NEW SMTCL V8H CNC Vertical Lathe

NEW SMTCL V8H CNC Vertical Lathe

HEAVY-DUTY HIGH-EFFICIENCY CNC VERTICAL LATHE FOR LARGER DISC, RING, HUB AND FLANGE COMPONENTS

The SMTCL V8H is the largest model in the V Series high-efficiency CNC vertical lathe range.

It is designed for larger and heavier disc-type, ring-type, hub, flange and housing components where vertical workholding, machine rigidity and production efficiency are more important than long-shaft capability.

Compared with the V6H, the V8H increases maximum turning diameter from 600 mm to 850 mm and maximum turning height from 650 mm to 850 mm, while using a substantially larger 21 inch standard chuck and heavier machine structure.

For suitable components, the vertical spindle arrangement allows the workpiece to sit naturally on the chuck under gravity, helping simplify loading and workholding compared with a conventional horizontal lathe.

The V8H is best positioned as a large-capacity production vertical lathe, sitting between the more compact V6H and SMTCL's much larger VTC table-type vertical lathe range.

• Main motor output: 22 / 30 kW
• X-axis travel: 480 mm
• Z-axis travel: 850 mm
• X / Z rapid traverse: 18 / 18 m/min
• Standard tool carriage: horizontal 8-station servo
• Approximate machine weight: 10,500 kg


WHY USE A VERTICAL LATHE?

The main advantage of a vertical lathe is the orientation of the workpiece.

Instead of hanging a large disc or ring component vertically from a horizontal chuck, the component sits flat on a vertically oriented spindle.

For suitable workpieces, this offers several practical advantages:

• Gravity assists workpiece seating
• Easier loading of large-diameter components
• Reduced tendency for heavy parts to sag during setup
• Better accessibility to disc and ring-type components
• Practical chucking of irregular rotational castings
• Efficient chip flow away from the cutting zone
• Good compatibility with robotic or gantry loading

The V8H is therefore particularly attractive where component diameter is significant relative to component length.


HIGH-RIGIDITY MACHINE STRUCTURE

The V Series is SMTCL's upgraded CNC vertical lathe platform and is designed around rigidity, stability and machining accuracy.

Key structural features include:

• High-rigidity cast machine body
• Resin-sand cast base
• Large-span column
• Reinforced column structure
• Roller linear guideways
• Low centre-of-gravity layout
• Thermally balanced spindle structure
• Large chip-removal angle
• Scraped critical joint surfaces

For the V8H, this heavier structure is particularly important because the machine is intended to support larger chucks, larger workpieces and higher cutting loads than V4H or V6H.


LARGE-SPAN COLUMN DESIGN

SMTCL uses a wide-span column structure across the V Series.

The broader support arrangement improves resistance to deformation under cutting load and helps maintain stability during heavier turning.

For V8H applications, this becomes particularly relevant when machining:

• Large flange faces
• Large bores
• Heavy castings
• Large-diameter interrupted cuts
• Components with significant overhang from the chuck
• Deep internal features

The purpose is not simply to increase machine mass, but to maintain predictable tool-to-workpiece geometry under load.


ROLLER LINEAR GUIDEWAYS

Both feed axes use roller linear guideways.

Roller guideways provide higher stiffness and load capacity than lighter ball-type guide systems and are well suited to heavier vertical turning applications.

The result is a machine better suited to applications where:

• Cutting forces are substantial
• Workpieces are large
• Stable finish is required
• Tool overhang cannot always be minimised
• Productivity requires higher material-removal rates


HIGH-PERFORMANCE SPINDLE

The V8H uses a lower-speed spindle than the V6H because its application priority shifts toward larger diameter and heavier workpieces.

• Maximum spindle speed: 1,500 rpm
• Main motor: 22 / 30 kW
• Standard A2-11 spindle nose
• Optional A2-15 configuration
• Standard 21 inch chuck
• Optional 24 inch and 32 inch chuck configurations

The spindle incorporates high-precision bearings and is designed to provide stable machining under relatively high radial loads.

