Description of the basic structural features of the Lathe machine tool

1, Bed

The bed adopts an integrated high-low rail bed design, with a thick-walled, multi-ribbed, multi-cavity structure to ensure heavy cutting capabilities. The bed is cast with high-quality resin sand, with good rigidity, good shock resistance, and smooth chip removal.

2, Spindle box

The spindle bearing adopts a double-row short cylindrical roller bearing and a double-direction thrust angular contact ball bearing paired design. The three-speed gear in the servo main motor matching box realizes infinitely variable speed within the gear, achieving high torque and high rigidity, ensuring long-term precision stability of heavy cutting.
The spindle can be selected as a servo synchronous electric spindle with high torque, high speed and stable output. The spindle box bearing adopts a double-row cylindrical roller bearing and a double-direction thrust angular contact bearing, with high rigidity and heat dissipation. The corresponding structural design to reduce the thermal deformation of the spindle is adopted, so that the spindle can maintain the relative stability of the spindle axis during long-term operation.

3, Feed system

The X and Z axis servo motors are directly connected to the precision ball screw through elastic couplings, with high precision. The two ends of the screw are fixed, which improves the support stiffness of the support seat, minimizes the distortion of the screw caused by frequent high-speed positioning and heavy cutting, and the bearings use 60-degree angular contact pairs of precision bearings for screws, with high speed and high precision.

4, Slide

The transmission adopts imported linear rolling guides from Taiwan to meet the requirements of high speed and high efficiency, reduce friction resistance and temperature rise deformation, improve processing accuracy, and ensure the long-term stability of cutting processing accuracy.

5, Turret

The high-rigidity hydraulic servo turret is adopted. Through the servo system optimization compensation, it cooperates with the servo spindle to realize multi-axis linkage, which can complete spindle positioning, rigid tapping, curved surface milling and other functions, greatly enriching the functions of the machine tool, improving the adaptability of the machine tool, and meeting the processing needs of various parts.

6, Hydraulic system

In addition to program control, the clamping, loosening and telescopic extension of the hydraulic chuck and the tailstock sleeve can be controlled by foot, which is convenient and fast. Hydraulic pressure adjustment adopts panel-type rotary operation, dial display, safe and convenient adjustment.

7, Lubrication device

The machine tool adopts an automatic centralized lubrication system, with timed and quantitative oil supply. The oil distributor adjusts the oil supply pressure according to the pressure requirements of different lubrication parts to ensure that any lubrication parts (such as guide rails, inserts, screws, nuts and other friction pairs) can be fully lubricated, and the lubrication system alarm function is set.

8, Cooling system

The inclined bed CNC lathe adopts full guide rail protection, and the cooling box and chip conveyor are separated from the main machine to ensure that the machine tool accuracy is not affected by thermal cutting.

9, Electrical system

The machine tool electrical unit cabinet has good sealing performance and is equipped with an electrical cabinet air conditioner to ensure that the CNC system of the machine tool works normally under high temperature and high humidity environment.

10, Extreme anti-collision measures

The bearing seats at the extreme travel positions of the positive and negative directions of the axis are equipped with rubber buffer anti-collision devices to provide the final protection for the double nut ball screw pair from loss collision under abnormal conditions.

11, Safety protection

Fully protected inner sheet metal design and fully enclosed outer sheet metal design. The machine tool does not deform or vibrate when working. The inner protection guide rail, screw rod, nut and bearing are made of stainless steel telescopic cover. It is convenient to remove chips and clean machine chips.

Headstock Improvements are made to the heat dissipation air duct and heat sink of the spindle headstock, reducing the temperature rise of the spindle box by 15%. Spindle Speed: 2000rpm Spindle Power: 18.5kW Spindle Taper Hole: Ф86 mm

Guideway of the Bed The bed guideway adopts the 45° high-low rail structure used in Japanese-style machine tools, ensuring the rigidity, precision, and stability of the machine during heavy-cutting operations. The automated loading and unloading unit (if selected) is integrated with the machine, significantly reducing the floor space. X/Z-axis Travel: 270/600 mm X/Z-axis Rapid Traverse Speed: 25/25 m/min

Frequently Asked Questions

Q1: What is the Z600 / Z700 CNC Lathe Machine designed for?

