SMTCL HTC40m Series Horizontal Turning Centre with Driven Tooling
The SMTCL HTC40m Series is a horizontal turning centre platform with driven tooling, designed for shaft and disc-type components requiring turning plus drilling, milling or tapping in one setup.
Compared with a conventional two-axis HTC40 lathe, the HTC40m adds a 12-station horizontal power turret and driven-tool capability, allowing secondary machining operations to be completed without moving the component to a separate machining centre.
The Series is available in H(Q)m and Sm configurations with turning-length classes from approximately 450 mm to 1450 mm.
The HTC40m is particularly suited to workshops producing components with turned diameters, cross holes, flats, keyways, bolt patterns or tapped features where reducing multiple setups can improve cycle time, accuracy and work-in-progress control.

Driven-Tooling Capability
The defining feature of the HTC40m Series is the horizontal power turret.
Unlike the standard HTC40 turning platform, the HTC40m can support driven tools for operations such as:
• Axial drilling
• Radial drilling
• Light milling
• Flats
• Keyways
• Cross holes
• Bolt-hole patterns
• Tapping
• Chamfering
• Secondary finishing operations
This can reduce the need to transfer the workpiece to a separate machining centre after turning.
12-Station Horizontal Power Turret
The HTC40m Series uses a 12-station horizontal power turret.
Depending on configuration:
• HTC40H(Q)m may use BMT55 or BMT45
• HTC40Sm uses BMT55
The power turret provides:
• More tool stations than a standard 8-station HTC40 turret
• Driven-tool capability
• Greater process flexibility
• Reduced setup changes
• Improved suitability for mixed turning and secondary machining
Representative Driven-Tool Capacity
The current supplier-confirmed HTC40m specification lists:
• Maximum drilling capacity: approximately Ø16 mm
• Maximum milling capacity: approximately Ø14 mm
• Maximum tapping capacity: approximately M12
These values represent the current listed series capability and should be confirmed against the selected turret, toolholder, driven-tool unit, material and machining process before quotation.
C-Axis and Final Driven-Tool Configuration
Driven tooling normally requires the spindle and control system to support the required indexing or C-axis operation.
Final HTC40m configuration should therefore confirm:
• C-axis capability
• Driven-tool speed
• Driven-tool power
• Driven-tool torque
• Turret interface
• Axial and radial driven-tool holders
• CNC control functions
• Interpolation requirements
These items should be matched to the actual component drawing rather than assumed from the model designation alone.
H(Q)m vs Sm Positioning
HTC40H(Q)m
Positioned for:
• General-purpose or higher-efficiency turning
• Smaller bar work
• Faster general production
• Components requiring moderate driven-tool operations
Main characteristics:
• 50 mm bar capacity
• 8-inch chuck
• 4000 rpm spindle
• 350 mm maximum turning diameter
• 12-station power turret
HTC40Sm
Positioned for:
• Stronger turning applications
• Larger bar capacity
• Larger chucking requirements
• Heavier turned-milled components
Main characteristics:
• 65 mm bar capacity
• 10-inch chuck
• Up to 400 mm turning diameter on the 1500 class
• BMT55 power turret

Why Choose HTC40m Instead of Standard HTC40?
Choose the standard HTC40 when the component requires mainly:
• External turning
• Internal boring
• Grooving
• Threading
• Drilling on the spindle centreline
and secondary milling operations can be completed economically elsewhere.
Choose HTC40m when the component also requires:
• Cross drilling
• Off-centre drilling
• Flats
• Keyways
• Milled features
• Tapped holes
• Bolt patterns
• Additional operations that would otherwise require a second machine setup
The main benefit of HTC40m is therefore not simply a more complex turret.
It is the ability to reduce process transfers and complete more of the component in one clamping.
Single-Setup Manufacturing
Completing turning and secondary machining in one setup can provide several practical advantages:
• Reduced workpiece handling
• Reduced setup time
• Fewer fixtures
• Improved feature relationship between turned and milled surfaces
• Reduced work-in-progress
• Shorter production lead time
• Lower risk of setup errors
• Easier process control
This is particularly valuable for small and medium production batches where secondary operations would otherwise require repeated setup on another machine.
Typical Applications
The HTC40m Series is well suited to:
• General engineering
• Automotive components
• Hydraulic components
• Pump and valve components
• Motor components
• Drive-system components
• Mining support components

• Flanges
• Multi-feature turned components
• Small to medium batch production
Typical Workpieces
Typical HTC40m workpieces may include:
• Gear shafts with keyways
• Motor shafts with flats

• Valve components
• Couplings
• Spacers
• Bearing-related parts
• General turned-milled components
Why Consider the HTC40m Series?

• Larger turning diameter is required
• Longer parts are common
• Larger 12-inch chucking is required
• Higher-capacity turning plus milling is needed
HTC m-Series Positioning
The “m” designation identifies HTC configurations equipped for turning plus driven-tool operations.
Current MachineryPLUS data includes:
• HTC30m
• HTC40m
• HTC50m
The m-Series is particularly relevant where the component requires conventional turning together with moderate drilling, milling or tapping operations.
HTC30m
Compact driven-tool platform.
Best suited for:
• Smaller components
• 250 mm-class turning
• Short shafts and sleeves
• BMT45 tooling
HTC40m
Mid-size driven-tool platform.
Best suited for:
• Medium shafts and disc components
• 350–400 mm-class turning
• 50–65 mm bar capacity
• Longer bed-length choices

HTC50m
Larger driven-tool platform.
Best suited for:

Not the Best Fit When
The HTC40m may not be the best choice when:
• The part only requires simple two-axis turning

• Large Y-axis travel is mandatory
• Extensive contour milling is required
• A sub-spindle is essential
• Complex five-axis-style turn-mill machining is required
For these applications, a standard HTC40, larger HTC50m or an HTM turn-mill machining centre may be more appropriate.
