Automotive - DALCAN Machines Denmark:
Line-boring machines models LBM
Simple, but very accurate, convenient and reliable machines for machining main bearings bores in engine blocks, as well as camshaft bearing bores in cylinder heads. Two models are produced, differing by the maximum permissible length of the cylinder blocks - LBM 1500 (1500 mm) and LBM 2500 (2500 mm). The coloring of the machines is in red, but any color can also be ordered at the customer's request.
TECHNICAL FEATURES:
Bed
Heavy bed is made of aged iron with stiffeners, eliminating the influence of vibrations on the machining accuracy.
Cylinder block Installation and adjustment
Centering of the part is made preliminary by means of cones, then the final centering is made with two universal centering devices with dial gauge. Special calipers ensure accurate alignment of the boring bar position with respect to the block surface. This guarantees the complete versatility of the machine for the repair of any bearings with a boring range from 24 to 225 mm.
Boring head
The boring head is mounted on a vertically adjustable support, which ensures a fast and accurate alignment of the spindle position with respect to the boring bar. Controls are grouped on a remote control on the boring head for the operator convenience. Spindle speed and feed have infinitely adjustment with reversal direction. Boring spindle has two stops and the possibility of using extension bars to increase of boring length. The boring head gear has automatic lubrication.
Boring bar bearings
The boring bar bearings are vertically adjusted, rotated and moved in all planes. Floating and adjustable boring bar bearings with the possibility of transverse movement allow quick adjustment of the block position.
