Electroplated Diamond tools

Electroplated Diamond tools

This type of CBN cutter is specialized for grinding glass parts. The controller should have pecking function to avoid bad chip removal, which is related to CBN particles since the particle size is in proportion to the roughness of surface. We should say “grinding glass” instead of “cutting glass.”The spindle deflection will influence the grinding accuracy. Grinding is based on the consideration of smoothness, flatness, and parallelism. Press the surface of glass slowly and grind it by using abrasive. It is hard to control the smoothness, flatness, and parallelism under speedy cutting.

Grinding can be divided into coarse and fine grinding (fine grinding can be told as polishing). Coarse grinding is with bigger particles, it may increase the efficiency to get rid of thickness. When it reaches predetermined thickness, use find grinding to polish the surface of light transmittance and clarity. This way can restore the clarity of glass surface and light transmission.

常見切削刀具材料

常見切削刀具材料

刀具材料性能的優劣是影響加工表面品質 、切削加工效率、刀具壽命的基本因素 。切削加工時,直接擔負切削工作的是刀具的切削部分。刀具切削性能的好壞大 多取決於構成刀具切削部分的材料、切削部分的幾何參數 及刀具結構的選擇和設計是否合理。切削加工生產率和刀具耐用度的高低、刀具消耗和加工成本的多少、加工精度和 表面品質的優劣等等,在很大程度上都取決於刀具材料的合理選擇

刀具材料應具備的性能:

  1. 較高的硬度和耐磨性;
  2. 足夠的強度和韌度;
  3. 較高的耐熱性;
  4. 良好的技術性和經濟性。

常用的刀具材料:

  • 碳素工具鋼:
    含碳量較高的優質鋼(含碳量為0.7%~1.2%,如T10A等),淬 火後硬度較高、價廉,但耐熱性較差。
  • 合金工具鋼刀具材料:
    在碳素工具鋼中加入少量的Cr、W、Mn、Si等元素 ,形成 (如 9SiCr等),可適當減少熱處理變形和提高耐熱性。常用來製造一些切削速度不高的手工工具,如銼刀、鋸 條、鉸刀等,較少用於製造其它刀具。
  • 高速鋼刀具材料:
    它是含W、Cr、V等合金元素較多的合金工具鋼。普通高 速鋼:如W18Cr4V,廣泛地用於製造形狀較為複雜的各種刀具,如麻花鑽、銑刀、拉刀、齒輪刀具和其它成形刀具等。
  • 硬質合金刀具材料:
    硬質合金是由難熔金屬碳化物(如WC、TiC、TaC、NbC 等)和金屬粘結劑(如Co、Ni等)粉末經粉末冶金的方法製成。它的硬度高、耐磨性好、耐熱性高,允許的切削速度比高 速鋼高數倍,但其強度和韌度均較高速鋼低,工藝性也不如高速鋼。因此常製成各種型式的刀片,焊接或機械夾固在車 刀、刨刀、端銑刀等的刀柄(刀體)上使用。
  • 陶瓷或金屬陶瓷刀具材料:
    Al 2O3基和Si3N4基兩類。以氧化鋁或以氮化 矽為基體再添加少量金屬,在高溫下燒結而成的一種刀具材料。有很高的硬度與耐磨性,常溫硬度達91~95HRC; 有很 高的耐熱性,在1200℃高溫下硬度為80HRC;而且高溫條件下抗彎強度、韌性降低極少; 有很高的化學穩定性,陶瓷與 金屬親和力小,高溫抗氧化性能好,即使在熔化溫度下也不與鋼相互作用。因而刀具的粘結、擴散、氧化磨損較少;有 較低的摩擦係數,切屑不易粘刀,不易產生積屑瘤。
  • 超硬(superhard)刀具材料 :
    它包括天然金剛石、聚晶金剛石和聚晶立方 氮化硼3種
    • 天然金剛石:自然界最硬的材料,其硬度範圍在HK8 000~12 000 (HK,Knoop硬度,單位為kgf/mm2),耐熱性為700~800℃。天然金剛石的耐磨性極好,但價格昂貴,主要用於加工精度 和表面粗糙度要求極高的零件,如加工磁片、鐳射反射鏡、感光鼓、多面鏡等。其主要缺點是與鐵族材料有親和作用, 不宜加工鋼和鑄鐵。
    • 聚晶金剛石(PCD):碳的同素異形體,在高溫、高壓下由石墨轉化而 成,是目前人工製造出的最堅硬物質。硬度極高,耐磨性好,切削刃口鋒利,刃部表面摩擦係數較小,不易產生粘結或 積屑瘤,可在大部分場合可替代天然金剛石,可製成各種車刀、鏜刀、銑刀等刀片。
    • 立方氮化硼(CBN):立方氮化硼(CBN)是一種人工合成的新型刀具材料,它由六方氮化硼在高溫、高壓下加入催化劑轉化而 成。有很高的硬度及耐磨性,熱穩定性好,化學惰性大,與鐵系金屬在1300℃時不易起化學反應,導熱性好,摩擦係數 低。

