SMEC CO., LTD SL 5500M HORIZONTAL MACHINING CENTER

Technical Description

The SMEC SL 5500M is a high-performance horizontal turning center engineered for precision heavy-duty machining operations. This advanced CNC lathe features a 21-inch chuck diameter with a maximum swing of 35 inches over the bed, accommodating workpieces up to 6.52 inches in bar diameter. The machine is equipped with a single main spindle operating at 1,500 RPM with 40 HP continuous power, expandable to 1,200 RPM at 60 HP under optional configurations for enhanced torque applications. The dual spindle architecture—comprising both turning and secondary spindle capabilities—enables integrated simultaneous operations for increased productivity. The primary BMT 75 tool turret provides 12 tool positions for turning operations, with an optional BMT 85 turret offering additional machining versatility and 12 rotary tool positions. The machine accommodates two simultaneous cutting tools, expanding operational flexibility. With two independent axes controlling Z and X movements, operators achieve precise dimensional control and superior surface finishes. The rigid one-piece Meehanite casting with heavily ribbed torque tube design provides exceptional structural stability and vibration dampening, essential for maintaining accuracy during heavy-duty cutting. Featuring a non-stop turret indexing system with ±0.01 repeatability and 0.25-second index time, the SL 5500M delivers rapid cycle times and repeatable precision. The 10.4-inch color TFT LCD control monitor with 90-degree swivel capability ensures ergonomic operator access, while the Fanuc control system provides reliable, intuitive operation for complex machining sequences.
