Auto Tapping (M3–M32) in Mumbai: overview
High-volume internal threading from M3 to M32. Dedicated auto tapping machines cut consistent internal threads at production speed, with thread gauges used for go/no-go checks.
Every order is programmed in VISI or Delcam CAM, machined on Auto tapping machines, M3 to M32 capacity, and inspected in our Mitutoyo quality lab before it is packed and shipped.
Auto Tapping (M3–M32) capability
We run auto tapping (m3–m32) on dedicated machines, so prototypes, pilot lots and production runs all follow the same documented process. Common parts include flanges, fittings, custom fasteners 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 Threads to 6H class, checked with plug gauges. 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.
Surface finish is typically Ra 1.6–3.2 µm as machined, with Ra 0.8 µm achievable on turned sealing and bearing surfaces. Plastics are finished with sharp tools to avoid smearing and burrs.
Plating, anodising, passivation and heat treatment are arranged through qualified partners and re-inspected in-house before packing.
Quality inspection process
Quality is built into every step under our ISO 9001:2015 management system. Raw material is checked against its mill certificate, the first article is fully inspected against the drawing, and in-process checks run at defined intervals.
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
