High Frequency Spindle Units
for Grinding

Type Series GHF

Grinding Mandrel bore size: Ø 8...36 with connecting thread

with High Speed Spindle Bearings
with ceramic balls (Hybrid Bearings)

State-of-the-art Precision,

Radial tolerance <= 2 µm
Face runout <= 1 µm

Balance Class (Standard) G 1,0 acc. DIN ISO 1940. Sealing (standard) slinger disk with integrated Labyrinth Seal; (optional) Air Purge. Lubrication (Standard) Lifetime, using special grease (Optional) Oil - air mist lubrication per agreement. Increased rigidity, primarily from the higher number of balls inside the High Speed Spindle Bearings Particulars about Spindle Types on request.

Sleeve Ø: D = 80...170 mm - others per agreem.

Through shaft coolant (rotary joint)
Power: (S1) 1,5 kW... (S6) 35 kW
Torque (M) 0,15 Nm ...28 Nm
Speed (n) depends of Spindle size/Bearings

Example: GHF-Spindle D = 80 mm: n_max 60.000 min^-1 (Kopie)

Type Series GHC
