This second generation machining business is using a new technology that makes a 60 millionths tolerance look generous. No kidding.
Dart masters the "peaks and valleys" of custom engine block production with an advanced American-made Sunnen SV-20 flexible honing system that uses programmable control to replicate “best” engine parameters and produce expert results with minimal operator expertise.
Damen Carbide Tool Co.
expands its holemaking capability and business base with honing capacity to 9 in diameter and a 60 in stroke length using hones from Sunnen
Exotic materials specialist
Engine remanufacturer Jasper Engines & Transmissions and engine builder White Performance & Machine are two shops with different needs that illustrate how new diamond honing abrasives technology from Sunnen simplifies the boring process, cuts cycle times as much as half, and improves dyno results.
Sunnen HTA hone is PLC controlled, handles parts up to 13.5 ft long, 21 in diameter and 8000 lbs.
Ideal for bore resurfacing, the
The SV-20 honing system from Sunnen Products is the first competitively priced large-part machine for job-shop part production with a true linear, vertical, servo-stroking system to produce precision bore geometries on compressors, oilfield components, automotive/truck blocks and similar parts.
Sunnen servo-controls the force in the honing tool feed system to maintain the optimum cutting load on the honing abrasive throughout a cycle, irrespective of the incoming part's hardness, geometry or size variation.
