FEATURES

01Applications

Designed for ordinary milling, drilling, tapping boring, and the processing for ID, OD, ladder, sphere, groove, 2D, and 3D complex shapes.

Can process many kinds of materials of blanks in both rough and precision modes, such as high-temperature alloy, titanium alloy, heat resistant alloy, stainless steel, and casted iron.

Good system rigidity, reliability, accuracy, and longer lifespan. The machine can process roughing, fine processing, and finishing. Moreover, it can process various difficult materials.

02Product features

Fast working pallet changer mechanism

Front pallet exchange in front of the X-axis. There is a button panel for workpiece clamp operation.

Two-section worm gear set

Special gear design leads to double gear contact numbers which are five times the contact surface, so that the pressure on worm gear is one fifth only, with lesser wear out rates.

The worm body is designed as two-part, and the space between gears is simpler with the width within 5~8μ.

The worm gear material is made of phosphor bronze, that is with lower friction rates, so the tenacity is improved; with stress relief procedure, the material quality is much more stable and is suitable for higher loading and higher accuracy demands.

The pressure angle is much smaller than the dual lead for around 12°, so the motor torque can be fully utilized unto steering torques, which is suitable for synchronized continual cutting.

Air-blow cleaning system

The design of the worktable adopts four conical positioning seat holding mechanisms, which are fast and accurate in positioning. The strong force ensures the stability and positioning accuracy of the worktable. The powerful air blowing system blows out the airflow from the conical positioning seat, removing the iron materials; the cone seat is used to perform a low-pressure inspection to ensure the stability and positioning accuracy of the worktable

The sealed cone-shaped design is not an open design, so it ensures both the cutting fluid and cutting movement will not go further into the taper sleeve when the worktables are exchanging. The design ensures strong holding force and great precision for a longer time.

Direct drive spindle

Spindle torque diagram

The imported spindle bearing components are of high rigidity and high precision, which are suitable for heavy cutting.

Maximum spindle speed 8000RPM.

Machine photo 1

The machine tool is composed of a worktable, base, vertical column, spindle box, and APC. It also incorporates a hydraulic system, cooling system & chip conveyor, lubrication system, and electrical system. The direct rotational worktable increases productivity.

Machine photo 2

The movement of the spindle box is on the vertical column and the electrical system is equipped with six axes or synchronized three/ four axes functionality.

The design of Y-axis adopts high rigidity ladder cross structure, installed under the T traverse base; the rotational B axis is installed under base for the forward and backward movement of the Z-axis. The three axes are of heavy bearing competence due to their roller guides, which are supported by four sliding blocks. By minimizing the surfaces of the guides, the gravity is lowered and the rigidity is reinforced. Furthermore, while under high speed and high accuracy control, it's excellent axial movement accuracy is also high, which is realized by low friction, high reliability, small mass, and little inertia.
