NEW SMTCL HTM80 Series Horizontal Turn-Milling Centre

NEW SMTCL HTM80 Series Horizontal Turn-Milling Centre

LARGE-FORMAT HORIZONTAL TURN-MILLING CENTRE FOR LONG, HEAVY AND COMPLEX COMPONENTS

The SMTCL HTM80 Series is a large-format horizontal turn-milling centre developed for high-value components requiring heavy-duty turning, milling, drilling, boring and angular machining on the same machine.

With a maximum machining diameter of 800 mm and available machining lengths from 1,500 mm through to 6,000 mm, the HTM80 is positioned above the HTM63 Series for larger-diameter, longer and heavier workpieces.

The machine combines a high-torque mechanical turning spindle, dedicated milling spindle, B-axis milling head, C-axis workpiece positioning and automatic tool magazine.

For suitable components, this allows multiple turning and milling operations to be completed without repeatedly moving the workpiece between separate CNC lathes, machining centres and drilling machines.

The result can be significantly reduced handling, fewer datum changes and better control of the relationship between machined features.

AVAILABLE HTM80 CONFIGURATIONS

The HTM80 Series is available with multiple machining lengths:

• 1,500 mm

• 3,000 mm

• 5,000 mm

• 6,000 mm

This makes the platform particularly suitable for manufacturers working with long shafts and large rotational components where conventional turn-milling centres may not provide sufficient length capacity.

KEY MACHINING CAPACITY

• Maximum body swing: 1,000 mm

• Maximum machining diameter: 800 mm

• Available machining lengths: 1,500 / 3,000 / 5,000 / 6,000 mm

• X-axis travel: -30 to +720 mm

• Y-axis travel: -200 to +300 mm

• Z-axis travel: 1,700 / 3,200 / 5,200 / 6,200 mm

• B-axis travel: ±100°

The combination of large diameter capacity, substantial Y-axis movement and long Z-axis configurations gives the HTM80 considerably greater application range than a conventional large CNC turning centre.

HEAVY-DUTY TURNING SPINDLE

The HTM80 uses a mechanically driven turning spindle developed for high-torque machining.

• Spindle nose: A2-15

• Spindle bore: 100 mm

• Maximum spindle speed: 1,600 rpm

• Turning spindle motor: 51 kW

• Rated spindle torque: 2,000 Nm

• Standard chuck diameter: 500 mm

The main transmission uses a motor, two-speed reduction gearbox and belt-drive arrangement.

Compared with a high-speed electric spindle, this configuration prioritises torque, rigidity and load capacity for larger workpieces and heavier cutting.

Large-diameter spindle bearings further improve spindle rigidity and load-bearing capability.

A thermally symmetrical spindle structure is used to reduce the influence of thermal deformation during machining.

DEDICATED MILLING SPINDLE

The HTM80 is not simply a large CNC lathe fitted with driven tools.

It incorporates a dedicated milling spindle designed for substantial milling, drilling and multi-axis machining operations.

• Milling spindle interface: HSK-T100

• Maximum milling spindle speed: 4,000 rpm

• Rated milling spindle power: 30 kW

• Rated milling spindle torque: 315 Nm

• Automatic tool magazine: 30 or 60 tools

The HSK-T100 interface and dedicated milling spindle provide a substantially more capable platform for milling operations than conventional turret-driven tooling.

This is particularly valuable where large turned components also require extensive keyways, flats, pockets, drilling patterns, angular features or multi-face machining.

B-AXIS MILLING HEAD

• B-axis swivel range: ±100°

The B-axis allows the milling spindle to approach the workpiece from different angles.

This expands the range of operations that can be completed while maintaining the same primary workpiece setup.

Typical B-axis operations may include:

• Angular drilling

• Angular boring

• Side-face milling

• Inclined surfaces

• Complex hole patterns

• Multi-face machining

• Contouring

• Features located at different angular orientations

The B-axis uses direct torque-motor drive technology to minimise the mechanical transmission chain and support accurate positioning and dynamic response.

C-AXIS TURNING SPINDLE POSITIONING

During milling operations, the main turning spindle can be used as a controlled rotary axis.

This allows the workpiece to be accurately indexed or continuously controlled for operations such as:

• Radial drilling

• Circumferential hole patterns

• Keyways

• Flats

• Slots

• Cross holes

• Angular features

• Circumferential milling

• Complex rotational geometry

Combined with X, Y, Z and B-axis movement, this creates a highly flexible turn-milling machining platform.

MULTI-AXIS TURN-MILLING CAPABILITY

The HTM80 integrates:

• X axis

• Y axis

• Z axis

• B-axis milling head

• C-axis turning spindle

This architecture enables complex multi-axis turn-milling processes on suitable components.

The key advantage is not simply the number of axes.

The real advantage is the possibility of maintaining a common datum while turning and milling complex features on the same machine.

WHY PROCESS CONSOLIDATION MATTERS

For large precision components, moving the workpiece between machines can become a major part of manufacturing cost and risk.

A traditional process may involve:

1. Rough turning on a CNC lathe

2. Removing the component

3. Moving it to a machining centre or boring machine

4. Re-establishing the datum

5. Milling and drilling

6. Returning it to another machine for additional turning

7. Further inspection and correction

For large or long components, every transfer may require lifting equipment, additional setup time and another opportunity for datum error.

