NEW SMTCL T-Force Series CNC Floor Milling and Boring Machine

NEW SMTCL T-Force Series CNC Floor Milling and Boring Machine

The SMTCL T-Force Series is a high-capacity CNC floor milling and boring machine platform designed for large precision workpieces requiring a combination of heavy-duty cutting capability, long machining travel, high structural rigidity and stable accuracy.

The current T-Force range includes three principal spindle classes:

• T-Force 160R

• T-Force 200R

• T-Force 260R

The Series uses a floor-type configuration that allows very large workpieces to remain stationary while the machine travels along the X axis.

Depending on model, the T-Force Series provides spindle diameters from 160 to 260 mm, X-axis travel from 6000 mm to 10000 mm as a base specification with extension in 2000 mm increments, Y-axis travel up to 7000 mm, Z-axis ram travel up to 1800 mm and W-axis boring-spindle travel up to 1800 mm.

Maximum spindle torque reaches approximately 38,000 Nm on the T-Force 260R, making the Series suitable for large precision components, heavy boring, large-diameter milling and demanding engineering applications.

Typical industries include wind power, energy, power generation, shipbuilding, steam-turbine manufacturing and general machinery.

Floor-Type Machine Concept

A floor-type milling and boring machine is particularly suitable where the workpiece is too large or too heavy to move efficiently on a conventional machine table.

The workpiece is normally installed on a floor plate or rotary worktable while the machine column travels along the X-axis bed.

This configuration provides practical advantages for:

• Very large workpieces

• Long components

• Heavy fabricated structures

• Large housings

• Large rotating components

• Components requiring machining from multiple positions

• Projects requiring very long X-axis travel


Closed Constant-Flow Hydrostatic Guideways

One of the defining technical characteristics of the T-Force Series is its hydrostatic guideway system.

The X, Y and Z axes use closed constant-flow hydrostatic guideways.

An imported constant-flow multi-head pump supplies the hydrostatic guideway system.

This arrangement provides:

• High load-bearing capability

• Strong vibration resistance

• Low friction

• Stable movement under heavy load

• Good accuracy retention

• Suitability for heavy-duty cutting

The hydrostatic guideway arrangement is particularly valuable on large machine tools where the moving masses and cutting forces are substantially greater than those of conventional machining centres.


High-Accuracy Imported Spindle Group

The T-Force Series uses a high-accuracy imported spindle group.

The manufacturer identifies the spindle group as originally imported from Germany A. Mannesmann.

The spindle system also incorporates imported high-accuracy spindle bearings.

Spindle bearing lubrication uses an oil-and-air lubrication system.

The spindle arrangement is intended to provide:

• High rotational accuracy

• Strong bearing capacity

• Stable high-load operation

• Reduced bearing heating

• Long-term machining stability


High Torque and Full-Gear Transmission

The T-Force platform uses a full-gear spindle transmission system designed to combine large torque with an appropriate machining speed range.

Depending on configuration, the spindle transmission uses automatic hydraulic gear shifting.

This allows the machine to provide:

• High spindle torque at low speed

• Useful speed range for milling and boring

• Stable heavy-cutting performance

• Improved matching between cutter size and spindle speed

The largest T-Force 260R configuration provides maximum spindle torque of approximately 38,000 Nm.


High-Accuracy and High-Rigidity Ram

The T-Force ram is manufactured from high-strength ductile cast iron.

The ram incorporates compensation technology designed to control deflection as the ram extends.

The manufacturer uses:

• Double hydraulic cylinders

• Proportional-valve control

• CNC compensation

to compensate for ram deflection.

This helps maintain machining accuracy as the Z-axis extension changes.


Headstock Centre-of-Gravity Compensation

Large floor boring machines must compensate for the changing load and position of the headstock.

The T-Force platform incorporates headstock centre-of-gravity compensation.

Depending on axis and machine structure, the manufacturer uses combinations of:

• Hydraulic cylinders

• Proportional valves

• Double motors

• Double ballscrews

• Double linear scales

• CNC control

This helps maintain stable machine geometry and axis performance throughout the working range.


Dual-Motor Y-Axis Drive

The Y axis uses a dual-motor and dual-ballscrew drive arrangement.

This structure is intended to improve:

• Movement stability

• Drive rigidity

• Load distribution

• Positioning consistency

• Dynamic behaviour of the headstock assembly


Full Closed-Loop Position Control

The T-Force platform uses linear scales to provide full closed-loop axis measurement.

Full closed-loop control helps reduce the effect of:

• Ballscrew error

• Transmission error

• Thermal displacement

• Long-axis accumulated positioning error

This is particularly important on machines where X-axis travel may extend well beyond 10 metres.


High-Stability Machine Structure

The manufacturer places strong emphasis on structural and long-term stability.

Key structural components include:

• Machine body

• Sliding seat

• Column

• Headstock

These components use high-strength grey cast iron produced using resin-sand moulding.

The ram and main gearbox use high-strength ductile cast iron.

This combination provides:

• Good vibration absorption

• High structural stiffness

• Strong load-bearing capability

• Stable machining performance


Finite-Element Reliability Design

The basic machine structure is developed using finite-element simulation and forward reliability analysis.

This process is used to optimise:

• Structural stiffness

• Stress distribution

• Load paths

• Machine stability

• Long-term reliability


Casting Stabilisation

Major cast components undergo stress-relief processes including:

• Natural ageing

• Thermal ageing

• Vibration ageing

These processes are used to release residual casting stress and improve long-term dimensional stability.


Low-Stress Precision Assembly

Important mounting surfaces such as:

• Bearing seats

• Nut seats

• Ballscrew seats

are finished using controlled scraping processes.

This provides:

• High contact ratio

• Reduced assembly stress

• Stable geometry

• Improved long-term accuracy retention


Extensive Quality Control

The manufacturer identifies a comprehensive process-control system including:

• 138 process inspection and control items

• Full machine acceptance testing

• 179 machine accuracy inspection items

These inspection procedures are intended to maintain consistent product quality and long-term machine accuracy.
