Tight Tolerance Seals & Rings in Pune: overview
Critical features held to ±0.005–0.01 mm. Critical features are finished in a controlled final pass, measured with Mitutoyo micrometers after temperature stabilisation, and recorded on the inspection report.
These parts are with critical features held to ±0.005–0.01 mm. Every order is programmed in VISI or Delcam CAM, machined on CNC turning centres and VMC, and inspected in our Mitutoyo quality lab before dispatch.
Tight Tolerance Machining capability
Our tight tolerance machining cell handles single prototypes through repeat batches of tens of thousands. Typical work includes seals & rings.
Machined seals, back-up rings, wear rings, piston rings and gaskets. Typical features we machine: Thin walls, scarf cuts, precise groove fits, smooth sealing faces.
- CNC turning centres (LMW, Jyoti, Ace Micromatics): Shafts, bushings, fittings, turned plastic parts
- Vertical machining centre (VMC) (Ace Micromatics, FANUC control): 3-axis milling, bed 800 × 500 × 400 mm
- Auto tapping machines (M3 to M32 capacity): High-volume internal threading
- Conventional lathe (Uma Enterprises): Turning up to Ø400 × 1200 mm
- Band saw (Rajlaxmi): Bar stock cutting and blank preparation
Tolerances & surface finish
Standard capability for this work is ±0.005 mm on selected turned diameters by agreement; ±0.01 mm typical. Bores can be held to H7 and bearing seats to h6/g6 fits. Where your drawing calls for tighter limits, we agree the critical characteristics up front and record them on the inspection report.
As-machined finishes of Ra 1.6–3.2 µm suit most functional surfaces. For seals, bearing journals and sliding fits we run a fine finishing pass to reach Ra 0.8 µm.
Plating, anodising, passivation and heat treatment are arranged through qualified partners and re-inspected in-house before packing.
Quality inspection process
Our ISO 9001:2015 system covers incoming material, first-article inspection, in-process checks and final inspection. Records are kept for every batch so any part can be traced back to its material heat.
For seals & rings, inspection covers: ID/OD and cross-section with calipers and micrometers, visual face inspection.
- Mitutoyo digital vernier calipers
- Mitutoyo height gauge
- Granite surface plate
- Mitutoyo outside micrometers
- Inside calipers and bore gauges
- Dial test indicators
