Drake’s 4-axis CNCrack mill is designed and programmed for high speed manufacturing of power steering racks in a flexible cell environment.

Maximum Productivity Automated Production The 170x200 mm cutter mounts on a #50 taper arbor that is supported by heavy- duty front and outboard bearings. The 15 kW (20 HP) gear reduction spindle is rated at 80 m/min (260 SFM) allowing for aggressive metal removal rates with coated HSS or bridge material cutters. Ask about a carbide cutter option. Typical cycle time for 6°helix racks with 8 mm DOC is 35 seconds–floor- to-floor. Proven Performance Stability and Accuracy The machine features a fully adjustable automatic loader with entrance and exit magazines that hold 10 parts each for part lengths from 500 to 750 mm and diameters from 25 to 35 mm. The Drake GS:RM is proving itself over the world, and has earned a perfect “10” customer satisfaction score from one of the world’s largest auto parts makers. In addition to high production, themachine gives a near grinder-like finish of 35 Ra on steering racks. This totally integrated milling system is built for stable and accurate machining with a mineral filled cast polymer base, linear roller ways and a Fanuc CNC servo system. Automated or Manual Cell Operation Running Multiple Part Families? Drake will equip your mill with a CNC- controlled helix swivel (up to ±20°) and power table positioning with tenth-micron scale feedback for dialing in the center tooth position, helix, and over ball dimension. The GS:RM is a small compact machine that fits well in a flexible automated or manual cell environment. Machine width is only 2500 mm (98”) with a 1000 mm (40”) load height. Front access automatic loader/ unloader easily ties into your automated cell conveyor system. Shuttle raw parts into the loader from a bar machine or gun drill operation and finished parts into a washer and on to hardening. Fast Setups With PartSmart™ programming, your opera- tor changes jobs with menu-driven ease. No programming knowledge required. Setup time between parts is under 10-minutes– including cutter change. Drake provides a quick-change arbor and cutter change jib crane to minimize tooling change downtime.
