Precision Drilling & Boring in Pune: overview

Accurately positioned holes and bored diameters. Holes are spot-drilled, drilled and finish-bored or reamed on the VMC and CNC lathes for true position and size.

Every order is programmed in VISI or Delcam CAM, machined on Ace Micromatics VMC and CNC lathes, and inspected in our Mitutoyo quality lab before it is packed and shipped.

Precision Drilling & Boring capability

Our precision drilling & boring cell handles single prototypes through repeat batches of tens of thousands. Typical work includes flanges, bushings and valve components.

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 Bores to H7; hole position ±0.02 mm. 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.
