繼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。

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.

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。

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.

BW-90° Step Drill	General-90° Step Drill

General step drill doesn’t grind a ramp edge in the step part, BW designs a ramp in the step part of drill to make chip removal easier, and also reduce the friction heat caused by the accumulated chips. The first and the second steps are vertical, so it is difficult to cut a gap in these parts during manufacture.
