Overview

This document is a multilingual user manual (DE, EN, FR, IT, ES) for the GARANT Feinspindel-System, a precision boring system designed for diameters ranging from 3.0 mm up to 88.1 mm. It covers assembly, maximum operating speeds, fine adjustment procedures, and specifications for various tool sets.

Specifications

• Diameter ranges and tool sets:
• Set 23 7581 / 7586 covers ⌀ 3.0 – 85.9 mm
• 23 7630: ⌀ 9.75 – 15.1 mm, max boring length (L max.) = 30 mm
• 23 7632: ⌀ 14.75 – 20.1 mm, L max. = 51 mm
• 23 7634: ⌀ 19.75 – 25.1 mm, L max. = 72 mm
• 23 7636: ⌀ 24.75 – 30.1 mm, L max. = 82 mm
• Set 23 7586 includes:
• 23 7640: ⌀ 29.75 – 48.1 mm, L max. = 85 mm
• 23 7642: ⌀ 47.75 – 88.1 mm, L max. = 85 mm
• Maximum rotational speeds: Vary by diameter range, with values indicated such as max 1/min (rpm) for different diameter categories (e.g., ⌀ 48 – 88 mm, ⌀ 20 – 48 mm, ⌀ 9.75 – 20 mm).
• Maximum torque: 10 Nm
• Maximum boring length (L max.): Specified per tool insert, critical for operational limits.

Assembly Instructions

The manual includes guidance on proper assembly of the spindle system components, emphasizing adherence to maximum torque (10 Nm) and correct tool selection based on diameter and boring length requirements.

Fine Adjustment Procedure

• Fine adjustment of the bore diameter (⌀) is performed using a micrometric adjustment mechanism.
• A Vernier scale (Nonius scale) is provided for precise measurement and control of diameter adjustments, allowing increments as small as 0.01 mm.
• Adjustment steps involve turning the adjustment knob to increase or decrease the diameter with high precision.

Precision and Quality Notes

The system is designed for outstanding precision, requiring premium tools to achieve micrometer-level accuracy. The document highlights the importance of using the correct tool sets and following adjustment procedures carefully to maintain tolerances within 2 to 10 micrometers depending on the application.
