machine description

<b/>

Diskus double surface grinding machine with horizontal spindles. This machine type is a steel-box frame welded construction with two opposing horizontal grinding spindles with the same axis. These are directly driven, liquid cooled motor driven spindles whose main spindle drives each have a motor output of 24 kW to 100 kW. Various types of workpiece transport are possible. Linear workpiece feed can also be selected, depending on the workpiece geometry. In this case, the workpieces are fed and guided with the help of guide rails for the grinding tools. At the discharge, Diskus's own ionic 100 % measuring control measures each part. The measuring results from this post-process measuring control are transferred to the SIEMENS 840D machine control and used for automatic correction as required.

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 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.

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.
