The machine bed, column, worktable, sliding carriage, and tailstock are all made from high-strength resin sand gray cast iron. The ram saddle and ram (if applicable by model) are made from high-grade ductile iron. All these major castings undergo two heat treatment (thermal aging) processes.

The spindle consists of a boring spindle and a milling spindle, using imported spindle bearings. The main drive system employs an AC servo motor combined with a two-stage mechanical transmission to achieve stepless speed regulation. The spindle material is 38CrMoAlA, surface-nitrided, ground, and polished to a final hardness exceeding HV900.

This device allows for arbitrary angle positioning. The rotary axis uses double-row cylindrical roller bearings, with a central unloading device on the upper part of the axis system. The rotary feed mechanism is driven by an AC servo motor, which actuates a large gear ring via a backlash-eliminating reducer and double gears. This structure automatically eliminates gear transmission backlash, ensuring high transmission accuracy. During machining, hydraulic floating clamping is used for reliable and convenient operation, guaranteeing the stability of the oil film thickness.

Option 1: Heavy-duty roller linear guideways for X, Y, and W axes; a plastic-coated sliding guideway for the B-axis; and a wrapped sliding guideway for the V-axis.

Option 2: Hydrostatic guideways for X, Y, and W coordinate axes, for heavy cutting operations.

The X, Y, Z, V, and W coordinate axes feed mechanisms are driven by AC servo motors. They consist of precision zero-backlash reduction gearboxes and preloaded double-nut ball screw pairs, effectively eliminating reverse backlash.

A center of gravity follow-up compensation device is used to compensate for errors caused by shifts in the ram's center of gravity when attachments are installed or when the ram is extended.

An electro-hydraulic balance compensation device also compensates for these errors.

Ram pre-deformation compensation is achieved by using a pre-deformation machining process to counteract the deflection caused by the ram's self-weight when extended.

Compensation is also provided by the electrical control system.

One hydraulic station, equipped with a constant temperature oil cooler, handles the lubrication and cooling of the headstock and spindle. Another hydraulic station serves functions such as spindle speed change, tool release, and rotary table clamping. If hydrostatic guideways are selected, they share a hydraulic station with the headstock cooling system for hydraulic oil supply. All hydraulic components meet international standards for installation dimensions.

The X, Y, Z, B, V, and W coordinate guideways and ball screw nut pairs are lubricated by a timed, quantitative automatic lubrication device. The spindle transmission gears and bearings are lubricated by circulating cooling oil. The spindle front bearings and screw bearings are lubricated with grease.

The CNC system can provide six-axis control with arbitrary four-axis linkage. It includes a handheld control unit with a display. The system can also control and manage optional accessories such as a face plate (U-axis), tool magazine, and probes.

Grating scales are used for the X, Y, and W axes, and a circular grating is used for the B-axis, constituting a full closed-loop position detection system. Encoders are used for the V and Z axes, forming a semi-closed-loop position detection system (this is an optional configuration).
