The term “Blanchard Grinding” is to rotary surface grinding what Xerox is to photocopying. Rotary surface grinders use a lot more horsepower than other methods, removing a large amount of stock from one side of a part faster than other grinding methods. Furthermore, both the leading and trailing edges of the grinding wheel are in contact with the work piece, resulting in highly accurate, flat surfaces, perfect for mating parallel surfaces or if part-to-part tolerances are close.
The right size Blanchard grinder can handle very large projects like rotary tables, side plates or vacuum chambers, or when you need to cut out several smaller pieces with each part made the exact same thickness. You can also place multiple parts to be ground together, minimizing the per-unit finishing cost, such as resurfacing brake rotors or sharpening a group of stamping tools. As with any manufacturing process, you must consider how best to stretch your budget.
1. Contract out your Blanchard grinding services.
2. Buy your own machine from a Blanchard grinder company.
3. Service your grinder with Blanchard parts.
