NEW SMTCL HTC63m Horizontal Turning Centre

SMTCL HTC63m Series High-Capacity Horizontal Turning Centre with Driven Tooling

The SMTCL HTC63m Series is a high-capacity horizontal turning centre platform designed for larger shaft, disc and engineering components requiring turning together with milling, drilling and other secondary machining operations in one setup.

Available in Qm, Hm and Sm configurations, the HTC63m Series provides a choice between general-purpose multi-process machining, high-efficiency production and heavy-cutting capability.

Compared with the smaller HTC50m platform, the HTC63m provides a substantially larger machining envelope and greater capacity for heavier engineering workpieces.

The Series is equipped with C-axis capability and a horizontal 12-station power tool carriage, allowing customers to complete more machining processes in one clamping and reduce transfers between separate turning and machining centres.

The HTC63m is particularly suitable for engineering machinery, automotive components, pumps and motors, valves, energy-sector components, large shafts, flanges and other complex rotational parts containing drilled, milled or indexed features.

• 1450 mm

• 1950 mm

• 2950 mm maximum turning length

Model designation and actual usable turning length should not be confused.

For example, a nominal 1500-class machine may provide a slightly lower actual maximum turning length depending on the selected Hm or Sm configuration.


Turning, Milling and Drilling in One Setup

The defining advantage of the HTC63m is the ability to perform conventional turning together with secondary machining operations.

Typical machining processes can include:

• External turning

• Internal boring

• Facing

• Grooving

• Threading

• Axial drilling

• Radial drilling

• Cross drilling

• Milling flats

• Milling slots

• Keyways

• Indexed features

• Bolt-hole patterns

• Secondary finishing operations

This can substantially reduce the need to move a large workpiece between separate machines.


High-Accuracy C-Axis

The HTC-m platform uses a high-accuracy C-axis system.

The manufacturer identifies:

• High-accuracy built-in spindle encoder

• Accurate angular positioning

• C-axis brake device

• Driven-tool integration

This allows the spindle to act as a controlled rotary axis during milling and drilling operations.

Typical C-axis applications include:

• Cross holes

• Angular hole patterns

• Bolt circles

• Flats

• Keyways

• Indexed slots

• Multi-position milling


12-Station Power Tool Carriage

The HTC63m uses a horizontal 12-station power tool carriage.

The power turret provides:

• Static turning-tool capability

• Driven-tool capability

• Multiple tools available in one setup

• Reduced manual tool changes

• Efficient process sequencing

• High-rigidity tool support

The exact BMT interface and driven-tool package should be confirmed for the selected HTC63Qm, HTC63Hm or HTC63Sm before quotation.


High-Efficiency Feed System

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

The manufacturer describes this arrangement as reducing intermediate transmission links and providing low-clearance transmission.

The feed-system design incorporates:

• Precision ballscrews

• Linear rolling guideways

• Direct servo drive

• High dynamic response

• High rigidity

• High positioning consistency

Applicable HTC-m configurations can achieve rapid traverse speeds up to approximately 30 m/min.

Final X/Z rapid traverse should be confirmed against the selected HTC63m machine.


Optional Y-Axis

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

When combined with:

• C-axis

• BMT power turret

• Driven tooling

the Y-axis allows more complex machining in one clamping.

Potential Y-axis applications include:

• Off-centre drilling

• Off-centre milling

• Slots

• Offset flats

• Complex milled features

• Multi-sequence integrated machining

Y-axis is an optional configuration and should not be assumed to be standard on every HTC63m.


High-Accuracy Ballscrew System

The HTC-m Series uses high-accuracy pre-tensioned ballscrews.

The manufacturer identifies:

• C3-grade precision ballscrews

• Double-fixed support structure

• Pre-tensioning

• Error-compensation technology

Pre-tensioning helps offset thermal growth and supports:

• Stable feed accuracy

• Better repeatability

• Reduced thermal influence

• Consistent production machining


High-Rigidity Structure

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

Structural features identified by the manufacturer include:

• Integral high-rigidity casting

• U-shaped internal rib structure

• Large-span spindle unit

• Anti-bending saddle design

• Optimised guideway span

• Finite-element structural optimisation

These features help improve:

• Cutting rigidity

• Vibration resistance

• Heavy-cutting stability

• Surface quality

• Long-term machining consistency


High-Rigidity Spindle Support

The HTC-m platform uses a long-span sleeve-type spindle structure.

The spindle support incorporates:

• Double-row cylindrical roller bearings

• Angular-contact ball bearings

• Composite bearing support arrangement

The objective is to provide:

• High spindle rigidity

• Strong torque transmission

• Stable heavy cutting

• Improved machining consistency


Optional Servo Tailstock

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

The servo tailstock allows:

• Controlled approach speed

• Adjustable support force

• Position feedback

• Faster workpiece changeover

• Reduced impact when contacting the workpiece

This is particularly useful for longer shaft-type components.

Final tailstock specification should be confirmed according to workpiece length, weight and machining forces.


Accuracy and Process Control

The HTC-m catalogue identifies several measures used to support production accuracy:

• C3-grade ballscrews

• Precision C-axis encoder

• Feed-axis pre-tensioning

• Error compensation

• Quantified assembly procedures

• Laser-interferometer verification

• Strict functional-component inspection

Manufacturer batch testing reports:

• CMK 2.0 or above under stated test conditions

• Approximately IT6-level batch machining capability

• Repeated machining accuracy error up to approximately 0.003 mm in the referenced test

These are manufacturer test results under specified conditions and should not be treated as guaranteed finished-part accuracy for every workpiece, material or production environment.


Single-Setup Manufacturing

For large workpieces, the benefits of reducing secondary setups can be significant.

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

• Workpiece handling

• Crane movements

• Re-clamping

• Fixture requirements

• Secondary-machine setup

• Work-in-progress

• Accumulated setup error

• Production lead time

This is particularly valuable on HTC63-size components because larger workpieces are more difficult and time-consuming to transfer between machines.

The HTC63m Series is well suited to:

• Engineering machinery

• Automotive components

• Energy-sector components

• Pump components

• Motor components

• Valve components
