Turning
ISCAR has developed a new concept for high
pressure coolant supply for VDI DIN 69880 quick-
change adaptation systems, intended for turning
machine tools. The JETCUT concept is based on
bottom-fed high pressure coolant channels and
provides coolant supply internally through the tool and
externally through the flange.
A wet coolant can act as an excellent tool in a radically
different field: increasing the rotational speed of a
tool. ISCAR’s SPINJET family of coolant-driven high
speed compact spindles for small diameter tools helps
upgrade existing machines to high speed performers.
The SPINJET spindles are recommended for tools
up to 7 mm (.275 in) in diameter; however the optimal
diameter range is 0.5-4 mm (.020-.157 in). Depending
on pressure and coolant flow rate, the spindles
maintain a rotational speed of up to 55000 rpm.
Reaming
In reaming, floating chucks are used in high-precision
hole making to correct any misalignment between the
central axes of a reamer and a hole. Precise alignment
is essential for optimal performance and hole
accuracy. To this end, ISCAR added a new design of
GFIS floating chucks for high speed reamers to the
ER COLLET chuck family.
