CX® External roller burnishing machines Product features Versatility Accurate sizing All ductile or malleable metals with hardness up to R/C 40 can be roller burnished. Cylindrical parts of any length, bars, tubing, wire and stranded cable may all be processed with Cogsdill’s self-contained, selffeeding roller burnishing machines. A continuously variable speed drive allows the operator to select the optimum production rate for obtaining the desired size and finish. An adjustable tilt base makes it possible to select the ideal feed angle for automatic or manual loading. Several sub-assembly...

CX® External roller burnishing machines CX-2000 External roller burnishing machine CX-2000 The CX-2000 External Roller Burnishing Machine offers quiet, smooth operation in a rigid and stable machine design. Two models are available: an adjustable speed model, with variable frequency drive and digital speed display; and an economical fixed speed model (which can be adjusted, if necessary). Coolant capability is standard on both models. An optional portable cabinet with integral coolant pump is offered (and recommended). The CX-2000 uses the same interchangeable race assemblies as the CX-1;...

CX® External roller burnishing machines CX-2000 External roller burnishing machine CX-2000 External Roller Burnishing Machine features product design improvements to enhance machine performance. Interchangeable race assemblies size, finish, and work-harden parts in seconds; throughfeed or up to a stop-and release. Four sub-assembly options enhance machine versatility (interference-to-astop shown). Coolant system lubricates parts and flushes away chips. When optional portable cabinet is purchased, pump comes mounted inside cabinet. CX-2000 Easy-access control panel is located on the front of...

CX® External roller burnishing machines Other CX® machine models CX-1 CX-2 The CX-1 External Roller Burnishing Machine processes parts in the same size range as the CX2000, but is designed for permanent installation on the production floor.The burnishing head is belt driven and has a continuously variable speed drive. A coolant system and drip pan are mounted on the same frame with the motor and burnishing head. The CX-1 is specifically designed for rugged high production use. The CX-1 utilizes the same race assemblies as the CX-2000 and processes parts ranging from .045 to 1.004 inches...

CX® External roller burnishing machines CX sub-assembly options The CX machine is designed for versatility. Four CX sub-assembly options allow almost any part configuration to be burnished. The machine operates in one of two modes: interference or compensating. In the interference mode, the working diameter is set slightly smaller (about .0005 inch, or .01mm) than the diameter of the workpiece. The interference mode is used to accurately size and finish parts simultaneously in one fast pass. The air pressure-controlled compensating unit allows the machine to automatically adjust to...
