Products Description
TJ-15L CNC Linear Milling Machine is the flagship product of our Guangdong machine two-line and one-hard series. It is designed to help solve the problem of high-precision heavy cutting of large and complex parts. As a CNC Linear Milling Machine, it has an X-axis travel of 1500mm and a Y-axis travel of 800mm, which can easily accommodate large aerospace structural parts, heavy machinery boxes and oversized molds. The innovative combination of X/Y-axis linear guides and Z-axis box rails not only provides the high efficiency of a three-linear rail machine tool, but also ensures excellent rigidity required for heavy cutting. Adhering to Guangdong's concept of "precision manufacturing", this machine tool perfectly integrates ultra-high precision, efficient integration and excellent rigidity.
Core features and technical advantages
Our machine tool adopts a two-wire and one-hard structure: the X-axis and Y-axis reach 1500mm and 800mm respectively, and can move quickly up to 18 meters per minute, with fast response and accurate positioning; the Z-axis is a 700mm hard rail, which has particularly strong rigidity and vibration resistance, and is specially designed to handle heavy cutting of difficult-to-machine materials. The distance from the spindle center to the guide rail surface is between 130 and 800mm, and the distance from the end surface to the workbench has also been optimized, ensuring good accessibility during processing. In this way, various materials from aluminum alloy to high-strength steel can be processed efficiently on this machine, giving you a true multi-purpose machine. Box-shaped base and large-span A-shaped column ensure good accuracy retention. The extra-wide base and large V-shaped column not only have a large stroke, but also have high rigidity and stability. The cutting ability is also very hardcore. We provide you with a standard 15 kilowatt spindle with a speed of 8,000 to 10,000 rpm. You can also choose BT50 or BT40, which can solve whether it is aluminum alloy or heavy-duty molds. The feed motors for the X, Y, and Z axes are all 4.5 kilowatts, with full thrust. The whole machine weighs about 10 tons and has remarkable stability in the processing process.
Application scenarios – TJ-15L's areas of expertise
TJ-15L is widely used in many processing fields. First of all, let's look at mold processing. The typical sizes of the cavities and inserts of automobile panel molds, home appliance injection molds, and die-casting molds are 800 to 1500 mm. We use imported heavy-duty roller linear rails for the X/Y axis, and a hard rail structure for the Z axis. The rigidity is sufficient during heavy cutting, and the matching accuracy and service life of the mold are significantly improved.
Turning to auto parts, parts such as subframes, wheel hubs, differential cases, and engine brackets are batch processed. The workbench can bear a load of 1.6 tons, and multiple processes of milling, drilling, boring, and tapping can be completed in one clamping.

Looking at general mechanical parts, complex parts such as valve bodies, pump bodies, boxes, plates, and disks are very flexible to produce small and medium-sized batch processing parts of various types. They are used in fields such as precision parts, hydraulic components, and engineering machinery accessories.
And for mass production of thin-walled parts such as 3C and home appliance parts, home appliance casings, new energy battery trays, 5G communication cavities, etc., the surface quality and production efficiency processed by this TJ-15L CNC linear milling machine meet the requirements of the 3C and home appliance industries.
Quality Assurance and Manufacturing Standards
Before each TJ-15L CNC Linear Milling Machine is delivered, the most advanced international measuring instruments are used to detect and correct the static and dynamic performance of the machine tool to ensure the high-quality characteristics of the equipment. Guangdong Taiwan Machinery designs professional samples of various machine models based on the user's processing characteristics, conducts processing tests on each piece of equipment, modifies various parameters of the equipment, and improves the processing adaptability of the equipment.
Reasons for choosing Guangdong Taiwan Machine
As a machine tool manufacturer, Guangdong Taiji Machinery designs machine models according to industry characteristics, accurately combines equipment performance with processing requirements, and achieves cost-effective features for user applications (you can choose a machine model based on processing accuracy, weight, efficiency and other characteristics to achieve the best price).
