Machining functions such as cutting, welding, grinding, deburring, milling and polishing have historically represented a relatively low percentage of robotic applications. In 2018, for example, welding and soldering, dispensing and processing (cutting, grinding, de-burring, milling and polishing) accounted for only 25% of total applications of industrial robots.

He's not saying that the machines magically become more capable of grinding an endmill to size & form in Dc 12.0000mm than they are capable of grinding to sise & form in Dc 12.7000mm. He's saying that those companies don't even bother to offer them in the Dc 12.7000 sizes. Back on topic.

Metal cutting, grinding, drilling, boring, and other tasks are all part of machining. And as these activities are all "metal-on-metal," at some point, something must give. This "give" comes in the form of tool wear, where regular operation means that tools will lose surface, sharpness, and temper over time.

Machines in which grinding wheels are fitted and grinding is done, such machines are called grinding machines. On the basis of their function, they can be divided into two parts. Ordinary grinding machines are widely used. These are called rough or snagging grinders. The following types of grinders are included in this category.

A grinding machine, often shortened to grinder, is one of power tools or machine tools used for grinding.It is a type of machining using an abrasive wheel as the cutting tool.Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation.. Grinding is used to finish workpieces that must show high surface quality (e.g., low surface …

When batch CNC lathes process medium and small batches of parts on non-CNC grinders, due to various reasons, the pure cutting time only accounts for 10%-30% of the actual working hours. This ratio may rise to 70% to 80% when machining on a multi-process centralized CNC grinding machine such as a grinding machining
