The new boring system from leading joint integrity specialist Hydratight
addresses the time-consuming problem faced by companies needing to undertake
machinery boring work during the maintenance season. The machinery boring requirement
forces companies to take expensive machinery out of service and into a
conventional machine shop for extended periods.
Hydratight introduces the new 2250P boring bar as a solution for
companies to use during the upcoming maintenance season. Utilising a rigid,
feed screw design to feed the cutting tool along the boring bar, the boring bar
provides advanced and highly customisable machining solutions, which help to
maximise on-site machining capabilities.
Recommended for use in a wide range of industries including
construction, agriculture, mining, power generation and petrochemical where
precision is critical in any boring application, Hydratight’s 2250P boring bar is
ideal for excavator bucket support pin bores, pad eyes, camshaft/crankshaft
bearing bores, turbine seal rings and various types of valve seats, minimising
downtime by avoiding the need to take large machinery to a shop to get boring
work done.
Hydratight’s proven design ensures a vibration-free setup by allowing
the support bearings to be securely attached to the boring bar. This method of
feeding allows for long accurate bores to be machined on-site in a single
set-up, with more stability and accuracy than less rigid push-pull boring
systems.
Several design elements of the Hydratight’s 2250P boring bar are
inspired by the larger capacity field proven Hydratight 8200 series machines,
including the rotational drive unit; the assembly uses a 5:1 double enveloping worm
gear, which provides 25 per cent more cutting torque than any other boring bar
within its class. The boring bar’s robust assembly has hydraulic, pneumatic and
electric drive capability options.
Hydratight APAC Leader, Mr Dean Jenkins observes that the boring bar is
a great way to increase efficiency and eliminate downtime. Further efficiency
can be achieved with the bore welder and the boring bar assembly utilising the
same support system, which allows the bar to be pulled after centring so that
the bore welder can quickly be inserted into the 2250P bearing support to begin
the welding process.
Key features of Hydratight’s 2250P boring bar include choice of bar
lengths starting at 1.22m up to 3.66m with 1.27cm broached tooling holes every
15.24cm; bar centred within a bore using the available rapid traverse centring
cones that quickly align the bar and bore; final precision radial adjustment allowed
up to 0.635cm using jacking bolts within the support assembly; and end supports
designed with multiple mount options with each support fitted with a spherical
bearing allowing for up to 5 degrees of bar alignment.
Hydratight’s 2250P boring bar offers multiple benefits including 25%
more cutting torque than other boring bars in its class; boring heads equipped with
fine radial adjustment for faster set-up; and assemblies mounted at any point
along the bar, providing flexibility to cover most boring or facing
applications.
