Actual technical data after Retro-fitting (TBD): originally offered in 2006
1.) Siemens SPS (PLC) – Simatic S7-300
2.) SM-Motion CNC-control – SM 400
3.) 3 servo motor drives
4.) Ball screw spindle for driving the grinding head
5.) Separate control board
6.) Easily operative control panel
7.) Memory: 200 tools
8.) Easy put-in of hob data
9.) Grinding wheel swivel (y-axis): Automatic identification
of hob lead if unknown.
10.) For determination run-out the work piece is turned 360°
by push bottom
11.) Flutes / gashes: 1 – 99 / straight flutes or spiral
12.) The spiral is calculated by adjusting the grinding head
and is set manually by push bottom
13.) Lead of flutes: 120 up to 19000 on demand easy finding
of hob lead via machine control unit
14.) Grinding slide (x-axis): Working speed adjustable in steps
1,6 m/s to 16 m/s
15.) During roughing and finishing different working speeds
of grinding slide possible
16.) Working speed of grinding slide can be changed during
grinding operation
17.) During roughing and finishing different working speeds
of grinding wheel possible
18.) Grinding wheel speed: digital display
Infinitely variable revolution permits highest performance as
regards time and quality when grinding the different material
and coatings. Controlled oil grinding motor drive permits
continuously equal grinding wheel speed.
19.) The five counter determining the number of terms can be
set during the program is in force
20.) Simple setting of machine (no change gears, no indexing
plates required anymore / time saving)
21.) Grinding of hobs can also be done manually.
