Sunnen Products Company products

The Sunnen MBB-1660 prepares a job shop for any type of I.D. work. One of our most versatile honing machines, the MBB-1660 guarantees precision sizing, geometric accuracy and a highly controlled finish on every part. Its quick setup and easy customization makes it a highly economical choice for short-run jobs in both production and salvage settings.

Sunnen`s new SVL-2115 automated lapping machine brings increased productivity and part consistency to what is traditionally a manual process. Based on the same machine platform as the popular SV-2100 honing system, the SVL-2115 provides single setup processing of hydraulic valves, sleeves, fuel system components and other parts that are prone to distortion when honed. The walkaway system uses an index table to automatically lap and air gage bores throughout the cycle. Gage readings are fed back to the control and the cycle is repeated until the parts are within spec.

Sunnen’s patent-pending lapping tools (laps) were developed to work in tandem with the unique feed system in our popular new SVL-2115 lapping system. This combination of machine and tooling brings automatic operation, consistency and productivity to what had previously been a manual process. Tools are custom-designed to meet your bore diameter and length requirements.

Be it Single Tube, Double Tube, Gun Drilling, or other specialty drilling system, Sunnen has the engineering expertise and manufacturing capabilities to offer single source, turnkey solutions for your deep hole drilling applications.

The new Sunnen SHDD-series is designed around the BTA deep-hole drilling process in cylindrical parts. However, it is also capable of a wide variety of other similar machine processes, including counter boring, pull boring, trepanning, bottom forming, and skiving/roller burnishing.

Sunnen offers a tooling line to cover a range of diameters from 11.1 mm up to 65 mm (.437” to 2.559”).   DirectDex, TrueDex and FlexiDex are indexable drill head solutions, complete with cartridges, pads, inserts, shims, and screws.  Tool lines are designed to match the quality and range of common Sandvik drill heads.  We offer a comprehensive line of coatings for optimal cutting and tools life.  The combination of quality drill heads and consumables, provides additional cost saving for your drilling operations.

Gun drilling is the oldest and most widely used method of deep hole drilling employed by industry today. The drill or “gun drill” is generally a one-piece assembly consisting of a hollow cylindrical drill driver. Also, it is brazed to a V-shaped crimped tube and finally assembled to a brazed-on solid carbide drill head. Both the crimped drill shank and the brazed-on carbide drill head from a kidney-shaped cross-section. Whereby the open V-shaped section acts as a chip flute.

Sunnen`s basic honing machines can be found in thousands of tool rooms throughout the world. Machines in this category are well suited to the low volume production that is typically performed in tool rooms and repair departments.

Diamond Plated Super Mandrels -- Designed to provide a long-wearing guide shoe to increase mandrel life in many honing applications. Another advantage of Super Mandrels is faster stock removal in difficult materials. Extended Shank Mandrels -- Available for honing parts that are too long to be honed with a standard mandrel. Tandem "In-Line" Mandrels -- Sunnen honing units can be used to size two or more "in-line" or tandem bores in perfect alignment.