切削刀具製造流程

切削刀具製造流程

切削刀具的製造過程 :

切削刀具製造流程

碳化鎢粉末(WC、TiC)微米級粉末為主要成分,以鈷(Co)或鎳(Ni)、鉬(Mo)為粘結劑,原料驗收秤量配合後混和。混和後造粒把原料粉末放入模具里衝壓成型,使其具備近似粉筆的硬度。在1400°的溫度下真空爐或氫氣還原爐中燒結而成硬質合金。再使用金剛石砂輪進行研磨切削加工,使其成為希望的形狀及刃口幾何,再鍍層鍍層具有強大的防護、耐酸、耐氧化抗磨耗等特性,可大幅增加刀具的壽命,使工件表面品質提昇,增進製造效率與品質優良率。

鎢鋼碳化鎢的俗稱,英文是Tungsten Carbide

當然除了碳跟鎢之外還加了鈷以及其他的合金材料以增加他的機械性能,鎢鋼的硬度很高,所以常用來做為切削刀具的材質。鎢鋼的機械性質主要由兩個部分影響,第一個部分是鈷的含量,含量越高硬度越低,但是韌性較好,另一個是粉末的粒徑,粒徑越小越耐磨,但是成本較高。

※熱等靜壓或熱間等方加壓 (hot isostatic pressing,簡稱HIP)

是一種集高溫、高壓於一體的生產技術,加熱溫度通常為1000 ~2000℃,通過以密閉容器中的高壓惰性氣體或氮氣為傳壓介質,工作壓力可達200MPa。在高溫高壓的共同作用下,被加工件的各向均衡受壓。故加工產品的密度高、均勻性好、性能優異。同時該技術具有生產週期短、工序少、能耗低、材料損耗小等特點。

Diamond cutter in grooving floors


tool-PCD cutter in grooving 

floors
Polycrystalline diamond (PCD) complex material is made by mixing fine diamond

particles of micron grade, Co, Ni, and other metal powder under high pressure and high

temperature, which is a new advanced cutter material sintered on WC substrate. There are many

superior benefits of PCD complex, not only high hardness, wear resistance, thermal conductivity,

low friction, low thermal expansion, but also with excellent strength and toughness. It has

conductivity, so it can be cut by wire electrical discharging machine into required cutting

edge. Then we weld the blade on the cutter body and grind it into PCD cutter.

刀具磨耗與壽命


刀具磨耗與壽命
刀具磨耗在切削時熱和摩擦所產生的物理作用和化學作用的綜合結果。刀具由開始 切削達到刀具壽命依據以前所經過的切削時間稱為刀具壽命,刀具壽命依據一般採用刀具磨損量的某個預定值,也可以把某一現象的出現作為判斷依據,如振動激化、加工表面粗糙度惡化,斷屑不良和崩刃等。達到刀具壽命後,應將刀具重磨、轉位或廢棄。切削過程中刀具的刀頭部位因不斷地受到很大的作用力、高溫和激烈的摩擦作用而磨損,等磨損到某一程度時刀具即無法再勝任原有的切削功能,稱此段堪用的時間稱為刀具總壽命。
生產中 常根據加工條件,按最低生產成本或最高生產率原則,來確定刀具壽命和擬定工時定額。影響刀具壽命因素很多且複雜,

其中可判斷影響主要因素:

  1. 刀具材料與工件材料之配合情形
  2. 切削速度
  3. 切削厚度
  4. 切削寬度
切削速度增加,可使工件加工時間縮短,且加工面精度較佳,但刀具的磨耗速率卻會增加,亦即刀具壽命會縮短。刀具壽命切削速度之間相互制約的經驗公式為
VTn = C
  • T:刀具實際使用的切削時間(min)
  • V:為切削速度(m/min)
  • N: 常數 (刀具材料、工件材料與切削條件有關)
  • C:常數 (指刀具壽命為一分鐘時的切削速度)