SMTCL also uses a multi-speed servo concept to provide a practical balance between torque and rotational speed for different workpiece diameters.


HIGH-EFFICIENCY 8-STATION SERVO TOOL CARRIAGE

The standard V8H uses a horizontal 8-station servo tool carriage.

SMTCL identifies the fast indexing system as one of the key productivity features of the V Series.

Manufacturer data indicates:

• Adjacent station indexing: approximately 0.25 seconds
• Maximum station indexing: approximately 0.79 seconds
• High repeatability of tool positioning

This reduces non-cutting time during repetitive production where multiple tools are required.


OPTIONAL TOOL-CARRIAGE CONFIGURATIONS

Depending on the application, alternative tool-carriage configurations may be available.

These can include:

• Horizontal 8-station servo tool carriage
• Horizontal 12-station tool carriage
• Vertical 5-station tool carriage
• Vertical 6-station tool carriage
• Power tool carriage
• Integrated tool carriage

A vertical tool carriage may be considered where additional rigidity is required, particularly for deep internal machining.


POWER TOOLING OPTION

For components requiring selected secondary operations, powered tooling can be configured.

Depending on final specification, powered tooling may support:

• Drilling
• Milling
• Tapping
• Face drilling
• Radial drilling
• Simple slots
• Simple milled flats
• Bolt-circle features

0° and 90° power toolholder arrangements can be selected according to the machining requirement.

This can reduce the need to move suitable components to a separate machining centre after turning.


TURN-MILLING OPTION

The V Series can also be configured with a turn-milling spindle.

This allows a wider range of operations to be completed with the component remaining in the same workholding setup.

Potential advantages include:

• Reduced re-clamping
• Reduced handling
• Reduced datum transfer
• Fewer machines involved in the process
• Improved positional relationship between turned and milled features
• Reduced work-in-progress
• Shorter total manufacturing time

However, turn-milling capability should only be specified where the actual component requires it.

For components requiring predominantly turning, the standard V8H configuration may provide better value.


ATC TOOL MAGAZINE OPTION

For applicable turn-milling configurations, automatic tool magazine options are available.

Selected V Series configurations may use 10 or 12-tool ATC arrangements.

This can be useful where the machine is expected to perform several drilling or milling operations in addition to turning.


HIGH-SPEED FEED SYSTEM

• X-axis rapid traverse: 18 m/min
• Z-axis rapid traverse: 18 m/min

Although slightly slower than the smaller V6H, the V8H feed system is designed around the larger moving mass and heavier structural platform.

For production work, overall cycle time benefits come from the combination of:

• Rapid axis movement
• Fast turret indexing
• Efficient spindle response
• Reduced workpiece handling
• Vertical workholding


CHIP MANAGEMENT

Chip removal is particularly important on a vertical lathe because chips naturally fall toward the machine base.

The V Series incorporates a large chip-removal angle intended to reduce chip accumulation and improve chip evacuation.

This helps:

• Reduce chip build-up
• Improve coolant return
• Maintain cleaner machining conditions
• Reduce interruption during production
• Improve reliability during longer cycles

For cast iron, steel and other high-chip-volume applications, chip conveyor configuration should be reviewed as part of the quotation.


COMPACT RELATIVE TO CAPACITY

One of the strengths of the V Series is that substantial turning capacity is provided without moving immediately into a very large table-type vertical lathe platform.

The V8H has an approximate machine weight of 10.5 tonnes, yet provides:

• 1,000 mm maximum rotary diameter
• 850 mm maximum turning diameter
• 850 mm maximum turning height

This makes it a practical intermediate platform for workshops that require significantly more capacity than the V6H but do not yet need a 20–25 tonne VTC machine.


TYPICAL WORKPIECES

The V8H is particularly well suited to larger rotational components where diameter is high relative to length.

