Guidelines for Safe Use of Drilling Machines
A drilling machine is primarily used in Design & technology for accurate drilling of holes. Mortising can be carried out on this machine with the aid of various attachments.
A drilling machine consists of a base that supports a column that in turn supports a table. Work can be supported on the table with a vice or hold down clamps, or the table can be swiveled out of the way to allow tall work to be supported directly on the base.
The motor turns the spindle at a speed controlled by a series of stepped pulleys. The spindles holds a drill chuck to hold cutting tools (twists drills, forstener bits, spade bits, hole saws etc.). The quill is moved up and down with a lever or capstan wheel.
