Tight Tolerance Flanges in Panvel: overview
Vertical machining centre work for prismatic parts up to 800 × 500 × 400 mm. Parts are clamped on the VMC table and machined in one or more set-ups: face milling, pocketing, drilling, boring, tapping and contouring.
These parts are with critical features held to ±0.005–0.01 mm. Every order is programmed in VISI or Delcam CAM, machined on Ace Micromatics VMC, FANUC control, bed 800 × 500 × 400 mm, and inspected in our Mitutoyo quality lab before dispatch.
VMC Machining capability
Our vmc machining cell handles single prototypes through repeat batches of tens of thousands. Typical work includes flanges.
Custom and standard-pattern flanges, adaptor plates and mounting flanges. Typical features we machine: PCD-drilled holes, spigots, O-ring grooves, tapped holes, raised 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 ±0.02 mm general; positional accuracy of holes ±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.
For flanges, inspection covers: PCD and hole position on surface plate, bore with inside calipers, flatness with dial indicator.
- Mitutoyo digital vernier calipers
- Mitutoyo height gauge
- Granite surface plate
- Mitutoyo outside micrometers
- Inside calipers and bore gauges
- Dial test indicators
