1 LFG-3540 CNC Gear Form Grinding Machine

2 Machine Introduction Presentation of High Precision and the Best Performance-To-Price Ratio LFG-3540 CNC Gear Form Grinding Machine Luren Precision Co., Ltd. has been dedicating to the R&D of gear machining since We have extended the cut-tools technologies of Mechanical and Research Laboratories, ITRI, and integrated the research resource from the best universities, built the production lines of hobs and shaving cutters, and successfully and stably sold our products to European, American and Asian markets. In grinding machines, Luren Precision produces the gear form grinding machines, worm thread grinding machines and cutting tools sharpening machines; and earns outstanding reputations in the fields. The LFG-3540 Gear Form Grinding Machine applies the FANUC controller and high-speed grinding spindle; through the Luren Precision-developed intelligent conversations window software, it can flexibly output the required tooth profile and grinding parameters. The workable machining workpieces include the involute gears and cycloidal gears; the high-efficiency and high precision expressed from the products are equivalent to worldwide-top brand's ones; LFG-3540 is your best choice. 1

LFG-3540 applies the globally famous FANUC controller and servo & directdrive motors; each axis can move simultaneously and receive a highprecision performance. The Luren Precision-developed intelligent conversations window software supports the complete machining process. Machine can generate NC program automatically through the parameters-input and setting of grinding conditions via the conversation, and thus increases the working efficiency significantly. 2

4 Unit Introduction Unique Design Brilliant Performance Except the standard mechanical functions LFG-3540 could also option the Luren-developed special mechanical functions, which including rotary dresser unit, automatic electric adjustment of the tailstock, automatic positioning and on-line grinding wheel balance system. Built-in grinding spindle 220G(Outside diameter 220mm) Equipped with lager high-precision performed bearings. The stronger cutting force could improve the processing efficiency. 170G(Outside diameter 170mm) HSK grinding wheel arbor for quick change-over, suitable for smaller quantity and versatile gear grinding. A smaller grinding wheel is mounted to grind smaller gears, or gears with a close shoulder. HSK arbor Dressing unit Diamond point dressing unit (standard equipment) Disk dressing unit (optional) Rotary dresser has long lifetime, high stability and makes little tooth-profile deviation. Tailstock adjustment unit Manual adjustment (standard equipment) Electric adjustment (optional) Special mechanism Automatic positioning (optional)) Enable to detect the excessive run-out of the blank before grinding and reduces the installation time of the operator. On-line grinding wheel balance system (optional) Easy to correct the run-out of the wheel. 3

5 Software Technology Innovative R&D Intelligent NC Technology Intelligent Software Technology Luren Precision has developed the gear form grinding software, all inputs apply the dialog blocks that enable operator to set gear data and grinding process parameters in a flexible matter; the software will generate complete NC program automatically and guide operator to run the grinding process. Involute gear Optional to provide anti-twist for gear tooth flank (Bias-free) function. Cycloidal gear Gear data Follow workpiece drawing to input the gear parameters and automatically calculate the matched gear profile. Freely zoom-in/out the graphics to check/confirm gear-profile details. Gear data According to workpiece drawing to input the gear parameters and automatically calculate the matched cycloidal gear profile and simulate assemble of the pin and cycloidal gear. Profile modification The drag-control-point curve facilitates operator to modify gear profile and lead crowning according to customer's requirement 4

6 Machining Machining Examples Gears are widely used in daily life. The main purpose of the gears is for the power transmission via different gear pairs to match of some change from the torque, speed and direction. The Involute gear characteristics compared to the other type gear profiles are easier to be machined, high replaced, heavy loading and easier to be assembled. The Cycloidal gear is used in high-precision cycloidal reducer which is also common in the robotic arm. Master gear The master gears can be used to check and correct gear measuring machine, also can be used in gear meshing test to check the workpiece to comply with the accuracy requirement. Cluster gear In order to increase the gear strength and reduce assembly error, gears are often designed on the gear shaft. Copper electrode The EDM can machine special material workpieces. The copper is the normal electrode material in EDM. Cyclodial gear Cycloidal reducers are capable of higher gear ratio, smaller volume and lower noise. 5
