Leistritz’s CNC keyseaters are well suited for cutting small keys, yet heavy duty enough for huge keyways, as large as 7 inches wide, the company says. The CNC control is a valuable time saving device and can optimize the cutting parameters through fully flexible programming of feed rates and cutting speeds, as well as variable depths, if required. The CNC also allows the addition of a rotary table to produce helical grooves for special applications or multiple grooves within a single bore.
The company has also developed keyseaters with linear motors to make full use of modern cutting tool materials, including carbide to cut keyways in already hardened workpieces. The linear motor systems produce the high cutting speeds required to match that needed by the tooling and to shorten the cycle times for a production environment.
With machine strokes up to 60 inches, these machines can cut a variety of grooves in steels previously unthought of with little investment in both tooling and capital.
