ETG gets to grips with Buck Chucks!

ETG gets to grips with Buck Chucks!

Added to MTDCNC by ETG on 26 October 2015

ETG Workholding, the dedicated division within the Engineering Technology Group with the UK’s largest portfolio of workholding and specialist metal cutting accessories now offers the comprehensive range of Buck Chucks which are available in manual, powered and high precision options.


For over 75 years Buck Chuck USA has engineered and built high quality workholding products. Now part of the Hardinge Group, Buck Chucks legacy products are the ATSC and AT Ajust-Tru self-centring manual scroll chucks alongside high precision and power chucks.


Most recently it has expanded its range with introduction of a new ATSC range and improvements to the AT products.


ATSC now features micro-fine adjustment to allow .0005" TIR repeatability and a high quality forged steel body construction to allow for higher lathe speeds.


The hardened and ground scroll is now precision balanced allowing longer life and greater accuracy.


The upgraded AT chuck is based on the much copied Buck Chuck Ajust-Tru design with the new upgrade featuring a larger through hole and higher-quality cast iron workpiece material.  AT semi-steel body manual scroll chucks are available in 3 and 6 jaw master and top reversible options.


All steel bodied ATSC products are made to strict ISO standards and have the Buck Chuck trademarked Ajust-Tru feature.


Finally, for extra heavy duty applications there is a range of 3 jaw scroll or 4 jaw independent style oil country chucks available in 25” (89cm) to 80” (100 cm) capacities with solid or American standard tongue and groove jaws.  For internal and external chucking operations, oil country chucks are available in steel or cast iron body specifications.


The addition of Buck Chucks to the ETG Workholding range complements the existing collet systems available which include the Hardinge FlexC quick change system and the Hardinge traditional style C style collet chuck.
