Planmaster - Flexible machining of large work pieces

The gantry concept allows maximum precision with large workpieces. For this purpose ELB has designed two model ranges, which have set new standards for flexibility and precision. The Planmaster series can be subdivided into two machine families as follows:

Planmaster machines with reciprocating machine table are suitable for grinding cubic workpieces up to a width of 2000 mm and a length of 4000 mm.
The Planmaster RT has a rotary table on which round-symmetrical parts with a diameter of up to 2000 mm can be machined. Using the rotary table as a B-axis allows machining of off-centre details with extreme precision. The rotary tables are equipped with hydrostatic bearings to guarantee maximum precision even under heavy loads.

Up to 4 vertical slides can be mounted on the cross-beam of the Planmaster. These can be fitted with horizontal, vertical and swivelling spindles. Combining a tool changer along with measuring probes for the vertical spindles transforms the Planmaster into a high precision grinding centre tailored to your requirements.     Advantages at a glance: + For components up to 2000 mm in width + Maximum precision due to gantry design + Rotary tables up to 2000 mm + Up to 4 vertical slides possible + Flexible process execution + 4 or 5 axis machining

Planmaster		10 (RT)	15 (RT)	20 (RT)
Grinding Width (table diameter)	mm	1000	1500	2000
Maximum Cross Travel	mm	1000/2000/3000/4000
Grinding Height	mm	850
Table Load	kg	4000	6000	8000
Spindle Drive	kW	15-50
Spindle Cone	mm	75, 90, HSK 63

The little brother of the Planmaster series is called the Planmaster HP. Workpieces up to a width of 1500 mm and a length of 3000 mm can be ground on machines of this type. The hydraulic table drive provides excellent results in surface finish and workpiece geometry even with large and heavy workpieces. Dressing can be accomplished by means of a wheel-head mounted straight-line dresser equipped with single point diamonds or with table mounted dressers.
The generously sized cooling system for the hydraulic oil and the grinding spindle motor allows the Planmaster HP to retain its excellent precision during all operating stages.  

When only surface grinding operations are required, the Planmaster HP is equipped with the ELB-Comfort control. If profiles are to be dressed and ground, the Siemens STC control is best suited and provides easy operation.     Advantages at a glance: + For components up to 1500 mm in width + Maximum precision due to gantry design + High thermal stability + Convenient control + Ease of operation

Planmaster HP		10	12	15
Grinding Width	mm	1000	1250	1500
Grinding Length	mm	2000	2500	3000
Grinding Height	mm	650
Table Load	kg	4000	6000	8000
Spindle Drive	kW	22
Spindle Cone	mm	75
Wheel Dimensions	mm	500x100x203.2

The Planmaster HP represents a cost effective alternative when large components are to be ground with a high degree of accuracy.
