While some machinists treat it &#8220;exactly the same as 6061,&#8221; a nuanced approach yields superior tool life, finish, and efficiency. The goal is to generate clean, broken chips and manage heat effectively.<\/p>\n<p>For cutting speeds (SFM), a robust starting point is 300\u2013500 SFM for carbide end mills. You can often push towards the higher end of this range with sharp, polished tools and ample coolant. However, if you encounter gummy behavior\u2014particularly with softer tempers like T7351\u2014dropping to the 235\u2013300 SFM range while increasing feed per tooth can help shear the material more cleanly rather than rubbing it. As one user experimenting with T7351 found, &#8220;running the tool slower (235 sfm) with faster feeds seems to work a little better.&#8221; The key is maintaining an aggressive chip load; a feed per tooth (IPT) between 0.004&#8243; and 0.012&#8243; is typical, with higher feeds within that range helping to promote chip evacuation and reduce heat buildup in the cut.<\/p>\n<p>Tool selection is non-negotiable. High-quality, sharp carbide end mills with 2 or 3 flutes are standard. Tools specifically designed for aluminum feature high helix angles (around 38-45 degrees) and polished flutes to prevent chip welding. Coatings like zirconium nitride (ZrN) or uncoated, polished carbide are excellent choices to minimize aluminum adhesion. Drills should be carbide-tipped or solid carbide with a high point angle (130-140 degrees) and polished flutes. For all tools, rigidity is paramount; use the shortest flute length and largest diameter shank possible to combat deflection, which can mar surface finish and accelerate tool wear.<\/p>\n<p>Coolant application is not just beneficial\u2014it&#8217;s critical. Use a flood of water-soluble coolant to manage heat, wash away chips, and prevent re-cutting. For operations where flood coolant isn&#8217;t feasible, a powerful air blast with a mist lubricant can be an alternative, though flood is preferred for optimal tool life and surface finish in <strong>7075 \uc54c\ub8e8\ubbf8\ub284 \uac00\uacf5<\/strong>.<\/p>\n<h2>Best Practices for Fixturing and Workholding to Minimize Deformation<\/h2>\n<p>The high residual stresses locked within 7075-T6 and T651 plate can be your greatest adversary when holding tight tolerances. As material is removed, these stresses rebalance, causing the part to warp, twist, or bow\u2014sometimes dramatically. The fixturing strategy must work to both restrain the part and manage stress relief.<\/p>\n<p>First, understand the stock. Whenever possible, specify stress-relieved plate (often denoted as T651, which is solution heat-treated, stretched to relieve stress, and artificially aged). This provides a more stable starting point than non-stretched material. Even with stress-relieved stock, a strategic approach to machining sequence is vital. The core principle is to remove material symmetrically and in balanced stages. Avoid hogging out one entire side of a pocket or wall while leaving the opposite side thick; instead, take alternating, even passes from both sides to allow stresses to equalize incrementally.<\/p>\n<p>Fixturing must provide uniform, distributed clamping force. Use a network of clamps or a vacuum chuck to spread pressure across the workpiece, avoiding isolated points of high stress that can induce distortion when released. For thin-walled or delicate features, machine them in the final finishing pass after the bulk of the material has been removed and the part has had a chance to &#8220;move.&#8221; In some cases, it may be necessary to rough the part, unclamp it to allow it to relax, then re-fixture and take a light finishing pass to hit final dimensions.