400 SBRZ, 600 SBRZ, 400 TBTZ, 400 MBRZ Mass-Centering Machines for Crankshafts ?

Product catalog summary

Overview
The document provides detailed information about mass-centering machines for crankshafts, specifically models 400 SBRZ, 600 SBRZ, 400 TBTZ, and 400 MBRZ. These machines are designed for engine manufacturers involved in mid to high-volume production, offering modular design and automatic operation.

Specifications
The machines feature a modular design allowing for easy changeover between different crankshaft types using various carriages. They support both symmetrical and asymmetrical crankshaft types and can be integrated directly into production lines. The machines process unbalance data from final balancing machines to optimize manufacturing processes.

Design and Operation
The machines are available in single or multi-station configurations with automatic sequences. They can be loaded and unloaded manually or automatically, with options for integration with customer conveying equipment. The design includes a balancing frame supported by round springs, with carriage units mounted on precision bearings. Hydraulic or electro-mechanical drill units are used for center drilling.

Technical Data
The machines are equipped with CAB 950 measuring units and can handle passenger car crankshafts, light commercial vehicles, and trucks. They support varying type programs and automatic sequences of operations. Key specifications include:

Weight capacity: 7 - 50 kg (400 SBRZ, 400 TBTZ, 400 MBRZ) and 40 - 200 kg (600 SBRZ)
Max outside diameter: 220 mm (400 SBRZ, 400 TBTZ, 400 MBRZ) and 320 mm (600 SBRZ)
Main journal diameter: 45 - 80 mm (400 SBRZ, 400 TBTZ, 400 MBRZ) and 70 - 130 mm (600 SBRZ)
Length: 360 - 790 mm (400 SBRZ, 400 TBTZ, 400 MBRZ) and 500 - 1500 mm (600 SBRZ)
Balancing speed: 400 min^-1 (400 SBRZ, 400 TBTZ, 400 MBRZ) and 300 min^-1 (600 SBRZ)

Additional Features
The machines offer high flexibility through sledge construction and can process crankshafts before and after journal preparation. They include integrated lift and carry transporters and allow for combined measurement and centering or separate processes.
