IMPROVING BORE QUALITY WITH SKIVING AND ROLLER BURNISHING

skiving and burnishing tool

Skiving and roller burnishing is one of the most surprisingly productive ways to achieve high-quality bore finishing in OEM production. Even experienced machinists are impressed when they see raw tubing converted into a mirror-like finish in a single pass at extremely high feed rates. This is achieved by combining two operations into a single tool and having the right machine for the job.

The process works by using a set of floating knives on the front of the tool, followed by rollers. The diameter and finish are adjustable on the head to “dial” in the exact sizes, and the finish can be tuned by adjusting the roller pressure relative to the cutting diameter. Cutting fluid floods the tool to clear chips, and hydraulic actuation protects the finished surface as the tool retracts. The process delivers outstanding accuracy, surface durability, and repeatability across a wide range of bore sizes and production environments.

ACHIEVABLE RESULTS

The result is a highly efficient method that routinely achieves:

  • Cutting speeds up to 300 m/min (1000 SFM)
  • Feed per revolution 3 mm/rev (0.118 IPR)
  • Feed rates over 4000 mm/min (157 IPM)
  • Surface roughness Ra in the 0.2-micro-meter (8-micro-inch) range
  • Circular form as close as 0.01mm (.0004 inch)
  • Diameter tolerance IT8 – IT9

These capabilities significantly enhance surface durability, a crucial factor in hydraulic cylinder manufacturing and other critical applications.

Skiving Burnishing Machine

APPLICATION AND PRODUCTION FLEXIBILITY

The process applies across a wide range of bore sizes and depths, from 30 to 500 mm (1.18 to 20 inches) and beyond 6 meters (20 feet). UNISIG has applied this method to depths over 13 meters (43 feet) in demanding oil and gas environments.

Most applications remove a small amount of material efficiently, typically around 1.5 mm (0.06 inches). When rough tubes require more cutting, a combined counterbore-skive-burnish tool may be used. Shorter parts can be processed vertically with separate skiving and burnishing tools, which simplifies setup and increases automation opportunities.

UNISIG MACHINES BUILT FOR THE PROCESS

Skiving and roller burnishing places significant demands on the machine platform, often requiring more than 100 kW (134 hp) at the tool. UNISIG machines are engineered to meet these requirements with power, rigidity, and long-term reliability.

  • S-Series machines are purpose-built for tube production, designed specifically around the skiving and roller burnishing process. Robot-ready configurations are available as a standard option.
  • B-Series BTA deep hole drilling machines support both the creation of the starting bore and the final high-quality finish, offering manufacturers a single platform for multiple operations.

Although skiving and roller burnishing is not as common as conventional drilling, milling, or turning, it is a proven method to drastically increase productivity and quality. These machine platforms allow manufacturers to fully leverage the productivity and quality advantages in high-volume production environments.

SMART SYSTEMS THAT CONSERVE ENERGY

Variable Delivery Coolant Pumps: Deep hole drilling relies on cutting fluid at high pressures and flow rates to achieve accurate holes and reliable chip evacuation. If you are unsure how much is needed, you often apply too much, wasting energy in the process. Low-technology pumps rely on relief valves to regulate pressure, effectively functioning as heaters that never turn off. UNISIG high-pressure coolant pumps use variable speed drives and other variable volume delivery techniques to supply the exact amount of cutting fluid for the process, saving energy every minute the machines operate.

Regenerative Electrical Drives: When decelerating a load, the kinetic energy from moving mass must go somewhere. It can either be unloaded as heat into the braking system or conserved and reused. UNISIG uses regenerative drives for complex motion systems to conserve energy and improve dynamic performance. The motors paired with these high-technology drives offer exceptional efficiency and high power density. In many machine builds, UNISIG also employs drive systems (active line modules and active interface modules) with power factor correction and additional components to reduce electromagnetic interference, returning high-quality power to the grid.

LED Lighting: Machine enclosures are brightly lit to improve operator visibility during setup and prevent costly mistakes. UNISIG uses LED lighting, which consumes less energy and lasts longer than traditional lighting.

Sleep Modes: When idle, control systems automatically shut down transfer pumps and power units to conserve energy. Pneumatics are also turned off to prevent the use of unnecessary compressed air.

COMMITMENT BUILT INTO EVERY MACHINE

Energy efficiency is not a separate feature; it is built into every decision we make. Our repeat customers recognize the performance, precision, and service that define UNISIG, and our energy-efficient designs are simply part of the package. Thoughtful engineering, modern systems, and smarter power use all contribute to machines that run better, last longer, and deliver more value over their lifetime.

