NEW SMTCL HTC40 Series Slant Bed CNC Lathes

SMTCL HTC40 Series Slant Bed CNC Lathes

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

The Series provides a choice between HTC40H(Q) configurations for general production turning and HTC40S configurations for applications requiring larger bar capacity, larger chuck size, higher spindle power and stronger cutting performance.

Available turning lengths range from 500 mm to 1500 mm depending on configuration.

The HTC40 Series is particularly suited to general engineering, automotive components, hydraulic components, maintenance production, mining support work and small to medium batch manufacturing where a compact production-oriented turning centre is preferred over a conventional flat bed CNC lathe.

Slant Bed Production Platform

The HTC40 Series uses a slant bed layout intended for production-oriented turning.

Compared with a conventional flat bed CNC lathe, the slant bed configuration provides practical advantages including:

• Improved chip evacuation

• Better access to the turret and work zone

• Improved enclosure integration

• Good production stability

• Easier automation integration

• Compact machine layout

This makes the HTC40 Series particularly attractive to workshops moving from manual or flat bed CNC turning into more repeatable production machining.


Fast Axis Movement

The HTC40H(Q) provides rapid traverse speeds of:

• X axis: 30 m/min

• Z axis: 30 m/min

The HTC40S provides:

• X axis: 20 m/min

• Z axis: 20 m/min

The H/Q configuration therefore places more emphasis on reducing non-cutting time, while the S configuration places greater emphasis on stronger machining capability.


Servo Turret

Most HTC40 configurations use a horizontal 8-station servo turret.

These include:

• HTC40H(Q)/500

• HTC40H(Q)/1000

• HTC40S/500

• HTC40S/1000

The HTC40S/1500 uses a:

• Horizontal 12-station servo turret

The turret system supports:

• Multi-operation turning

• Fast tool indexing

• Repeatable tool positioning

• Batch production

• Reduced manual tool intervention

Nearby tool selection is listed for all five configurations.
