The principal feed axes use:

• High-rigidity hard guideways

The guide surfaces receive dedicated treatment and low-friction wear plates.

Benefits include:

• Strong load-bearing capacity

• High rigidity

• Stable heavy cutting

• Good accuracy retention


200 × 200 mm Forged-Steel Ram

The VTC125100 uses a:

• 200 × 200 mm forged-steel ram

The ram is designed to provide:

Compared with the larger VTC160100, the VTC125100 uses a smaller ram appropriate to its workpiece class.


Symmetrical Thermal Structure

The base and column use a left-right symmetrical structure.

This is intended to improve:

• Thermal balance

• Geometric stability

• Long-cycle accuracy consistency


The internal structure is reinforced to increase overall rigidity.


Crossed-Roller Worktable Bearing

The VTC platform uses a high-accuracy crossed-roller worktable bearing.

This arrangement supports:

• Axial load

• Cutting force

• High workbench torque


This provides stable support for large rotary components.


High-Torque Main Drive

The VTC125100 provides approximately:

• 15,480 Nm torque on Q

• 15,626 Nm torque on H

Combined with:

• 37 / 41 kW main motor

this provides useful heavy-turning capability for the 1.4 m turning class.


High-Accuracy Main Transmission

The main transmission uses a geared drive concept.

This supports:

• High torque

• Stable speed control

• Accurate indexing

• C-axis operation on Hm

• Turn-milling integration


Spindle temperature-control measures are used to reduce thermal influence during extended machining.


Double-Motor Workbench Drive

The VTC platform uses synchronous control of dual main motors for workbench drive.

Benefits include:

• Stable table rotation

• Improved indexing performance

• C-axis anti-backlash

• Stable surface quality


Turn-Milling Modularisation

The VTC Series uses a modular turn-milling design.

The machine slide can accommodate:
