Blanchard Grinding for Large & Small Metal Parts

Also known as rotary surface grinding, Blanchard grinding is used to remove excess material from large surface areas. With its ability to deliver high removal rates, this technique is a preferred choice for customers seeking quick results. Our skilled team can also effectively grind smaller parts by grouping them together and processing multiple workpieces at once, allowing for increased part consistency and faster throughput on high quantity projects.

At Petersen Precision, our Blanchard grinding expertise enables us to maintain tolerances of ±0.001” and surface finishes up to 64 RMS, depending on the size of the material being ground. To ensure optimal quality and efficiency for even the highest production runs, all fixtures and tooling used in our surface grinding processes are designed and fabricated in-house.

What are the Advantages of Blanchard Grinding with Petersen Precision?

The speed, consistency, and versatility of Blanchard grinding make it a highly effective way to remove high amounts of material from different sized workpieces. The repetitive motion of Blanchard grinding creates a unique swirling pattern on part surfaces. Because of this, Blanchard grinding is sometimes used to provide a decorative finish for aesthetic purposes.

Additional benefits Blanchard grinding can provide to your project include:

  • Efficiency
  • Uniform surface finish
  • Fast throughput
  • Versatility
  • Cost-effectiveness
  • Large & small part capabilities

CNC Blanchard Grinding for Parts of All Shapes, Sizes, & Materials

Blanchard grinding is used to achieve a flat and uniform finish on large, medium, and small parts made from difficult-to-machine materials. We work with a variety of ferrous and non-ferrous metals, including:

  • Aluminum
  • Stainless steel
  • Bronze
  • High strength steels
  • Tool steels
  • Titanium
  • Copper
  • and more

Differences Between Blanchard Grinding & Precision Surface Grinding

Both processes are used to achieve accuracy when grinding flat surfaces, but they differ in terms of their tolerance capabilities. While blanchard grinding is the most efficient method for removing large amounts of material in rough finishing applications, precision surface grinding is typically used to achieve precise dimensions and a high level of surface finish. Where Blanchard grinding is usually performed on larger pieces of metal, precision grinding is often used for smaller, more intricate parts. Both precision grinding and Blanchard grinding can be used to create high quality metal parts for a variety of industries, including aerospace, medical, automotive, and more.
