HMC-H Series Positioning

The HMC-H Series is positioned as SMTCL’s high-precision horizontal machining-centre platform.

The manufacturer highlights three principal strengths:

• High precision

• High rigidity and stability

• High production efficiency

The HMC-H Series is particularly suited to high-value components where machining accuracy, repeatability and stable batch production are important.


T-Shaped Machine Structure

The HMC80H uses an overall T-shaped machine structure.

This architecture supports:

• High rigidity

• Stable axis geometry

• Good load distribution

• Strong multi-face machining capability

• Reliable production performance

The horizontal arrangement is particularly suitable for large box-type, housing-type and prismatic components.


Heavy-Duty Roller Linear Guideways

The H Series uses heavy-duty roller linear guideways.

The manufacturer highlights:

• Strong load-bearing capacity

• High accuracy

• High stability

The X-axis guideway mounting surface uses a large-span, low-centre-of-gravity design.

This helps improve:

• Machine rigidity

• Dynamic stability

• Resistance to cutting loads

• Machining consistency


Precision Ballscrew Feed System

The transmission system uses precision ballscrews with carefully arranged bearings.

This design helps reduce:

• Ballscrew heating

• Bearing heating

• Thermal deformation

Benefits include:

• Improved positioning accuracy

• Stable feed performance

• Better long-cycle machining consistency


Integral Double-Wall Column

The column uses a double-wall structure.

The Y-axis motor seat and column are integrally cast.

This helps improve:

• Structural stiffness

• Y-axis stability

• Positioning consistency

• Long-term machine accuracy


Thermally Symmetrical Spindle Box

The HMC-H spindle box uses a thermally symmetrical structure.

This improves control of thermal deformation during sustained machining.

The H Series also uses a two-step gear transmission.

This allows the spindle to support:

• Higher-speed machining

• High-torque cutting

• Broad general machining applications


High-Rigidity Dual-Pallet Worktable

The HMC80H uses an 800 × 800 mm dual-pallet worktable system.

Key characteristics include:

• 2000 kg pallet capacity

• Standard 1° indexing

• Optional 0.001° CNC rotary positioning

• Four extra-large positioning cones

• Air-tightness detection

The four large positioning cones increase worktable rigidity and help provide accurate, repeatable positioning.


Dual-Pallet System

The standard machine includes:

• Two pallets

This allows one pallet to be loaded or unloaded while the other is used for machining.

Benefits include:

• Reduced machine idle time

• Faster workpiece changeover

• Improved production efficiency

• Better suitability for batch production

Pallet exchange time is approximately:

• 18 seconds


Optional 0.001° CNC Rotary Table

For applications requiring fine angular positioning, an optional high-precision rotary table is available.

Minimum indexing:

• 0.001°

This can support:

• Complex multi-angle machining

• Precision bore patterns

• Angular features

• Reduced re-clamping

• More flexible multi-face machining


Large Workpiece Capacity

The HMC80H can accommodate workpieces up to approximately:

• Ø1250 mm maximum swing diameter

• 1200 mm maximum height

Combined with a:

• 2000 kg pallet load

this makes the machine suitable for larger housings and substantial industrial components.


Tool Magazine Flexibility

The HMC80H can be configured with:

• 40-tool magazine

• 60-tool magazine

• 90-tool magazine

• 120-tool magazine

The manufacturer uses a precision chain-type tool magazine and automatic tool-change mechanism.

Key features include:

• Tool pre-selection

• Rapid tool changing

• Cam-type tool-change mechanism

• Support for long and large-diameter tools

• Optional servo-driven tool magazine


High Production Efficiency

The HMC80H combines several productivity features:

• Dual-pallet system

• 24 m/min rapid traverse

• 3.5-second tool-to-tool change

• Tool pre-selection

• Multiple ATC capacity choices

• Automation interface

This makes the machine particularly suitable for repeat production of complex multi-face components.


