CD‑600 Separate Precision Feeding Saw boosts heat‑sink production for an Indian thermal‑components plant

Located in Pune, Maharashtra, the plant specialises in extruded aluminium heat sinks for new‑energy inverters, 5G base stations and power‑electronic assemblies. Driven by rapid expansion across India’s renewable‑energy and communications sectors, the site faced steeply rising order volumes for thin‑fin heat‑sink profiles.

Existing conventional cutting equipment could no longer keep pace with growing production demands. Poor cut quality, frequent fin chipping, high manual rework and elevated consumable costs created consistent bottlenecks in their blanking workflow. The management team set out to source a high‑performance automatic sawing system capable of meeting strict series‑production specifications.

Key operational requirements

When evaluating new sawing machinery, the production team defined clear operational and quality targets:

• Achieve scratch‑free, burr‑free end faces on thin‑wall heat‑sink profiles, minimising labour‑intensive manual deburring and reducing reliance on high‑turnover workshop staff.
• Sustain ±0.1 mm cutting accuracy across long‑run mass production to prevent batch rejects caused by dimensional deviation and fin damage.
• Lower overall operating expenditure through extended saw‑blade service life, reduced failure rates and straightforward maintenance, considering high local consumable prices and long spare‑part lead times in India.
• Enable seamless integration with their upstream aluminium extrusion line, supporting recyclable automatic feeding and mixed‑length cutting for flexible multi‑part production.
• Deliver intuitive CNC operation with complete English documentation, alongside accessible local after‑sales support to cope with frequent operator rotation.

Why Chuda Machinery CD‑600 was selected

After reviewing available sawing solutions on the market, the plant opted for the Chuda CD‑600 Separate Precision Feeding Saw. Its patented post‑cut blade‑workpiece separation mechanism directly addresses the persistent issue of profile‑end scratching, a common pain point with standard cut‑off saws. The heavy‑duty stress‑relieved machine bed guarantees stable ±0.1 mm batch cutting performance with spindle accuracy of 0.005 mm, fully matching tight dimensional requirements for power‑electronics heat‑sink components.

The integrated micro‑lubrication atomising cooling unit extends saw‑blade service life and brings down recurring consumable spend, which was a major priority for the Indian manufacturer. Local agent partnership ensures fast spare‑part availability and on‑site service response. Full‑language‑English HMI, simple programming and complete documentation lower operator skill thresholds for high‑turnover workshop environments.

Implementation on‑site

The CD‑600 unit was installed and commissioned at the Pune‑based facility. The unique separation motion pulls the saw blade away from the workpiece upon cut completion, eliminating frictional scratching on delicate heat‑sink fins and drastically cutting post‑cut finishing work.

Multiple stress‑relief annealing processes applied to the welded machine bed resist thermal deformation under continuous 16‑hour‑per‑day operation within India’s high‑temperature factory conditions. The micro‑lubrication system optimises blade cooling while reducing oil consumption. Connected to the existing extrusion production line, the saw handles automatic feeding from 10 mm up to 1100 mm length, supporting recyclable feeding cycles for flexible mixed‑specification runs.

Chuda’s remote technical training together with local‑agent on‑site guidance helped plant engineers master machine operation, adjustment and routine maintenance, offsetting risks created by frequent personnel changes.

Measurable operational improvements

Since putting the CD‑600 into full‑time production, the site has recorded tangible manufacturing gains:

• Defect rates from scratched and burred heat‑sink end faces dropped from 12.7 % down to 1.8 %. Manual deburring workload has been reduced by 82 %.
• Batch cutting tolerance remains steadily held within ±0.1 mm; spindle run‑out holds at 0.005 mm over extended production shifts, lifting pass rates for high‑end new‑energy heat‑sink orders.
• Saw‑blade service life increased by 30 %, bringing monthly consumable procurement costs 26 % lower.
• Daily output of heat‑sink blanks rose from 2 800 pieces to 4 200 pieces, giving capacity to fulfil expanding customer orders.
• Unplanned equipment downtime has been significantly minimised under two‑shift daily production.

“Before deploying the Chuda CD‑600, we struggled to balance heat‑sink cutting quality and production cost. This machine fully delivers scratch‑free surfaces, consistent high precision and lower consumable outlay. Its automated workflow fits our high staff‑turnover workshop environment perfectly, and local‑agent after‑sales support is prompt. It gives us solid ground to scale‑up our new‑energy and 5G heat‑sink projects.”

— Mr. Arjun Deshpande, Production Manager

Transferable application value

The CD‑600 cutting concept offers proven reference for heat‑sink processors across South Asia, Southeast Asia, the Middle East and comparable manufacturing regions. It is well‑suited to facilities producing thin‑fin aluminium heat sinks for new‑energy, 5G and power‑electronics, where manufacturers aim to stabilise cutting precision, reduce manual post‑processing work, control consumable expenditure and operate equipment within high‑labour‑turnover factory set‑ups.
