Three VTC160100 Configurations


VTC160100Q – General-Purpose

The manufacturer positions the VTC-Q Series as a cost-effective, convenient-to-operate general-purpose vertical lathe.

Key characteristics include:

• High rigidity

• Large torque

• Stable machining

• Practical general-purpose configuration

• Cost-effective machine selection

Typical industries include:

• Pump and valve

• General industry

• Engineering machinery


The Q configuration is best suited where:

• General turning is the main requirement

• The workpiece fits comfortably within the VTC160100 envelope

• Turn-milling is not required

• Overall machine value is important

• A practical general-purpose vertical lathe is preferred


VTC160100H – High-Efficiency

The VTC-H Series is the higher-efficiency platform.

The manufacturer highlights:

• Excellent rigidity

• High stability

• Higher machining accuracy

• High production efficiency

• Higher-quality functional components

Typical applications include:

• Wind power

• New energy

• Automotive

• Bearing manufacturing


The H configuration is best suited where:

• Production stability is more important

• Higher machining accuracy is required

• Higher production efficiency is valuable

• More demanding workpieces are expected


VTC160100Hm – Turn-Milling

The Hm configuration adds:

• Powered milling spindle

• C-axis operation

• Automatic tool magazine

• Expanded radial machining range

This allows selected turning and milling processes to be completed in one setup.


Best suited where:

• Turning and milling are both required

• Bolt-circle holes are present

• Face features need milling

• Drilling and tapping are required

• C-axis positioning is beneficial

• Re-clamping should be reduced


Why Turn-Milling Matters

Large ring, flange and disc components often require machining on several different machines.

A conventional process may involve:

• Vertical turning

• Crane unloading

• Transfer to milling machine

• Re-clamping

• Re-establishing datum

• Drilling

• Tapping

• Inspection


The VTC160100Hm can potentially combine selected operations in one setup.

Benefits can include:

• Reduced crane handling

• Reduced workpiece movement

• Reduced re-clamping

• Improved datum consistency

• Reduced setup time

• Lower work-in-process time

• Better positional relationship between turned and milled features


Typical Hm Operations

• External turning

• Internal turning

• Facing

• Grooving

• Profile turning

• Face milling

• Drilling

• Tapping

• Bolt-circle machining

• Indexed milling

• C-axis positioning


High-Rigidity Casting Structure

The VTC Series uses box-type integrated cast-iron construction.

The manufacturer highlights:

• Thick-wall construction

• Reinforced rib structure

• Low centre of gravity

• Heat treatment for residual-stress relief

• Precision scraping of important mating surfaces


This structure is intended to maintain machining accuracy and stability during heavy cutting.


High-Rigidity Hard Guideways

The two principal feed axes use:

• High-rigidity hard guideways

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

Benefits include:

• High rigidity

• Strong load-bearing capacity

• Good accuracy retention

• Stable heavy cutting

• High resistance to cutting-force deformation


The manufacturer specifically positions this structure for heavy-load machining.


240 × 240 mm Forged-Steel Ram

The VTC160100 uses a:

• 240 × 240 mm forged-steel ram

The ram surface is hardened and the guideway mating surfaces are precision scraped.

The manufacturer identifies the newer ram structure as substantially enlarged compared with the previous generation.

Benefits include:

• Increased bending rigidity

• Greater torsional stiffness

• Stable vertical machining

• High positioning accuracy

• Improved resistance to cutting torque


High-Rigidity Main Machine Structure

The beam, column and ram-support system are designed for high-rigidity and heavy-load machining.

The manufacturer highlights:

• Increased column thickness

• Increased guideway span

• Reinforced beam construction

• Improved resistance to ram leverage forces


These measures help maintain machining stability on larger rotary workpieces.


Symmetrical Thermal Structure

The base and column follow a left-right symmetrical layout.

The design aims to provide:

• Balanced heat distribution

• Reduced thermal deformation

• Better long-term geometric stability


Finite-element topology analysis is used to optimise the machine structure.

Internal mesh-style ribs further increase structural rigidity.


Crossed-Roller Worktable Bearing

The VTC Series uses a high-accuracy large-specification crossed-roller bearing.

The bearing arrangement is designed to withstand combined:

• Axial load

• Radial load

• Workpiece mass

• Cutting load

• Workbench torque


The manufacturer identifies this as an important contributor to:

• Strong workbench support

• High rigidity

• Fast positioning

• High-speed and high-torque cutting


High-Accuracy Main Transmission

The main transmission uses a geared arrangement instead of a simple belt-only drive.

The manufacturer highlights:

• Accurate segmentation

• Positioning capability

• High stability

• Turn-milling capability

• C-axis functionality on applicable machines


A constant-temperature cooling device is incorporated in the spindle system to reduce thermal axial displacement.


Double-Motor Workbench Drive

The VTC platform uses two main motors to drive the workbench.

The CNC system synchronises the two motors.

This arrangement helps provide:

• Stable table rotation

• Accurate indexing

• High torque

• C-axis anti-backlash control

• Stable surface quality

• Turn-milling speed regulation


Automatic Tool Change

Where required, the VTC platform can use a suspension-disc tool magazine.

The VTC160100Hm configuration provides:

• 16-tool magazine

This supports automatic tool changes for processes such as:

• Milling

• Drilling

• Tapping

• Boring

• Multi-process machining


Turn-Milling Modularisation

The VTC Series uses a modular turn-milling design.

The slide structure is compatible with both:

• Turning ram

and

• Turn-milling ram


This allows the machine configuration to be matched more closely to the actual production requirement.


Machine Layout Advantage

The manufacturer also provides modular layout concepts including:

• Single-ram configuration

• Double-ram configuration on applicable machines

The double-ram concept is intended for higher machining efficiency where suitable.

Final configuration availability should be confirmed for the selected VTC160100 machine.


Installation Advantage

An important manufacturer-documented feature is that:

• VTC160 and smaller specifications can be lifted as a complete machine

This can help reduce:

• Installation work

• On-site assembly

• Commissioning time


This is an important practical difference between VTC160100 and the larger VTC200140-and-above machines.


Typical Turning Operations

The VTC160100 can support:

• External turning

• Internal turning

• Facing

• Grooving

• 400 mm greater turning diameter

• 200 mm additional workpiece height

• Substantially greater workbench torque

• Larger 240 × 240 mm ram

• Greater radial travel


Both remain available as:

• Q

• H

• Hm


VTC160100 Compared with VTC200140

This is an especially important model boundary.


VTC160100

• Q / H / Hm available

• Workbench: Ø1600 mm

• Maximum turning diameter: Ø1800 mm

• Maximum workpiece height: 1200 mm

• Workbench torque: up to approx. 22,960 Nm

• Main motor: up to 41 kW

• Ram: 240 × 240 mm

• Beam movement: 800 mm

• Z travel: 1000 mm

• Machine weight: approx. 26 tonnes


VTC200140

• H / Hm only

• Workbench: Ø2000 mm

• Maximum turning diameter: Ø2300 mm

• Maximum workpiece height: 1600 mm

• Workbench torque: approx. 49,800 Nm

• Main motor: 51 kW

• More than double the workbench torque

• Higher main motor power

• Much larger beam and Z-axis capacity

• Machine mass increasing from approximately 26 to 45 tonnes
