Vibratory Mass Finishing
Ideal for high-volume Traub turnings. Parts are tumbled in specialized acoustic chambers with ceramic or steel media to deburr, burnish, and uniform thousands of components simultaneously.
Micrometric Surface Engineering
Surface Polishing & Finishing
Elevating cam-turned Traub components to exact micro-inch roughness ($R_a$) specifications. We deliver mirror finishes, minimized friction coefficients, and clinically clean surfaces engineered for Tier-1 two-wheeler and four-wheeler mobility systems.
Why Surface Roughness Matters
Eliminating Micro-Friction in Automotive Systems.
Even the most precise cut from a high-speed automatic lathe leaves microscopic peaks and valleys on the metal surface. In high-RPM two-wheeler engine shafts, hydraulic brake guide pins, or EV transmission bushings, these micro-imperfections generate friction, heat, and premature component wear.
At Annectotech LLP, our secondary polishing and micro-finishing division in Faridabad bridges the gap between raw Traub machining and assembly-line perfection. We deploy specialized mechanical and abrasive finishing methodologies to level surface geometry, deburr microscopic edges, and achieve optimal oil-retention cross-hatches without altering your critical dimensional tolerances.
- Extended Component Life: Drastically reduces initial wear and tear during engine break-in cycles.
- Superior Fluid Sealing: Creates flawless seating surfaces for O-rings, gaskets, and hydraulic seals.
- Enhanced Corrosion Resistance: Smooth, polished surfaces leave fewer microscopic crevices for rust initiation.
Our Capabilities
Comprehensive Finishing Processes
We match the specific geometry and volume requirements of your automotive space parts with the ideal industrial finishing technique.
Centerless Superfinishing
Engineered for cylindrical dowel pins, shafts, and axles. Utilizes fine-grit abrasive rolls to achieve ultra-low roughness values ($R_a < 0.1\,\mu\text{m}$) with absolute cylindrical roundness.
Mechanical Mirror Buffing
High-lustre aesthetic and functional polishing for exposed two-wheeler hardware, stainless steel fasteners, and custom brass electrical connectors requiring zero surface oxidation.
Ultrasonic Degreasing
High-frequency cavitation bath cleaning that strips microscopic abrasive slurry, cutting oils, and particulate matter, leaving components clinically clean for immediate assembly or plating.
Quality Verification
Digital Profilometry & SPC Tracking.
In precision automotive supply chains, visual inspection is never enough. You cannot verify a micro-inch roughness tolerance with the naked eye. That is why Annectotech LLP integrates digital metrology directly into our finishing workflow.
Every batch of polished components undergoes statistical sampling using calibrated stylus profilometers and surface roughness testers. We verify that both the arithmetic average roughness ($R_a$) and maximum peak-to-valley height ($R_z$) comply strictly with your CAD drawing notes before the batch is cleared for packaging.
- Roughness Average ($R_a$) Capability: 0.05 µm to 1.6 µm
- Inspection Standard: ISO 4287 / DIN 4768
- Quality Documentation: MTC & Profilometer Reports
Engineering Blueprint
Automotive Surface Roughness Standards
A reference guide mapping our surface polishing capabilities to standard two-wheeler and four-wheeler automotive space part applications.
| Automotive Component Application | Target Roughness ($R_a$) | Primary Polishing Method | Functional Engineering Benefit |
|---|---|---|---|
| Hydraulic Brake Guide Pins | 0.1 µm - 0.2 µm | Centerless Superfinishing | Prevents caliper binding; ensures smooth lateral brake pad movement. |
| Engine Valve Stems & Tappets | 0.08 µm - 0.15 µm | Lapping & Micro-Buffing | Minimizes guide bushing wear under high-temperature, high-RPM friction. |
| Transmission Gear Spacers | 0.4 µm - 0.8 µm | Vibratory Mass Finishing | Removes Traub parting burrs; creates flat seating for axial thrust loads. |
| Two-Wheeler Axles & Pivot Pins | 0.2 µm - 0.4 µm | Cylindrical Grinding & Buffing | Protects wheel bearing seals; prevents ingress of road dust and moisture. |
| Threaded Brass Electrical Inserts | 0.8 µm - 1.6 µm | Abrasive Barrel Tumbling | Cleans thread crests; ensures burr-free molding into EV plastic housings. |
Ecological Integrity
ZED-Compliant Green Polishing
In alignment with our national MSME ZED (Zero Defect, Zero Effect) mandate, our surface finishing operations in Faridabad prove that high-lustre industrial polishing can be completely environmentally responsible.
Slurry Filtration & Reuse
All abrasive compounds and liquid burnishing slurries used in our vibratory machines pass through multi-stage centrifugal filtration, allowing us to safely recycle water and capturing 99.8% of metal particulate.
Non-Toxic Compounds
We strictly prohibit the use of hazardous cyanides or aggressive acid-dumping brightening agents. Our polishing media relies on biodegradable, organic burnishing soaps that protect worker health and local ecosystems.
Zero Untreated Discharge
Operating under full Haryana State Pollution Control Board (HSPCB) guidelines, our facility generates zero untreated effluent, ensuring our manufacturing footprint leaves zero negative impact on local waterways.
