CT8 High Precision Y-Axis Turn/Mill Center: Technical Overview

Demand for multifunctional, highly rigid turn-mill centers capable of complex and precision machining continues to grow in modern manufacturing. Turning and milling center CT8 with inclined Y axis is a technologically advanced solution that combines high precision, dynamics and compactness in a universal 4-axis platform. It is ideal for serial and small-scale production of precision shafts, discs and parts with complex contours.

CT8 4-Axis Turning and Milling Center with Inclined Y-Axis: External View

1. Machine Overview: Integrated 4-Axis Capabilities

The CT8 is a 4-axis universal turning and milling center equipped with driven tool and C-axis, with a comprehensive basic package:

  • High Power Headstock: Spindle A2-8 with asynchronous motor, power 15/18.5 kW and torque 268 Nm. Maximum speed - 4000 rpm, with full positioning and contouring control C-axis.

  • Universal turret: 12 position power turret BMT65. All positions can be equipped driven tool, which allows you to perform a full cycle of operations (turning, milling, drilling, threading) in one installation.

  • Counter spindle system: Built-in counter spindle (A2-6) With a maximum speed of 5000 rpm, it supports automatic workpiece transfer for complete reverse side processing and synchronous dual-spindle operation.

  • Inclined Y axis: Design with inclined Y axis frame type and ±50 mm stroke provides high rigidity for complex milling operations, eccentric and offset turning.

2. Key technical features

2.1 High rigidity inclined bed and guide system

The machine has inclined bed (45°) Made from high quality cast iron, which provides excellent thermal stability and torsional resistance. All axles are equipped with wide (45 mm) linear guides. The Z axis is designed with 4 guides to prevent collisions with the tailstock and improve smooth movement and processing accuracy.

2.2 Y-axis design

Unlike conventional turning centers, inclined Y axis of CT8 machine significantly expands technological capabilities. It allows you to perform complex operations: eccentric turning, contour milling, angled machining, which makes the machine truly multifunctional machining center.

2.3 Advanced FANUC CNC system

Control is carried out by the system CNC FANUC 0i-TF Plus with a 10.4" display. The system supports external memory up to 2 GB and the EES function (launching programs from external media). Provides high response speed (minimum frame cycle time 1.5 ms), support for multiple coordinate systems and an extensive set of fixed cycles (rough turning, tapping, drilling, parting off), which simplifies programming and increases efficiency.

2.4 Complete closed-loop measurement system and high accuracy

Each axis uses absolute measurement system (encoder). In combination with propeller pitch compensation and backlash this ensures high positioning accuracy according to the standard VDI 3441: ≤6/8/12μm for X/Y/Z axes and repeatability ≤5/6/8μm, which meets the requirements for producing high-precision parts.

3. Main technical characteristics

  • Working area: Max. processing diameter above the bed is 680 mm, recommended turning diameter is 250 mm, rod diameter is ø65 mm.

  • Spindle system: The hole in the spindle is 87 mm, hydraulic hollow clamping cylinder with clamp control.

  • Drive tool: 12 positions, rated power 4.5 kW, max. 5000 rpm, standard interface BMT65.

  • Feed drives: Rapid traverse X/Z - 24 m/min, Y - 12 m/min.

  • Hydraulics and coolant: Hydraulic system pressure - 55 bar, coolant tank capacity - 200 l, included chip collector and a filtration system.

  • Power supply and conditions: Supply voltage 400 V ±10%, max. installation altitude above sea level - 1000 m.

4. Design features and ergonomics

  • Security and management: Fully enclosed protective cover with large viewing window and sliding doors ensures operator safety and excellent visibility.

  • Lubrication and Maintenance: Centralized automatic lubrication system guides and ball screws increase reliability and reduce maintenance costs.

  • Standard equipment: Includes hydraulic 3-jaw chuck with jaw sets, set BMT65 holderschip collector, signal lamp, electrical cabinet heat exchanger, which allows you to start working immediately after installation.

5. Conclusion: A comprehensive solution for complex problems

Turning and milling center CT8 with inclined Y axisWith its rigid design, multifunctional Y-axis, high-performance components, intelligent FANUC CNC control and complete basic equipment, it provides a highly efficient and flexible solution for precision machining. It is especially effective in automotive, aerospace, medical industries and instrument making, where complex parts require high precision and reduced production cycles.
