H1 – lubrication system for spindles

External & internal spindle lubrication

Generates the finest aerosols that reach the tool directly via the spindle. Up to 15 nozzles and versatile control for maximum precision.

Key features & technical data

  • External and internal lubrication through the spindle channels
  • Maximum air pressure: 11 bar
  • Air inlet pressure: 4-16 bar (max. 25 bar)
  • Control air pressure: 3-8 bar
  • Viscosity (Oil): 10-60mm²/s
  • Voltage: 24V DC
  • Number of ports: 1-4
  • Number of nozzles: up to 15

The H1 system is optimal for applications where high-precision and flexible lubrication through the spindle is required, both externally and internally. The finest misting effectively protects the tool and workpiece.

H1 – air-oil lubrication through the spindle

The H1 system creates an extremely fine oil-air aerosol and delivers it through the spindle directly into the tool — either as external lubrication or as internal lubrication through the spindle channels. This brings the lubricant exactly to where it is needed at the cutting edge, even deep inside the tool. With up to 15 nozzles and one to four connections, the lubrication can be tuned finely to each operation, and because the air and oil supplies are controlled separately the system works with high precision. H1 is part of DropsA's minimum quantity lubrication range for clean, accurate machining.

How it works

H1 generates a very fine oil-air aerosol and routes it through the spindle to the tool. Where the tool has internal coolant channels, the aerosol travels through the spindle and out at the cutting edge (internal lubrication); otherwise it is applied externally. The separate control of the air and oil supplies lets the mixture be set precisely, and the air inlet pressure of 4–16 bar (max. 25 bar) drives the aerosol reliably to the cutting point. Up to 15 nozzles and one to four connections allow the supply to be matched to the machining task.

Frequently asked questions about H1

What does the H1 system do?
It creates a very fine oil-air aerosol and delivers it through the spindle directly into the tool — as external lubrication or internally through the spindle channels.
What is the difference between external and internal lubrication?
External applies the aerosol to the tool from outside; internal routes it through the spindle and out at the cutting edge, for tools with internal channels.
How finely can the lubrication be adjusted?
With up to 15 nozzles and one to four connections, plus separate air and oil control, the supply can be tuned precisely to each operation.
What air pressure does it need?
An air inlet pressure of 4–16 bar, with a maximum of 25 bar.
Where is H1 used?
In metalworking — drilling, milling and turning, especially deep-hole and through-tool operations where the lubricant must reach the cutting edge inside the tool.
