Release of the SPX deep shoulder milling end mill series
May 31, 2007
Mitsubishi Materials Corporation has recently released another innovative tool, the SPX. This revolutionary cutter can be used to increase machining productivity of deep shoulder milling and slotting. The primary application area is the Die and Mould industry, however it can be effectively used in any application that requires high efficiency machining of deep shoulders and slots.
- Wavy Edge Geometry:
- The inserts used in the SPX have a wavy cutting edge design. This ensures that when the cutter is rotating, they form an overlapping pattern similar to a standard roughing end mill. The result of this geometry is a drastic reduction in cutting resistance and makes it possible to increase overall cutting conditions for improved efficiency. Additionally the overlapping pattern ensures that the chips generated are finely broken up, offering improved chip disposal properties.
- High Tool Rigidity:
- The body is made from special grade alloy steel that ensures rigidity under high temperature conditions. Design and manufacture of the body was carried out using the latest CAD technology. This resulted in a narrower flute geometry for effective chip control that prevents jamming and also maintained essential tool rigidity.
- Tool Geometries:
- Available in Ø50mm with combination lock or BT50 shanks with 3 different flute lengths of 105, 155 or 205mm.
- Insert Grades:
- The SPX series has inserts supplied in two versatile grades, both of which are Miracle coated, VP15TF and VP20RT. For cast iron machining VP15TF is the ideal grade, whereas VP20RT is ideal for pre-hardened and alloy tool steels.
- Insert Geometries:
- The SPX uses three insert geometries. Inserts located in the flute use all four corners, making them highly economical. Inserts used in the base and at the peripheral edge of the base have 2 cutting edges. The SPX is designed to ensure that there are 4 effective inserts working at the base of the flute, therefore making it possible to increase machining productivity.
