Machine Model Variants and Controlled Axes

The document compares specifications for several machine models: 1750 1ST, 1750 2ST, and 1750 2SC. All models feature 2 controlled axes.

Dimensions and Travel Parameters

• Swing over bed: Not explicitly stated.
• Swing over saddle: Not explicitly stated.
• Maximum turning diameter (upper): 500 mm (19.69 in.) for some models; other models show larger diameters up to 840 mm (33.07 in.).
• Maximum work length (upper): Values vary, with some models showing up to 2,090 mm (82.28 in.) and 2,025 mm (79.72 in.).
• Travel distances: XA-upper travel ranges around 470 mm (18.50 in.) to 650 mm (25.59 in.); ZB-lower travel up to 1,015 mm (39.96 in.) or more.

Spindle Specifications

• Spindle diameters: Range from ø220 mm (8.66 in.) to ø380 mm (14.96 in.) depending on model.
• Spindle nose types: JIS A2-11, JIS A2-15, and JIS A2-20.
• Spindle bore diameters: From ø142 mm (5.59 in.) to ø275 mm (10.83 in.).
• Spindle speeds: Variable ranges from 10 to 2,000 min-1 depending on model.
• Spindle speed control: Infinitely variable with 2 or 4 automatic ranges.

Tooling and Turret

• Upper tools available; lower tools generally not specified or absent.
• Tool outer/inner diameters and turret configurations vary, with turret stations ranging from 8 to 12.
• Sleeve diameter typically 180 mm (7.09 in.) with Morse Taper 6.

Feed and Servo Power

• Rapid traverse rates and minimum/maximum feed rates are specified but vary by model.
• Servo power for XA/ZA axes ranges from approximately 2.4 kW to 5.2 kW (3.26 hp to 7.0 hp).
• Some models include direct drive with thrust forces up to 7.0 kN (1,574 lbf).

Physical and Installation Data

• Floor space requirements vary, with some models requiring up to 6,060 mm x 2,832 mm (238.58 in. x 111.50 in.).
• Net weights range from approximately 22,800 kg (50,160 lb) to 25,500 kg (56,100 lb).

Additional Notes

• Spindle tailstock specifications include diameters and Morse taper sizes (MT 5 or MT 6).
• Feed resolution is very fine, with increments as small as 0.001 mm (0.000040 in.).
• Chuck sizes and capacities vary, with some models supporting up to 1,030 mm (40.55 in.) chucks.

Summary

This document provides detailed technical specifications for a series of CNC turning machines with 2 controlled axes. Key parameters include spindle size and speed, travel distances, tooling configurations, servo power, and physical dimensions. The data supports selection and comparison of machine models based on machining capacity, precision, and installation requirements.