Typical examples include:

• Large bearing rings
• Large wheel hubs
• Brake components
• Gear blanks
• Large flanges
• Pulleys
• Sleeves
• Large bushes
• Pump housings
• Valve components
• Motor housings
• Gearbox housings
• Hydraulic components
• Large rotational castings
• Mining equipment components
• Industrial equipment components


TYPICAL INDUSTRIES

Potential industries include:

• Mining and resources
• Heavy vehicle
• Rail
• Bearing manufacturing
• Automotive
• New energy
• Pump and valve
• General engineering
• Agricultural equipment
• Industrial equipment
• Heavy maintenance

• Replacement-component manufacture


V8H VS HORIZONTAL CNC LATHE

A V8H should not automatically replace a horizontal CNC lathe.

A horizontal turning centre is generally better suited to:

• Long shafts
• Bar work
• Components requiring substantial tailstock support
• Long slender workpieces
• Bar-fed production

The V8H becomes more attractive when the workpiece is:

• Large in diameter
• Relatively short
• Disc-shaped
• Ring-shaped
• Flange-shaped
• Heavy
• Easier to support vertically
• Difficult to load safely into a conventional horizontal chuck

The choice should be based on workpiece geometry and process, not simply maximum diameter.


V8H VS V6H

The V6H and V8H share the same basic high-efficiency V Series architecture but target different workpiece sizes.

V6H

• Maximum rotary diameter: 700 mm
• Maximum turning diameter: 600 mm
• Maximum turning height: 650 mm
• Standard chuck: 15 inch
• Maximum spindle speed: 2,500 rpm
• X / Z travel: 330 / 653 mm
• Rapid traverse: 20 / 20 m/min
• Approximate machine weight: 7,500 kg

V8H

• Maximum rotary diameter: 1,000 mm
• Maximum turning diameter: 850 mm
• Maximum turning height: 850 mm
• Standard chuck: 21 inch
• Optional chuck: 24 / 32 inch
• Maximum spindle speed: 1,500 rpm
• X / Z travel: 480 / 850 mm
• Rapid traverse: 18 / 18 m/min
• Approximate machine weight: 10,500 kg

Choose V6H where:

• Components remain within 600 mm turning diameter
• Higher spindle speed is useful
• Floor space and capital cost are priorities

Choose V8H where:

• Workpiece diameter approaches 850 mm
• Larger chuck capacity is required
• Workpieces are heavier
• Greater turning height is needed
• Additional structural capacity is justified

Buying V8H for components comfortably handled by V6H adds cost and floor-space requirements without necessarily improving productivity.


V8H VS VTC10080

This is an important distinction.

The V8H and VTC10080 may appear close in nominal size, but they are fundamentally different machine platforms.

V8H

• Turret-type high-efficiency vertical lathe
• Maximum turning diameter: 850 mm
• Maximum turning height: 850 mm
• Standard 21 inch chuck
• Maximum spindle speed: 1,500 rpm
• Machine weight: approximately 10,500 kg
• Intended for relatively fast production turning

VTC10080

• Large table-type CNC vertical lathe
• 1,000 mm worktable
• Maximum rotary diameter: 1,400 mm
• Maximum turning diameter: 1,100 mm
• Maximum workpiece height: 800 mm
• Machine weight: approximately 23,000 kg
• Available in turning and turn-milling configurations

The V8H therefore fills an important gap.

It provides substantially more capacity than the V6H while remaining far more compact and production-oriented than the VTC10080.


BEST FIT

The V8H is a strong fit where the customer needs:

• 600–850 mm class turning diameter
• Large disc or ring component machining
• Heavy chucking capability
• Production-oriented vertical turning
• High machine rigidity
• Compact footprint relative to workpiece capacity
• Optional powered tooling
• Potential automation
• Faster cycling than a large table-type VTC


NOT THE BEST FIT

The V8H may not be the best choice for:

• Long shafts
• Long bar work
• Components needing conventional tailstock support
• Components significantly above 850 mm turning diameter
• Extremely heavy workpieces requiring a large worktable
• Very tall large-diameter components
• Complex five-axis machining
• Applications where a V6H already provides sufficient capacity

In these cases, MachineryPLUS can review horizontal turning centres, V6H, VTC Series or turn-milling alternatives.
