Linear drives boost MAP LPZ 630 5-axis machining centre’s feedrates
Linear drives on the latest MAP LPZ 630 5-axis machining centre give 120 m/min feedrates with an acceleration of 20 m/sec² throughout its 700 by 985 by 500 mm XYZ working envelope.
The MAP LPZ 630 is the mid-range version of the MAP LPZ series of 5-axis machines. It has high speed spindle options of 40,000 rpm through HSK E40 spindle or 20,000 and 18,000 rpm. A heavier duty HSK A63 taper spindle with up to 28 kW of power with 83 Nm of torque is also available, says MAP UK agent 2D CNC Machinery.
The spindle assembly on the heavy duty cast iron bed MAP LPZ 630 is carried on a low-mass aluminium X and Y gantry slide and is positioned through fully enclosed linear drive units mounted outside of the working zone. High levels of thermal stability, in conjunction with absolute positioning scales, enable a positioning tolerance within 0.003 mm. Repeatability is 0.005 mm within the three linear axes and ±5 secs in the trunnion mounted, direct driven A-axis and rotary B-axis. As an option, the 360º B-axis is also able to rotate at up to 80 rpm or as a further option at up to 200 rpm for integrated turning cycles.
MAP evolved within the Fritz Werner group's cell and system engineering operation to create the modular constructed niche product line up. Thus the MAP machining centres are easily customer configurable from stand-alone installations through to cell and system-engineered solutions.
Automation packages available include three and six pallet change systems, integrated gantry workpiece loaders for smaller components and highly flexible robot-based systems. Tool magazines holding 24, 36 or 78 tools up 125 mm diameter by 330 mm in length are available.
The MAP LPZ 630 is controlled by Siemens 840D CNC unit. Map's software development operation is able to tailor specific production and process management solutions, integrate transportation, work scheduling, tooling, full system management and maintenance.