Trepanning is a process used to create a hole in a workpiece by machining only the outer area of the hole, leaving an unmachined core in the center. A BTA drill creates the same hole by turning all of the material into chips, leaving no core behind. This gives manufacturers two distinct ways to create a hole from solid material.

WHEN IS TREPANNING THE RIGHT CHOICE?

oil field manufacturing application example

Trepanning is a process that creates a hole in a workpiece by machining only the outer area of the hole, leaving an unmachined core in the center. In contrast, a BTA drill creates the same hole by turning all of the material into chips, leaving no core behind. This provides manufacturers with two distinct ways to create a hole from solid material.

BTA drilling is simple in concept: set up the machine, drill the hole, remove the workpiece, and empty the chip hopper when it’s full. Many manufacturers choose this process for its straightforward operation and the convenience of chip recycling. Trepanning isn’t necessarily more difficult, but it requires more operator involvement. When the hole is complete, the retained core must be removed from the tool between cycles.

Trepanning and BTA solid drilling share the same coolant delivery and chip evacuation systems. Coolant is introduced around the outside of the tool, and chips are exhausted through the drill tube. In BTA drilling, coolant passes freely through the tube, carrying chips to the conveyor. In trepanning, however, chips taken by the coolant must pass by the workpiece core inside the tube. The bore quality between the two methods can be similar, but it depends on the tool design. Trepanning tools with a sufficient cutting width to engage guide pads can achieve diameter tolerances similar to solid drilling. Tools designed for the narrowest width of cut (leaving the largest core) generally produce lower bore quality. For very deep holes, a counter-rotating tool and workpiece are often used. Because the trepanning core rotates with the workpiece, it can create challenges related to vibration or unexpected loading. Once these differences are understood, the key question becomes: When is trepanning the right choice?

ADVANTAGES OF TREPANNING

Saving the Core: One of the most significant advantages of trepanning is the ability to retain the core. The core may hold value for quality inspection or certification of critical parts. Because it originates from the same piece of raw material as the finished component, metallurgical samples can be documented or kept as a coupon for future evaluation if a finished part fails. In some cases, the core can be repurposed as a smaller workpiece, offering an economic advantage. Depending on size and material, the scrap value of the core may even exceed that of chips created through solid drilling.

Less Power for Machining (Sometimes): When the center of the workpiece isn’t machined away, machining forces can be reduced compared to solid drilling. This advantage is most evident when the tool is cutting a narrow width relative to the hole size and the depth isn’t great enough for the core to bend or rub inside the drill tube, which would otherwise create friction and require more power.

Better Economics in Tooling: Since trepanning does not machine the hole center, a center carbide insert isn’t required, and in some cases, the intermediate insert can also be eliminated. This can lead to significant tooling cost savings in production environments.

“Trepanning is not just an alternative to BTA drilling—it’s a strategic choice when core recovery, power efficiency, or tooling economy align with production goals.”

LIMITATIONS AND CONSIDERATIONS

Core Management: Managing and removing the core can be challenging, especially in long workpieces. The end face of the core typically has a sharp, blade-like edge from the final cut. Operators should be properly trained and handle the cores carefully to avoid injury, and the cores must be safely managed as they move through the plant after drilling. The tool head can also be damaged during core removal. Carbide inserts and cartridges should be inspected after each cycle to ensure they are ready for the next workpiece.

Cutting Insert Changes During the Cut: If a cutting insert dulls during trepanning, it’s difficult to index the insert mid-cycle. The tool must be retracted, often with the core still in contact with the inserts that were cutting it. In contrast, a solid-drilled hole allows the tool to be backed out, inserts replaced, and drilling resumed more easily.

Blind Holes: When a hole extends completely through the part, trepanning is straightforward to implement. When a hole is blind—only partially into the workpiece—the core remains attached at the bottom. Special core-breaking strategies or core-cropping tools can separate the core, but these add process complexity.

Chip Clearance Between Core and Drill Tube: The trepanning process leaves a core in the center of the drill tube while producing the hole, which has to compete for space with the chips exiting through the tool. Chip control is crucial, as is managing the wall thickness of the drill tube to ensure compatibility with the trepanning head, targeted hole size, and cutting width.

EQUIPMENT FOR TREPANNING

Many older trepanning machines were designed around lower power requirements and may not be suitable for modern BTA solid drilling. Likewise, trepanning tools designed for high penetration rates or small cores can stress older machines not built for that level of performance. UNISIG B-Series machines are designed to support both trepanning and BTA solid drilling. This gives manufacturers flexibility to choose the process that best fits their production goals—whether prioritizing material recovery, process efficiency, or overall machine utilization.
