• Net machine weight ranges from 19,500 kg (42,900 lb) to 39,500 kg (86,900 lb).

Axis Travel and Movement
Axis travel distances and feed rates are specified:

• X-axis (table front/back) travel ranges from 2,000 mm (78.74 in.) to 5,000 mm (196.85 in.).
• Y-axis (spindle head horizontal) and Z-axis (quill vertical) travel values are partially provided, with some values around 1,000 to 1,600 mm.
• Cutting feedrate and rapid traverse rates are mentioned but exact values are incomplete or missing.

Table and T-Slot Details
Tables feature T-slots for workpiece mounting:

• T-slot width is 20 mm (0.79 in.) with 9 slots, spaced at 200 mm (7.87 in.) center-to-center.
• Some models have T-slots spaced at 140 mm (5.51 in.).

Load Capacity and Tooling
Load capacities increase with machine size:

• From 6,000 kg (13,200 lb) up to 20,000 kg (44,000 lb).

Tooling specifications include:

• Tool shank type: MAS403 BT50.
• Tool magazine capacity options: 24, 50, 72, or 100 tools.
• Maximum tool diameter ranges from 128 mm (5.04 in.) with adjacent tools to 230 mm (9.06 in.) without adjacent tools.
• Maximum tool length is 150 mm (5.91 in.).
• Maximum tool weight and moment: 40/20 kg x mm (15.75/44 lb x in.).
• Tool selection method: Fixed address random selection.

Spindle and Motor Specifications
Spindle and motor details include:

• Spindle speed ranges: 30 to 4,000 rpm standard, optional 6,000 rpm and 10,000 rpm variants.
• Spindle taper: 7/24 taper No. 50.
• Pull stud type: MAS 2.
• Spindle bearing diameter: 210 mm (8.72 in.).
• Spindle drive power: 22 kW (30 hp) continuous, with options for 18.5 kW (25 hp) and other variants.
• Brushless servo motors for spindle head and table: approximately 4.2 to 4.6 kW (5.6 to 6.1 hp).
• Quill and crossrail vertical drives also use brushless servo motors around 3.5 to 3.7 kW (4.8 to 4.9 hp).

Additional Features and Notes
The document references:

• Auto-positioning crossrail specifications.
• Machine control unit: MCV-AII series.
• Height and travel parameters for quill and spindle head.
• Rapid traverse and cutting feedrate values are partially specified but incomplete.
• Optional spindle speeds and configurations are indicated with brackets and braces.

Summary
This technical data sheet details the physical dimensions, load capacities, tooling options, spindle and motor specifications, and operational parameters for a series of large CNC milling machines. The machines vary primarily by table size and travel distances, with corresponding increases in weight capacity and floor space requirements. The tooling system supports a large number of tools with flexible selection methods, and the spindle system offers multiple speed options with robust motor drives. The data is essential for selecting the appropriate machine model based on workspace, load, and machining requirements.