刀具的磨損包括磨耗和破損

1. 刀具破損通常是突然發生,產生的原因有:

  1. 刀具幾何形狀不當
  2. 切削負荷過大
  3. 顫動或振動的衝擊作用
  4. 切削溫度超過其高溫硬度的極限
  5. 刀具本身即存在微裂縫的瑕疵等

2.造成刀具磨耗的主要原因有:

  1. 熔著
  2. 刮除
  3. 擴散

常見刀具磨損

  1. 凹陷磨耗(Cater wear)
  2. 熱變形(Thermal deformation)
  3. 熱龜裂(Thermal cracking)
  4. 刀鼻磨耗(Nose wear)
  5. 深切凹口(Depth of cut notching)

刀具磨損過程

  1. 初期磨損:

    此階段磨損因刀具讓面微觀粗糙不瓶,於切削作用下微觀突起先被磨平,隨之讓面被磨出一磨損帶,此後壓力減少,磨損速度趨於穩定。
  2. 正常磨損:

    刀具讓面磨損寬度隨切削時間增長而均勻增加,磨損狀況較穩定,此階段為刀具加工之有效期,刀具應在此範圍內使用。
  3. 劇烈磨損:

    此階段刀具變鈍,切削力增大,切削溫度上升,刀具很快失去切削能力,刀具磨損達此階段時,刀具材料損耗過大,刀具使用時應盡量避免到此階段。

刀具鍍層-超硬薄膜被覆材

刀具鍍層-超硬薄膜被覆材

超硬薄膜被覆:

硬質合金表面以TiC,TiN,TiCN,Al2O3…等硬質陶瓷被覆數μm者,可以比WC系超硬合金更高的速度使用,也可比陶瓷更高的進刀量切削。其被覆方式有CVD法(化學蒸著法)及PVD法(物理蒸著法)。

刀具鍍層-超硬薄膜被覆材 刀具鍍層-超硬薄膜被覆材

被覆方式:

被覆法 CVD法(化學蒸著法) PVD法(物裡蒸著法)
介紹 利用氣體化學反應,以約1000°C左右的溫度被覆。 將被覆層的主要成分金屬蒸發離子化,與氣體反應而在負極處理的母材(約500°C左右)被覆TiN等方法。
優點 1.母材可以全面均一被覆。 2.由於處理溫度,所以被覆層和母材的密著強度高。
3.相異的被覆層可以很容易的僅以氣體切換
4.由於可以以大量地被覆處理,所以處理成本低。
1.處理溫度低,所以幾乎沒有熱變形
2.被覆粒子微細瑣已可已在銳利的刀尖直接被覆。
3.在被覆層壓縮應力作用,所以有利強度。
4.安全且無公害所已無需排氣處理設備
缺點 1.在接近母材表面易生成脫碳等變質層。
2.由於處理溫度高所以容易起尺寸變化及變形。
3.在被覆層容易產生聲熱應力,由於母材的種類伴隨著拉應力在表面發生龜裂。
4.由於生成HCl等,所以必須排氣處理。
1.母材與被覆層密著性小,所以於不適用大剪斷力作用處及要求大耐磨耗性之處。
2.迴轉不易所以必須賦與母材迴轉機構,對孔內部均一被覆也不易。
3.母材附加電壓的場合多,所以需要保持試料及裝配裕鍍,處理能力受限,很輕易地提高成本。

鍍層薄膜被覆材需求特性:

  1. 硬度
  2. 耐磨耗
  3. 那熔著性
  4. 耐氧化性
  5. 耐蝕性
  6. 韌性
  7. 疲勞強度
  8. 耐熱疲勞性
  9. 耐剝離

刀具常見鍍層薄膜特性應用:

鍍層如同刀具之盔甲,具有強大的防護、耐酸、耐氧化抗磨耗等特性,可大幅增加刀具的壽命,使工件表面品質提昇,增進製造效率與品質優良率。

塗層處理必須適材適性,才能在使用的條件件下發揮高性能,故要了解各鍍層特性,然後再應用於切削刀具上達到更好效果。
