G 160 generating gear grinding machine
New G 160 generating gear grinding machine
Access to the machine Machine highlights
On the G 160, particular attention has been paid to ergonomics. All needs of the machine engineers for operating, setting and servicing the machine were carefully respected.
+ Chip-to-chip time less than 2 sec.
Changing tools is simplified by moving the main columns Y-axis and the tool spindle very near to the operator’s door. In this way, the wheel flange comes right in front of the operator and the reach into the machine to access the grinding wheel is very short. The same applies to the dresser, which is located next to the operator’s door.
+ Innovative and patent-pending machine architecture + New virtual Y-axis configuration for high dynamic stiffness
A secondary loading door provides access to the two work-spindles when retracted into a loading position. This is where clamping fixtures, including tailstock centers, are changed and meshing sensors get adjusted.
+ High thermal and mechanical stability
The challenge In the automotive industry the manufacturing of high-precision gears and transmission components is an element of crucial importance. In recent years an increasing demand for the performance requirements of automotive drivetrains has put a considerable pressure on gear manufacturers. The automotive industry is constantly searching for new production solutions that ensure the greatest efficiency, low maintenance, reliability and the fastest possible production times in gear manufacturing. A typical feature of current gear grinding machines are the 2 workpiece spindles for shortening the non-productive time when changing parts. Despite this, the non-productive time has never gone under 5 seconds because the spindles are located on
a rotary table which is hydraulically locked in position but is inaccurately floating while moving. The unlocking, the settling after moving and the locking in the new position take more time than the motion itself and cannot be any faster by design.
Our solution The new G 160 splits the X-axis of current machines into two linear slides (X1, X2), each of which carries one workpiece-spindle. So both work-spindles are under full position control anytime. Being driven by high dynamic 30 m/s linear motors changing spindles comes down to 2 seconds including simultaneous repositioning of the tools with the Y-Z-A axes.
Your advantage The new machine architecture is a breakthrough and ensures the best production times on the market. The increasing demand on efficiency and noise emission of the gears pushes the grinding process to its limits. The stiffness and stability of a grinding machine is the main design target for such a high dynamic process, and the G 160 presents a unique design to optimize the dynamic stiffness compared to current standard machine architectures, in particular the new virtual Y-axis configuration.
Each linear slide carries a workpiece spindle
The loading and unloading interface is designed to attach a variety of external loading system, ranging from simple pick-and-place to flexible robot systems. To avoid sacrificing cycle time, EMAG SU can offer different solutions based on real floor-to-floor time. All mechanical, fluid and electrical components are easily accessible for service or maintenance either from outside the machine or just by opening a door to the service isle between machine and electrical box. All built-in motors and encoders have separate covers to provide access if needed. All these features fit into an attractive, incredibly small total floor space.
