There are three types of magnetic chucks: permanent, electro magnetic and permanent electro magnetic. Permanent magnets switch on and off through the alignment of permanent magnets within the chuck to the mild steel surface on top of the chuck. […]
As the mold industry adjusts to a global economy, American mold builders need to find ways to compete with countries that have significantly lower labor cost. […]
The rapid growth of high-speed machining in the moldmaking industry continues to be facilitated by the parallel implementation of advances in machine tools. […]
Plastic injection molds have been used for years to produce high-volume components ranging from bottle caps to dashboards. The mold bases used for this process have always been high-cost, long leadtime items. […]
In 2001, two new types of milling magnets entered the market – magnetic setup blocks and permanent milling magnets. […]
Magnetic chucks are the most flexible type of workholding system for the widest range of machine tools, including horizontal and vertical machine tools, HSM centers, CNC lathes, mills, EDM palletized robotic applications and surface grinders. […]
Employing this technology into a machine tool and spindle service program is the key to achieving overall equipment effectiveness. The right service program should utilize all available assets. It should keep a spindle running in peak condition, which allows it to maintain a high level of quality and production, through regular maintenance. […]
Consider these factors when selecting the type of magnetic chuckImposed LimitThe most obvious limit to using magnetic workholding is that some materials, such as ceramics and plastics, as well as some metals such as stainless steel, aluminum or bronze, cannot be held by a magnet. […]
When justifying the investment, it is important to complete an accurate estimate of the potential cost savings for automating an area. Robotic automation offers many direct benefits to the bottom line of the manufacturing operation. Replacing manual operations reduces obvious factors like labor cost including overtime, benefits and taxes. […]
Rule 1: Mold tolerances become more critical.As parts get smaller, any miscalculations have a significantly greater impact. When requesting a micro mold, aim for 10 percent part tolerances, as opposed to the 25 to 50 percent level commonly seen in macro molds, […]
