Carbide metal impregnator THE new Rocklinizer Model 800 metal impregnator from Rocklin Manufacturing deposits and impregnates wear resistant electrode materials to metal surfaces for wear prevention and maintenance. For users who require a heavier deposit (for instance on gripping applications), the Model 800 can apply up to 0.007". The portable unit, which weighs only 35lb, is supplied complete with power unit, electrode package and instruction manual. Three types of electrodes are available for use with the Rocklinizer: tungsten carbide electrodes are applied to high speed steel and other metal surfaces to prolong useful life and reduce wear; titanium carbide electrodes surface seal carbide to prevent chipping; and ‘Rockhard’ electrode material is applied to build up, to reclaim undersized tools by restoring tolerances, ERW tube mill from China AUTO-DNSA mill was developed by FD Machinery in 2011 on the basis of DNSA technology. AUTO-DNSA refers to the DNSA mill with automatic roll change and automatic adjustment. FD has signed the first supply contract with a Taiwanese large steel tube company and the mill will be put into operation in June 2012. The basics of AUTO-DNSA mill are from DNSA, which is an upgrade on the manual automation of DNSA mill. Similar to the DNSA mill, the AUTO-DNSA mill has higher requirements on the equipment precision and rigidity as compared with normal mills. The differences are that in DNSA mill, the tables are used to adjust the rolls manually The Rocklinizer features a rotary applicator for faster application, and has touch panel controls and digital readout for deposit thickness and applicator speed.

for maintenance, and to provide gripping surfaces. Deposits are available from 0.0002" to 0.007" in a single application, controllable within 0.0001" by machine setting. This is a heavier maximum deposit than any previous model. Rocklin Manufacturing Co – USA Fax: +1 712 252 5619 Email: info@rocklinmanufacturingco.com Website: www.rocklinmanufacturingco.com

and the roll changes are done mechanically. For AUTO-DNSA mill, the automatic roll change is done via programs for automatic adjustment. The roll change (including adjustment) takes less than an hour. FD Machinery – China Website: www.fdmachinery.com
