Product Features

The XD-V40K’s performance is driven by its thoughtfully designed features, each tailored to enhance efficiency, precision, and usability. Below is a detailed breakdown of its core components:

Servo Turret System: Fast, Reliable Tool Changes

The lathe’s 12-station servo turret is a standout feature, engineered to reduce tool change time and support multi-step machining operations.

Tool Holder Compatibility: Comes with 4 standard tool holders, supporting 25×25mm square shank tools and a Φ32mm boring tool holder—accommodating a wide range of cutting tools (e.g., turning tools, threading tools, boring bars).

High Precision Alignment: The servo-driven mechanism ensures precise tool positioning, eliminating manual adjustment errors and contributing to the lathe’s ±0.002mm repeatability.

Efficiency Boost: Rapid tool changes (faster than manual or hydraulic turrets) reduce non-cutting time, making the XD-V40K ideal for complex parts that require multiple tool setups.

Hydraulic Tailstock: Stable Support for Long Shafts

The hydraulic tailstock addresses the challenge of machining long workpieces by providing consistent axial support, preventing deflection and ensuring dimensional accuracy.

Robust Construction: Features a 75mm diameter tailstock sleeve with a 80mm stroke (MT5 taper), offering strong holding force for workpieces up to 400mm in length.

Hydraulic Control: Automatically adjusts pressure to match workpiece weight, avoiding over-clamping (which can damage parts) or under-clamping (which causes vibration).

Versatile Machining: Enables stable processing of long shafts, such as automotive drive shafts or industrial rollers, that would otherwise warp during cutting.

High-Performance Control & Spindle

The XD-V40K’s control system and spindle work in tandem to deliver precise, powerful cutting:

Taiwan Shinetech 7TA Control: User-friendly interface with intuitive programming, supporting both G-code and conversational programming—ideal for operators of all skill levels. The absolute encoder system eliminates the need for homing cycles after startup, saving time.

11KW Servo Spindle: Delivers high torque at low speeds (for heavy cutting) and smooth operation at 3500r/min (for high-speed finishing). The A2-6 spindle taper ensures secure tool holder mounting, reducing runout and improving surface finish.

Rigid Mechanical Construction

Durability and stability are built into the XD-V40K’s design, ensuring long-term performance even in high-volume production:

Cast Iron Bed: High-density cast iron minimizes vibration during cutting, a critical factor for maintaining precision.

High-Quality Motion Components: Uses Taiwan Hiwin ball screws (Φ32mm) and linear guides (X-axis: 30mm; Z-axis: 35mm)—these components reduce friction, enable fast rapid traverse speeds (18m/min for both X and Z axes), and extend service life.

Compact Footprint: Despite its capabilities, the lathe has a compact 2425×1781×2005mm (L×W×H) design, saving floor space in workshops.

Automation Compatibility

To support unmanned production, the XD-V40K integrates seamlessly with common automation tools:

Bar Feeders: Compatible with automatic bar feeders to process long bar stock without manual loading.

Parts Catchers: Works with parts catchers to collect finished parts, reducing operator intervention.

Industrial Robots: Can be paired with robotic arms for loading/unloading, further increasing production efficiency.

Applications

The XD-V40K High-Precision Servo Turret CNC Lathe with Hydraulic Tailstock is versatile enough to serve multiple industries, particularly those requiring tight tolerances and consistent part quality.

Automotive Component Manufacturing

Key Applications: Machining of drive shafts, half shafts, gear hubs, and brake components.

Why XD-V40K?: The lathe’s ±0.002mm accuracy ensures that automotive parts meet strict safety standards, while the 12-station servo turret handles the multiple tool changes needed for complex geometries (e.g., threaded ends, stepped shafts). The hydraulic tailstock supports long drive shafts (up to 400mm) without deflection.

Aerospace Precision Parts

Key Applications: Production of small aircraft components, such as engine shafts, sensor housings, and fasteners.

Why XD-V40K?: Aerospace parts often require machining of high-strength materials (e.g., titanium alloys, stainless steel). The 11KW servo spindle provides sufficient power for heavy cutting, while the Taiwan Shinetech 7TA control system ensures precise programming for intricate designs.

Medical Device Production

Key Applications: Manufacturing of surgical instrument components (e.g., scalpel handles, drill bits) and implantable parts (e.g., orthopedic screws).

Why XD-V40K?: Medical parts demand ultra-high precision and smooth surface finishes to avoid patient harm. The XD-V40K’s repeatability accuracy and high-speed spindle (3500r/min) deliver the required quality, while its enclosed design reduces contamination risks.

General Machinery Fabrication

Key Applications: Machining of industrial gears, pump shafts, valve bodies, and bearing housings.

Why XD-V40K?: The lathe’s max swing diameter of Φ500mm accommodates large parts like valve bodies, while the hydraulic tailstock supports long pump shafts. Its automation compatibility also makes it suitable for high-volume production of standard machinery components.

FAQ

What makes the XD-V40K suitable for long-shaft machining?

The XD-V40K’s hydraulic tailstock is the primary reason it excels at long-shaft machining. With a 75mm diameter sleeve and 80mm stroke (MT5 taper), the tailstock provides stable axial support for workpieces up to 400mm in length. Unlike manual tailstocks, the hydraulic design automatically adjusts pressure to match the workpiece’s weight, preventing deflection during cutting—critical for maintaining the ±0.002mm accuracy required for long shafts.

How does the 12-station servo turret improve machining efficiency?

The 12-station servo turret reduces non-cutting time by enabling fast, precise tool changes. Unlike hydraulic turrets (which rely on fluid pressure and can have lag), servo-driven turrets use electric motors for instant positioning. This means the XD-V40K can switch between up to 12 different tools (e.g., turning, threading, boring) in seconds, eliminating the need for manual tool adjustments. For complex parts that require 5+ tool changes, this can cut production time per part by 20–30% compared to lathes with fewer tool stations.

What is the repeatability accuracy of the XD-V40K, and why does it matter?

The XD-V40K has a repeatability accuracy of ±0.002mm—a measure of how consistently it can return to a specific position after tool changes or startup. This matters because industries like automotive, aerospace, and medical require identical parts batch after batch. A repeatability of ±0.002mm ensures that even small features (e.g., 0.5mm threads, 1mm stepped diameters) are consistent across hundreds or thousands of parts, reducing scrap rates and ensuring compliance with industry standards.

Can the XD-V40K integrate with automation systems for unmanned production?

Yes, the XD-V40K is designed for automation compatibility. It works seamlessly with:

Automatic bar feeders: For continuous processing of long bar stock (up to Φ51mm diameter) without manual loading.

Parts catchers: To collect finished parts, reducing operator intervention.

Industrial robots: For automated loading/unloading, which is ideal for 24/7 production runs. This integration not only increases output but also reduces human error, further improving part consistency.
