BB SDJ Boring Cutter

Reduce machining process, improve efficiency, reduce boring time.

Abandoning the structure that the hole shaft gap of the fine-tuning structure after the locking of the traditional fine-boring tool can not be eliminated, the unique chute coupling principle is adopted, all accessories are tightly fitted, and the locking screw is not in contact with the fine-tuning mechanism, so as to achieve large margin cutting and precise fine-tuning, so that the boring efficiency is increased by more than twice, and the blade loss is reduced by more than 5 times, and the stability is improved.

Comprehensive Upgrade By Comparison, we Can See

SDJ precision boring cutter
Single side cutting volume 0.8mm large cutting
Coarse and fine two-layer adjustment scale is fast to fine
Adjusting a little bit into a little bit without turning around
Fine adjustment accuracy=0.005mm

Old single blade precision boring cutter

Single side cutting amount 01-02mm
Need to constantly twist the adjusting disc to
damage the screw rod
Each adjustment requires one turn to eliminate the gap
Fine adjustment accuracy=001mm

Unilateral Cutting Amount 0.8，Fast and Large Allowance Cutting

Bottom Hole 50
Diameter After Boring 51.6
Unilateral Cutting Amount0.8mm
Bottom Hole 50
Diameter After Boring 50.4,Unilateral Cutting Amount 0.1-0.2mm

Deep Boring Without Vibration Tool,(Hole Depth=Diameter X8)

Good smoothness The workpiece is printed with a human figure
After the SDJ precision boring tool is processed, the product has
good smoothness and the boring wall finish is close to the mirror surface

Chute Type Coupling DesignAdjust a Little Bit Into a Little Bit

This product abandons the structure of traditional precision boring cutters that cannot eliminate the gap between the hole and shaft after fine adjustment after locking. It adopts a unique sliding groove coupling design principle, allowing all accessories of the cutter body to tightly fit after locking, and the locking screw does not come into contact with the fine adjustment structure, thus truly achieving a professional precision boring cutter that adjusts one thread into one thread

Quick and Accurate Fine-Tuning Reduce Screw Wear

The coarse and fine fine fine adjustment scales have two layers, ranging from fast adjustment to accurate fine adjustment operation. Compared to traditional precision boring cutters, the SDJ precision boring cutter has a shorter adjustment time, and can be easily adjusted by loosening, pushing, rotating, and fixing, reducing the wear caused by multiple rotations and twists of the screw rod

01/Pine
Use a wrench to turn the top screw to loosen it
02/Push
Push the top slider to quickly adjust the scale of the coarse boring cutter
Reduce screw wear
03/Rotate
Rotate the precision boring scale compass on the side for small adjustments and long service life
Less adjustment times compared to
traditional boring cutters
04/Fixed
Easy and accurate adjustment through four steps of loosening, pushing, rotating, and fixing

Handling Processing Issues We Are More Professional

Common Processing Issues
Poor Precision Machining Issues
Water ripple pattern, radial pattern, fish scale pattern, and loud processing noise
Effective Improvement Measures/Reasons
① Confirm that the rounded corner of the tool tip is at angle 02 and the margin on one side is between 01 and 0.15
② Reduce drilling speed or increase feed rate
③ Reduce the length of the prop (effective depth)
④ Insufficient rigidity of the machine tool or excessive tool weight
Poor Precision Machining Issues
Irregular circular texture and low processing noise
① Ditto
② Increase speed or decrease feed rate
Poor Precision Machining Issues
Reduced size during porous processing
Effective Improvement Measures/Reasons
① Reduce speed, maintain or increase feed rate
② Replace the blade with a suitable material
③ Confirm that the margin is between unilateral 01 and 0.15
Poor Precision Machining Issues
Unexpected cone hole occurs
Effective Improvement Measures/Reasons
① Confirm that the margin is between unilateral 01 and 0.15
② Confirm that the tool tip is 0.2 rounded corners
③ Reduce feed rate or increase speed

Maintenance Manual Tips for Extending Tool Life

CNC Tool Handle/Chuck Maintenance
Most CNC tools will rust, and tool maintenance is of great significance for extending their service life. Maintenance should start from the following four aspects
Antirust oil—–Wipe the tool dry Clean application of anti rust oil
Desiccation—–Dry environment makes it easier to store
Anti Collision—–Classification and placement of metal objects
Corrosion Prevention——Prohibit contact with
Corrosive liquids

Hard Alloy Blade Maintenance
When purchasing hard alloy blades, merchants will ship them in the form of storage boxes. To store the blades, they should be placed in a small compartment inside the box, without the need to apply rust preventive oil. Do not mix different blades for storage.

Maintenance of Milling Cutters and Drill Bits

The sharpness of the milling cutter blade directly determines its processing quality, so it is important to focus on protecting the cutting edge. Prevent collisions with other metal objects or falling to the ground. When not in use, it should be stored in a storage box or tool holder and placed separately.

Boring Tool Maintenance

When adjusting the boring range, it is necessary to check whether the side fixed locking screws are loose. Forcibly adjusting the boring range while tightening the tightening screws can damage the accuracy of the boring tool.
