When cross machining is required, three cross spindles (standard on type VIII model) can be mounted, totaling eighteen tools: five turning, seven rotary, and six drilling tools. The three cross spindles can also be used as end-face drilling spindles by rotating the holder 90 degrees. When end-face machining is required on the front and back, an optional six live tool holder is available. With this tool holder option the L20 now totals 21 tools: five turning, ten rotary, and six drilling tools. The L20 type VII offers five turning and five live rotary tools (cross milling/drilling) on the gang plate. When only turning is required, the L20 type V offers five turning tools on the gang plate with no live tools. As future live tool needs may be required, the type V model can be upgraded to a type VII or VIII by purchasing additional live tool holders that easily fit into the existing L20 gang tool plate. This modular concept can support a wide variety of machining processes depending on your current or future parts machining requirements.
