NEW SMTCL HTC30 Series CNC Lathe

SMTCL HTC30 Series Compact CNC Horizontal Lathe

The SMTCL HTC30 Series is a compact two-axis CNC horizontal lathe platform designed for productive machining of shafts, sleeves, bushes, flanges and other small to medium rotational components.

Available in HTC30Q and HTC30H configurations, the Series combines a practical 300 mm turning diameter, 500 mm turning length, 50 mm bar capacity, 8-inch chuck, 4500 rpm spindle speed and 30 m/min X/Z rapid traverse in a relatively compact machine footprint.

Compared with the smaller HTC16 platform, the HTC30 provides increased turning capacity, spindle bore and bar capacity while retaining a production-oriented machine layout.

The HTC30 Series is particularly suitable for general engineering, automotive components, bearing components, medical-related components and other production applications where repeatability, cycle efficiency and compact machine size are important.

High-Efficiency HTC30 Platform

The current HTC30Q/H platform is developed around productive two-axis CNC turning.

Key design priorities include:

• High machining efficiency

• High positioning consistency

• Fast axis movement

• Stable feed performance

• Efficient tool indexing

• Compact production layout

• Suitability for automation and functional upgrades

The 2026 manufacturer product material identifies HTC30Q/H as a key high-efficiency horizontal CNC lathe family.


30 m/min Rapid Traverse

The HTC30 provides:

• X-axis rapid traverse: 30 m/min

• Z-axis rapid traverse: 30 m/min

High rapid traverse helps reduce non-cutting time during:

• Shoulder turning

• Grooving

• Drilling

• Boring

• Threading

• Repeated shaft machining

• Multi-diameter components

This makes the HTC30 particularly suitable for small to medium batch production where cycle time is important.


C3-Grade Ballscrew Feed System

The 2026 HTC30 product material identifies:

• C3-grade precision ballscrews

• Double-fixed pre-tensioned ballscrew structure

• Error-compensation technology

The pre-tensioned feed system helps reduce thermal influence and supports:

• Better positioning consistency

• Stable repeatability

• Reduced thermal drift

• Improved production stability

• More consistent dimensional performance during longer machining cycles


High-Efficiency Servo Turret

The HTC30 Series uses a horizontal 8-station servo turret.

The turret supports:

• Fast tool indexing

• Repeatable tool positioning

• Reduced non-cutting time

• Multi-operation turning

• Small to medium batch production

Typical tool positions may include:

• External turning tools

• Boring tools

• Grooving tools

• Threading tools

• Drilling tools

• Chamfering tools


Production-Oriented Spindle Package

The HTC30 uses:

• A2-6 spindle nose

• 65 mm spindle bore

• 50 mm maximum bar capacity

• 8-inch standard chuck

• 4500 rpm maximum spindle speed

This provides a practical spindle package for:

• Small and medium shafts

• Sleeves

• Bushes

• Flanges

• Bearing-related components

• General turned components

The 50 mm bar capacity also makes the machine suitable for through-spindle production where bar-fed or semi-automatic production is required.


Tailstock Support

The HTC30 uses a tailstock system with:

• 300 mm tailstock travel

• 100 mm quill travel

• 100 mm quill diameter

• MT5 taper

The tailstock provides support for longer shaft-type components and is particularly useful when machining:

• Slender shafts

• Gear shafts

• Motor shafts

• Pins

• Sleeves

• Components requiring centre support


Compact Production Footprint

The HTC30 has an approximate machine size of:

2295 × 1680 × 1650 mm

and an approximate machine weight of:

3500 kg

This provides useful production turning capacity without requiring the larger footprint of HTC40 or HTC50 machines.

The compact footprint is particularly attractive for:

• General engineering workshops

• Small production shops

• Toolrooms

• Multi-machine production cells

• Workshops upgrading from manual or flat-bed CNC lathes


Typical Applications

The HTC30 Series is well suited to:

• General engineering

• Automotive components

• Bearing components

• Medical-related components

• Hardware components

• Motor components

• Pump and valve components

• Hydraulic components

• Shaft production

• Sleeve and bush production

• Flange machining

• Small to medium batch production


Typical Workpieces

Typical workpieces may include:

• Motor shafts

• Gear shafts

• Straight shafts

• Pins

• Sleeves

• Bushes

• Bearing components

• Flanges

• Spacers

• Valve parts

• Small disc-type components

• General precision-turned parts
