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。

高效的切削技術和刀具已成為汽車製造業的基礎工藝和關鍵技術。高速切削、幹切削、硬切削等新的切削工藝正在改變傳統的加工工藝，顯現出強大的影響力。汽車工業是專用刀具應用繁多的行業，目前汽車製造業的機械加工所使用的刀具主要是超硬刀具材料，汽車工業一般常見加工如下:

在汽車零件加工方面

曲軸的粗加工

曲軸的金屬加工工藝流程為：銑端面、定總長、鑽品質中心孔、車大小端外圓→銑主軸頸及軸肩→銑連杆頸及軸肩→車拉主軸頸及沉槽→車拉連杆頸及沉槽→槍鑽油 孔→清洗→圓角滾壓→法蘭鑽孔攻絲→精磨主軸頸（CBN）→精磨連杆頸（CBN）→斜切磨小端→斜切磨法蘭端→車滾止推面、銑鍵槽→動平衡→砂帶拋光主 軸、連杆及法蘭外徑→清洗、冷卻→檢測分類。

平面銑削的應用

可轉位面銑刀在現代汽車製造業中，平面銑削的應用極為普遍。選用高硬度、高強度的刀具材料，再進行適當塗層，是延長刀具壽命的首要措施。同時，改進刀具幾何形狀也是增加刀具壽命的重要手段，在汽車製造業中，鑄鐵的銑削加工是一個重要課題。包括灰鑄鐵、球墨鑄鐵和蠕墨鑄鐵在內的各種合金鑄鐵有著不同的加工特性，因此，對銑刀幾何角度的優化改進十分重要。

孔加工刀具

在孔加工中，目前仍大量使用高速鋼麻花鑽，但各企業之間在孔加工精度和加工效率方面已逐漸拉開差距。高速切削鑽頭的材料以陶瓷塗層硬質合金為主，在各種塗層鑽頭中，陶瓷塗層硬質合金鑽頭特別重視耐磨性、耐熱性及潤滑性，其塗層工藝也採取多層塗覆方式，如利用TiAlN、TiN、TiCN等複合氮化物形成複合塗層結構。鑽頭的切削正不斷高速化，隨著被加工材料的不同，切削速度已可分別達到200～300m/min。

今後的發展趨勢是，將普遍採用高速(超高速)乾式切削技術。採用超硬材料製作的各類刀具、複合 (組合)或各類高速切削刀具的結構設計與製造技術將成為刀具品種發展的主導技術。其中無屑加工工藝的搓、擠、滾壓成形類刀具的應用將會更加廣泛；超硬刀具材料發展會更快，應用領域會更加擴大。

燒結碳化物(碳化鎢、鎢鋼)有兩等級

一為純碳化物類及抗陷穴類。純碳化物只包含碳化物和鈷，強度及耐磨特性最好，任何其他物質加入均將減少其強度及耐磨性，通常用來切削鑄鐵及非鐵金屬材料。但純碳化物不耐高溫，在高熱下鋼屑易沾黏在刀面上，使刀面因擴散作用形成凹陷。而加入碳化鉭及碳化鈦之碳化物，因這兩成分熔點高於碳化鎢，故抗高溫性也相對提高，相對的強度及耐磨特性較純碳化物低。

PCD cutter brings high cutting efficiency and stable accuracy.

工件受刀具之切削後，內部產生了塑性變形，其塑性流動程度之大小直接影響了切屑的形態。一般切屑的基本形態有：不連續切屑、連續切屑和積屑刀口的連續切屑等3種。
