現(xiàn)在有一40mm的板材 要加工到35  客戶的技術(shù)要求是blanchard gr  我們想用龍門(mén)銑床 可以嗎，加工出來(lái)的產(chǎn)品表面有什么不一樣  新人求解�。�

Blanchard grinding is used to quickly remove stock from one side of a large part. Typically, ferrous metals are subjected to the Blanchard grinding process, since the part is often held in place by a magnetic chuck as it is ground. It is, however, possible to use Blanchard grinding on non-ferrous metals and even plastics, but production rates tend to be lower and costs are higher (due to added setup time).
布蘭查德磨削法用于快速去除大（面積）零件的單側(cè)余量。最適典型的零件是鐵磁類(lèi)的，因?yàn)闄C(jī)床多使用磁性轉(zhuǎn)盤(pán)夾持。當(dāng)然也可以加工非鐵磁類(lèi)產(chǎn)品甚至塑料件，然而產(chǎn)能低、費(fèi)用高（因?yàn)樯舷铝媳扔么判岳速M(fèi)很多時(shí)間）。

Blanchard grinding leaves a specific finish pattern on surfaces, produced by the nature of the operation, and of the movement of grinding tools across the surface. Technically referred to as rotary surface grinding, the process is ideal for surfaces too large for disc grinding, such as plate stock, die blocks and rotary tables. Although it uses far more horsepower than other grinding services, turnaround time is much faster for certain parts; the process can be used simultaneously on multiple parts, as well, also leading to reduced production times and expense.
布蘭查德磨削法會(huì)在工件表面留下獨(dú)特的紋路，這是砂輪劃過(guò)工件表面時(shí)自然產(chǎn)生的（呵呵，擺線！�。。�。該技術(shù)使用了旋轉(zhuǎn)工作臺(tái)，因而工件比砂輪大也無(wú)妨，例如平板、模塊和轉(zhuǎn)臺(tái)零件。雖然這比一般的磨床需要高得多的功率，但是旋轉(zhuǎn)顯然更快（相較于傳統(tǒng)的直線進(jìn)給）。而且多個(gè)零件可以同步加工，這也進(jìn)一步降低了工時(shí)和成本。

0 s4 x% F; v8 a( i+ FIn a Blanchard grinding machine, the grinding wheel is mounted on a vertical spindle, and moves in a direction counter to the rotation of the magnetic chuck. Before grinding, surfaces should be relatively even, without any significant protrusions. The tolerances provided by Blanchard grinding machines can be as little as one-thousandth of an inch, with similar flatness. Tolerances, however, vary between materials and work pieces. Due to the design and operation of a Blanchard grinding machine, it will grind different work pieces to a uniform size, a benefit for extensive production runs.

Blanchard grinding gets its name from the Blanchard Machine Company, a specialist in rotary grinding machines. The process is an excellent choice for applications requiring high-production rates and moderate finish accuracy.
布蘭查德磨削法得名于布蘭查德機(jī)床公司，該公司是轉(zhuǎn)臺(tái)磨床的專(zhuān)家。該方法是中等精度高效率加工的優(yōu)選。
