This precision gear type gripper bracket is a full 5-axis CNC milled custom component engineered for high-repeatability positioning, automated tooling connection, and heavy-duty fixture systems. Every single feature — including the mating gear profile, through-bore mounting holes, and zero-backlash interface — is machined from solid stock, no sintering, no 3D printing, no secondary casting filler, to deliver consistent performance even under 24/7 industrial cycle loads.
Base Material | 6061-T6 Aluminum Alloy (Marine Grade) |
|---|---|
Hardness | 90 HB (T6 tempered, no soft spots) |
Tensile Strength | ≥ 310 MPa |
Surface Finish | Ra 0.8 – 1.6 μm, bead blasted + clear anodized optional |
Corrosion Resistance | Salt spray test ≥ 48 hours (anodized finish) |
Machining Stability | Zero deformation after post-machining stress relief |
📌 Highlighted Note: We choose 6061-T6 as the baseline material for this part because it balances high rigidity, low inertia, and outstanding chip-clearing performance during milling — critical for a gripper bracket that needs to move fast, hold position tight, and avoid jamming on gear teeth. No recycled aluminum billet is ever used on production orders.
All dimensions are nominal tolerances at ±0.02 mm, per ISO 2768-mk fine machining standard. You may request custom sizes for your project.
Parameter | Value (Standard Offline Version) | Note |
|---|---|---|
Overall Outer Diameter | 68 mm | ✅ Gear pitch circle diameter matched to 12-tooth standard power chuck interface |
Overall Thickness | 22 mm | ✅ Including integrated top gear profile + bottom flange mounting base, no separate assembled parts |
Center Bore Diameter | 16 mm H7 | ✅ Precision reamed for shaft press-fit or slip-fit alignment |
Mounting Hole PCD | 52 mm, 4 x M6 through holes | ✅ Symmetrically distributed for even clamping force, zero wobble under load |
Gear Profile Module | Module 2, 12 teeth | ✅ Full CNC hobbed on milling center, no wire-cut or EDM rough edges |
Total Weight | 178 g (6061-T6 version) | Low moving mass for high-cycle automation lines |
Max Static Clamping Load | ≥ 1200 N | Tested on dedicated fixture bench before shipping |
We do not produce this part on standard 3-axis machines. Every unit runs on 5-axis simultaneous CNC mills to guarantee the gear face, flange reference plane, and all mounting holes share a single zero-origin — no secondary re-clamping error.
Zero-backlash gear mating surface
The 12-tooth gear profile is milled in one continuous pass, then hand-polished only on the engagement flank, to eliminate play when coupling with your power chuck or actuator. You will not feel any clearance when rotating the bracket into locked position.
Monolithic one-piece body
No welded joints, no glued inserts, no assembled stacked plates. The entire bracket is machined from a single solid billet, so there is zero risk of part separation even under sudden impact load.
Reference back-ground flatness ≤ 0.01 mm over full flange
The bottom connection flange face gets a final ultra-fine fly-cut pass after roughing and stress relief. When you bolt this bracket to your machine table, it sits perfectly flat without needing shims.
Full deburr + edge break on every corner
All sharp edges, hole entrances, and gear tooth tips are manually broken to R0.2 – R0.3 mm. No micro-chips will fall off into your automation line during operation, and operators will not cut their hands during assembly.
We do not limit this bracket to a single material. We can machine the exact same geometry from your required stock material, with the same full precision process:
Material Category | Available Options | Typical Use Case |
|---|---|---|
Aluminum Series | 6061-T6, 7075-T6, 5083, 6082 | Standard automation, low inertia, corrosion resistant |
Stainless Steel | 303, 304, 316L, 17-4 PH H900 | Food & pharmaceutical machinery, high hygiene, high strength |
Carbon Steel | 1045, S45C, C45, 4140 | Heavy load, high torque, weldable to existing frames |
Engineering Plastic | POM (Delrin), PEEK, PA66+GF30 | Non-conductive, low weight, non-marring for soft workpiece gripping |
Copper / Brass | C3604, C11000 | Electrical contact, heat dissipation, special anti-spark requirements |
📌 Highlighted Note: All non-aluminum material versions will get extra post-machining stress relief, and we will adjust feeds/speeds specifically for the material you select to avoid tool chatter, overheating, or tooth profile deformation.
Q1: Can I get this gear type gripper bracket modified to my own custom dimensions or gear profile?
A1: Yes 100%. We can adjust the outer diameter, gear module, bore size, hole pattern, or add custom keyways/set screw holes directly from your 2D/3D CAD file. No extra tooling charge for most custom changes on CNC milled parts.
Q2: What tolerances can you guarantee on the gear engagement face?
A2: We guarantee total tooth profile error ≤ 0.015 mm, total runout of the gear face against the bottom flange ≤ 0.01 mm. For ultra-precision robotic applications, we can push runout down to ≤ 0.005 mm on request.
Q3: Do you provide surface treatment options after machining?
A4: Yes. We support clear/color anodizing (aluminum), passivation (stainless steel), black oxide / manganese phosphate coating (carbon steel), bead blasting, polishing, and PTFE dry lubricant coating, all done in-house or via our certified long-term surface treatment partners.
Q4: What if the part does not fit my existing assembly after I receive it?
A5: We run a full CMM (coordinate measuring machine) inspection on every production batch before shipping, and we provide free 2D dimensional inspection report on request. If any dimension fails to meet your agreed drawing tolerance, we will remake or refund the unit for free at our cost.
