Spindles at Roeders

Hauptspindel

For a high effi­cien­cy of the machine in the user-spe­cif­ic appli­ca­tion the spin­dle choice is essen­tial. There­fore, Roed­ers offers an excep­tion­al wide range of main spindles.

By means of a stan­dard­ised inter­face, which has been opti­mised over many years, espe­cial­ly ther­mal­ly, the main spin­dle is mount­ed in the Z‑axis of the machine. This allows for a cost-effec­tive change to anoth­er spin­dle type at a lat­er time, in case the appli­ca­tion for the machine changes. Options like vec­tor con­trol, shaft cool­ing, rotary lead throughs etc. are avail­able as need­ed. Roed­ers always has spare spin­dles in stock for all spin­dle types.

If an appli­ca­tion requires very high rpm and, at the same time, a rel­a­tive­ly pow­er­ful spin­dle, it is pos­si­ble to equip the machine with two main spindles.

A typ­i­cal com­bi­na­tion of two main spin­dles is:

  • Spin­dle 1: ball bear­ings, HSK E50 with 36.000 max. rpm
  • Spin­dle 2: air bear­ings (high­ly pre­cise), HSK E25 with 80.000 max. rpm

Auto­mat­ic tool change, laser mea­sure­ment, dif­fer­ent cool­ing lubri­cants, 3D probes and, in the case of jig grind­ing machines, all the nec­es­sary func­tions such as dress­ing, sound detec­tion-based mea­sure­ments, etc. are avail­able for both spin­dles.
Both spin­dles are inte­grat­ed into the machine as close to each oth­er as pos­si­ble, whilst being tem­per­a­ture-con­trolled with high pre­ci­sion using mul­ti­ple cool­ing cir­cuits. This ensures that the dis­tance between and the posi­tion of the spin­dles are kept absolute­ly con­stant, so that the high­est pos­si­ble zero-point accu­ra­cy is achieved when machin­ing with both spindles.

The ‘Z2’ option is avail­able on the RPT and RXU machines, as well as the RXP601DSH, RXP801, RXP950 and RXP950DSH.
