Toolroom Lathe Offers High Precision
Grizzly Industrial’s G0740 provides a distance of 40" between centers and a swing over the bed measuring 14.17".
Grizzly Industrial’s G0740 lathe provides a distance of 40" between centers and a swing over the bed measuring 14.17". The high-precision toolroom lathe features a D1-5 spindle powered by a 5-hp, 220-V three-phase motor. A completely enclosed gearbox provides quieter operation while extending gear and bearing life. A 16-speed headstock features precision-hardened and ground gears in an oil-lubricated bath. The machine features hardened and ground V-way bed with Meehanite castings, and a coolant system that includes a pull-out chip tray and full-length splash guard. The lathe is equipped with a quick-change toolpost, steady and follow rests, an 8" three-jaw scroll chuck, a 10" four-jaw independent chuck, 10" faceplate, two dead centers, a halogen work light and a foot brake.
Finding a way to fixture contoured marine propellors proved to be this shop’s biggest challenge in developing an effective automated machining cell.
The additional rotary milling axis on these machines allows them to complete many types of complex parts in a single setup, but these machines have gained a reputation for being difficult to program. Today’s CAM software, however, eases the programming challenge significantly.
As demonstrated at this Cincinnati-area shop, machines that both mill and turn shine brightest when workpieces are massive.
