PROBITERS ROI: 4.6 Months PAYBACK

❌ Competitor Machine Pitfalls

Single-ended center hole drilling created concentricity misalignment between opposing shaft ends, causing grinding machine rejections and wheel wear downstream.

❌ Impact: High Scrap Rates & Unplanned Supplier Delays

Probiters Engineering Advantage

Probiters Dual Pneumatic Self-Centering Vise System with synchronized twin opposing gundrilling heads, precision linear guides, and coolant filtration.

Support Commitment:
Same-Day Spindle Service & Alignment Re-Certification

✓ Verified Financial Outcomes & ROI

Payback Period 4.6 Months

Annual Savings ₹13.6 Lakhs / yr

CENTER HOLE ALIGNMENT ERROR 0.4mm Misalignment Down to 0.025mm Zero Downstream Grinding Rejections

"Synchronized twin-head drilling solved our camshaft concentricity issue instantly. Downstream grinding scrap dropped to zero overnight."

Design intent

Dedicated centre-hole gundrilling arrangement for long components and accurate axial drilling.

A centre-hole drilling machine configured for axial drilling from the component centreline. The layout prioritises concentric workholding, stable support and controlled drill feed for long components.

Engineering problem: Centre holes often become reference features for subsequent machining. Poor alignment or inconsistent depth can propagate error into later operations.
