OPERATING PRINCIPLE

How Does the UBURR Work?

The replaceable blade is controlled by spring tension. The blade automatically retracts while passing through the pilot hole and returns to the cutting position when it exits the opposite side.

Front-Side Deburring

On entry, spring tension holds the blade in the extended cutting position, removing the burr from the front side of the pilot hole.

UBURR blade retracting through pilot hole

Automatic Retraction

Increased feed pressure overcomes the preset spring tension and retracts the blade while it passes through the bore. Blade geometry protects the bore surface.

Back-Side Deburring

After exiting the pilot hole, the spring extends the blade again. The return stroke removes the burr from the rear side.

UBURR Product Recommendation

Tool Holder / Blade / Complete Set

Enter thread or pilot

Tool Holder—Enter a screw thread to select the holder directly, or use the pilot-hole diameter. The pilot-hole diameter is also used automatically for RPM and feed-rate calculation.

Recommended Blade—Blade recommendation follows the selected blade configuration and source chip-former.

Complete Set—Standard set includes the matching uncoated HSS P-chip-former blade.

Choose the tool by screw thread or pilot-hole diameter. For RPM and feed-rate calculation, the advisor uses the exact pilot-hole diameter; when a mapped thread pre-drill is available, it is inserted automatically. The complete set is supplied with the standard uncoated blade; alternative coated or carbide blades are ordered separately.

Calculated Machine Values

Derived from selected source ranges

Spindle SpeedEnter pilot-hole diameter

Feed RateEnter pilot-hole diameter

Machine max spindle speedRPMOptional. When the calculated speed is higher than your machine allows, the advisor caps it and recalculates the feed rate.

Starting-point guidance: For moderate tool-holder or workpiece stability, the source recommends reducing feed rates by up to 10%. For poor stability, it advises decreasing feed rates by up to 30%. Ensure appropriate coolant media is directed to the blade cutting tip and use right-hand machining (clockwise).

All 43 material conditions and source-table values are embedded in this app.

MACHINING LIMITS

Inclined Surfaces, Tubes & Coolant Direction

Sloped and cylindrical surfaces change the contact geometry of the blade. Verify the application before machining; an uneven chamfer is expected on non-perpendicular surfaces.

Rotation & Coolant

Use right-hand machining with clockwise rotation. Direct external coolant or air toward the blade to evacuate chips and swarf from the cutting zone.

Inclined Surface

The allowable slope depends on pilot-hole diameter and application geometry.

PORTABLE USE

Using the UBURR with Electric Hand Drills

UBURR is compatible with both CNC machines and electric hand drills, making it suitable for various operational setups and helping extend the tool’s usefulness beyond fixed machine applications.

PRACTICAL GUIDELINES

Recommended Setup Approach

When using portable equipment, prioritize stability, alignment and controlled feed pressure. The same cutting principles remain valid: clockwise rotation, proper chip evacuation, and a stable approach through the pilot hole.

Secure the Workpiece Clamp the part securely before deburring. Portable tools amplify hand movement, so workholding is critical for consistency.

Keep Straight Alignment Enter the pilot hole as straight as possible to reduce uneven chamfering and prevent unnecessary blade loading.

Use Clockwise Rotation Operate in right-hand machining direction and clear chips from the cutting zone using air or coolant when possible.

Start Conservatively Begin with moderate speed and feed pressure, then fine-tune based on chamfer size, burr condition and tool stability.

CNC PROGRAMMING

UBURR Programming Guidelines

Choose the required deburring cycle, review the actual tool movement, then load the corresponding macro inputs. The visual sequences below make the difference between front-and-back, back-only and interpolation programming much easier to understand.

UBURR front and back deburring six-step programming sequence

STANDARD CYCLE

Front + Back Deburring

Insert the rotating UBURR through the pilot hole. The blade cuts the front edge, retracts through the bore, extends after exiting, and deburrs the rear edge during the return stroke.

Key positioning: use H1 together with LTB1 and LTB2 from the holder table to place the cutting edge correctly at both sides of the workpiece.

BACK EDGE ONLY

Back Deburring Only

When front deburring is unnecessary, enter the pilot hole without spindle rotation. Start the working cycle only after the tool passes through the bore, then retract to machine the rear edge.

Important: spindle rotation remains OFF during entry through the pilot hole and is started only after the tool reaches the back-side position.

INTERPOLATION

Deburring by Interpolation

Use interpolation when the process benefits from combining deburring functions into one tool and reducing additional tooling. Program the toolpath to follow the required edge while maintaining proper blade engagement.

Use when appropriate: verify collision clearance and machine motion before production because the tool is no longer following a simple straight-through cycle.

Before production: verify tool length compensation, spindle direction, safe approach / retract positions, coordinate direction, workpiece clearance and the actual machine control syntax. Simulate or dry-run the cycle before cutting the first part.

EDGE SIZE CONTROL

Controlling the Chamfer Size

UBURR is primarily a deburring tool. The resulting edge break depends on tool selection, pilot-hole position within the holder range and working feed.

UBURR tool selection effect on chamfer size

Typical Chamfer The typical resulting chamfer is approximately 0.2–0.5 mm (0.008–0.020″), depending on the application.

Pilot Diameter Effect A pilot diameter closer to the minimum diameter of the selected holder generally produces a larger chamfer. A diameter closer to the upper limit produces a smaller one. The illustration shows this tool-selection relationship visually.

Feed Effect Increasing the working feed tends to reduce chamfer size; reducing the working feed tends to increase it. Optimize carefully while monitoring blade load and edge quality.
