SIP SPC 7140 SIP HORIZONTAL MACHINING CENTER

Technical Description

The SIP SPC 7140 is a horizontal machining center featuring a robust table/work support with a standard table size of 31.5" x 31.5" and an optional extended size of 39.4" x 39.4", supporting a maximum workpiece weight of 4,400 lbs. It utilizes a horizontal spindle with an HSK-A 100 taper, optimized for high precision and rigidity in high-speed machining applications. The spindle offers a top speed of 6,000 RPM, with an optional upgrade to 15,000 RPM, and power ratings of 68 HP (30-minute rating) with an option up to 93 HP, allowing for heavy-duty cutting and extended performance. The tooling system includes an automatic tool changer (ATC) configured as either a chain or tower, capable of handling 60 tools in standard setup, expandable up to 240 tools for enhanced flexibility. This machining center operates on 4 axes (X, Y, Z, and B), with the X-axis travel of 57.1 inches, Y-axis 43.3 inches, Z-axis 51.2 inches, and full 360° rotation on the B-axis. Each linear axis supports a maximum feed and rapid traverse rate of 1,572 inches per minute (ipm), ensuring fast and precise positioning. The combination of a horizontal spindle design with HSK-A 100 taper tool holding provides excellent clamping stability and dual contact at the flange and taper, critical for maintaining tool retention and accuracy at high spindle speeds. This configuration is ideal for demanding applications requiring large work envelopes, high rigidity, and high-speed machining capabilities.
