NEW SMTCL HTM40100h Horizontal Turn-Milling Centre

NEW SMTCL HTM40100h Horizontal Turn-Milling Centre

HIGH-PERFORMANCE TURN-MILLING CENTRE FOR COMPLEX COMPONENTS

The SMTCL HTM40100h is a high-performance horizontal turn-milling centre designed for complex components requiring turning, milling, drilling, boring and angular machining in a single setup.

Unlike a conventional CNC turning centre fitted with driven tools, the HTM40100h incorporates a dedicated high-speed milling spindle, B-axis milling head, C-axis turning spindle and automatic tool magazine.

This allows complex rotational and prismatic features to be machined without repeatedly transferring the workpiece between separate turning and machining centres.

For Australian manufacturers producing high-value, complex components, the main advantage is not simply additional machining capability — it is process consolidation.

Fewer setups can mean:

• Reduced workpiece handling

• Reduced accumulated setup error

• Improved positional relationship between turned and milled features

• Shorter overall manufacturing lead time

• Lower work-in-progress

• Better repeatability on complex components

• Greater flexibility for low-volume, high-value production

KEY MACHINING CAPACITY

• Maximum swing diameter: 600 mm

• Maximum turning diameter: 400 mm

• Maximum machining length: 1,000 mm

• X-axis travel: 520 mm

• Y-axis travel: ±100 mm

• Z-axis travel: 1,400 mm

• B-axis travel: ±120°

• Tailstock travel: 1,000 mm

• Tailstock quill travel: 150 mm

TURNING SPINDLE

• Maximum spindle speed: 4,000 rpm

• Rated main motor power: 22 kW

• Rated spindle torque: 150 Nm

• Spindle nose: A2-6

The HTM40100h uses a high-speed built-in electric turning spindle developed for applications requiring speed, accuracy, low noise and good dynamic response.

Its spindle configuration makes the machine particularly suitable for components requiring both accurate turning and subsequent high-speed milling operations.

DEDICATED MILLING SPINDLE

This is one of the key differences between the HTM40100h and a conventional driven-tool turning centre.

• Maximum milling spindle speed: 12,000 rpm

• Rated milling spindle power: 35 kW

• Rated milling spindle torque: 83 Nm

• Tool interface: CAPTO C5

• Automatic tool magazine: 32 tools

The independent milling spindle provides substantially greater machining flexibility than conventional turret-mounted driven tooling.

It allows the machine to perform genuine milling-centre-type operations while the workpiece remains located in the turning spindle.

B-AXIS MILLING HEAD

• B-axis swivel range: ±120°

• B-axis torque: 632 Nm

The B-axis allows the milling spindle to approach the component from multiple angles, significantly expanding the machining envelope.

This enables:

• Angular drilling

• Angular milling

• Side-face machining

• Contouring

• Complex hole patterns

• Multi-face machining

• Features that would otherwise require additional setups or dedicated fixtures

The B-axis is driven by a torque motor, reducing the mechanical transmission chain and supporting high positioning accuracy and dynamic performance.

C-AXIS TURNING SPINDLE

The turning spindle can also function as a precision C-axis for milling operations.

This allows rotational positioning of the workpiece for features such as:

• Bolt-hole patterns

• Keyways

• Flats

• Slots

• Radial holes

• Circumferential milling

• Angular features

• Complex multi-axis machining

Combined with the Y-axis and B-axis milling head, the HTM40100h provides a highly flexible platform for complex component manufacture.

FIVE-AXIS TURN-MILLING CAPABILITY

The HTM40100h combines:

• X axis

• Y axis

• Z axis

• B-axis milling head

• C-axis turning spindle

This architecture provides five-axis machining capability for suitable applications.

The major benefit is the ability to machine complex turned and milled features while maintaining the workpiece datum from a single clamping wherever the process allows.

HIGH-RIGIDITY MACHINE STRUCTURE

SMTCL has designed the HTM platform around machining stability rather than simply adding milling capability to a conventional CNC lathe.

Structural features include:

• 45° integral inclined machine bed

• Internal rib-reinforced casting structure

• Three-guide-rail support arrangement

• Heavy-load roller linear guideways

• Wide-span saddle guideway layout

• Low-centre-of-gravity structural arrangement

• Steel hardened guideway support for the tailstock

The three-guide-rail support layout helps improve component support stiffness and machining stability, particularly where combined turning and milling forces are involved.

ACCURACY AND MOTION CONTROL

The HTM Series incorporates design features intended to maintain accuracy during complex multi-axis machining.

These include:

• Precision ball-screw feed systems

• Bearing arrangements designed to reduce thermal influence

• Direct-drive B-axis torque motor

• High-accuracy B-axis encoder

• High-accuracy angular feedback for rotary positioning

• Heavy-load roller guideways

• High-rigidity machine structure

The objective is stable positioning and repeatability during combined turning and multi-axis milling operations.

HIGH-PRODUCTIVITY MACHINING

Rapid traverse is up to:

• X axis: 30 m/min

• Y axis: 30 m/min

• Z axis: 30 m/min

Higher-speed configurations may be available depending on final machine specification.

Combined with the automatic 32-tool magazine and dedicated milling spindle, the HTM40100h can perform multiple operations sequentially without manually transferring the component between machines.

WHY HTM INSTEAD OF A CONVENTIONAL CNC TURNING CENTRE?

A conventional CNC turning centre remains the more economical solution when the majority of the work is turning.

A turning centre with driven tooling can also perform relatively simple drilling and milling operations.

The HTM40100h becomes particularly relevant when the component requires substantially more milling capability.

Consider the HTM40100h where the workpiece requires:

• Significant turning and milling on the same component

• High-speed milling

• Y-axis machining

• Angular machining

• Multiple machined faces

• Complex drilling patterns

• Accurate relationship between turned and milled features

• Reduced re-clamping

• Reduced movement between separate machines

• More complete machining in one setup

For relatively simple turned components, an HTM may be more machine than the application requires.

MachineryPLUS prefers to match the machine to the actual component rather than recommend additional complexity that does not create value.

HTM40100h POSITION WITHIN THE SMTCL RANGE

The HTM40100h is the compact model within SMTCL's broader HTM horizontal turn-milling family.

It provides:

• 400 mm maximum turning diameter

• 1,000 mm machining length

• High-speed electric turning spindle

• 12,000 rpm dedicated milling spindle
