Speed increasers

Product catalog summary

Overview

Speed increasers, also known as "Moltiplicatori di Giri," are precision-engineered devices designed to enhance machining efficiency by increasing spindle speeds. They reduce cycle times while maintaining high reliability, precision, and versatility, particularly suited for drilling and light milling finishing operations. These units are compatible with both manual loading machine tools and machining centers with automatic tool changers.

Application and Control System

These speed increasers optimize production by minimizing spindle wear and downtime, thereby lowering per-piece costs. Each component is precisely measured and tested in controlled environments using coordinate measuring machines. Assembled units undergo balancing and vibration testing to ensure rotational precision within 0.01 mm.

Technical Features and Construction

Output spindle interfaces with ER16 collets and similar tool holders.
Use of precision preloaded angular contact ball bearings for durability and accuracy.
Grease lubrication (Klüber Isoflex NBU 15) is standard, with options for forced cooling via air, coolant, or micro-oil mist.
Maximum input speed: 4000 rpm; maximum output speed: 19200 rpm standard, up to 24000 rpm with ceramic bearings.
Maximum power rating: 1.7 kW; spindle thrust capacity: up to 380 N.
Unit weight approximately 3.8 kg.

Models and Options

Available models include M16-SK40R, M16-BT40R, and M16-CAT40R, each identified by specific codes. Ceramic bearing variants are available (denoted by suffix 'C'). Optional accessories include watertight ER16 collets, stop-blocks, clamping wrenches, and storage cases.

Standards and Compatibility

Speed increasers comply with ANSI B5.50, CAT40, DIN 69871-A, and BT40 standards, ensuring broad compatibility with various machine tool spindles.

Cooling and Lubrication Recommendations

Forced cooling is advised to maintain optimal operating temperatures and extend bearing life. Recommended methods include air or liquid coolant at pressures up to 70 bar, or micro-oil mist lubrication.
