CNC-120RB~250RB

Product catalog summary

Overview: This document provides technical specifications and details for CNC Rotary Tables, specifically models CNC-120RB, CNC-170RB, CNC-200RB, and CNC-250RB. These tables are designed for vertical use only and are suitable for small-sized CNC machining and tapping centers.

Specifications:

Table Diameter: Ranges from 120 mm (4.72 inches) to 250 mm (9.84 inches) depending on the model.
Center Height in Vertical: Varies from 115 mm (4.53 inches) to 185 mm (7.28 inches).
Overall Height in Vertical: From 250 mm (9.84 inches) to 365 mm (14.37 inches).
Thru-Hole Diameter: Ranges from 30H7 (1.18H7 inches) to 70H7 (2.75H7 inches).
Servo Motor Types: Options include MELDAS, FANUC, SIEMENS, and HEIDENHAIN.
Gear Ratio: 1:60 for CNC-120RB and 1:90 for other models.
Max RPM: 33.3 for CNC-120RB and 22.2 for other models.
Clamping Force: Pneumatic and hydraulic options available with varying force levels.
Indexing Accuracy: Ranges from 60" to 15" depending on the model.
Repeatability: Unidirectional and bidirectional repeatability is consistent across models.
Max Machining Force: Varies from 12 kg•m to 45 kg•m.
Max Load: Vertical and horizontal load capacities differ by model.

Accuracy Standards: The document outlines specific accuracy standards for table top flatness, parallelism, runout, and perpendicularity, with measurements provided in millimeters.

Additional Features:

Back-mounted motor to avoid interference with machine splash guards.
Up and backside cable outlet options, with a slant motor cover available.
Standard accessories include eye bolts and clamping blocks.
Optional accessories and adaptations for tailstock and controllers are referenced in other pages.

Notes: The document states that GSA reserves the right to modify specifications according to customer requirements.
