(採用鏡面工具)、擠壓。

※去除材料方式

常見加工為鏡面切削,是採用運動精度及剛性高之工作母機及擁有平滑輪廓的鑽石刀具,依據母性原理從事切削加工,然後將金屬、各種結晶材料、塑膠等表面加工程鏡面的技術。利用本技術加工而成之鏡面和以往利用磨粒加工之鏡面比較時,不僅能獲得較高的形狀精度,還具有在大波長範圍內對於反射率或雷射光的耐熱損傷性也很高,同時加工成本低等特色。

由於金剛石易與鐵族金屬發生化學反應,因此不適合加工淬硬鋼等工件材料,僅局限於加工非電解鍍鎳等非鐵金屬。但近年來,由於採用超聲波橢圓振動切削的加工機床性能的改進,單晶鑽石刀具也能用於淬硬鋼等鐵族金屬的鏡面加工。 鑽石是硬度最高、導熱性能最佳的刀具材料,在難加工材料的切削加工、幹式和半幹式切削加工中刀具有很長的使用壽命且鑽石刀具能獲得非常鋒利而無凹凸鋸齒的切削刃。因聚晶金剛石粒子間的結合強度弱于單晶金剛石,因此刃磨後的切削刃也會產生晶介面的凹凸和粒子脫落現象,故常使用刀具為單晶鑽石刀具。單晶鑽石切削刀具主要用於非球面透鏡、衍射光柵高精度光學元件的加工。

tool-90° Step Drill

Step drill, the related accuracy in manufacture process is the most important factor for cutting quality. If the precision isn’t controlled well, it will cause hole too rough and even caused reject of work piece. Not only geometry, specification, accuracy, and surface quality, but also the drill volume are important points for the cutting quality of step drill.

During drill process, if the chip groove isn’t well-produced, it would happen wall friction, extrusion, brushed and scratches on its surface. It will cause the bad quality of working surface and obstruction, drill bit stuck, and even broken the drill bit.

銑床精度與校正-part1銑床精度介紹

銑床在加工時,無論是刀具或是機器上的機件都會有複雜的交變應力,銑床於使用一段時間之後,或許因為機器本身穩固性鬆動,或許因為機件磨損或變形而使其精密度產生偏差,舉例來說:刀桿夾持長度及偏擺太多,原兩刃的刀其實只有1刃在切削,等於刀具使用的時效,只剩1/2而已;夾持精度越高代表刀具在尾端擺動量越小,也因此使用者可輕易達到工件所要求之精度或面粗度;另外,主軸偏擺會產生離心力會導致刀具在加工時,機台會晃動外,只用到單邊進行銑削造成刀具會磨損的嚴重或工件損壞,而轉速進給也會使刀具磨損。因此,機器經過一段時間的使用之後,就必須實施所謂的定期保養,定期保養校正可以確保銑床的精度及加工的品質,有高品質的機器,才能加工出高品質的工件。

  1. 銑床水平校正
    銑床的水平度不足,銑床操作時容易產生震動,並且銑床的床台也容易因受力不平均而產生變形。
  2. 銑床床台進給精度校正
    床台即需不停的移動以達到切削進給的目的,因此,銑床經過一段時間的使用之後,床台進給機構的配合面會有或多或少的磨損,使床台進給機構的配合面間產生鬆動或是其水平度或垂直度產生偏差。因此,床台進給的平行度、垂直度等需定期的檢驗及調整,才能確保銑床加工的精確度。
  3. 銑床主軸的偏轉度校正
    銑床在實際加工時,或因為銑床主軸偏心,或因為銑刀安裝偏差,銑刀轉動時,有產生偏轉的現象,銑刀如果產生偏轉,則銑床將大大的降低了加工的效率,因此,銑刀轉動時,其同心度是很重要的。銑床主軸正直度是影響銑刀偏轉的最重要因素,所以銑床需定期檢驗主軸旋轉的同心度,如果發現機器之主軸有偏轉情形,必須給予校正,以確保機器的加工效能。
  4. 銑床床台進給刻度環校正
    銑床加工的工件都有一定的尺寸標準,銑床加工控制尺寸的方法是應用銑床進給刻度環,如果銑床進給刻度環有鬆脫或磨損時,將導致工件加工尺寸控制不準確的結果。所以銑床進給刻度環必須經常調整,使床台進給機構之間隙能保持最小的誤差值,以確保銑床加工尺寸有效的控制。
