Magnetic chucks allow for more machining in the one set-up

When it comes to workholding, any product that can offer productivity gains is certainly welcome news and is one of the primary reasons why magnetic chucks are increasing in popularity.

These chucks offer a number of benefits to operators of CNC milling machines.
Dimac Tooling, Australia and New Zealand’s leading supplier of accessories and workholding solutions for CNC milling and CNC turning machine tools is the sole distributor for the Eron range of magnetic chucks.
Very few companies in the world today can boast such a rich engineering history as Nabeya Eron.
The company was formed in 1560 and were famous for such products as temple bells, Samurai swords and cooking utensils. Today they are still a major foundry in Japan while also specialising in machine tool workholding equipment.
“Unlike conventional chucks, Eron magnetic chucks allow heavy duty machining of the entire surface area and sides of the workpiece in one setup; especially beneficial for 5 sided machining. Plus the set up of the chucks is extremely fast; place the part and flick a switch, that’s all,” said Dimac Managing Director, Paul Fowler.
“They are ideal for distributing clamping force over the entire workpiece unlike a vise so less part distortion is a feature,” Mr Fowler added.
The workpiece is fixed by a powerful 6150N magnetic force using Neodymium magnets. Magnetism flows from the North magnetic pole within the workpiece, and therefore chips are not attracted to the surface of the workpiece.
Magnetic chucks also prevent the infiltration of metal working coolant. Resin and brass are not used on the top surface that the workpiece is placed on. The surface is completely metal, preventing infiltration of metal working coolant and increasing durability.
Both vertical and horizontal chucks are available and an electronic controller is included with all chucks.
“Another benefit is that permanent electromagnetic chucks have the ability to maintain clamping force even after the power cable has been disconnected. Furthermore, since the workpiece is clamped from underneath, there is no need to worry about interference with cutting tools,” Mr Fowler went on to say.
Optional peripheral devices are available, including a Magnetic Height Block which protects the top surface of the magnetic chuck whilst improving the precision of the top surface of the magnetic chuck. The Mag-work Support, allows support of  uneven workpieces eliminating chatter.
“Eron Magnetic chucks are built to an uncompromising standard with cutting edge design and superior materials that make them a very logical choice for increasing productivity and quality,” Mr Fowler said.
“Like all the products we sell, Eron Magnetic chucks have the full back up and support of Dimac technical personnel to ensure the products are installed correctly and operate at optimum performance,” Mr Fowler concluded.
