A few notes on these numbers:<\/p>\n\n\n\n

Wire tension is deliberately lower than for NdFeB.<\/strong> We typically run ferrite at 100\u2013130 N versus 100\u2013150 N for NdFeB. The reason is crack sensitivity \u2014 higher tension increases the cutting force at each diamond grit contact point, which on ferrite can exceed the fracture threshold and initiate subsurface cracks. If you\u2019re seeing micro-cracks on your cut surfaces (visible under 20\u00d7 magnification as fine lines running perpendicular to the cut direction), reducing tension in 10 N increments is the first adjustment to make.<\/p>\n\n\n\n

Feed rate has a sharp quality threshold.<\/strong> With NdFeB, surface quality degrades gradually as feed rate increases. With ferrite, there\u2019s often a more abrupt transition. Below 2 mm\/min, surfaces are clean with minimal chipping. Push to 3 mm\/min and chipping rate jumps noticeably. Push to 4+ mm\/min and you start getting subsurface cracks. The exact threshold depends on block cross-section, grain alignment direction, and wire condition, but the pattern is consistent: ferrite rewards conservative feed rates more than most other materials.<\/p>\n\n\n\n

Water-based coolant is standard.<\/strong> Since ferrite is chemically inert to water, there\u2019s no need for oil-based coolant. Water-based coolant actually works better for ferrite because it dissipates heat more efficiently and produces a cleaner cutting zone \u2014 the ferrite dust particles wash away easily rather than forming a sludge with oil. This also simplifies post-cutting cleanup significantly compared to NdFeB processing.<\/p>\n\n\n\n

Crack Prevention: The Central Challenge<\/h2>\n\n\n\n

If there\u2019s one thing that distinguishes ferrite cutting from all other magnet materials, it\u2019s the crack sensitivity. Understanding how cracks form and propagate during diamond wire cutting is essential for maintaining acceptable yield rates.<\/p>\n\n\n\n

Cracks in wire-cut ferrite originate from two mechanisms:<\/p>\n\n\n\n

Mechanism 1: Tensile stress at the wire exit.<\/strong> As the diamond wire reaches the bottom edge of the workpiece, the remaining material bridge thins to the point where it can\u2019t support the cutting load. Instead of being cut cleanly, the last fraction of material fractures \u2014 often creating a chip or initiating a crack that runs back into the body. This is the same mechanism that causes exit-side chipping in all brittle materials, but ferrite\u2019s low fracture toughness makes it worse.<\/p>\n\n\n\n

Prevention:<\/strong> Reduce feed rate for the last 2\u20133 mm of each cut. On our machines, we program a two-stage feed profile: normal feed rate for the bulk of the cut, then 50% reduction for the exit zone. Some operators also use a sacrificial backing plate \u2014 adhesive-bonded to the bottom of the workpiece \u2014 that provides material support through the exit zone. This approach is borrowed from wafer dicing<\/a> \uc587\uc740 \ud398\ub77c\uc774\ud2b8 \uc870\uac01\uc5d0 \ud6a8\uacfc\uc801\uc785\ub2c8\ub2e4.<\/p>\n\n\n\n
