CNC vertical lathes/vertical turning centers Ø2500-4000

Product Introduction

Ideal for machining large, thin, heavy, and irregularly shaped parts, facilitating easy loading and unloading.
Due to the workpiece's own weight, the fixture ensures intimate contact, allowing for high-precision and stable machining results; workpiece loading/unloading time is short and stable.
Eliminates elliptical machining caused by the self-weight inertia during clamping in horizontal lathes, achieving extremely high roundness precision.
Enables stable machining of difficult-to-clamp, irregular workpieces. Fixture structure is simple, resulting in lower manufacturing costs.
Machine features a near-square, high-rigidity design, minimizing the impact of thermal displacement and vibration. Increased chip angle, stainless steel sheet material ensures smooth chip evacuation and prevents bed thermal deformation.
Three-dimensional assembly line conforms to ergonomics, facilitating workpiece handling.
Floor space requirement is 50% less compared to horizontal lathes.
Multi-functional configuration, optimal operation, and lowest investment cost.

No.	VTL Vertical Lathe	Advantage
1	FANUC-0i-TF Plus Control System ---- Machining Accuracy IT6
2	The spindle (worktable) uses crossed roller bearings, ensuring high radial and axial load capacity at both high and low speeds, achieving high precision, low noise, and durability. Features high precision, high load capacity, and high rigidity, suitable for large workpieces and asymmetric parts.	Improved worktable rotational accuracy, speed 200/320rpm
3	Z-axis utilizes a cylindrical ram with a large cross-section design, employing rolling + sliding composite guideways, ensuring machine rigidity and machining accuracy. Equipped with a hydraulic counterbalance automatic system to ensure accuracy during large height and deep bore machining. Built-in machining center coolant through-spindle outlet ensures tool cooling and increases tool life.
4	XZ axes use Japan THK C3 class precision ball screws paired with Japan NSK precision angular contact ball bearings with preload, long-type double nut preload.	Ensures excellent positioning accuracy
5	The main drive is powered by a wide-range spindle servo motor, driven through a two-speed gearbox (auto 2-range) and high-precision two-stage gears.	Low noise, high reliability
6	ATC Tool Magazine: Automatic tool clamping structure. Uses a Hirth coupling mechanism, with perfect mating of male/female parts, maximizing rigidity during turning, especially during interrupted cuts, firmly holding the tool holder against the square ram.
7	4/5/6-station --- Servo Hydraulic Turret (Hydraulic clamping force 9100Kgf; Electric tool post clamping force 2000Kgf)	Good rigidity, fast indexing
8	X/Z axis rapid traverse 12m/min	Fast traverse speed (others 2m/min), sufficient lubrication
9	Machine external guarding adopts double-door structure	Minimizes machine footprint
10	Optional X-axis closed-loop linear scale
11	Optional Z-axis closed-loop linear scale
