Manufacturing Technology

With the growing interest in reshoring and making components locally, both in Europe and across the world, as well as the growing importance of sustainability within the cold forming process, National Machinery states its machine portfolio can meet the needs of customers. 

Amongst the solutions from National Machinery is the FXH Lightning, a double stroke single die header that is available in two sizes, which provides more uptime, fast changeovers and effective ergonomics. “Customers get more uptime from National dependability, quick tool changing, easy adjustments and simple maintenance,” mentions National Machinery. “The FXH also includes a unique slide guiding system, precise linear feed, fine adjustment of kick and feed – while running along with rigid punch rocker locking – to produce consistent quality parts.”

National Machinery points out that the precision linear feed system is so accurate that there is no need for a stock gauge. Plus, there are no parts to change for most wire sizes and feed length adjustment only takes seconds with the automated adjustment. It also eliminates over feeding and feed roll slipping that can damage the wire.

Other features include the motorised adjustment of feed and kick allowing the operator to perform other tasks while the machine is adjusting. In addition, the mechanism adjusts to preset values and fine adjustments can be made while running. To add to this, the die block cap clamps just the die, not the quill, and removes quickly for die change; there is no wedge to affect the close tolerance slide guiding system; and the quick clamp quill position is repeatable requiring no in-machine alignment. 

In addition, the transfer can be pre-set on a fixture outside the machine and the transfer bar is adjustable to the transfer fixture for quick and repeatable changeover. Both punches also mount on the oscillating punch rocker, and mechanical locking and precise slide alignment during both forming blows results in exceptional concentricity and tool life.  Finally, the thick wall punch holders extend punch holder life.

“Localisation is a great way to support sustainability to minimise logistics and inventory,” explains National Machinery. “The small footprint of the machine, in combination with the production speeds of up to 470 parts per minute, make for an efficient use of space and the ‘lightning fast’ speed of the header can make it a key factor in localisation for lots of customers.”
