Racer Machinery International is displaying its Standard Modern CNC S-22 slant-bed lath, developed using hand-scraped surfaces, a built-in slant that offers more rigidity, thermal stability and precision. In addition, three-point roller bearings, a dynamically balanced spindle, as well as ground precision ballscrews are standard. The S-22 is the most aesthetically pleasing addition to any shop floor.
The S-22 features a hydraulics system as well as automatic lubrication, coolant, chip conveyor and multiple windows to oversee parts in process. Operational ranges include a 22" swing over bed; a turning diameter of 22", 24" or 46"; a Z axis; and a 10-station VDI turret. The headstock has a A2-6 spindle nose, a 3.06" spindle bore and a 20-hp spindle drive that provides speed from 40 to 3,500 rpm. A gearbox is available as an option.
A significant feature is the machine’s Shop Turn programming software, which is designed to provide an intuitive conversational programming system. The user-friendly CNC makes this the ideal machine for manufacturers and training facilities, since its Siemens software package minimizes the effort required programming by using interactive graphics and simulations, according to the company.
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.
This manufacturer’s use of live-tool lathes overcomes labor cost in various ways. One of the latest sources of savings involves bringing another operation—hobbing—into these machines. INCLUDES VIDEO.
