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).
! B/ Y8 K" X. i- O' z; d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的,，因為機床多使用磁性轉(zhuǎn)盤夾持。當然也可以加工非鐵磁類產(chǎn)品甚至塑料件,，然而產(chǎn)能低,、費用高（因為上下料比用磁性浪費很多時間）。% V- c! P! j5 s& R0 s# ^

4 X) q" D& ]  [8 TBlanchard 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.

5 A+ J3 I; b- |6 [: l+ cIn 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.  a- R9 \  E" ]
布蘭查德磨床的砂輪軸垂直布置,，旋轉(zhuǎn)方向和磁性吸盤方向相反,。磨削前,，表面應相對平整，沒有異常凸起,。該加工方法可以保證公差范圍在千分之一英寸（25微米）,，平面度亦是如此。然而公差和被加工的材料和形狀有很大關系,。通過（合理地）設計和使用該類設備,，各種工件可獲得一致的尺寸，從而使大批量生產(chǎn)受益,。4 N/ d! z2 @- b6 O0 _1 F
