Automotive - ROBBI
Line boring machines models R2000
Simple, but very accurate, convenient and reliable machines for machining bearing bores, and camshaft bores from 22 to 200 mm diameter in the cylinder blocks and heads of any engines. There are 4 models with difference in the maximum allowable length of the machining cylinder blocks: R2000 / B (1800 mm), R2000 / C (2200 mm), R2000 / C SPEC (2600 mm) and R2000 / D (3200 mm). Coloring the machines in to any color at the customer's request.
TECHNICAL FEATURES:
Bed
Heavy bed made of stress-relieved and ribbed cast iron to assure stability and vibration free boring.
Workpiece setting up
Approximative centering by means of cones and final centering by means of two universal centering devices with dial indicator. A bridge comparator holder secures a perfect alignment of boring bar as to the block surface.
Work head
Work head is mounted on a vertically and transversally adjustable support to allow a fast and accurate alignment. Controls grouped in the head for an easy and handy operation. Boring spindle with two limit stops. Automatic workhead lubrication.
Boring bar supports
Bar supports vertically adjustable and movable on all working surfaces. Adjustable bar bearings with possibility to swing and shift crosswise to permit a fast alignment.
 
Controls on the working headstock and columns
 
The universal centering device, the tool setting micrometer, the boring head and spot facing device with automatic feed