The Z600 and Z700 CNC Lathe Machines are heavy-duty, large-capacity turning centres designed for machining large-diameter workpieces in industries such as energy, heavy engineering, mining equipment, shipbuilding, and large-scale automotive or industrial component manufacturing. The numerical designation — 600 and 700 — indicates the maximum turning diameter capacity of each model, making them the appropriate choice when workpiece diameter requirements exceed the capacity of mid-range turning machines.

Q2: What is the difference between the Z600 and Z700?

The primary difference between the Z600 and Z700 is maximum turning diameter capacity. The Z600 accommodates workpieces up to 600mm in diameter, while the Z700 extends this capacity to 700mm. Both machines share the same heavy-duty structural platform, control system options, and operational principles — the Z700 is selected when the workpiece diameter exceeds the Z600's 600mm capacity, or when future workpiece mix expansion into larger formats is anticipated.

Q3: What structural features give the Z600 / Z700 their heavy-duty capability?

The Z600 and Z700 derive their heavy-duty capability from a combination of a reinforced cast iron bed with wide guideway spacing for maximum rigidity, hardened and precision-ground guideways or linear roller guide systems, a high-torque headstock spindle motor capable of delivering sustained torque at low RPM for heavy material removal, a robust turret indexing system with high tool clamping force, and a chip conveyor system designed to handle the high chip volumes generated during aggressive large-diameter turning operations.

Q4: What CNC control options are available for the Z600 / Z700?

The Z600 / Z700 CNC Lathe Machines are available with FANUC 0i-TF, Siemens 828D, and GSK 988T control platforms, depending on market and customer specifications. All supported control systems provide full turning cycle capability, automatic tool compensation, threading and grooving cycles, and remote diagnostic capability. FANUC and Siemens platforms are recommended for applications requiring integration with factory-wide data systems or MES connectivity.

Q5: What is the maximum workpiece weight the Z600 / Z700 can support?

The Z600 and Z700 are engineered to support substantial workpiece weights at the spindle, with the specific capacity depending on chuck type, spindle bearing design, and machine configuration. For very heavy workpieces approaching or exceeding the spindle's rated load, a steady rest or tailstock centre support should be used to distribute load and maintain workpiece stability during machining. Confirm the maximum rated workpiece weight with the manufacturer before committing to the machine for particularly heavy applications.

Q6: Can the Z600 / Z700 perform threading and grooving operations?

Yes. Both the Z600 and Z700 fully support threading — including metric, imperial, and pipe thread standards — as well as internal and external grooving, parting, and taper turning as standard CNC operations programmed through the machine's turning cycle library. The spindle encoder provides the synchronisation required for accurate thread pitch generation across a wide range of thread types and pitches.

Q7: What industries most commonly deploy the Z600 / Z700?

The Z600 and Z700 are most commonly deployed in heavy equipment manufacturing — large pump housings, valve bodies, gearbox cases, and turbine components; the energy sector for large flanges, pipe fittings, and wellhead components; the mining industry for large sheave wheels, drum hubs, and crusher components; marine engineering for propeller shafts and large ring gear blanks; and any general heavy engineering facility producing large-diameter rotational components in low-to-medium volumes.

Q8: What are the key specifications to review when choosing between the Z600 and Z700?

The primary specification differentiator is maximum swing over bed — 600mm for the Z600 and 700mm for the Z700. Beyond diameter, evaluate maximum turning length (distance between centres), spindle bore diameter for bar-through applications, spindle motor power and torque at low RPM for heavy cutting, turret capacity and tool shank size compatibility, guideway type and hardening method, and available steady rest and follower rest specifications if long or slender workpieces are included in your production mix.
