Form drilling system

Schwanog PWP form drilling systems with insertable form tools improve cycle times for users of sliding- and fixed-head turning centers and multi-spindle turning centers.

The PWP insertable form drill system consists of a holder, retaining screw, and an insert that is individually ground according to the customer’s drawing. During tool changeover, the insert holder stays untouched in the machine, resulting in the center height remaining unchanged. These form drills can hold the process safe within a minimum tolerance of ±0.03mm.

Complementing the PWP system is the PWP-D system, which offers wider inserts, achieving a maximum drill diameter of 28mm. Both form drill systems are available in various carbide grades.

The PWP uses a V-style design for mounting in the holder. The PWP-D features a square design, allowing it to hold the diameter across the entire drill depth, with widths of 18mm, 23mm, or 28mm.

Reduction in setup time is one advantage of the system. With solid carbide drills, when the tool is worn, the entire drill is removed for re-sharpening, and then it must be brought back on center, resulting in machine downtime. With the insertable tool, users have easy access to the retaining screw in the machine to open it up, remove the insert, replace it with a new one, and lock it down. The holder is not touched, resulting in increased machine uptime and reduced setup time.
