NEW SMTCL HTC80m Horizontal Turning Centre

SMTCL HTC80m Series Heavy-Duty Horizontal Turning Centre with Driven Tooling

The SMTCL HTC80m Series is a heavy-duty horizontal turning centre platform designed for large shaft and disc-type components requiring turning together with milling, drilling and other secondary machining operations in one setup.

Available in HTC80Hm and HTC80Sm configurations, the Series combines large workpiece capacity, high-rigidity construction, C-axis capability and driven tooling for demanding industrial production.

The HTC80Hm is the high-efficiency configuration, while the HTC80Sm is the heavy-cutting configuration with increased spindle power and stronger machining capability.

The HTC80m is particularly suited to large shafts, heavy discs, valve components, engineering machinery, energy-sector parts, castings, forgings and other large rotational components containing drilled, milled or indexed features.

By combining turning and driven-tool operations in one clamping, the HTC80m can reduce secondary-machine setups, workpiece handling and accumulated setup error.

• Maximum swing over saddle: approximately 805 mm

Actual turning capacity varies according to the selected Hm or Sm configuration and should be confirmed against the exact workpiece geometry before quotation.


Turning, Milling and Drilling in One Setup

The defining feature of the HTC80m Series is the ability to combine large-capacity turning with driven-tool operations.

Typical machining processes may include:

• External turning

• Internal boring

• Face turning

• Grooving

• Threading

• Axial drilling

• Radial drilling

• Cross drilling

• Milling flats

• Keyways

• Slots

• Indexed milling

• Bolt-hole patterns

• Secondary finishing operations

For large workpieces, reducing the need to move components between machines can provide significant production advantages.


C-Axis Capability

The HTC-m platform is equipped with C-axis capability.

The manufacturer identifies the HTC-m Series as combining:

• C-axis spindle control

• Power tool carriage

• Driven tooling

• Turning

• Milling

• Drilling

This allows indexed secondary operations to be completed on the turning centre.

Typical C-axis applications include:

• Cross holes

• Bolt circles

• Angular hole patterns

• Flats

• Keyways

• Indexed slots

• Multi-position milling


Power Tool Carriage

The HTC80m uses a horizontal power-tool carriage as part of the HTC-m platform.

The power-tool system supports:

• Static turning tools

• Driven tools

• Multi-operation machining

• Reduced secondary setup

• Improved process integration

• Better production flexibility

The exact turret interface, driven-tool speed, driven-tool power and tooling package should be confirmed for the selected HTC80Hm or HTC80Sm configuration.


High-Efficiency Hm Platform

The manufacturer defines Hm as the high-efficiency HTC-m product family.

The Hm platform is intended to provide:

• High-efficiency multi-process machining

• High machining accuracy

• Excellent stability

• Strong production capability

• Efficient turning, milling and drilling integration

Typical target industries include:

• Automotive

• Pump and motor manufacturing

• Engineering machinery

• General production


Heavy-Cutting Sm Platform

The manufacturer defines Sm as the heavy-cutting HTC-m product family.

The Sm platform places greater emphasis on:

• Large torque

• Strong rigidity

• Heavy material removal

• Multi-process machining

• Large workpiece capability

Typical target industries include:

• Automotive heavy components

• Energy

• Valves

• Engineering machinery

• Heavy industrial manufacturing


High-Rigidity Machine Structure

The HTC-m Series uses high-quality cast iron for the machine body and other key structural components.

The manufacturer highlights:

• High-quality cast iron body

• Large-span spindle unit

• Circular curved anti-bending saddle

• Tailstock with small-spindle structure

These structural features are intended to improve:

• Machine rigidity

• Cutting stability

• Vibration resistance

• Heavy-duty machining performance

• Long-term accuracy retention


High-Efficiency Feed System

The HTC-m platform uses servo motors coupled to the ballscrews through couplings.

This reduces intermediate transmission components and supports:

• Low-clearance transmission

• High dynamic response

• High axis rigidity

• Stable positioning

• Improved cycle efficiency

The manufacturer lists fast axis movement up to approximately 30 m/min on applicable HTC-m configurations.

Final rapid traverse should be confirmed for the selected HTC80Hm or HTC80Sm machine.


Linear Rolling Guideways

The HTC-m platform uses linear rolling guideways on the X and Z axes.

The manufacturer identifies this arrangement as providing:

• High rigidity

• Good dynamic performance

• High accuracy

• Higher running speed

• Improved production efficiency

Final guideway and feed-system details should be confirmed against the selected HTC80m configuration.


Optional Y-Axis

The HTC-m platform can be configured with an optional Y-axis.

When combined with:

• C-axis

• Power turret

• Driven tooling

the Y-axis expands the machining capability for more complex features.

Typical Y-axis applications include:

• Off-centre drilling

• Off-centre milling

• Slots

• Offset flats

• Complex secondary machining

• Multi-sequence integrated machining

Y-axis is optional and should not be assumed to be standard on every HTC80m.


High-Accuracy Feed Technology

The HTC-m platform incorporates:

• High-accuracy pre-tensioned ballscrews

• Error-compensation technology

• Quantified process standards

• Strict inspection standards

These measures are intended to improve:

• Positioning consistency

• Repeatability

• Thermal stability

• Long-term production accuracy


Optional Servo Tailstock

The HTC-m platform can be configured with a split servo tailstock.

A servo-driven tailstock can provide:

• Controlled tailstock movement

• Adjustable support force

• Position feedback

• Faster workpiece changeover

• Reduced impact during workpiece support

This is particularly useful for large and long shaft components.

Final tailstock selection should be based on:

• Workpiece length

• Workpiece weight

• Cutting load

• Steady-rest requirement

• Automation requirement


Optional Internal-Coolant Tooling

The manufacturer also lists internal-coolant driven-tool holders.

Internal coolant can help improve:

• Hole machining

• Chip evacuation

• Tool cooling

• Surface quality

• Process stability

This is particularly useful for deeper drilling and internal machining operations.


Single-Setup Manufacturing

For HTC80-size components, reducing workpiece transfers can be especially valuable because the workpieces may be large and difficult to handle.

Completing turning and driven-tool operations in one clamping can help reduce:

• Crane movements

• Re-clamping

• Secondary-machine setup

• Fixture requirements

• Work-in-progress

• Accumulated setup error

• Production lead time

• Handling risk

This is one of the most important reasons to select HTC80m instead of a conventional large two-axis turning centre.
