Import Deep Hole Drilling Machine For Mold Processing — Buy in Bulk from Supplier in China

The deep hole drilling machine for mold processing from Dongguan Estop Machinery Co., Ltd. is designed for precision bore operations in hardened tool steels and mold components, with a standard drilling depth-to-diameter ratio of up to 100:1. It features a CNC-controlled feed system with positional accuracy of ±0.01 mm and spindle speed range of 50 to 3000 rpm, calibrated for stable chip evacuation in deep cavities. The machine's hydraulic clamping system holds workpieces up to 1200 mm in diameter and 800 mm in height, suitable for injection mold inserts and die-casting cores.

The machine uses a BTA-type internal chip removal system, typical for deep hole drilling in mold applications, and is compatible with standard carbide-tipped gun drills in diameters from 3 mm to 25 mm. The guide bushings are hardened and ground to HRC 60 - 62, ensuring minimal runout over extended cycles. The coolant delivery system operates at 5 - 15 bar pressure, with filtration down to 10 microns, which is standard for maintaining tool life in high-precision mold machining. The machine bed is cast iron with vibration-dampening ribs, a common design in industrial-grade deep hole equipment.

This machine is primarily purchased by mold makers in Southeast Asia and Eastern Europe who require consistent bore geometry in hardened steel without secondary honing. Buyers typically order with fixed or adjustable tailstock options, and the machine is shipped with basic tooling kits. Standard delivery is FOB Shenzhen, with lead times of 6 to 8 weeks after deposit. No certification documents are listed; buyers should request ISO 9001 process records and final inspection reports before shipment.

Dongguan Estop Machinery Co., Ltd. is a manufacturer based in Changping Town, Dongguan, Guangdong, with a physical address registered in industrial park infrastructure. The company has no public website, and its response rate and average reply time are not tracked in the system, indicating limited digital engagement. It is classified as a harbor-tier supplier, suggesting it has passed basic platform verification for business registration and physical address but has no third-party certification badges visible.

The company does not publish company history, workforce size, export volume, or client names. Its listing is supported only by the product description and address verification. There is no mention of R&D teams, in-house tooling capabilities, or after-sales service infrastructure. Buyers should treat this as a direct manufacturer without verified quality systems and request operational demonstrations or third-party inspection reports before committing to order.
