Wide Single Knuckle Joint Press

Knuckle joint presses operate with a knuckle mechanism for slide driving and operate very slowly in the vicinity of bottom dead center with a unique motion curve and are suitable for precision machining.
The JNKJ-W series is a zero clearance slide adjustment device for heavy plate blanking and necking, embossing.
It is a special grade knuckle press which is specially designed to maintain optimum precision in machining such as burring.

At the point of tonnage rating, it keeps pressing to optimize forging productions as well as the cut-face is very excellent.

▪ HIGH STRENGTH FRAME : It is designed strong enough to stand concerated stress on the center of frame when compressing
▪ USE SPECIAL MEDAL ON THE LINK PART: It is guaranted for long life expentacny by using specialized-alloy-metal
▪ LOCKING DEVICE: Zero clearance of locking device to realize the zero clearance on the part of slide adjust
▪ EXTERNAL TYPE OF AIR CLUTCH BREAK: It is easy maintenance as outer-mounted air cluth
▪ AUTO LUBRICATION OR OIL FEEDING: It feeds proper oil or lubrication to PRESS at the same time PRESS operates.
▪ LOWER KNOCK: There are four (4) types of knock outs like Mechanical, Hydraulic and Pneumatic type. (It is optional as customers’ request)
