RTG3800

CNC Tool Grinding Machine

The RTG-series is the world’s highest-level grinding machine in the 21st century. It was developed from our long years of expertise and technological know-how from dealing in PCD grinding machines by KANEHIRA. They are a leading grinding machine manufacturer with over 30 years experience in the manufacture of PCD tool grinding machines.

デジタルだから出来ること

By using digital camera, a initial preparatory work performs smoothly, and various measurement and saving measurement image in real time.

Saving a work before and after the processing, so that it contributes quarity assurance.

Observing from low to high magnification by a zoom lens. Especially small diameter nose R set smoothly in high magnification.

Crack or separation of work can be observed by epi-illumination. Especially it demonstrates on regrinding process.

Features

Machine mounted laser measurement (optional)

The Blum laser system measures the configuration of the workpiece on the machine,completely automatically. The results of the measurements are used to prepare for the next machining session,to reduce the time needed for highly accurate machining. Setup time is also substantially reduced.

AE sensor system (option)

The AE ultrasonic sensor incorporated in the main spindle alerts the operator to any micro-vibration which might occur in the main spindle during operation. The alert is shown in real time on the monitor. It can also be used for checking the resistance while grinding,for sensing contact,and other purposes.

Machine mounted dresser

The high-performance dresser mounted on the machine continuously keeps the diamond wheel aligned and flat,for the best accuracy. This provides high accuracy,great uniformity ,and high efficiency to your machining operations. Programming for constant compensation will get the most out of the NC.

High-rigidity bed

A number of thick ribs are used for the machine,after careful consideraton of the distribution of mass on the superstructure. This provides the rigidity required of a PCD tool grinding machine,as well as the ability to absorb vibration.

Space saving

The entire machine is enclosed snuggly in a housing that uses only a very small floor space for installation (1550mm x 1742mm).There are no unnecessary projections of doors or servomotors. The operation panel is carefully designed and organized for easy operation.

User macro

A great many user macro programs(some macros are optional) are possible, for easy and efficient operation. The machine comes with some macros already installed. Even operators who are not familiar with NC machines can easili progam a macro. We also stand ready to make customized macros, according to a costomer’s machining needs.
