鎢鋼圓鋸片是木製品加工最常用的刀具，木材是一種有纖維絲地天然資源、木料又分為有直絲與橫絲，目前合板會把直絲與橫絲交互編織做成三合板，刀具接近木料時，直紋木料就不易有毛邊，因為是直紋木料與刀具切割時成直線，所以切割不會有毛邊，但是橫紋木料與切割刀具成90度切割，木料纖維會因刀具偏擺、刀具鈍化、加工參數不正確等相關問題，而出現木料毛邊，其切割會毛邊或粗糙不外乎鋸片本身刃銳利度不夠、變形、齒形對應不當、齒數問題、機台操作參數不當、機台本身精準度…，對應不同加工材質硬度特性及切割要求在鋸片選擇上也是很重要，所以切割木料與切割金屬、塑膠、高硬度材料等材料，在刀具設計就會因客戶需求而做修正處理，當然也包括木材料的不同做調整生產刀具。

在切削加工中，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…）。

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

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

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.
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.
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.

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:

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.

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.

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.

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.

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.

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：

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

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.
