High Frequency Spindle Units for Milling

Type Series RHF

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 1,6 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 on request. Spindle Head acc. to HSK 69063: HSK 32, 40, 50, 63, 80 for the Spindle Noses.

Type A

Type C

Type E

Self releasing taper 7/24 per DIN 2079
SK (25), 30...SK 50

Sleeve Ø: D = 120...280 mm - others per agreem.

Tool Retention system with spring actuation, release by hydraulic pressure. Blow-out air for tool adapter, or through-spindle coolant options.

Power: (S1) 8 kW... (S6) 50 kW
Torque (M) 4 Nm ...130 Nm
Speed (n) depends of Spindle size/Bearings
