Steering Sector Gear Shaping Machines

Yichang Changjiang Machine Technology offers Steering Sector Gear Shaping Machines, YK5612. It is a steady, reliable and highly productive machine tool for cutting, with either constant or variable ratio, the teeth of steering sectors used in automobiles ranging in carrying capacity from tiny to heavy type. It is suitable for the mass batch production in professional industry, servo, CNC system, and three axes that are timed to one another govern the machine. The primary motion is driven by an AC servomotor and controlled by a frequency conversion, and the speed can be changed steplessly. As the cutter adopts V-type rolling guide, backlash is avoided. The clamping of work piece is performed by a hydraulic cylinder without the support of oil plate. As an outstanding property, five cutting cycles can be provided during a single cutting process; and the strokes will be changed automatically according to what have been preset when a new cycle begins. Throughout the cutting process, the speed of cutting can be changed; chip is conveyed automatically by a magnetic chip conveyor. PC bus is introduced into the CNC system, which is expandable; the host computer is supported by a 32-bit CPU: The abundant system software make the following items possible: Cutter parameters input under the guidance of menu of options and Chinese character prompting lines; Emulation of the figure of cutting process; On-line display of the work piece-cutter generating process; On-line display of diagrams necessary. Specifications: maximum diameter is 120mm; maximum module is 10/12mm; maximum face width is 80mm; angle of teeth to shaft axis is 0-7.5 degree; diameter of worktable face is 300mm; diameter of main spindle bore of worktable is 95mm; diameter of taper hole of work spindle is 140mm; maximum transversal stroke of worktable is 220mm; maximum column move distance is 100mm; number of strokes of cutter spindle is 90-660 stroke/min; cutter relieving amount is 0.45mm; distance from bearing surface of cutter to worktable surface is 130-248mm; rotary feed (C axis) is 0.04-0.5mm/stroke; work rotating speed (C axis) is 0.04-6r/min; radial feeding speed (X axis) is 1-2000mm/min; transversal feeding speed (Y axis) is 5-3000mm/min; total power is 13kw; net weight is 8000kg.
