CNC vertical lathe specifications

The VTC50 and VTC60 are suitable for machining medium-sized rotating parts, including flanges, hubs, brake discs, and other components.
The VTC70 and VTC80 offer a larger machining range for larger-diameter discs, rings, and engineering machinery parts.
For workpieces with diameters of up to Φ1000 mm, the VTC100 provides the largest machining range in the series and is equipped with a 37 kW spindle motor, making it suitable for larger workpieces and higher cutting loads.
The appropriate machine model can be selected based on the maximum workpiece diameter, machining height, material, weight, and required machining operations.

VTC Series Configuration Options

Depending on the application, available configuration options may include:

• Different hydraulic chuck sizes

• Different turret capacities

• CNC control system options

• Spindle motor configurations

• Cooling system options

• Chip removal equipment

• Workholding accessories

CNC System Selection

The VTC series can be configured with different CNC systems according to customer preferences and project requirements.
The standard configuration uses a GSK system, while KND, FANUC, Siemens, and other CNC systems are also available according to customer requirements.
For factories already using a specific CNC system, selecting the same or a compatible system for new equipment allows operators to continue using their existing programming knowledge and operating experience.

VTC50: 15″ / 18″
VTC60: 18″ / 21″
VTC70: 21″ / 24″
VTC80A: 24″ / 32″
VTC100A: 32″ / 40″

Chuck sizes range from 15 to 32 inches and can be selected according to the workpiece clamping diameter, weight, and clamping method.
For large flanges, hubs, and ring-shaped parts, the jaw specifications and clamping method can be further determined based on the workpiece drawings.

For parts such as discs, flanges, gear blanks, hubs, and valve bodies, vertical clamping allows the workpiece to rest securely on the worktable or chuck under its own weight. For heavier parts, this layout makes loading and unloading easier.

Complete More Processes in a Single Workpiece Setup

 

01

 

The value of a vertical lathe lies not only in its ability to machine large workpieces, but also in its ability to reduce the need to transfer workpieces between different machines.

 

02

 

For a typical disc-shaped part, a single clamping operation can accommodate external turning, end-face machining, internal machining, step turning, and grooving, depending on the turret configuration.

 

03

 

If a workpiece requires frequent reclamping, each repositioning can add auxiliary time and require additional alignment.

Cooling Systems Do More Than Control Temperature
In addition to helping control the temperature around the tool and workpiece during machining, the cooling system also helps flush away chips and maintain a cleaner machining area.
When configuring the machine, the cooling system requirements can be determined based on the workpiece material, cutting tool, and machining process.
Conventional turning can generally use standard cooling methods. Deep-hole machining or continuous heavy cutting may require greater cooling capacity. When machining aluminum alloys, effective chip flushing is particularly important. For cast iron, both chip removal and coolant management should be taken into account.

Safety and Protection Functions

The machine tool is equipped with a fully enclosed protective structure that separates the machining area from the operator. The protective door features reinforced glass for clear visibility while helping protect personnel from chips, coolant, and other splashes generated during machining, providing a safer working environment for daily operation.

The CNC system includes protection functions for power outages and system malfunctions. In the event of a sudden power outage or system malfunction, all machine axes remain stopped, while auxiliary equipment such as the coolant pump also stops operating. When power is restored, the equipment that was shut down will not restart automatically, helping prevent unexpected machine movements caused by power recovery. Machining programs and related data stored in the CNC system are also retained after a sudden power outage.

The machine is also equipped with an emergency stop button and fault alarm function to notify the operator of abnormal conditions during operation. When an alarm is triggered, the CNC display shows the corresponding alarm message and code, while the indicator lights on the control panel provide additional status information. This allows the operator to quickly identify the current machine status.

The system uses different responses according to the severity of the fault or operating error. A serious fault triggers an emergency stop and immediately halts machine operation. A general fault places the machine in a feed-hold state, pausing the machining operation. For operating errors, the system displays a prompt to guide the operator in correcting the error and help avoid unnecessary downtime.

Management of Wear Parts and Spare Parts

During long-term operation, certain seals, lubrication components, filter elements, and mechanical and electrical parts may undergo normal wear due to operating time and workload. Regular inspection of these components helps identify potential problems early and maintain stable machine operation.
For different machine models and configurations, we can prepare corresponding spare parts lists based on the equipment model. These lists include commonly used wear parts and related components, making subsequent maintenance and spare parts procurement more convenient.
For customers with continuous production or long-term machine operation, we recommend keeping commonly used wear parts in stock according to their actual replacement frequency. Maintaining a reasonable spare parts inventory can reduce procurement and delivery waiting times and allow worn components to be replaced more quickly, helping reduce unplanned downtime caused by spare parts shortages.

Installation & Operating Requirements

To ensure stable operation and proper machine performance, the CNC vertical lathe should be installed and operated under the following conditions:

Power Supply: Three-phase AC 380 V ±10%, 50 Hz.
Ambient Temperature: 10–40 °C.
Relative Humidity: ≤85%.
Workshop Environment: The machine should be installed in a clean workshop free from corrosive gases, liquids, and excessive dust.
Hydraulic Oil: The user should prepare No. 32 hydraulic oil required for machine operation.
Installation Site: The foundation and surrounding area should be free from significant sources of vibration, dust, and electromagnetic interference.
Consumables: The user should prepare basic consumables required for daily operation and maintenance, such as cleaning agents, cotton cloths, and other cleaning materials.

A suitable installation environment helps maintain machining accuracy, operating stability, and machine service life.

About Us

Our Certificate

 

 

Each machine undergoes inspection before delivery

After assembly, the machine undergoes accuracy checks, operational tests, and functional verification based on its specific configuration. These checks cover machine movements, spindle operation, turret movement, hydraulic systems, and cooling systems.

For projects with specific machining requirements, trial cutting can be carried out using workpieces or machining drawings provided by the customer. This helps identify and address potential issues before shipment.

After inspection, the machine is treated for rust prevention and prepared with waterproof, cushioning, and export packaging for long-distance transportation.

The company holds CE and ISO 9001 certifications and has extensive experience serving overseas markets. Power supply specifications, CNC systems, technical documentation, and equipment configuration requirements for different countries and regions can be confirmed before production.
