Milling Electrospindles

High Frequency Electrospindles for  milling can be supplied: cylindrical , with or without fastening flange , or with square section to work on 5 axes machine tool. The maximum speed is 75.000 rpm ( with HSK E 25 ) and the power can be supplied to 60 KW S1 with 300 Nm of torque.

 

Spindles of this serie are all  geared  up to receive cones  ISO DIN 69871, BT, HSK DIN 68983 - CAPTO NIKKEN - 3 LOCK and others

The tool change is incorporated and takes place automatically through hydraulic or pneumatic pressure while sensors  are controlling  shifts to ensure safety and reliability throughout the  years.

Most of them have ceramic hybrid bearings , permanently lubricated with grease or oil-air and are minimal pre-loaded in a variable manner to ensure rigidity , precision and durability. Following up your requirements, they can be equipped with various options such as:

 

Bearing temperature’s Sensors

Control vibrator’s Sensors

Rotary joint with liquid flow through the centre.

Encoder for closed loop vector control of the electrospindle . This accessory allows you to perform the correct positioning of the shaft before starting the tool change. It also allows you to achieve high torque at low engine speeds and it is essential to be able to perform delicate work such as rigid tapping .

 

Instant Solutions’ spindles can be interfaced with major manufacturers of CNC and spindle drives :

 ( FANUC - SIEMENS - HEIDENAIN - INDRAMAT - NUM -etc . ) 

 

These Series are equipped with :

 

  • Double temperature’s sensors for motor HF
  • Sensors for monitoring tool change
  • Pressurization spindle’s nose
  • External anti-corrosion treatment
  • Cooling recirculating liquid

 

 

 

We realize also customized spindles for single manufacturer of Machining Centres and high-speed Machines

  

 The table, here below, shows only the data that can be achieved for each size of spindle .
