An electric press brake is not typically found in a metal fabricating operation, but that is changing as more companies realize the accuracy, speed, and energy savings that this type of device offers.
For fabricators looking to reduce the amount of lubricant they use for sawing applications, lubricants designed for near- dry sawing may be the answer. These minimum quantity lubricants, as they are called, are designed to provide complete coverage of the blade with as small an amount as possible.
When designing and operating a robotic welding cell, don't overlook the consumables. Choosing the wrong consumables can over time lead to serious costs.
A process called TIP TIG uses a constant-feed hot-wire that imparts additional energy to the weld. The wire also is superimposed by a secondary high-speed oscillation. The hot-wire’s current combines with the weld-pool agitation to disrupt the surface tension and change the weld dynamics.
Within electric brakes, bending force is distributed differently. Also optoelectronic safeguards integrate closely with the control, so much so that a light curtain or similar device has no effect on the bending cycle time. In fact, in the electric press brake arena, safety does not necessarily require a sacrifice in cycle time.
When a welder is not welding, he's not making the company money. Fabricating operations can't afford their welding departments. Luckily, several reasons for extended arc-off time can be addressed with some simple adjustments.
Switzerland’s manufacturers have no trouble finding citizens with technical skills; there just aren’t enough Swiss citizens. The country has a comprehensive apprenticeship program that helps prepare students for the working world.
Midbrook, a Michigan fabricator of washing equipment, has worked hard to diversify outside of the automotive business. One key to its success has been its approach to selling to health care facilities. The fabricator has decided to circumvent traditional distributorship networks in health care.
High-product-mix manufacturers may have problems with off-theshelf TOC, as described in Eliyahu Goldratt’s The Goal, a book that tells how a fictional company manages its operations around a constraint. In a high-mix, low-volume operation, the constraint actually may move around from job to job, because processing
Manufacturing companies, both large and small, complain that they can't find skilled workers to fill open positions. Instead of waiting for local educational institutions to change their ways, they might have to assume more training responsibility, and e-learning tools can help them do just that.
Columnist Gerald Davis offers fabricators guidance in dealing with an engineering change order to a 3-D CAD model.
