NEW SMTCL HTC40/500 Slant Bed CNC Lathe

SMTCL HTC40/500 Slant Bed CNC Lathe

The SMTCL HTC40/500 is a compact slant bed CNC lathe designed for productive turning of shafts, sleeves, bushes, flanges and other small to medium rotational components.

With a maximum turning diameter of 380 mm and a maximum turning length of 500 mm, the HTC40/500 provides a practical production platform for workshops requiring greater rigidity, faster cycle performance and improved chip control compared with a conventional flat bed CNC lathe.

The machine combines an A2-8 spindle, 80 mm spindle bore, 50 mm bar capacity, 8-inch chuck, 4000 rpm spindle speed and 30 m/min X/Z rapid traverse in a compact workshop footprint.

It is particularly suited to general engineering, automotive components, hydraulic parts, maintenance production and repeat machining where workpieces comfortably fit within the 500 mm turning-length class.

Compact Slant Bed Production Platform

The HTC40/500 is designed as a compact production-oriented CNC turning centre rather than a long-bed general-purpose lathe.

The slant bed structure provides practical advantages for:

• Chip evacuation

• Turret access

• Production stability

• Operator access

• Enclosure integration

• Automated loading and unloading

This makes the machine particularly suitable for workshops moving from manual or flat bed CNC turning into more repeatable production machining.


Production-Focused Spindle Package

The HTC40/500 uses an A2-8 spindle configuration with:

• 80 mm spindle bore

• 50 mm bar capacity

• 8-inch chuck

• Maximum spindle speed of 4000 rpm

• 11 / 15 kW main motor

This spindle package provides a practical balance of speed, torque and bar capacity for small to medium shaft and disc-type components.

Typical workpieces include:

• Shafts

• Gear shafts

• Motor shafts

• Drive shafts

• Sleeves

• Bushes

• Flanges

• Valve components

• Spacer components

• Short chucking work


Fast X/Z Axis Movement

The HTC40/500 provides 30 m/min rapid traverse on both X and Z axes.

This helps reduce non-cutting time during:

• Repeated production cycles

• Shoulder turning

• Grooving

• Drilling

• Boring

• Threading

• Multi-diameter shaft machining

The 200 mm X-axis travel and 560 mm Z-axis travel provide sufficient axis movement for the machine’s 380 mm turning diameter and 500 mm turning-length class.


8-Station Servo Turret

The standard HTC40/500 configuration uses a horizontal 8-station servo turret.

The servo turret helps support:

• Faster tool indexing

• Repeatable tool positioning

• Reduced cycle time

• Multi-operation turning

• Small to medium batch production

Nearby tool selection is supported, allowing the control system to reduce unnecessary turret rotation during automatic cycles.


Hydraulic Tailstock

The HTC40/500 uses a hydraulic tailstock with:

• 450 mm tailstock travel

• MT5 taper

The hydraulic tailstock provides support for shaft-type workpieces where centre support is required.

It is particularly useful for:

• Longer shafts

• Slender components

• Components requiring improved turning stability

• Repeated shaft production


Compact Workshop Footprint

The HTC40/500 has an approximate machine size of:

2750 × 1890 × 1900 mm

and an approximate net weight of:

4200 kg

This provides useful production turning capacity without requiring the floor space of a longer-bed or larger-capacity machine.

The compact footprint can be particularly attractive for:

• General engineering workshops

• Smaller production shops

• Multi-machine cells

• Workshops replacing older manual lathes

• Customers planning future automation


Automation Capability

How to Choose Between Q, H and S

Choose the Q configuration when general production capability, speed and value are the main priorities.

Choose the H configuration when higher productivity, automation capability and production efficiency are more important.

Choose the S configuration when larger bar capacity, stronger chucking and heavier cutting capability are required.

The final machine should always be selected according to the actual workpiece rather than simply by series name.


Standard Configuration

Typical HTC40H(Q)/500 configuration includes:

• Sleeve-type spindle

• Hollow hydraulic chuck cylinder

• 8-inch chuck

• Hydraulic tailstock

• Horizontal 8-station servo turret

Control system depends on the selected series and final configuration.

The current product material lists:

• FANUC 0i-TF Plus for H Series standard catalogue configuration

• GSK 988TA for Q Series standard catalogue configuration


Available Options

Available options may include:

• Siemens control system

• Tool setting gauge

• 12-station servo turret where applicable

• Tool damage detection

• Workpiece measurement

• Power tool turret

• Oil mist collector

• Rear chip removal unit

• Pneumatic door

Final availability depends on the selected HTC40 configuration.


Not the Best Fit When

The HTC40/500 may not be the best choice when:

• Y-axis machining is required

• Sub-spindle machining is required

• Complex turn-mill work is the main application

For these applications, a longer HTC configuration, HTC40S, larger HTC model or HTM turn-mill platform may be more appropriate.


Machine Selection and Configuration

Final HTC40/500 configuration should be selected according to the actual workpiece and production process.

Please provide:

• Maximum workpiece diameter

• Maximum workpiece length

• Workpiece weight

• Material

• Bar diameter if bar feeding is required

• Drawing where available

• Required machining operations

• Required tolerances

• Surface finish requirements

• Expected batch quantity

• Preferred CNC control

• Chuck requirement

• Turret requirement

• Tailstock requirement

• Tooling requirements
