Tube Hollows International offers far more than precision deep hole drilling. We support our gun drilling expertise with additional in-house precision machining resources, including CNC and conventional precision milling. Milling is essential to the design and function of many precision components in the aerospace, medical, energy and industrial sectors, where engineers and designers routinely rely on complex, highly detailed dimensional parts with tight tolerances. CNC milling is the most common form of computer numerical control (CNC) machining. It performs the functions of both drilling and turning machines by creating precise 2D and 3D shapes, all while maintaining tolerances as tight as 0.0001 of an inch.

Tube Hollows International offers precision honing services to meet our customers varied seamless tubing and precision tubular component needs. Depending upon the alloy being machined, gun drilling generally leaves a burnished finish on the inside of a seamless tube that is finer than Ra 125. In some applications, this finish is acceptable or even preferable. However, in other applications, an even smoother finish is required to optimize the overall performance of the part. Tube Hollows Internationals machinists have the experience needed to efficiently drill a wide range of ID sizes to exacting dimensional, concentricity and finish specifications. Honing is a precision machining process which uses a variety of abrasives to remove small amounts of material from inside a seamless tube hollow. Honing is a lower velocity abrading process than grinding. Because less heat and pressure is created, the finish, size and precision of the final product is not affected by heat stress. Precision honed tubes feature excellent surface integrity and finish, precise inner diameter tolerances and an overall size and geometry control that cant be achieved at higher cutting speeds. Honing is a cost effective way to machine extruded tubing stock to the exact wall thickness and finish specified by our customers. This can contribute to project cost savings, especially when working with expensive metals such as titanium, Nitronic 50 and other specialty alloys. Instead of starting with a solid piece of barstock, Tube Hollows International can recondition an extruded seamless tube. Then, according to customer specifications, we can hone the tube to improve its finish and produce the exact bore size required. Tube Hollows International hones tubes with IDs .250" and larger. Our shop floor is equipped with multiple Sunnen hones to ensure consistent quality and capacity. Our expert machinists routinely produce finishes down to Ra 16 and finer. Honing minimally impacts wall thickness variation, concentricity or ID straightness. When larger amounts of material need to be removed or concentricity improved, other processes precede honing. Tube Hollows International combines trepanning, gun drilling, honing and other capabilities to produce tubular components and custom tubing at industry leading levels of precision. At Tube Hollows International, our experienced staff will help you determine which precision boring and tube conditioning service will produce the highest quality, most cost effective end product that will meet the rigorous quality controls and standards in the medical, aerospace, energy and industrial sectors.

Tube Hollows International is uniquely positioned to create precision tubular components by combining its world leading drilling capabilities with complementary machining services. We turn many precision parts, operating to extremely tight tolerances and precise diameters and depths. In particular, aerospace and industrial parts feature flanges, steps, chamfers and other features that require high end lathe work. Should your project require additional machining, our larger family of machine tools and processes makes Tube Hollows International an all-inclusive, one stop experience for all your seamless tubing and precision machining needs. CNC turning is a cost effective process for machining precision parts in a wide variety of profiles, including plain, contour and radius. CNC precision turning relies on a rotating drive which holds a cylindrical piece of metal firmly in place. The cutting tool then moves across 2 axes, producing precise depths and diameters in the finished product. Material removed from the cylinder as it rotates is turned into metal chips (also known as swarfs or turnings). The different types of turning operations include: Tapered Turning; Spherical Generation; Hard Turning; Face Grooving (similar to boring); Facing (cutting tools face the rotating material at a right angle); Knurling (used to form hand grips); Reaming (small, precise holes); Threading (for screws); and Polygonal Turning (for turning of noncircular shapes). When working with expensive, rare, or high end alloys such as titanium or 17-4 Stainless Steel, our experience and industry leading quality control standards set Tube Hollows International apart from our competitors. Although CNC turning machines are incredibly accurate, they must be operated by highly trained, experienced machinists. After all, even the highest tech machine is only as good as the person standing at the controls. When commissioning CNC turned parts from Tube Hollows International, you can rest assured, knowing our expert staff has extensive experience working with a wide array of exotic metals and alloys. Our expertise and companywide commitment to excellence will result in the highest quality end product.

Boring is the process of enlarging holes that have already been drilled, ensuring they are concentric and properly sized and finished post manufacturing. However, when working with intricately machined parts and costly, difficult to drill metals and alloys, boring becomes far more complex than the simple drilling of a hole. Based on our proven track record with deep hole drilling of seamless precision tubing, Tube Hollows International has expanded its gundrilling capabilities to support our customers varied engineering and manufacturing needs. We offer pattern drilling and step boring services performed with the same attention to quality control and industry leading tolerances to complement our gundrilling services. Tube Hollows International offers a variety of complex boring services, including: step boring, blind bottom boring, chamfering and complex pattern drilling. If your machined part or tubular component requires pattern drilling or another complex boring service, please contact one of our engineering consultants to see how our capabilities fit your projects unique design and manufacturing requirements.

MORE THAN A HALF-CENTURY OF EXACTING TOLERANCESIN PRECISION TUBULAR COMPONENTS precision machined partsAt Tube Hollows International, everything we do has grown out of our ability to drill precision holes to exacting tolerances in a range of specialty metals and alloys. Deep hole drilling is a specialized process used to generate holes with ratios typically greater than 20 times the drill diameter. THIs unique machining technology allows us to drill bars as long as 25 feet with exceptionally low drift, maintaining wall variations as low as 1% tolerances previously unachievable. The result: unmatched concentricity. Tube Hollows uses a borecentric approach to drilling. This ensures that customers who wish to machine a tight tolerance hole through a part with finished OD dimensions have a reliable, top quality solution available.

THI Uniwall Hollow Bar products are available in a wide range of sizes and alloys. We offer an industry leading standard wall variation of less than 3% in 17-4, 15-5, 316L materials and sizes ranging from 1 to 3. We can offer additional services to meet your needs as well, whether cutting, counter boring, threading, centerless grinding, and honing to name a few. Most products are available for quick shipment.
