What These Brackets Are and Why the Tolerance Beats Casting These are load-bearing CNC Machined Furniture Brackets cut from solid aluminum or steel, not cast or stamped. You get a flatness of 0.02 mm
These are load-bearing CNC Machined Furniture Brackets cut from solid aluminum or steel, not cast or stamped. You get a flatness of 0.02 mm across the mounting face and hole-to-hole tolerance of ±0.01 mm. That means your drawer slides align perfectly, your table legs sit flush, and your frame joints never creak under 300 kg of static load. We machine them on 3-axis and 5-axis centers, deburr every edge, and ship in 10 days for standard sizes.
This is precision manufacturing from our Dongguan factory with 20 years of export experience. We are not a job shop that batches parts when it feels like it. We run a 4,000 square meter floor with 32 CNC machines, and furniture brackets make up 20% of our output. You get a bracket that fits the first time, no rework on your assembly line.
Furniture brackets often have lightening pockets, cable routing slots, or hidden screw bosses. Chatter marks on those surfaces are ugly and weaken the metal. We use variable-flute end mills and climb milling at 12,000 RPM spindle speed, which keeps the surface finish at Ra 0.8 µm. For aluminum 6061, we run a chip load of 0.05 mm per tooth, and for stainless steel 304, we drop to 0.03 mm.
Our toolpath strategy is adaptive clearing, not linear raster. This reduces tool deflection to under 0.005 mm. If you design a thin web between two pockets, we hold that wall to 1.5 mm thickness without warping. Check out our CNC cutting tool selection guide to see why tool geometry matters more than spindle power for this type of work.
You are not limited to soft aluminum. We machine these brackets in five standard material groups: 6061-T6 aluminum (yield 276 MPa), 7075-T7351 aluminum (yield 435 MPa), 304 stainless steel (hardness 78 HRB), 12L14 free-cutting steel, and S45C medium carbon steel. For high-wear hinges or pivot points, we offer heat treatment to 45-52 HRC on steel brackets.
Hard anodizing is available up to 60 µm thickness on aluminum, which passes a 500-hour salt spray test. We do not heat treat aluminum brackets because that would ruin the T6 temper. Instead, we stress-relieve the aluminum blanks at 190°C for 4 hours before machining to prevent distortion after you weld or bolt them.
Every batch of CNC Machined Furniture Brackets goes through a 3-point inspection. First, we run 100% dimensional check on critical holes using a CMM with 0.001 mm resolution. Second, we place each bracket on a granite surface plate and check flatness with a 0.01 mm feeler gauge. Third, we torque-test one bracket per 50 pieces to verify that the screw bosses withstand 8 N·m without cracking.
We send you a full inspection report with the shipment, including the material certificate and the CMM data points. If you need PPAP level 3 documentation, we do that too, but it adds 2 days to the lead time. For repeat orders, we keep your inspection fixtures in storage for 5 years, so your next order is checked against the same datum structure.
Furniture brackets are often long and thin, like a 500 mm support rail. That is where tolerance stacking kills you. We machine the datum surface first, then reference all other holes off that same datum. This keeps perpendicularity at 0.03 mm over a 300 mm length. If your bracket has a 90-degree bent corner, we do not bend it. We machine it from a solid block to avoid spring-back error, which is typically 0.5 degrees in a press brake.
For brackets over 400 mm in length, we recommend adding a stress-relief groove on the backside. This prevents the part from bowing after you remove it from the vise. Our standard linear tolerance is ±0.05 mm, but we hold ±0.01 mm on hole positions that dictate alignment. Review our CNC machining tolerances guide to pick the right grade for each feature.
Raw machined aluminum looks industrial. If you want a brushed look, we do a 120-grit belt finish followed by clear anodize. For a matte black aesthetic, we offer Type II anodize in black or grey, which adds 15 µm to the surface. For steel brackets, we offer black oxide, zinc plating (clear or yellow), or powder coating in RAL colors with 80 µm thickness.
We also laser-etch your logo, part number, and a date code on the visible face. The etch depth is 0.02 mm, so it survives anodizing. If you need a polished mirror finish on stainless steel, we can achieve Ra 0.2 µm, but that is only recommended for decorative brackets, not structural ones, because it removes material from the surface.
We pack CNC Machined Furniture Brackets in partitioned corrugated boxes with foam inserts. Each bracket is individually wrapped in VCI paper to prevent corrosion during ocean freight. For high-volume orders, we offer plastic trays with custom-cut slots so your robot arm can pick the parts directly. We also put a barcode label on each box that matches your part number and purchase order.
If you assemble brackets with screws, we can pre-install threaded inserts (M4 to M8) at a cost of $0.03 per insert. We also offer a kitting service where we combine the bracket, screws, and washers into one sealed bag, reducing your assembly time by 15 seconds per unit.
Send us a 2D PDF and a 3D STEP file. Our engineers review the design within 4 hours and flag any features that are hard to machine, like deep slots or 0.5 mm internal corners. We give you a firm quote with a price break at 1, 10, 100, and 1,000 pieces. There is no tooling fee for standard parts under 200 mm. For custom shapes, we charge a one-time programming fee of $50 to $200, which is waived for the first production order.
We start cutting samples within 48 hours of approval. You get 3 free samples for any order over 100 pieces. Production lead time is 10 business days for aluminum and 14 days for steel. We ship via DHL, FedEx, or sea freight from Shenzhen port. FOB price is per unit, and we handle export customs clearance.

No MOQ. We machine a single prototype at the same quality level as a 10,000-piece run, and you pay only for the parts plus a small programming fee for custom designs.
Yes, we use a profilometer to measure your sample's Ra and Rz values, then adjust our sanding and polishing parameters to replicate it within ±0.1 µm.
We use in-process probing on the CNC machine every 20th part, and a final CMM audit on 5% of the batch, plus a visual inspection of 100% for burrs and scratches.
For a standard 6061 aluminum bracket under 150 mm, we can rush 50 pieces in 48 hours at a 20% surcharge, and ship via express air.
