MARATHON SLT-500/1500 HORIZONTAL MACHINING CENTER

Technical Description

The MARATHON SLT-500/1500 is a dual-spindle horizontal machining center designed for heavy-duty turning and milling operations. It features a main spindle capable of handling workpieces up to 21.400" in diameter with a maximum turning length of 57.400", supported by a 16.000" chuck and 24.000" swing capacity. The main spindle operates at 2,000 RPM with 60 HP output, complemented by a sub-spindle rated at 2,000 RPM and 35 HP for simultaneous secondary operations on 16.900" diameter workpieces. The machine accommodates a maximum bar diameter of 6.000" and includes a rotary tool spindle spinning at 4,000 RPM with 7.50 HP for additional machining capabilities. The turret-based tool system provides 12 turning tools and 6 rotary tools, enabling single-point simultaneous cutting operations. With a 2-axis configuration, the machine delivers X and Y axis travels of 13.500" at 400 ipm feed rates and 590 ipm rapid traverse speeds. The Z-axis provides 43.300" of travel, also at 400 ipm maximum feed rate and 590 ipm rapid traverse. This configuration optimizes production efficiency for complex turning and milling requirements, making it suitable for precision component manufacturing in automotive and industrial applications.
