Slotting grinding is the most time-consuming and cost-intensive manufacturing process in the production of drills and end mills. With the development of grinding machines, the spindle power is increased and the shaft stroke is smaller. SGA developed slotted grinding wheels to meet the development of the industry. The requirements and make these high-efficiency grinding machines achieve better economic benefits are the wise choice for users.

The splitting tooth can reduce the width of the chisel or end mill chisel edge and reduce the stress used by the tool. In general, the 12V9 grinding wheel or the sharp edge 1V1/14V1 grinding wheel can be used for the edge grinding.

Grinding the back angle of the cutting edge of the tool reduces the contact area between the tool and the workpiece during drilling or milling. Typically, one or two back angles are ground on the end face. Two relief angles/gap can be made along the circumference; on some tools, radial clearance grinding is required. In general, an 11V9 cup wheel or a similarly shaped grinding wheel is used to grind the back angle.

For special tools, we can customize the tools to provide the best solution for our customers according to the size and application requirements provided by the customer.
