Drilling Ø 11.5 of a hole notch for a plasma cutting
machine in X2CrNiMo22, 80 mm thick. Using internal
MQL cooling and a
Lubrimat resulted in a 20 fold increase in the edge
life and savings on processing time of over 70%.
Deep hole drilling (l/d ratio = 30) of hydraulic
shafts using single-lip drills with
Toolmat. When MQL is used, the lifespan of
the drills exceeds the manufacturer's
specifications by approx. 50%. The MQL spray air
also has the useful function of blowing any
chips out of the drill hole.
Deep hole drilling with
Toolmat. Depth is over 80 times the
diameter, aluminium pump cases at a drilling
depth of 260 mm. Switching to MQL internal
lubrication trebled the edge life in comparison
to internal cooling using emulsion.
Countersinking of sheet steel 8 mm thick using Ø 20 mm
carbide countersinks, hardened subsequently. Emulsion
residues in the hardening furnace resulted
in
poor flue gas values and sooting of the furnace. With
Lubrimat®, the countersink is lubricated
using one nozzle, resulting in an edge life of 10,000
drill holes.
Countersinking (90°) of door furniture constructed of
St37 (cold rolled) with coated HSS (high-performance
speed cutting steel) countersinks. With
Lubrimat® the lifespan of the machinery
rose to 40,000 countersinks compared to 10,000 for dry
processing.
