Star Micronics has developed the SD-26, a new model Swiss type automatic lathe(*1) capable of up to 26-dia. machining. It is mainly targeted at complex-shaped parts for automotive, hydraulic/pneumatic equipment and medical-related uses, and will be available for sale worldwide from April 2023.
The SD-26 employs a gate-shaped tool post with a cross-guide structure that distributes the load evenly, arranged on the gang-type tool post for front-end machining so as to surround the guide bush that is the machining point for various tools such as turning tools and drills. The following 4 types are available, allowing you to select the most suitable tool post specification according to the application of the workpieces.
1) “Type S”: Equipped with a 4-spindle facing-type milling unit with a tool swivel control axis (B-axis) capable of programmable simultaneous 5-axes control. The upper section has one cartridge-type position with a 2nd B-axis mechanism that can provide swivel control for the dedicated tool unit. Various types of tool units can be mounted, including the world-first twin-thread whirling unit.
2)“Type G”: Equipped with a 4-spindle facing-type milling unit with a tool swivel control axis (B-axis) capable of programmable simultaneous 5-axes control. The upper section has two cartridge-type positions capable of mounting various tool units of existing models.
*The two cartridge-type positions are common to types G/E/C.
3)“Type E”: Equipped with a 4-spindle facing-type milling unit with a tool swivel control axis (B-axis) capable of programmable simultaneous 4-axes control.
4)“Type C”: Equipped with 4-spindle facing-type milling unit for which the angle is manually adjustable.
In addition, this type employs a guide bush/non-guide bush switching mechanism to flexibly support the increasingly diverse parts machining needs. This allows you to freely switch between the guide bush specification, which acts to prevent deflection of materials, enabling high accuracy machining of long and narrow parts such as motor shafts, and the non-guide bush specification, which enables machining of short parts such as nuts without wastage, reducing the amount of waste material to be disposed of, on a single machine.
NOTE 1: Swiss-type automatic lathe
Known as a “sliding head-type automatic lathe” as well, it has remarkable characteristics of high-precision cutting of components with longer length compared with the diameter.
