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 bearings are designed with a combination of double-row short cylindrical roller bearings and double-direction thrust angular contact ball bearings. The servo main motor features stepless speed variation, achieving high torque and high rigidity, ensuring long-term precision stability during heavy cutting.

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 machine is equipped with a high-rigidity hydraulic servo tool turret, which, through servo system optimization and compensation, works in conjunction with the servo spindle to achieve multi-axis interpolation. This enables functions such as spindle positioning, rigid tapping, and surface milling, significantly enhancing the machine tool's functionality and adaptability, thereby meeting the processing requirements 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.

Frequently Asked Questions

Q1: What are the differences between the T55, T55L, and T55M variants?

The T55 is the standard configuration CNC slant bed lathe offering high-accuracy turning within a defined turning length range suitable for general-purpose precision machining. The T55L is the long-bed variant, extending the distance between centres to accommodate longer shafts, rollers, lead screws, and other elongated workpieces that exceed the standard machine's capacity. The T55M incorporates a milling turret or live tooling unit, enabling the machine to perform powered milling, drilling, and tapping operations in addition to turning — effectively making it a turn-mill centre capable of complete part machining in a single setup.

Q2: What accuracy level can be expected from the T55 series?

The T55 series is engineered to deliver positioning accuracy and part-to-part repeatability consistent with high-accuracy classification. Precision-ground ball screws, hardened guideways, a low-runout spindle, and closed-loop CNC feedback collectively enable the machine to maintain dimensional tolerances appropriate for precision automotive, hydraulic, and aerospace components. Specific accuracy figures — including positioning repeatability and spindle runout — are available in the machine's technical specification sheet.

Q3: What types of workpieces are best suited to the T55 series?

The T55 standard variant is best suited for disc-shaped and short cylindrical workpieces, including flanges, bearing rings, couplings, and valve bodies. The T55L extends the capability to long shafts, spindles, cylinders, and roller components requiring support between centres or a steady rest. The T55M adds suitability for complex multi-feature parts requiring off-centre holes, milled flats, keyways, and radial or axial drilling in a single clamping operation.

Q4: Does the T55M support Y-axis or C-axis machining?

The T55M is configured with a powered live tooling turret and C-axis spindle control as standard, enabling radial and axial milling, drilling, and tapping at precise angular positions around the workpiece. Y-axis capability — for off-centre milling operations — may be available as an optional upgrade on the T55M platform, depending on manufacturer configuration. Confirm Y-axis availability with the supplier when specifying complex part requirements.

Q5: What CNC control options are available for the T55 series?

The T55 / T55L / T55M series is available with FANUC 0i-TF, Siemens 828D, and GSK control systems, depending on the variant and market. The T55M with live tooling requires a control platform that supports C-axis and milling cycle functionality, which is provided as standard on FANUC 0i-TF and Siemens 828D configurations.

Q6: What is the bar capacity of the T55 series?

The bar capacity — the maximum diameter of bar stock that can pass through the spindle bore — varies by T55 series configuration. This specification is critical for bar-fed automatic production operations and should be confirmed against the diameter of bar stock used in your application when selecting between variants.

Q7: Is the T55 series compatible with automatic bar feeders?

Yes. All three variants in the T55 series — T55, T55L, and T55M — are designed for compatibility with short and long bar feeder systems. The CNC control communicates with the bar feeder via M-code or a dedicated interface, enabling automatic bar advancement between parts and supporting extended unmanned production runs without operator intervention.

Q8: What are the key buying considerations when choosing between T55, T55L, and T55M?

The primary selection factors are workpiece length requirements (T55 vs T55L), part complexity and the need for milling or drilling operations within the lathe (T55 vs T55M), production volume and automation needs, and budget. The T55 offers the best value for standard precision turning. The T55L is essential when the workpiece length exceeds the standard machine capacity. The T55M delivers the highest per-part value in complex, multi-feature production environments where reducing setups and machine transfers directly impacts cost and lead time.
