TC-S2DN

TC-S2DN-O / TC-S2DN-S

Constantly developing standard machine,
having helped improve the productivity of machining parts and the environmental measures.

Recommended machining

High Productivity

Tool change time has been greatly reduced to achieve high productivity.

The cycle time for mass production workpiece machining program is compared to that of the #40 Machining Center(M/C).

Major machining details

New magazine turning mechanism(Driven by AC servomotor)

The turning mechanism has been redesigned to greatly reduce the tool change time. The magazine is servomotor driven to achieve smooth turning.

Nonstop ATC

The high acceleration/deceleration spindle motor used enables the spindle to start or stop in short time. Tool change can be completed without stopping the Z-axis.

* The data varies depending on the position of the spindle(Z-axis) and program details.

Cutting Performance

Optimized structure and arrangement of ribs achieve higher machine rigidity.
Addition of high-torque specifications lead to high cutting performance.

Highly rigid machine structure

The machine needs to be rigid to ensure high cutting ability. The shape of the base and column, and the arrangement of the ribs have been optimized through CAE analysis.
The improvement of various internal sections has achieved stable cutting performance that does not depend on the spindle speed.

High-torque spindle motor

High torque in the medium and high-speed range is one of the features of the TC's spindle motor. The new high-torque motor further enhances torque in the medium and high-speed range, and also greatly improves torque in the low-speed range. A wider variety of machining, including large hole drilling and tapping, is possible.

* This function is effective when the 10,000min^-1 high-torque specifications is selected.

BT dual contact spindle(BIG-PLUS)

Improved tool rigidity reduces vibration during machining and tool tilt. In addition to this, air assisted tool washing prevents chips being caught between the tool and the spindle.

* This specification can be selected.

Heat expansion compensation systemII

The sensorless heat expansion compensation system has been modified to include a function that compensates for biased heat expansion due to the influence of heat generated by the motor or depending on the axis moving position. More stable compensation ensured.

High speed spindle specifications
(27,000min^-1) * Option

By our high speed spindle specification, the machine feed rate can be increased to further help improve machine productivity. Also, by using the High accuracy mode All. High speed 3D maching with high machining accuracy and surfacequality can be achieved.

Environmental Measures

Low power and air consumption greatly reduces CO₂ emissions, creating an earth-friendly plant environment.

Low power consumption

Low power consumption is achieved by using a highly efficient motor to drive the spindle and a low-inertia spindle.

* Data taken by running machining program created by Brother

Low air consumption

The structure of the spindle covering has been enhanced to reduce air purge. Air blast operations have also been reviewed to optimize the air discharge timing. These improvements have greatly reduced air consumption.

Reliability

Measures for chips based on Brother's accumulated expertise, fully demonstrates their effects on high-speed and highly efficient machining.

Tool washing(Air assist type) * Option

Discharge pressure and flow has been increased to efficiently remove chips attached to the holder.
A filter clog warning function has been added.

Z-axis metal solid cover
Column plate cover

A Z-axis metal slid cover is used, eliminating damage to the cover due to chips. This prevents direct splashing of coolant and reduces the influence of thermal distortion.

Usability

Usability has been enhanced to minimize incorrect operations or entries.
Various user-friendly functions have been prepared to make operation much easier.

12.1-inch color display

User-friendly screen configuration, including graphic drawing, menu screens for program creation, alarm recovery screens, etc.

High accuracy mode AII

In addition to the function to improve the shape, a smoothing function to improve the surface quality has been added to enable more accurate finishing. Minute block processing capability has also been greatly improved to ensure high-speed and highly accurate shape machining.
