20kmc / 20kmcu

Overview

Model 20kmc / 20kmcu. Available spindle heads listed are 45º automatic head and Direct Outlet head; the 45º automatic head is specified as 360.000 positions. Drives for the X, Y, Z axes are X: R / 6, Y: B / 80, Z: B / 80. Positioning and repeatability accuracy - mm: 0,008/4.000 and 0,005/4.000. Key dimensions and travels include Table length - mm: 5.700-11.700, Table width - mm: 1.200, Longitudinal travel - mm: 4.200-10.200, Cross travel - mm: 1.250 (1.500)*, Vertical travel - mm: 1.000 (1.500)*, and Min – max distance from table to spindle nose - mm: 0-934 (1.434)*. Feed, spindle and tooling data: Working Feed - mm/min: 6 - 10.000, Rapid feed - mm/min: 25.000, Speed of the spindle head - rpm: 35-3.000 (4.500-6.000)*, Power - kW: 28, Tool magazine: 30 (40-60-80)*. Allowed weight on the table - kg: 3.500 / m2; Approx. net weight - kg: 30.000-62.000. Operator's platform: -. Intended for industrial-scale machining of large and heavy components such as structural parts, large molds/dies, energy and power-generation components, shipbuilding sections and heavy machinery frames, where long table lengths and high table load capacity are required. The long longitudinal travel (up to 10.200 mm) and table lengths to 11.700 mm support machining of long billets and assemblies in a single setup. Configuration variants (cross/vertical travel options, higher spindle-speed bands and expanded tool magazine sizes) enable tailoring to either heavy roughing (lower-speed, high-power cutting) or higher-speed finishing operations. The X axis rack drive combined with Y/Z ball screws provides a balance of long-travel capability and positional accuracy; this makes the machine suitable for production and manufacturing R&D environments that require repeatable large-format milling with multi-tool automatic sequencing.
