Honing system for precision finishing

SUNNEN’S new SV-400 Series vertical CNC honing system combines a wide choice of tooling options, large work envelope, and up to 1,524mm stroke for bore sizing of small and medium-sized gas/ diesel engine blocks, oil/gas components, hydraulic/pneumatic parts, compressors, bearing sleeves, gear hobs and similar small or large multi-bore parts. A work envelope of 915 x 1,015mm (36" x 40") and weight capacity up to 90kg (2,000lb) provide versatility for processing a wide range parts. An optional tool-guide assembly and variety of bore-diameter gauging systems combine with a servo-controlled X-axis travel of 1,143mm to allow automated honing of multi-bore blocks with high precision. Straightness sensing capability provides a display of the bore profile during the cycle. Combined with a patented, servo stroking system, it allows the SV-400 to auto-dwell in any part of the bore to correct straightness automatically in the shortest cycle time. The SV-400 can be used to hone parts with inside diameters from 19 to 200mm ), or diesel liners up to 150mm, depending on the tool options selected.

Designed for automated processing of mid to high part volumes, the SV-400 Series features full-height access doors and enclosure pre-configured for use with robotic part loading systems, while the CNC control includes a built-in automation interface. A 20-amp power supply and multiple E-stop contacts add versatility and allow convenient automation control. Setup is simplified with a multi-axis hand wheel for fine-tuning vertical stroke, tool feed, column position (SV-410 only) and optional cradle position. Automatic tool feed can be selected for constant load or constant rate. The PC-based, colour touch-screen control features multi-language capability, pull-down menus, unlimited capacity for job setups, and programmable custom tools. In addition to optional in-process air gauging, a variety of optional post-process air-gauge systems can integrate with the control for SPC data collection, as well as automatic compensation of size, taper and straightness. The control allows easy programming of multiple bore positions. The SV-400 Series is built on a malleable iron base for rigidity and vibration damping.

The machine’s servo-controlled, straight-line stroke motion is driven by a ballscrew at rates of 1-160 strokes per minute, while a powerful 7.5kW (10 HP) spindle provides ample torque for fast metal removal with tools outfitted with metal-bond cubic boron nitride and diamond abrasives or standard aluminium oxide and silicon carbide stones.

The new SV-400 Series vertical CNC honing system

Integrating new and revamped machines EUROMAQUINA sells and revamps new and second hand machinery. It can also match the demand for revamped machines being integrated in line. This means that the manufacturer of tubes does not only have the choice between a new line and second hand stand-alone machines, but also can go for an integrated line in which some of the machines are reconditioned. Three items have been newly designed under modular concepts: loading tables (including a special feature for diameter selection linked to channel size); roll ways; and exit cradles. The design was made in 3-D, which is close to manufacturing and assembly and allows to “play” with all perspectives during conceptual layout discussion. Offers can be prepared very easily to match a general layout idea of the customer. The premises were reducing pieces by fixing standards also for options, facilitating expandability by easy interfaces and standardised dimensions, easy access for assembly, disassembly and maintenance. The result is that Euromaquina may offer finishing machines revamped to new – from pointing to packaging machines, including draw bench, straightener, cutting, bevelling or de-burring machine within an integrated solution at a very reasonable price and within a relatively short delivery time.
