What component removes chips from the machine using a rotating shaft with a helical blade?

The chip auger is specifically designed to remove chips from a machine using a rotating shaft equipped with a helical blade. This design allows the chip auger to effectively convey metal chips away from the cutting area during machining operations. As the helical blade rotates, it transports the chips along the shaft, which helps to keep the work area clean and prevents the chips from interfering with the machining process.

In contrast, the other options do not fulfill this specific function. A chip guard serves to protect operators from flying debris but does not actively remove chips. The tool holder is responsible for securely holding cutting tools in place during machining activities but has no role in chip removal. Lastly, a worktable provides a surface for securing the workpiece during machining but also does not contribute to chip removal. Thus, the chip auger is the correct answer because it is the component tailored to efficiently handle chip removal through its rotating mechanism.