<\/p>\n<p>For long, slender parts (like the mentioned 1000x70x25mm stock), additional intermediate supports are essential. Use adjustable jack screws or custom soft jaws with raised supports along the entire length to prevent sagging from its own weight or clamping pressure. The goal is to fixture the part in a state as close to its free, unstressed condition as possible.<\/p>\n<h2>Advanced Techniques: Drilling, Tapping, and Achieving Superior Surface Finishes<\/h2>\n<p>Drilling and tapping 7075 require specific techniques to avoid tool seizure, poor thread quality, and broken tools. For drilling, pecking cycles are your friend, especially for depths beyond 3x diameter. This ensures chips are cleared and coolant reaches the cutting edge. A dwell at the bottom of each peck can help break the chip. For through-holes, reduce feed slightly as the drill exits to prevent breakout burrs and potential grabbing.<\/p>\n<p>Tapping 7075 can be straightforward with the right preparation. Always use a spiral-point (gun) tap for through-holes or a spiral-flute tap for blind holes to efficiently evacuate chips. The tap must be sharp and designed for aluminum. A tapping fluid or high-lubricity coolant is recommended. For critical threads, consider thread milling. This CNC technique uses a rotating end mill to generate the thread profile, offering exceptional control, no axial tool pressure (reducing breakage risk), and the ability to use the same tool for multiple hole sizes. It is highly effective for <strong>7075 \uc54c\ub8e8\ubbf8\ub284 \uac00\uacf5<\/strong> where thread quality is paramount.<\/p>\n<p>Achieving a superior surface finish often comes down to the final passes. For milled surfaces, use a light finishing pass (0.005&#8243;\u20130.015&#8243; depth of cut) with a high spindle speed and a consistent, moderate feed rate. Climb milling is almost always preferred for aluminum as it produces a cleaner cut by shearing the chip away from the finished surface. Tool runout must be minimized; a wobbling tool will leave visible witness lines. For a near-mirror finish, consider using a single-purpose, sharp finishing end mill and potentially increasing the SFM while slightly reducing the feed per tooth for a finer cusp height.<\/p>\n<p>\ub514\ubc84\ub9c1\uc740 \ucd5c\uc885\uc801\uc774\uace0 \uc911\uc694\ud55c \ub2e8\uacc4\uc785\ub2c8\ub2e4. 7075\uc758 \uc778\uc131\uc740 \uc644\uace0\ud55c \ubc84\ub97c \uc0dd\uc131\ud560 \uc218 \uc788\uc2b5\ub2c8\ub2e4. \uc2a4\ud06c\ub808\uc774\ud37c\ub098 \uc904\uc744 \uc0ac\uc6a9\ud55c \uc218\ub3d9 \uc81c\uac70\ub3c4 \ud6a8\uacfc\uac00 \uc788\uc9c0\ub9cc, \uc0dd\uc0b0 \ud658\uacbd\uc5d0\uc11c\ub294 \uc5f4\uc5d0\ub108\uc9c0 \ubc29\uc2dd(TEM)\uc774\ub098 \uadf9\uc800\uc628 \ub514\ubc84\ub9c1\uc744 \ud1b5\ud574 \ubaa8\uc11c\ub9ac\ub97c \uc190\uc0c1\uc2dc\ud0a4\uac70\ub098 \uacf5\ucc28\uc5d0 \uc601\ud5a5\uc744 \uc8fc\uc9c0 \uc54a\uc73c\uba74\uc11c \ubcf5\uc7a1\ud55c \ubd80\ud488\uc758 \ubc84\ub97c \ud6a8\uc728\uc801\uc73c\ub85c \uc81c\uac70\ud560 \uc218 \uc788\uc2b5\ub2c8\ub2e4.<\/p>\n<h2>7075 \ubd80\ud488\uc758 \uc5f4\ucc98\ub9ac \ubc0f \ud6c4\ucc98\ub9ac \uace0\ub824 \uc0ac\ud56d<\/h2>\n<p>7075\ub294 \uc5f4\ucc98\ub9ac \uac00\ub2a5\ud55c \ud569\uae08\uc774\uba70, \uadf8 \ud15c\ud37c(temper)\ub97c \uc774\ud574\ud558\ub294 \uac83\uc740 \uac00\uacf5\uacfc \ucd5c\uc885 \ubd80\ud488 \uc131\ub2a5 \ubaa8\ub450\uc5d0 \uc911\uc694\ud569\ub2c8\ub2e4. \uac00\uc7a5 \uc77c\ubc18\uc801\uc778 \ud15c\ud37c\ub294 T6(\uc6a9\uccb4\ud654 \uc5f4\ucc98\ub9ac \ud6c4 \ucd5c\ub300 \uac15\ub3c4\uae4c\uc9c0 \uc778\uacf5 \uc2dc\ud6a8 \ucc98\ub9ac)\uc785\ub2c8\ub2e4. \uadf8\ub7ec\ub098 \uc9c0\uc2dd \ubca0\uc774\uc2a4\uc5d0\uc11c \uc5b8\uae09\ud55c \ubc14\uc640 \uac19\uc774, \u201c7075\uc758 T7351 \ud15c\ud37c\ub294 T651 \ud15c\ud37c\ubcf4\ub2e4 10% \uc774\uc0c1 \ub354 \ubb34\ub974\uace0 \uc57d\ud569\ub2c8\ub2e4.\u201d \uc774\ub294 \uc911\uc694\ud55c \uc810\uc744 \uac15\uc870\ud569\ub2c8\ub2e4. \ubaa8\ub4e0 7075\uac00 \ub3d9\uc77c\ud558\uc9c0\ub294 \uc54a\ub2e4\ub294 \uac83\uc785\ub2c8\ub2e4.
