machine description

Diskus double surface lateral grinding machine with vertical spindles.
 
This machine type consists of a steel-welded box frame design, which has higher flexural strength than a comparable portal machine. It has two vertical, directly motor-driven spindles located on the same axis, with liquid cooling. Each of these spindles is driven by 23 kW to 48 kW. They are attached to compact slides with self-aligning bearings, which perform all infeed and return motions using precision screw drives.
The machine type required for your application can be used as a plunge cut as well as through-feed machine. The planetary gear drive provided allows a number of workpieces to be machined simultaneously with controlled rotation. The grinding tools infeed using the plunge cut method while positioned in a planetary gear rotating around its own axis. The same machine can be used for through-feed by replacing the transport plates.

machine description

Diskus lateral surface grinding machines with moving vertical spindle.
This machine type is a machine with vertical motor-driven grinding spindle. The workpieces are clamped and ground using clamping devices designed for the specific type of work. The devices are fastened to the machine bed. The column saddle on which the motor-driven spindle is mounted, is used as downfeed, dressing and oscillating carriage.
 
The unfinished and finished parts are transported by an automatic charging/discharging system, which can be installed parallel to the machine in various directions for the operating sequence. The workpieces are clamped with clamping devices designed for the specific type of work.
The machine has 2 clamping devices and one grinding tool. While the first workpiece is being ground at station "A", a second workpiece is simultaneously discharged and a new workpiece charged. In the next cycle, the workpiece at station "B" is ground, while the first workpiece is moved out and a new workpiece loaded again. During this cycle, the wet grinding area is locked to protect the operator.
 
Workpieces can be measured with extremely high precision during the program sequence with the built-in measuring system. The measuring results can be used for dimensional corrections on the machine if required.

attendant technologies

Continuous plunge cut grinding - Type DDS
In this grinding process the workpieces are guided through the grinding wheels with the aid of a transport plate. The plunge cut is accomplished separately for each workpiece.

Continuous plunge cut grinding - Type DDS
In this grinding process the workpieces are guided through the grinding wheels a number of times with the aid of a transport plate. A plunge cut is accomplished during each pass until the final dimension is reached.

Continuous plunge cut grinding - Type DDW
In this grinding process the workpieces are guided through the grinding wheels with the aid of a transport plate. The plunge cut is accomplished separately for each workpiece.

Continuous plunge cut grinding - Type DSR2
In this grinding process the workpieces are guided beneath the grinding wheels with the aid of a transport plate. The plunge cut is accomplished separately for each pair of workpieces. The special feature is that workpieces with different heights (increments) can be ground.

Plunge cut grinding (with oscillation) – Type DHS
In this grinding process the workpieces are guided beneath the movable grinding wheel with the aid of a charging unit. The plunge cut is accomplished with oscillation while the workpiece is beneath the grinding wheel.

Plunge cut grinding (with oscillation) – Type DS bottom
In this grinding process the workpieces are guided to the grinding wheel with the aid of a guide. The plunge cut is accomplished separately on each workpiece while the grinding wheel oscillates.

Plunge cut grinding (with oscillation) – Type DS top
In this grinding process the workpieces are guided beneath the grinding wheel with the aid of a guide. The plunge cut is accomplished separately on each workpiece while the grinding wheel oscillates.

Plunge cut grinding (with oscillation) – Type DW
In this grinding process the workpieces are guided against the grinding wheel with the aid of a guide. The plunge cut is accomplished separately on each workpiece while the grinding wheel oscillates.

Plunge cut grinding with carriage (with oscillation) – Type DDW
In this grinding process the workpieces are guided between the grinding wheels with the aid of a carriage. The plunge cut is accomplished with oscillation while the workpiece is between the grinding wheels.

Plunge cut grinding with rocker arm (with oscillation) – Type DDW
In this grinding process the workpieces are guided between the grinding wheels with the aid of a rocker arm. The plunge cut is accomplished with oscillation while the workpiece is between the grinding wheels.
