TMC-740L CNC Drilling and Tapping Machining Center

The TMC-740L CNC Drilling and Tapping Machining Center represents the ideal balance between high-speed drilling, tapping, and light-to-medium milling operations. Built on a reinforced, wide-span casting base, this model is engineered for workshops that handle larger, multi-cavity aluminum castings and steel plate components. Our development history spans over thirty years, transitioning from producing high-durability bearings and structural optical machines to establishing our current complete CNC machining brand. This deep manufacturing heritage allows us to control the entire production cycle in-house, utilizing Taiwanese precision guideway grinders to finish-machine every critical mating surface. The result is a highly stable machine frame that virtually eliminates structural harmonics during rapid axes acceleration.

To meet global import standards, the TMC-740L CNC Drilling and Tapping Machining Center is manufactured in strict compliance with ISO9001 and CE certifications, utilizing premium electronic and mechanical components. Every machine we build is delivered in export-grade, heavy-duty sea packaging designed to protect against moisture and corrosion during long ocean transits.

Application Areas

Automotive Structure Parts

Precision machining of battery trays, steering knuckles, and engine mounting brackets.

Mold & Die Base

Fast roughing and finish drilling of mold plates, ejector pin holes, and locating guide holes.

Medical Equipment

High-efficiency milling and tapping of aluminum enclosures, surgical tool brackets, and medical monitor stands.

Factory Strength & Infrastructure

We operate a complete, integrated production facility. Our facility is equipped with heavy industrial casting finishing zones, precision optical machine alignment benches, and advanced measurement equipment. By keeping all key manufacturing steps - from rough casting processing to final paint application - under one roof, we eliminate intermediate markups and pass the savings and quality assurance directly to our overseas clients.

Export Packaging & Shipping

We use professional ocean-freight packaging to ensure your machine arrives in perfect condition. The machine tool is thoroughly coated with rust-inhibiting oils, vacuum-sealed in heavy-duty moisture-proof plastic wrap, and bolted securely inside a fumigated solid wooden crate. We cooperate with leading shipping lines to handle customs documentation and ensure safe, on-time delivery to your port of choice.

Certification & Awards

Our quality and innovation are recognized at the highest levels. Our plant is ISO9001 certified, and our parent enterprise is recognized as a National-level "Little Giant" (indicating specialization and high-tech manufacturing quality). We hold provincial awards for technical achievement and have a dedicated provincial-level high-tech R&D center focused on continuous machining improvements.
