Milling chuck toolholders ensure
accuracy
Milling chuck toolholder systems have face and taper contact which provides extra rigidity, improved run-out accuracy and hence - greater process reliability - for machining precision components.
Wimbourne, UK-based Eaton Aerospace, part of the Eaton Corporation, is a market-leading provider of advanced, high-quality fuel systems, assemblies and components for the global aerospace (civil and defence) industry The company's products help manage and control fuelling and de-fuelling operations in aircraft - (transferring fuel from fuel tanks to engines and auxiliary power units - and the jettison of fuel)

Nikken Kosakusho UK were approached by 'IPE', a leading Aerospace manufacturer which was looking to ramp up production using an existing Matsuura RA1, twin pallet, machining centre.
Increase productivity from existing machines
If UK manufacturing companies are keen to increase productivity and output, they must move away from age-old methods and processes in work- and tool- holding when using metal cutting machine tools.
The company's fluid conveyance systems are used extensively by the world's aircraft manufacturers (OEMs) and airforces - and Eaton Aerospace's customers and applications include Airbus (A380), Boeing (787 Dreamliner) and Lockheed Martin (F-35 Joint Strike Fighter) etc The company, formerly known as FR- HiTemp, part of the Cobham Group - was acquired by Eaton in September 2005 - and its people, machinery, skills and expertise are all due to be relocated to Eaton's Fluid Power Group facility in Titchfield (Hampshire) over the next few months.
Eaton Aerospace designs and manufactures performance critical components.
Manufactured in the majority of instances from aluminium - these parts are machined to extremely tight tolerances (typically +/-0.002in down to +/-0.001in) and exhibit excellent surface finishes (0.8 micron Ra or better).

Nikken Kosakusho UK is the sole UK distributor for the Elbo Controlli range of presetting machines, high precision tool presetting equipment that were previously supported by Stellram UK.
Tool presetter also performs inspection
Dual function camera system provides tool presetting and tool inspection on a tool presetter fitted with vacuum clamping with index lock on an interchangeable spindle.
Frontline distribution catalogue imminent
From 1 November 2004 Nikken Kosakusho UK will be launching the new Frontline Distribution Catalogue.
To achieve these results the company invests (and continues to re-invest) in the very latest, high-performance machine tools and ancillary equipment.
As part of its investment and best practice strategies - the company has recently turned to leading Rotary Table and NC Tooling specialist - Nikken - to supply tooling for its two Mori Seiki (NH 5000) twin-pallet, 14,000 rev/min horizontal machining centres used to manufacture aluminium complex parts that include MFLI (Magnetic Fluid Level Indicator) components for the Airbus 380.
The 3-Lock Slim Chuck and Milling Chuck (MBT 40) toolholder systems supplied by Nikken provide Eaton Aerospace with the optimum machining solution.
These toolholder systems have face and taper contact which provides extra rigidity, improved run-out accuracy and hence - greater process reliability.
As a consequence they provide Eaton Aerospace with the part accuracies, repeatabilities and surface finishes required on these components - and, owing to their unrivalled dampening characteristics, increase cutting tool performance and tool life too.
Said Steve Clarke, production engineer at Eaton Aerospace: "Before we invested in the Nikken toolholders - we could not get the results we required.
We were attempting to achieve tight tolerances and high surface finishes using shrinkfit tooling - but found this solution unsatisfactory in terms of part accuracy, finish, cutting speeds and tool life." He said: "The parts we manufacture are complex and lead times are always tight." Clarke added: "The parts necessitate, amongst other machining requirements, frequent and highly-accurate deep drilling and boring operations to be performed with minimum operator intervention.
As such we need cost-effective tooling solutions that can be relied upon to deliver - day in -day out." He concluded: "The Nikken Slim Chuck and Milling Chuck solutions give us what we need.
They have eliminated time spent on reworking parts - and, because of their extra rigidity and stability - part accuracy, finish and cutting tool life are all significantly increased.".
