To meet the demands of todays customers each and every plan has to include getting the pieces on and off machines as quickly as possible along with allowing a cutting tool access to areas of the work that need to be machined, and achieving consistent holding pressure on the work pieces and ensuring adequate safety.
Constant evaluation to the best approach to work holding should be done by the mold makers using Magnetic Chuck China. On the use of traditional clamping and fixturing methods, Users of CNC machining centers and milling machines are totally relying on, which before an actual machining operation begins to require significant setup time.
The production of multiple parts or parts of varying dimensions is involved in a machining or milling operation involves, the amount of setup time increases exponentially based on number, size, and required orientation of parts and there is an overall reduction in the operation's total productivity. For users to reduce setup time and increase productivity the use of magnetic devices is a highly versatile work holding alternative.
For the widest range of machine tools, the most flexible type of work-holding system are horizontal and vertical machine tools, CNC lathes, mills, EDM palletized robotic applications, HSM centers, and surface grinders, magnetic chucks. Because of usage versatility, they are most flexible. Compared to mechanical fastening or clamping, the use of magnetic chucks to affix workpieces to the machining table or surface saves time.
Workpieces are manually attached to the bed with the use of holding clamps or vises that must bescrewed down or secured as part of the machine setup to ensure firm and accurate positioning of the workpiece according to the machines CNC program. If a mold maker wants to machine multiple parts with one setup or several parts of varying dimensions, magnetic chucks are more flexible or accommodating.
To prepare for the machining process versus the use of magnetic work holding each of these scenarios would require much more setup time. Compared to vacuum work holding, they are more flexible, meaning capable, because the holding power of the magnet can exceed the suction force created by the vacuum, which is very much beneficial for machining large-size parts.
However, setting up with Magnetic Chuck China requires a mask to seal any holes that are not directly covered by the mounted workpiece.
Permanent-magnetic Chucks
Permanent-magnetic chucks constitute two matching packs of magnetic materials. To direct the magnetic force through the top plate and into the workpiece a mechanical lever aligns the packs. When the lever reverses the workpiece is released and the magnetic forces are contained within the chuck.
Electromagnetic Chucks
DC voltage is used in Electromagnetic chucks that to in a coil surrounding mild-steel pole pieces. As long as the voltage is applied the poles are magnetic. Variable holding power is provided by electromagnetic chucks, which greatly improves their ability to support a wide range of machining conditions. To automate the operation interfacing capabilities with machining centers make it easier.
The most widely used rare-earth magnets are Neodymium magnets.
Made from iron, boron and neodymium alloy, they are permanent magnets like Magnetic Chuck that are to form a tetragonal crystalline structure.
Today as hard disk drives, fasteners and even in motors, you will find the magnets in cordless tools.
Below are Few of the common uses of neodymium magnets are as below.Iron industry uses - in iron industries, these magnets are used especially in lifting huge iron materials from iron dust whereas dust particles are attracted by the weaker magnets.
The magnets are also used as magnetic separators and lift large ferrous items in heavy engineering and manufacturing industries.Medical industry uses - for magno-therapy, the neodymium magnets are used by medical physiotherapists and practitioners extensively to decrease pain.
To wear as bracelets, blankets and shoe insertions, they are also sold as medical devices.Entertainment industry uses - in audio equipment like acoustic pick-ups, microphones, speakers, and headphones, the permanent magnets are used when it comes to the entertainment industry.Home uses - in various ways, such as in hanging pictures, fixing furniture and creating drawer and door closures, the neodymium magnets are used at home.
