1.IntroductionLaser surface cladding by powder injection has become an alternative technique to conventional methods to produce high quality, metallurgically bonded coatings on metallic substrates with low thermal load into the work piece [1]. Usually, the main objective of laser cladding is...

Want to make the most out of your investment in punch press tooling and also help ensure the longevity of your machines? Here are a few simple maintenance recommendations to follow.Generally, a tool needs to be sharpened when the radius that forms on the cutting edge is worn to between .004 in and

The basic principle of four pillar hydraulic press machine is the oil pump to delivery the hydraulic oil to the integrated cartridge valve block, the hydraulic oil will be distributed to the upper or lower chamber through the one-way valve and the relief valve, the cylinder will move under the action of high pressure oil.

Active Crowning Improves Part AccuracyThis active crowning technology can solve unpredictable press brake forming issues with sheet metal during fabrication.Though sheet metal is labeled according to its minimum yield strength, it can still be unpredictable during fabrication. For example, A36 steel
