HOW ARE MAGNETIC CHUCKS MADE
A high-quality lifting magnet has a welded construction, never bolted. The core of a permanent magnet is composed of neodymium. An electromagnet has a heart of coil, an electropermanent magnet has both neodymium and coil inside. Get a sneak peek into our magnetically attractive production!
The “mag” in MPCO stands for magnets, and we often introduce ourselves as a producer of “magnets” — when in fact, our products are lifting magnets and magnetic chucks. The word “magnet” in its true sense should be used only for the actual magnets hidden inside our lifting/clamping devices.
HOW ARE MAGNETIC CHUCKS MADE
Making Magnetic Chucks Step by Step
1. Prepping & Machining
The first step in the manufacturing process of magnetic chucks doesn’t really differ from that of lifting magnets. Our magnetic chucks portfolio is quite large, and we use a variety of parts and materials — such as steel sheets for slats of permanent magnetic chucks, and steel & brass for magnetic pole desks. Every magnetic chuck has its detailed production documentation that determines which parts and materials need to be prepped for production.
The prepped parts go to our CNC machines where operators produce the base for a magnetic chuck. Onto the base we assemble the magnetic material — slats on permanent magnetic chucks; magnets on electro- and electropermanent magnetic chucks, closely following the magnet’s production documentation.
2. Magnetic Accessories
If the magnetic chuck has a top pole desk, we machine it and then set magnets on it as well. An assembled magnetic chuck is then subjected to finishing machining operations, gets varnished, and the process is topped off with the final production control to make sure we deliver a perfect product.
Often, magnetic chucks come with a control unit which gets installed at the end of the manufacturing process. A control unit enables the integration of the magnetic chuck and the CNC machine — so that the operator controls both machining and magnetic clamping at once.
Contrary to lifting magnets, magnetic chucks don’t require an obligatory safety check — but that certainly doesn’t mean we don’t test our magnets! We surely do: we measure the magnetic flow inside the magnet and also perform our own pull-off test.
How Long Does the Manufacturing Process Take
The entire manufacturing process takes 4–6 weeks (for both lifting magnets and magnetic chucks). That said, we keep our most popular magnets in stock for quick delivery.
At MPCO, we’re more than just manufacturers — we have our own R&D department, inventing, designing, and producing our own products. We often design customised lifting magnets and magnetic chucks. In these cases, our engineers work closely with the sales department to make sure we meet the customer’s needs and requirements perfectly. For Siemens, for example, we made lifting magnets in unusual shapes and with an adjusted switch handle. We also supply large lifting systems to large production facilities.
