Understanding Blanchard Grinding
Blanchard grinding, often referred to as surface grinding, utilizes a vertical spindle and rotary table machine for achieving precision in flatness and finishes. The term originates from the most common machines of this type made by Blanchard, but similar machines are also produced by other manufacturers. These machines are versatile and can handle a range of shapes, sizes, and materials.
The essence of Blanchard grinding is its ability to produce very accurate flat surfaces and fine finishes. The machine's design, with its vertical spindle and rotary table, allows for grinding a wide variety of materials. Through innovative fixturing techniques, these grinders can handle diverse shapes and sizes.
The grinding process involves a combination of the machine's capabilities and the operator's expertise. Factors such as load areas, configurations, feeds, speeds, and motor loads play a crucial role in achieving the desired results. For instance, optimal table loads vary based on the size of the machine, and achieving the right balance between table speed and downfeed rate is paramount.
In addition to the machine's capabilities, the choice of abrasive is critical. Abrasives, which do the actual cutting, are typically made of either Aluminum Oxide or Silicon Carbide. The selection of the abrasive grain is determined by the material being ground, with different grains offering varying properties of hardness, friability, and sharpness. The bond, which holds the abrasive grain in the wheel, can be either vitrified or resin.
In the realm of Blanchard grinding, understanding the intricacies of the process and the machine's capabilities is essential for achieving precision and efficiency. Whether you're grinding soft steels or hard materials like tool steels and stainless steel, the right combination of machine settings and abrasive selection will ensure optimal results.

Frequently Asked Blanchard Grinding Questions:
What is Blanchard grinding? Blanchard grinding, a technique developed in the early 1900s by the Blanchard Machine Company, is a form of rotary surface grinding. Unlike other grinding methods, Blanchard grinding uses a vertical spindle combined with a rotary table, making it distinctively efficient. The process is known for its ability to remove significant amounts of material quickly while leaving behind a unique cross-hatched pattern. This pattern not only adds to the aesthetic appeal but also enhances the functionality of the surface, ensuring better adhesion for coatings or paints.
How does Blanchard grinding differ from precision grinding? The primary distinction between Blanchard and precision grinding lies in their objectives and the materials they handle. Blanchard grinding is the go-to method for materials with larger surface areas. It emphasizes rapid stock removal, especially when one side of a material needs to be ground down. Precision grinding, as the name suggests, is all about finesse. It's tailored for materials with smaller surfaces and aims to achieve a superior, mirror-like finish with high parallelism. While Blanchard is about bulk and speed, precision grinding is about detail and accuracy.
What's the tolerance level for Blanchard grinding? In the world of grinding, tolerance levels dictate the precision and accuracy of the final product. The industry standard for Blanchard grinding is a tolerance of up to 0.001â€. However, at Grindmasters Inc., we're not just about meeting standards; we're about setting them. We consistently push for even tighter tolerances, often achieving results that surpass client expectations. Why? Because in our line of work, every thousandth of an inch can make a difference, ensuring that the final product is not just good, but exceptional.
How much material can Blanchard grinding remove? Blanchard grinding is renowned for its material removal capabilities. At Grindmasters Inc., our machines and expertise allow us to remove between 0.25 to 0.5 inches from steel in a single pass. This means projects that might take days using other methods can be completed in hours with Blanchard grinding. And here's the kicker: even with such rapid removal, we never compromise on the quality of the finish. Our clients get a quick turnaround without any drop in the excellence they've come to expect from us.
