GYRO - Radial and Angular Alignment Toolholder

Adjustable Toolholder for Easy Adjustment
of Radial and Angular Misalignment T.I.R. max. 0.02
Application
Gyro is a rugged and adjustable toolholder developed
by ISCAR/ETM to solve drilling, tapping and reaming
problems encountered on CNC and turret lathes.
Its unique design allows smooth and easy adjustment of
radial and angular misalignment between chuck
and turret.
Angular Adj. 1º
Gyro reduces total machining time by making it possible
to complete machining of holes in one drilling step and
to achieve tolerances as close as 0.01 mm, thereby Radial Adj. D2.0
eliminating subsequent boring or reaming operations.
• A breakthrough in drilling technology for CNC lathes
• Dramatic increase in tool performance at reduced cost

Features
• Enables high precision drilling to a close tolerance
of h6, to be performed as a final boring operation
on CNC lathes
• Reduces machining time by completing the bore
in one drilling step, eliminating secondary turning
and boring operations
• Prolongs cutting tool life tenfold and more, especially
for high performance HSS, solid and brazed
carbide drills, center drills, taps and reamers
• Dramatic increase in speed and feed by up to 300%.
• Coolant supply through the shank center of
the tool shoulder for oil hole cutting tools

1. Radial adjustment screw

• Easy adjustment for correcting misalignment between 3. Angular set ring
chuck and turret axis (drill and workpiece) 4. Front part
• Precise and efficient tool clamping with ER collets 5. Alignment test bar
and ER sealed Coolit Jet collets 6. Test bushing
• Quick functional adjustment is made on machine 7. ER nut
by using ISCAR/ETM plug and ring gauge kit 8. Coolant connection
Operation
For operation instructions see the brochure
packed with the tool.
Notes
• Coolant supply should be minimum 10 bar and maximum
80 bar for small diameter oil hole drills ranging from 3-20
A soft material bar should be
used to test the bar diameter mm. (the normal machine pressure of 4 bar is insufficient).
for the alignment procedure. • Coolant filtration is most important to eliminate
chips from blocking the drill oil hole.
• To ensure maximum performance of the GYRO,
the backlash of the turret indexing and support
axis mechanism should be checked and readjusted
according to the machine standard.

Test bar
First time users should buy a GYRO kit which includes a test
bar and a bushing for performing the alignment procedure.
