Internal Coolant Supply

Application description
The internal coolant supply through cooling channels present in tools, is particularly essential nowadays when working with high-grade materials and complicated components in modern manufacturing. The rapidly increasing cutting speeds in HSC processing, and the continuously decreasing diameters of deep hole drilling requires quick heat dissipation and safe removal of the chips. In order to insure this process at increasingly higher speeds and pressures, rotary unions are necessary that deliver the various cooling agents, like emulsion, oil, oil-air mixture or dry air, to the spindle shaft, by way of the permanently advanced sealing systems.

Product guide
Single channel System, axial mounting
ROTODISK S
Hydrostatically released and dry operation safe contact seals for safely transmitting coolant, oil, Oil-Air mixture or air. It will not leak upon shutting off the coolant supply.
Single channel System, radial feed
ROTODISK SW
Rotary union with durable contact seals, hydrostatically released, compact design for installation on driven tools.
Multi-channel System, integrated Installation
ROTOSTAT
Non-contact sealing system for high pressures and very high flow rates with very little leakage at the same time. The sealing system, which almost does not wear out, guarantees a very long product life.
