Direct answer
What you get when you order Nylon Machining
Wear-resistant nylon bushings, rollers and wear pads. The work is quoted from your drawing and 3D model, made to the revision you release, and delivered with a dimensional inspection report for the batch. Standard capability for this process is ±0.05 mm typical. Polymer stock is cut with sharp, high-rake tooling and left to stabilise at room temperature before it is measured, because machining heat moves a plastic section much further than a steel one. There is no fixed minimum order: a single prototype and a 10,000-piece release follow the same documented route through programming, first-article inspection and export packing from our ISO 9001:2015 certified shop in Pune.

Nylon Machining: overview
Wear-resistant nylon bushings, rollers and wear pads. Cast and extruded nylon is turned and milled, allowing for moisture absorption in the final dimensions agreed with you.
Every order is programmed in VISI or Delcam CAM, machined on CNC turning centres and VMC, and inspected in our Mitutoyo quality lab before it is packed and shipped.
Nylon Machining capability
Our nylon machining cell handles single prototypes through repeat batches of tens of thousands. Typical work includes bushings, insulators and seals & rings.
Before quoting, our engineers review your STEP, IGES or PDF drawing for machinability and suggest changes that reduce cost without affecting function.
- 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 ±0.05 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.
Every shipment includes a dimensional inspection report, with material test certificates (EN 10204 3.1) on request.
- Mitutoyo digital vernier calipers
- Mitutoyo height gauge
- Granite surface plate
- Mitutoyo outside micrometers
- Inside calipers and bore gauges
- Dial test indicators
Envelope, tolerance and quantity
Three things decide whether a part belongs here: its size, the tightest feature on it and the quantity you need. The figures below are the limits of the machines and instruments actually in the Pune shop.
Size and set-up
Will the part fit our machines
- Turned diameter
- Up to Ø400 mm on the conventional lathe; smaller bar and billet work on the CNC turning centres
- Turned length
- Up to 1200 mm between centres
- Milled envelope
- 800 × 500 × 400 mm on the 3-axis VMC
- Threading
- M3 to M32 auto tapped; metric, BSP, NPT and UNC/UNF single-point or thread-milled
- Blanks
- Rod, tube or plate cut to length on the band saw and deburred, with the stock lot identified against the works order
Tolerance, fits and finish
What is held, and how it is checked
- Standard for this work
- ±0.05 mm typical
- Unmarked dimensions
- ISO 2768-m unless your drawing states another class
- Fits
- Agreed as a diametral clearance in millimetres rather than an ISO 286 class, because the polymer moves with temperature and load
- Surface finish
- Ra 1.6–3.2 µm as machined; sealing faces fine turned with a sharp, high-rake tool
- Verified with
- Mitutoyo micrometers, vernier calipers and height gauge, inside calipers, bore gauges and dial test indicators on a granite surface plate
- Measured when
- After the part has stabilised at room temperature, so the reading on the report is the one you will receive

How a Nylon Machining order runs
The same five stages for a one-off and for a scheduled release. Nothing is cut before the quote and the drawing revision are agreed in writing.
- 01
Drawing in, NDA first if you want one
Send the PDF with a STEP or IGES model, the grade, the batch quantity and the destination. We sign an NDA before the files move if your part is confidential.
- 02
DFM review and quotation
An engineer rebuilds the set-ups in VISI or Delcam, queries anything undimensioned or unmeasurable, and flags features that cost more than they return. Price and lead time come back within 24 hours.
- 03
Stock and blank preparation
Rod, tube or plate in Nylon is bought to grade and cut to length on the band saw, with each blank identified against the works order so the batch stays traceable.
- 04
Programme, first-off and sign-off
The verified toolpath is loaded on the equipment this process uses — CNC turning centres and VMC — and the first part off is measured against every drawing dimension. On a new part, that report goes to you for approval before the batch continues.
- 05
Production, final inspection and packing
In-process checks run at set intervals against the agreed critical characteristics. Any partner plating, anodising, passivation or heat treatment is re-inspected here on return. Parts then go into VCI anti-rust film and ISPM-15 heat-treated crates with the full document set.
Industries we serve
This work is used across automotive, hydraulics, pumps & valves and electronics & electrical. Automotive customers, for example, need repeatable high-volume parts at a competitive piece price with consistent quality.
Our core customers are corporate OEMs in automotive, hydraulics, pumps & valves and general engineering, plus multinational companies that need PTFE, Nylon, Delrin and PEEK parts machined to drawing.

Drawing notes that decide the price
Most of the gap between two quotes for the same part comes from the notes around the geometry rather than the geometry itself. These are the ones that move our price the furthest.
Put this on the drawing
- Say at order placement if you need the stock supplier's material certificate, because it is pulled with the stock rather than reconstructed afterwards.
- List every partner operation you need — plating, anodising, passivation, heat treatment — so its transit sits inside the quoted delivery date.
- Send a STEP or IGES model alongside the PDF. Dimensioned views are enough for prismatic parts and slow for contoured ones.
- Say whether a dimension applies as-machined or after conditioning, and at what temperature it is to be verified.
- Mark the three or four features that actually matter and leave the rest at ISO 2768-m. We price the recorded measurements as much as the material.
What quietly inflates the price
- A revision issued after the stock is cut. Stock is bought and sawn to the lengths on the drawing we quoted.
- Internal pocket corners below R1.5, or pockets deeper than about five times their width. Both force a long, slow cutter and extra finishing passes.
- A metal tolerance on a thin polymer section. Nylon expands, relaxes and takes up clamping load far more than steel does, so ±0.01 mm on a thin wall cannot be guaranteed once the part leaves the surface plate.
- A blanket ±0.01 mm in the title block. Every feature then earns a finishing pass and a recorded measurement, and the quote has to carry both.
- Ra 0.4 µm on faces that nothing touches. A finishing pass for appearance costs the same as one for function.
How to order
Getting a quote for nylon Machining is simple:
- Send your drawing (PDF) and 3D model (STEP or IGES) with material, quantity and destination.
- Our engineers review it and send a quote with lead time within 24 hours.
- Approve samples or a first-article report for new parts.
- We machine, inspect, pack and ship with full export documents.
What is in scope, and what is not
Where Nylon Machining starts and stops here, stated plainly so you can check it against your approved-vendor requirements before sending a drawing.
Programmed before anything is cut
Your model is built into set-ups in VISI or Delcam and the toolpath is simulated, so the first part off the machine is a check rather than an experiment.
Measured in-house, with the limits stated
Mitutoyo micrometers, vernier calipers and height gauge, inside calipers, bore gauges and dial test indicators, used on a granite surface plate. There is no CMM, optical comparator or hardness tester here; a feature needing one is sent out and priced that way.
The approvals we hold, and those we do not
ISO 9001:2015, with inspection records kept per batch. We do not hold AS9100 or ISO 13485 and do not take flight-critical or implanted-device work. Industrial, hydraulic, pump, valve and general engineering parts are the normal scope.
Handled as polymers, not as soft metal
Each polymer gets its own tool geometry, speeds and light finishing passes, with stress relief or annealing arranged where a tight tolerance needs it, and measurement held back until the part is at room temperature.
Traceability you can audit
The stock lot recorded against the works order, the supplier's material certificate where the grade is supplied with one, a dimensional inspection report with every shipment, and an NDA signed before drawings change hands.
Packed and documented for export
VCI anti-rust film and ISPM-15 heat-treated crates, with commercial invoice, packing list, certificate of origin and inspection report. Parts leave Pune for 45+ countries EXW, FOB Nhava Sheva (JNPT) or Mumbai, or CIF.
