Compact solution for creep-feed grinding
The microCut model was specifically designed to meet the requirements of profile and creep-feed grinding applications. The modular traveling column design offers a small foot print which can be easily configured into economical production cells frequently used in the turbine industry. This machine is available in compact standard sizes but special designs with spindle power up to 52 kW are also feasible.
The integration into production lines is achieved through automatic material handling and tool changes. A common solution to reduce non-productive time is to equip the microCut with an index table to allow loading and unloading during machining times.
For high-precision applications, dressing of the grinding wheel can be done on the table with a roll dressing unit or via interpolation of feed and cross axes. For high-production grinding, head mounted roll dressing units for intermittent or continuous use are available. For complex grinding tasks, dual head mounted dressing units and tool changers are being used. The microCut is frequently used with Corundum, CBN and diamond grinding wheels.
A trunnion table can be mounted on the machine table to allow the processing of multiple sides of a work piece. With the Sinumerik 840D sl CNC control the microCut can grind complex shapes by interpolating multiple axes. Proven ELB programming templates are available for most grinding applications. We have application engineers and programmers on staff for every grinding task.

microCut 320 DS/TS
-
Economical creep-feed grinding
The microCut 320 DS / TS is equipped with two opposing grinding spindles. This design was specifically conceived for the simultaneous grinding of opposing surfaces. This grinding process offers numerous advantages including a reduction in processing time, increased parallelism and profile symmetry of the work piece. Additionally, the opposing grinding forces counteract and avoid material stresses in the work piece.
Profile dressing of the grinding wheel can be performed on the table or with headmounted roll dressing units. Headmounted dressing units can be used intermittently or continuously. To accommodate for the offset between two profiles the position of the upper dressing unit can be adjusted in the cross direction via CNC controls. This machine is commonly used to grind the fir tree profile on turbine vanes. To increase productivity this model can be equipped with a loading table rotating +/- 180º. This table allows the loading and unloading of work pieces during the grinding process. Grinding wheels and dressing rolls are being changed in a separate machine area to improve ease of operation.
This machine comes equipped with the Sinumerik 840D CNC control system by Siemens and is prepared for a multitude of applications by ELB pre-defined program cycles. We have application engineers and programmers on staff for every grinding task.
