As reported by Modern Machine Shop in their article “When Grinding Is Like Turning,” high-speed machining using CNC milling machines involves taking fast, light cuts at high spindle speeds to achieve higher material-removal rates. Similarly, peel grinding aims to achieve high material-removal rates for cylindrical parts requiring outside-diameter (OD) grinding. Unlike traditional grinding, peel grinding uses fast grinding wheel speeds and relatively deep passes, thanks to its thin wheel and low grinding forces.
The advantages of peel grinding are leveraged to enhance machining capabilities. This high-speed grinding process, resembling single-point turning on a lathe, allows the grinding wheel to move in the X and Z axes, enabling the grinding of contours, different diameters, and other features on a workpiece. When combined with advanced grinding wheel technology and high-pressure straight-oil coolant delivery, peel grinding significantly improves material-removal rates, especially for challenging materials like carbide, ceramic, polycrystalline diamond, and glass.
Complete Grinding Solutions, a grinding shop in Springboro, Ohio, exemplifies the benefits of peel grinding. Founded by Beat Maurer and Raphael Obrecht, both former employees of Swiss grinding machine OEM Studer, the shop specializes in highly challenging, tight-toleranced grinding work. The shop’s flexible universal CNC grinding machines from Studer allow for a wide range of grinding operations, including ID/OD grinding, internal grinding of complex shapes, thread grinding, and out-of-round grinding.
Peel grinding has proven particularly advantageous for grinding exotic materials. For instance, Complete Grinding Solutions manufactures custom carbide arbors for ID grinding tools, benefiting from carbide’s rigidity and wear resistance. Peel grinding the outer diameter of a carbide arbor takes just a few minutes, compared to approximately 20 minutes using conventional grinding processes. This efficiency is crucial for the shop’s diverse customer base, which includes industries such as aerospace, automotive, medical, and renewable energy.
Similar innovative grinding techniques are adopted to deliver high-quality, precise machining solutions. Expertise in advanced grinding processes ensures optimal performance and durability of products, meeting the stringent demands of various industrial applications.
