Import Deep Hole Drilling Machine For Small Size — Buy in Bulk from Supplier in China

The Deep Hole Drilling Machine for Small Size, model DH-1816, is designed for precision gun drilling of holes with diameters between 2mm and 38mm, with an optional capacity up to 50mm. It supports a maximum drilling depth of 1600mm and features a worktable size of 1700mm by 1000mm, capable of holding up to 15,000kg. The machine uses an OZ25 spindle taper and belt-driven transmission with a maximum spindle speed of 8000rpm, driven by a 11kW rated / 15kW max motor. Positioning accuracy is specified at 0.025mm and repositioning at 0.015mm, with axial deflection controlled to no more than 0.45mm per 1000mm under standard conditions.

The machine employs a high-pressure coolant system with a 630L reservoir, delivering oil at 70MPa pressure and a flow rate of 67L/min, which is standard for deep hole drilling to ensure chip evacuation and tool life. The cooling pump is rated at 5.5kW with a 7.5kW overload option. Structural rigidity is achieved through a heavy-duty cast iron frame and linear guide systems on all axes, typical for industrial-grade deep hole machines in this class. The machine’s overall dimensions are 5000mm by 4300mm with a height of 2800mm and a total weight of 16 tonnes, reflecting its industrial construction.

This machine is primarily used in aerospace, automotive, and hydraulic component manufacturing where straight, deep, high-tolerance holes are required in hardened steels and alloys. Buyers include precision machining shops, OEM component suppliers, and tooling manufacturers sourcing equipment for internal bore processing. Trade terms are typically FOB Guangzhou or CIF, with payment via 30% advance and 70% before shipment. Packaging is standard in fumigated wooden crates on iron pallets, with full protective film covering all moving parts. Delivery lead time is not stated but begins after advance payment confirmation.

Dongguan Estop Machinery Co., Ltd. is a manufacturer and exporter of CNC machine tools based in Changping Town, Dongguan, Guangdong Province, China. The company was founded by a team of engineers with over 20 years of experience in CNC milling and grinding machine design, primarily operating from the manufacturing hub of Guangdong. The listing confirms no revenue figures, employee count, or export history beyond its stated role as a producer of CNC equipment. Its trust tier is listed as 'harbor', indicating basic platform verification but no third-party audit or certification.

The supplier does not claim ISO certification, international client names, or years in operation beyond the implied experience of its engineering team. It does not list a website, sales offices abroad, or after-sales service centers outside China. Its primary value proposition is cost-effective machinery production leveraging local supply chains. There is no mention of R&D facilities, custom design services, or in-house tooling capabilities beyond standard CNC machining. Buyers should verify operational status and technical support availability directly before placing orders.