Typical Machining Operations

The HMC80H can support:

• Milling

• Face milling

• Boring

• Precision boring

• Drilling

• Tapping

• Reaming

Why Consider the HMC80H?

The HMC80H is a strong choice where larger workpiece capacity is required without moving into the largest HMC class.

Key reasons to consider the HMC80H include:

• 800 × 800 mm pallet

• 2000 kg pallet load

• Dual-pallet system

• X/Y/Z travels of 1350 / 1100 / 1100 mm

• Ø1250 mm maximum workpiece swing

• 1200 mm maximum workpiece height

• BT50 spindle

• 6000 rpm mechanical spindle

• 22 / 26 kW spindle power

• Up to approximately 851 Nm spindle torque

• Optional 10,000 rpm motor spindle

• 24 m/min rapid traverse

• 40-tool standard ATC

• 60 / 90 / 120-tool magazine options

• Standard 1° B-axis indexing

• Optional 0.001° CNC rotary table

• Heavy-duty roller linear guideways

• Precision ballscrew system

• Thermally symmetrical geared spindle box

• High precision and stable production capability


HMC80H Compared with HMC63H

HMC63H

• Pallet: 630 × 630 mm

• Load: 1200 kg

• XYZ: 1000 / 900 / 900 mm

• Maximum workpiece: Ø1000 × 1000 mm

• Spindle: BT50, 6000 rpm

• Power: 18.5 / 22 kW

• Torque: 605 / 718 Nm

• Rapid traverse: 30 m/min


HMC80H

• Pallet: 800 × 800 mm

• Load: 2000 kg

• XYZ: 1350 / 1100 / 1100 mm

• Maximum workpiece: Ø1250 × 1200 mm

• Spindle: BT50, 6000 rpm

• Power: 22 / 26 kW

• Torque: 718 / 851 Nm

• Rapid traverse: 24 m/min


Choose HMC63H when:

• Components fit comfortably within the 630 mm pallet platform

• 1200 kg pallet capacity is sufficient

• Higher rapid traverse is beneficial

• A more compact machine is preferred


Choose HMC80H when:

• Larger and heavier components are common

• 2000 kg pallet capacity is required

• Greater X/Y/Z travel is needed

• Higher spindle torque is beneficial

• A larger workpiece envelope is required


HMC80H Compared with HMC100H

HMC80H

• Pallet: 800 × 800 mm

• Load: 2000 kg

• XYZ: 1350 / 1100 / 1100 mm

• Maximum workpiece: Ø1250 × 1200 mm

• Spindle: 6000 rpm

• Power: 22 / 26 kW

• Torque: 718 / 851 Nm


HMC100H

• Pallet: 1000 × 1000 mm

• Load: 2000 kg

• XYZ: 1350 / 1100 / 1050 mm

• Maximum workpiece: Ø1250 × 1200 mm

• Spindle: 6000 rpm

• Power: 22 / 26 kW

• Torque: 718 / 851 Nm


The main difference between HMC80H and HMC100H is therefore not spindle power or maximum workpiece envelope.

The HMC100H provides:

• Larger 1000 × 1000 mm pallet

while retaining the same 2000 kg pallet load and broadly similar machining envelope.

Choose HMC80H when:

• An 800 × 800 mm pallet is sufficient

• 1100 mm Z travel is useful

• A more compact pallet format is preferred


Choose HMC100H when:

• A 1000 × 1000 mm pallet provides a fixture or workpiece-support advantage

• Larger base footprint is more important than additional Z travel


HMC-H Compared with HMC-S

HMC-H

Focus:

• High precision

• High efficiency

• High stability

• Heavy-duty roller linear guideways

• Broad production flexibility


HMC-S

Focus:

• Heavy-duty cutting

• High rigidity

• High metal-removal rates

• Hardened steel guideways

• Large-volume cutting of castings and steel components


The HMC80H should therefore not be positioned as simply a lighter HMC80S.

HMC80H is the precision / efficiency-oriented platform.

HMC80S is the heavy-cutting platform.
