The rotary motion of the magnetic chuck allows work to be loaded in a full circle so that there are no end pieces. This combined with the grinding pressures exerted by the grinding spindle produce the "Blanchard Grind". This combination produces finished work to flatness and size across the magnetic chuck that is to extremely close tolerances.

Blanchard grinding does not produce a very fine finish (approximately 64 RMS max surface finish) but as it is generally performed early on in the part production process surface ...
Grinding processes like double disk grinding and Blanchard grinding push parts into the leading edge(s) of their cutting wheels that does not have the averaging affect that the orbital motion cutting can obtain. Discover Materials Used with Precision Lapping Services
Also known as rotary surface grinding, the Blanchard technique involves the use of either magnets or specially designed holders that secure the component and hold it in place. Machine operators pair this setup with the Blanchard grinding machine, which consists of a wheel that mounts on a vertical spindle.
Our Blanchard grinding is used to quickly remove stock from one side of a large part. There is a specific finish pattern left on surfaces that are Blanchard ground. This happens by the nature of the operation, and how the grinding tools moves across the surface. Due to the design and operation of a Blanchard grinding machine, it will grind ...

Blanchard Grinding We use Blanchard grinding in finishing large portions of plate stock, die blocks, rotatory table and stampings. It is a process that arose and was named after the Blanchard Machine Company of Cambridge. This system provides a quick and uniquely cost-effective method for cutting away large metal shards over a large surface area.
Blanchard Grinding a 96" corner to corner part on our 84". The part is so flat the operator has a hard time lifting it off the chuck.
Rotary surface grinding is often referred to as Blanchard grinding because it removes large amounts of stock quickly and efficiently. While it is not usually referred to as a precision grinding process, it is an excellent surface finishing method often used for large pieces of material or parts.
Grinding Processes provides a comprehensive overview of the various types of grinding used in modern manufacturing environments. Surface, cylindrical, centerless, and internal grinding processes are commonly used for workpieces of various shapes. Surface grinding is further distinguished by whether the table is rotary or reciprocating, and whether the spindle is …
Blanchard grinding available up to 154" diameter. ... Pieces with thickness tolerances better than +/- .002 depending on size may require additional processing, usually in the form of reciprocal grinding. Avoid specifying tight tolerances unless they are absolutely necessary.
Inside diameter grinding, also called as internal grinding, is used for grinding the inner diameter of tubular object. Workpiece or object will have already drilled hole and internal grinding process will be performed to finish the inner surface of workpiece with the help of small grinding wheel rotating at higher revolution per minute.
With Blanchard grinding technology, parts are mounted to a rotating chuck and processed by counter-rotating grinding wheel segments. This produces a unique spiral surface finish suitable for a wide variety of precision applications. The process of Blanchard grinding removes material from one side of the part at a time.
Blanchard grinding, also known as Rotary Surface Grinding, was developed by the Blanchard Machine Company in the 1900s. It is a far more economical process than precision grinding. As a result, Blanchard grinding is best suited for large pieces of material, and is typically not used to grind anything to a tolerance of less than 0.001".

ME 338: Manufacturing Processes II Instructor: Ramesh Singh; Notes: Profs. Singh/Melkote/Colton Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2.
Thickness, Parallelism and Flatness – Definitions. Plate thickness: the distance between two surfaces of a part (commonly the top and bottom) with a deviation tolerance specified (ex. 2.307" +/-0.0010"). This distance is most commonly measured by using precision micrometers.. Plate parallelism: parallelism is related to thickness. The difference between the thickest and …
