HMC-H Series Positioning

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


T-Shaped Machine Structure

The HMC50H 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 suited to 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 a carefully arranged bearing system.

This is intended to 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.

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

This allows the machine to support both:

• Higher-speed machining

and

• Higher-torque cutting

The thermally symmetrical structure helps control deformation during extended production cycles.


High-Rigidity Dual-Pallet Worktable

The HMC50H uses a 500 × 500 mm dual-pallet worktable system.

Key characteristics include:

• 600 kg pallet capacity

• Standard 1° indexing

• Optional 0.001° CNC rotary positioning

• Four extra-large positioning cones

• Air-tightness detection

The positioning-cone arrangement increases worktable rigidity and helps provide accurate, repeatable pallet 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:

• 12 seconds


Optional 0.001° CNC Rotary Table

For applications requiring fine angular positioning, an optional high-precision rotary worktable 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


Compact Workpiece Envelope

The HMC50H can accommodate workpieces up to approximately:

• Ø700 mm maximum swing diameter

• 800 mm maximum height

Combined with:

• 600 kg pallet load

this makes the machine particularly suitable for smaller and medium-size precision housings and production components.


High Production Efficiency

The HMC50H combines several features intended to reduce non-cutting time:

• Dual-pallet system

• 30 m/min rapid traverse

• 3.5-second tool-to-tool change

• Tool pre-selection

• 40 / 60 / 90 / 120-tool magazine choices

• Automation interface

This makes the machine well suited to repeated production of complex multi-face components.


Typical Machining Operations

The HMC50H can support:

• Milling

• Face milling

• Boring

• Precision boring

• Drilling

• Tapping

• Reaming

• Pocket machining

• Hole-system machining

• Multi-face machining


The horizontal configuration is particularly useful where several related faces and bores must maintain accurate positional relationships.
