Used GRAY RM-48 #9019839 for sale

GRAY RM-48 is a precision machine tool, designed for grinding operations of various gears and profiles. It features a powerful, highly reliable direct-drive spindle, which is capable of reaching speeds up to 1500 RPM with class-leading rates of acceleration and deceleration. This robust architecture also ensures smooth and precise operation during high-speed grinding operations. The machine's headstock contains a permanently grease-packed precision-machined ultimate-speed bearing, which eliminates any need for regular maintenance and ensures fast traverses and precise movements. This ensures that grinding operations have the smallest of tolerances and that all parts produced will have extremely low runout figures. The spindle and its associated components are powered by an AC motor, which provides the user with a reliable, stable and efficient source of power. This motor is outfitted with adjustable GRAY Drive semiconductor components, meaning that the spindle will never overheat or lose power during operation and will always remain within the desired operating parameters. This also reduces equipment maintenance requirements, since the system is capable of monitoring and adjusting its output automatically. The grinding wheel is located on the left side of the machine and is able to pivot up to a maximum angle of 30 degrees. This is achieved using a unique motorized hydraulic indexing unit, which enables extremely tight tolerances of grinding angles. The grinding wheel is also tilted with up to 3 degrees of travel, allowing for the grinding of different disc shapes and profiles. The machine is equipped with a CRT-equipped PC-based control machine, integrated with the latest PLC chip technology. This enables the use of the optional vector programmable GRAY software package, which is capable of performing sophisticated grinding operations without the need for manual processing. The machine can be custom-programmed for a variety of grinding operations and has a program memory capacity of 200 of such operations. RM-48 machine is a durable, reliable and efficient tool for grinding a wide variety of gears, profiles and discs. Its powerful spindle, precise headstock bearing and its PC-based control tool all work in unison to ensure smooth and accurate operation. Its ability to tilt the grinding wheel, as well as its powerful vector-programmable software package, ensure that all of your grinding operations will be made with the utmost accuracy and precision.
