Modular honing machine series is
adaptable
Modular honing machine series is scaleable from a basic model up to an automated, multi-spindle system with robotic part handling, gauging/SPC and tooling flexibility.
Sunnen's SV-1000 vertical CNC honing machine series is based on an innovative modular design, engineered to scale up from a single-spindle machine to an automated multi-spindle unit for ultra-precise bore sizing and finishing Designed for part diameters of 3-65mm (0.120-2.56in), the SV-1000 series machines can size bores to accuracies of 0.25 micron (0.00001in)

Gun barrels honed to tight tolerances
Honing is earning new respect from barrel makers, says a gunmaker, who related that a firm rough and finish hones hones to within a tolerance of +/-0.000050in on roundness.
Honing systems operate automatically
Latest high technology honing systems are capable of producing and controlling hole sizes automatically within 0.25 micron and to high Cpk requirements, writes Rich Moellenberg.
Sunnen told manufacturingtalk.com that the machines are ideal for honing diesel fuel injectors, gears, small engine cylinders/connecting rods, hydraulic/pneumatic components, and medical devices in medium to high volumes.
At Sunnen's booth No 2120 at the eastern USA's EASTEC exhibition, the SV-1000 will be demonstrated honing a precision aerospace hydraulic valve.
* Designed for future automation - the basic single-spindle SV-1000 module is designed for future automation with removable side enclosure panels to facilitate flow-through part processing.

Sunnen's SV-1005 series vertical CNC honing system is now available with an integrated air gaging system to provide closed-loop control of tool size, along with downloadable SPC data.
Tube honing system raises barrel bore quality
Using a tube honing machine, an armanents manufacturer is realising superior accuracy and easy cleaning that result from the excellent bore geometry and surface finish produced.
Robotic honing has automatic bore sizing
A vertical CNC honing system designed for automatic precision sizing and finishing of deep bores up to 200mm diameter features robotic part loading offers variety of bore-diameter gaging systems.
It is available with a fixed tooling plate or servo rotary table with 12-position rotary air union for fixture control.
An industrial PC control ensures reliability and an easy support path with software-based updates and commercially available replacement parts.
The machine's cast-polymer base provides excellent vibration damping and structural rigidity.
* Automation now - automated versions of the SV-1000 can be specified with the servo rotary table or linear part transfer, integrated part handling systems, and up to four spindles.
For unmanned cellular processing, the SV-1000 can be equipped with integrated post-process air gaging to provide closed-loop control of bore size and geometry, along with downloadable SPC data and feedback control.
Post-process air gaging with one to four servo columns can provide size, taper, and straightness feedback control.
Matched with Sunnen's diamond-plated CGT Krossgrinding tools or MMT TurboHone multi-stone mandrels, the air-gage-equipped machine can automatically control hole size to accuracies of 0.25 micron (0.00001in), eliminating the need for a skilled operator to tweak the process.
A match-honing package can also be added.
* Patented innovations - The SV-1000 features two patent pending innovations: a servo-controlled stroking drive that responds smoothly to motion profiles generated by the control and a load-sensing tool feed system that minimizes processing time by sensing where and how much to hone the bore.
The new stroking drive provides the highest level of flexibility and consistency in spindle reciprocation to allow a new level of process optimization.
Unique in the industry, claimed Sunnen, it enables the SV-1000 to do both conventional honing and single-pass honing with any tool in Sunnen's line, using available adapters, to give the machine excellent small-shop versatility and return on investment.
* Less shop floor space - the vertical design of the SV-1000 conserves shop floor space, requiring just 2400 x 2300 x 2700mm WxDxH (95 x 91 x 107in).
The high-torque, belt-driven spindle is rated at 7.5kW (10HP) to cover a wide range of sizing and finishing work at speeds of 100-4000 rev/min.
* Cells - for custom processing cells, Sunnen can provide post-process inspection and sorting of parts to the submicron level, along with special tooling, robotic integration, part orientation, gaging, and other options integrated for a purpose-designed system based on individual customer requirements.
