Cylindrical Grinding & Surface Grinding Services in Gurgaon | Job Work for Turned and Milled Parts
Grinding is the final process when CNC turning or milling alone cannot achieve the required surface finish or dimensional accuracy. We provide cylindrical grinding and surface grinding job work in Gurgaon for shafts, bores, flat surfaces, and components where Ra and close-tolerance finishing matter.
When is grinding the right process?
Most machined parts end on a CNC lathe or milling centre. But when the drawing calls for a surface finish below Ra 0.8µm, a bore or shaft diameter held to IT5–IT6 class, or a flat face that must be within a few microns, grinding is the correct finishing operation — not a finer turning pass.
Cylindrical grinding is used for external diameters and tapers on shafts, spindles, pins, rollers, and hardened components where the turned surface finish is not tight enough for the mating assembly. Surface grinding is used for flat faces, parallels, die-set plates, gauge blocks, and any component where datum flatness and surface quality are critical to fit or function.
Both processes work alongside our CNC turning and precision machining capability. A typical flow is: rough turning → semi-finish turning → heat treatment → cylindrical grinding to final diameter. For die and press-tool components, the flow is usually: milling → heat treatment → surface grinding to final height and flatness.
Our workshop in Sector 18, Sarhol, Gurgaon serves buyers across Gurugram, IMT Manesar, Faridabad, and Delhi NCR. For automotive Tier-1 and Tier-2 suppliers where shaft and bore grinding is a standard finishing step, we offer grinding as a standalone job or as part of a broader machining package.
Cylindrical grinding vs surface grinding — what we support
Cylindrical Grinding
External cylindrical grinding for shafts, spindles, rollers, pins, and precision turned components. Used to achieve close-tolerance diameters and superior surface finish after heat treatment or where turning alone is not sufficient.
- Shafts, stepped shafts, and motor spindles
- Hardened pins, rollers, and precision mandrels
- Hydraulic piston rods and valve stems
- Automotive camshafts, crankshaft journals, and guide pins
- Tool shanks, arbors, and grinding wheel adapters
- Any turned part needing Ra ≤ 0.8µm or IT5/IT6 diameter tolerance
Surface Grinding
Precision flat surface grinding for die plates, tool room components, gauge blocks, parallels, and any part where the milled surface needs tighter flatness, accurate height, and improved surface quality.
- Press tool die plates, punch holder plates, and backing plates
- Fixture bodies and tooling base plates needing flat datums
- Gauge blocks, parallels, and setting masters
- Machine guide ways and precision flat slides
- Hardened blocks requiring final size after heat treatment
- Any milled part needing flatness under 0.01mm or Ra ≤ 0.8µm

What makes grinding jobs work at our workshop
Pre-grind Inspection
Stock allowance and pre-grind dimensions are checked before the part goes to the grinding machine to avoid wastage of hardened components.
Post-grind Measurement
Final diameter and surface finish are verified after grinding. Shafts are checked with a micrometer and surface finish with a profilometer reference.
Material Suitability
Hardened and tempered components grind more predictably. We review heat treatment hardness before scheduling to confirm the process will achieve the specified tolerance.
Part of a Larger Flow
Grinding is often the last step. We can manage the full sequence — rough turning, heat treatment coordination, and finish grinding — from one workshop.
Grinding Services FAQ
What is cylindrical grinding and when is it needed?
Cylindrical grinding is a precision finishing process for external diameters on shafts, rollers, and pins. It is needed when the part requires tighter dimensional tolerance than CNC turning can achieve (typically IT5/IT6 class), a surface finish below Ra 0.8µm, or when the component has been hardened and turned diameters need finishing to final size.
What is surface grinding used for in industrial machining?
Surface grinding removes material from flat faces to achieve accurate height, tight flatness, and fine surface finish. Common applications are die plates, fixture base plates, gauge blocks, parallels, hardened blocks after heat treatment, and any flat component where the milled surface is not flat or fine enough.
What surface finish and tolerances can you hold with grinding in Gurgaon?
Standard grinding at our workshop achieves Ra 0.4–0.8µm surface finish. Cylindrical grinding holds diameters to ±0.005–0.01mm (IT5/IT6 equivalent). Surface grinding holds height to ±0.005–0.01mm and flatness to 0.005–0.01mm over 100mm.
Can you grind hardened steel components?
Yes. Grinding is specifically suited to hardened components — typically 55–65 HRC tool steel, alloy steel, and case-hardened parts — where turning is no longer effective. Heat treatment is usually done before the grinding step.
Do you provide cylindrical grinding job work near IMT Manesar?
Yes. Our workshop in Sector 18, Sarhol is 10–15 km from IMT Manesar. We support automotive and industrial buyers in the Manesar belt with both standalone grinding jobs and combined machining packages.
What is the difference between cylindrical grinding and surface grinding?
Cylindrical grinding operates on rotating parts — it grinds external diameters (shafts, pins, rollers). Surface grinding operates on stationary flat parts — it grinds flat faces (plates, die sets, parallels). Both achieve similar surface finish and tolerance levels but apply to different component geometries.
Can you handle the turning, heat treatment coordination, and grinding together?
Yes. For components that need the full sequence — rough turning, semi-finish, heat treatment, and grinding to final size — we manage the machining stages from our workshop and coordinate heat treatment with trusted local processors.
