Equipment
CNC SIEMENS 840 D-SL Control panel on operator side, hinged, screen 15 TFT.Operating field label with symbols Multiple light for operating status display and fire extinguishing system Telediagnostic: Machine control via VPN router with customer’s network Safety integrated for NC axes, version with PROFISAFE Machine column quick retraction for protection of workpiece and tool in case of power failure Softwarepackage Corundum: Generating grinding / dressing (monoworm), profile grinding / dressing (roughing and finishing wheel), automatic centering, tooth correction, asyymetrical crowning conicity Installed hydraulic unit SKF consumption lubrication for guides and ballscrews Measuring systems with sealing air Coolant device for cooling and rinsing the tool and for flooding the bed Table with direct drive, max speed 3000 tpm NC-jet for following up the cooling jet to the decreasing diameters: Base support on bed of grinding head, linear carriage with AC-drive, travel 45 mm, flow sensor Coolant nozzle for NC nozzle, nozzle width 55 mm, for tool diameter 202-320 mm, module range 1-6 Recirculation system for coolant system Fully protected cabine Operating door, manually open and close Interior trim on the backrest, independent of the backstay arm or ring loader movable lifting plates Threading-positioning on the table for centering the tool in pre-toothed worpieces with evenly distributed over the wheel circumference tooth gaps, or for positioning of the tool to holes, grooves or nubs in the workpiece Dimensional control device, displaceable on the grinding head with a measuring position. The probe sequentially scans the position of various control surfaces. The machine control calculates correction values from the measured values. Hydraulic clamping device Interface clamping cylinder Column of high rigidity for axial travel of 660 mm NC counter-support, travel programmable, max. 300 mm, collision monitoring for the downward movement Counter-support interface with closing head system HSK-A 50 Handheld control unit for SIEMENS 840 D type HT 2 Additional control panel installed on the belt in the housing Coolant cleaning system for corundum, consumption-free, HOFFMANN HSF 200, with cooling unit. Flushing attachment for clamping devices in- and outside Flushing hand-gun Electrostatic air cleaner Threading sensor with amplifier, module range 1-1.5 Handling device with rotary arm on the couter support with electr. hoist for loading and unloading tools and fixtures Grinding head as NC swivel head (A1-axis) with digital drive CO2 fire extinguishing system Ring loader RL B1 with 2 stations. Lowering the workpiece in the work room with max. 100 mm stroke with digital drive. The change of workpiece is made by a 180 ° rotary movement with digital drive 2 parallel grippers for RL B1, max. 8 kg per gripper Quick change system for gripper inserts Electrical integration of external automation into the machine Clamping device with hydr. mandrel; 8mm Gripper inserts hardened for 2 parallel grippers with workpiece diameter 130 – 180 mm Additional software for dressing grinding worms in a two-flank process. The right and left flanks of the worm are profiled and sharpened at the same time. For multi-start worms, each gear is dressed separately. Special program warm-up cycle Machine was only 1 year in production, excellent condition! Option: Pallet conveyor system including pallets made by WEKAL Clamping of ginding tool in main bearing HSK-100 Grinding head GH 4.0 with watercooled, direct drive grinding spindle 35 KW, max. speed 10.000 rpm, tangential axis (V1-axis) with roller linear guide system, tangentioal travel 230 mm Electro-mechanical balancing system for balancing of corundum tools in the machine NC dressing unit with 1 NC axis for dressing grinding worms or form grinding wheels with an independent, frequency-controlled spindle, controlled by machine control Control cabinet with machine control SIEMENS 840 D (SL), control with integr. PLC in the control cabinet, in conjunction with SIEMENS drive technology |