The HTM80 can allow many of these operations to remain within one machining platform.

Potential benefits include:

• Fewer setups

• Reduced crane and handling requirements

• Reduced workpiece movement

• Reduced accumulated setup error

• Better positional relationship between turned and milled features

• Reduced work-in-progress

• Shorter manufacturing lead time

• Improved repeatability

• Reduced fixture requirements

• Better utilisation of skilled operators

HIGH-RIGIDITY MACHINE STRUCTURE

The HTM Series uses a structure developed specifically for combined turning and milling loads.

Key structural features include:

• 45° integral inclined cast bed

• Internal rib-reinforced casting structure

• Three-guide-rail auxiliary support design

• Heavy-load roller linear guideways

• Wide-span saddle support

• Low-centre-of-gravity guideway arrangement

• Steel hardened guideways for the tailstock

The three-guide-rail support arrangement improves structural support and machining stability.

Heavy-load roller guideways provide high load capacity while maintaining positioning performance.

The wide-span, low-centre-of-gravity saddle arrangement further improves rigidity during combined turning and milling.

ACCURACY AND AXIS CONTROL

The HTM Series incorporates several design features intended to maintain accuracy during complex machining.

These include:

• Precision ball-screw feed systems

• Bearing arrangements designed to reduce ball-screw thermal influence

• Direct-drive B-axis torque motor

• High-accuracy B-axis encoder

• High-accuracy rotary-axis feedback

• Controlled C-axis spindle positioning

• Heavy-load roller guideways

• High-rigidity integral machine structure

For complex turn-milling applications, these features are important because errors between turning and milling operations can affect finished-component geometry.

LONG-WORKPIECE CAPABILITY

One of the strongest reasons to consider the HTM80 Series is its available machining length.

With configurations extending to 6,000 mm, the machine can address long components that are outside the practical range of many conventional turn-milling centres.

Potential long-workpiece applications include:

• Large shafts

• Drive shafts

• Rotor shafts

• Rolls

• Axles

• Hydraulic components

• Long rotating equipment components

• Mining equipment components

• Energy-sector shafts

• Special-purpose industrial components

Long parts introduce additional requirements for support, workholding, tailstock configuration, vibration control and machining strategy.

For this reason, MachineryPLUS recommends reviewing the actual component drawing before selecting an HTM80 configuration.

TYPICAL WORKPIECES

The HTM80 is particularly suited to high-value components combining substantial turning with secondary milling or drilling requirements.

Typical examples may include:

• Large shafts

• Rotor components

• Drive components

• Spindles

• Rolls

• Heavy-duty axles

• Large hydraulic components

• Pump components

• Valve components

• Gearbox components

• Rotating equipment components

• Mining equipment components

• Energy-sector components

• Large flanges

• Complex cylindrical components with milled features

• Long components requiring cross holes or angular machining

TYPICAL INDUSTRIES

Potential applications include:

• Mining and resources

• Oil and gas

• Energy

• Power generation

• Heavy engineering

• Pump and valve manufacturing

• Rotating equipment manufacture and repair

• Transport and rail

• Defence manufacturing

• General engineering

• Large-component contract machining

• Maintenance and replacement-part manufacture

WHY HTM80 INSTEAD OF A LARGE CNC LATHE?

A large CNC lathe remains the better-value choice where the workpiece requires predominantly turning.

Even a CNC turning centre with driven tooling may be sufficient where milling requirements are relatively simple.

The HTM80 becomes more relevant when milling is a significant part of the manufacturing process.

Consider HTM80 where the component requires:

• Heavy turning plus substantial milling

• Long machining length

• Large workpiece diameter

• Y-axis machining

• B-axis angular machining

• Multiple milled faces

• Cross drilling

• Angular holes

• Deep or complex drilling patterns

• Accurate relationship between turned and milled features

• Reduced re-clamping

• Reduced transfer between machines

• Multiple operations completed from one primary setup

If the component is primarily a turning job with only limited drilling or simple keyways, a less complex turning-centre solution may provide better value.

MachineryPLUS prefers to select the machine around the process rather than recommend additional machine capability that the customer will not use.

HTM80 VS HTM63

Both HTM63 and HTM80 are large horizontal turn-milling platforms, but they address different component sizes and cutting requirements.

HTM63 Series

• Maximum machining diameter: 630 mm

• Maximum machining length: 2,000 / 3,000 mm

• Turning spindle: 37 kW

• Rated turning torque: 1,400 Nm

• Milling spindle: 17 kW

• Milling torque: 270 Nm

• HSK-A63 / CAPTO C6 tooling

HTM80 Series

• Maximum machining diameter: 800 mm

• Maximum machining length: up to 6,000 mm

• Turning spindle: 51 kW

• Rated turning torque: 2,000 Nm

• Milling spindle: 30 kW

• Milling torque: 315 Nm

• HSK-T100 tooling

The HTM80 is therefore the better fit where the component is larger, longer, heavier or requires greater turning and milling capacity.

The HTM63 may remain the more economical solution where the workpiece falls comfortably within its capacity.
