PCD Reamer

Extreme Accuracy and Surface QualityDesigned for micron-level accuracy and ultra-low surface roughness down to Ra 0.1, supporting IT6 and higher precision hole requirements.
Long Tool Life and Efficient ProductionPCD hardness is 3-4 times higher than carbide. Tool life can exceed carbide solutions by more than 20 times while supporting high cutting speeds.
Preferred for Difficult MaterialsEngineered for high-silicon aluminum alloys, CFRP and other difficult-to-machine materials in automotive and aerospace manufacturing.

PCD Inserts

Ultra-Hard and Wear ResistantHardness up to 8000 HV, 8-12 times higher than carbide. In aluminum machining, tool life can increase by dozens or even hundreds of times.
Mirror Finish by TurningA very low friction coefficient reduces built-up edge and enables Ra 0.05-0.1 um mirror finishes, replacing grinding in suitable operations.
Grades Matched to ApplicationDiamond grain size is selected by material and finish target: fine grain for finishing and low-silicon aluminum, coarse grain for high-silicon aluminum above 12% Si.

PCD Milling Cutter

High Efficiency for AluminumDesigned for high-speed milling with cutting speeds up to 7000 m/min. In aluminum alloys, productivity can be up to 10 times higher than carbide tools.
Stable Precision MachiningMulti-flute cutting edge runout can be controlled within 0.002 mm, delivering Ra 0.6-1.2 um surface quality with sharp cutting edges.
Flexible Structures and One-Pass FormingAvailable as flat, ball nose, brazed, indexable or sintered structures. Custom form cutters can combine multiple operations into one pass.

Solid Carbide Drill

High-Precision DrillingDiameter tolerance can reach 0-0.03 mm. Self-centering geometry supports high-quality hole walls and IT7-IT12 tolerance ranges without secondary finishing.
Rigid Structure for Productive CuttingThe solid carbide body handles high cutting loads. With TiAlN and other advanced coatings, feed rates can reach 0.70 mm/rev and cutting speed up to 220 m/min.
Advanced Cooling for Deep HolesOptimized internal coolant channels improve heat control and chip evacuation, supporting deep-hole machining up to 50xD in suitable conditions.

Solid Carbide End Mill

High Precision and High RigiditySolid carbide rigidity exceeds HSS tools, with runout controllable within 10 um and even down to 3 um for precision and micro-part machining.
High-Performance Cutting GeometryTiAlN, AlTiN and other PVD coatings combine with unequal pitch and variable helix anti-vibration designs to raise metal removal rates.
Broad Material Coverage and RegrindingSuitable for steel, stainless steel, aluminum, titanium, heat-resistant alloys and hardened steel up to HRC 65, with regrinding to reduce long-term cost.

Solid Carbide Boring Tool

High Rigidity for Deep BoringSolid carbide bending rigidity is far higher than steel boring bars, reducing chatter and deflection for stable machining at 5xD or even 10xD overhang.
Micron Accuracy for Precision HolesMicro boring tools can be produced down to 0.6 mm or even 0.3 mm diameter, with finishing accuracy below 0.005 mm and surface roughness below Ra 0.4 um.
Coated, Stable and DurableTiAlN, Al2O3 and other advanced coatings support cutting speeds of 100-400 m/min. Internal coolant improves chip evacuation and process stability.

PCBN Boring Tool

Built for Hardened MaterialsPCBN cutting edges support consistent boring performance in hardened steel and other high-hardness workpiece materials.
Stable at Cutting TemperatureThe tool geometry is designed to maintain edge integrity under the heat generated by continuous finishing operations.
Repeatable Bore QualityControlled runout and rigid tool construction support repeatable diameter, roundness and surface-finish targets.

Custom Step Reamer

Coaxial Geometry ControlDatum strategy, guide sections and cutting-edge runout are matched to the component tolerance stack.
Application-Matched DesignDiameter, step length, coolant delivery and edge material are configured from the customer drawing and process.

Combination Drill-Reamer

Shorter Machining CycleDrilling, semi-finishing and reaming functions can be integrated to reduce non-cutting time and tool changes.
Aligned Cutting GeometryAll working diameters share one tool body to support positional and coaxial consistency through the full bore.
Directed Coolant DeliveryInternal coolant channels are positioned to cool the cutting edges and evacuate chips from deep features.

Custom Form Milling Cutter

Profile AccuracyThe cutting form is engineered from the finished component geometry and verified against the required profile tolerance.
Balanced for Production SpeedBody mass, tooth count and edge position are coordinated for stable cutting at the planned spindle speed.
Serviceable Tool ConstructionBrazed, indexable or replaceable-edge structures can be selected according to volume and maintenance requirements.

Multi-Diameter Boring Tool

Coaxial Bore ControlMultiple precision cutting positions are referenced from one body to reduce accumulated alignment error.
Guided Cutting StabilityGuide pads and support lands can be incorporated where long overhang or interrupted cuts demand added stability.
Repeatable AdjustmentFine adjustment and presetting features support controlled diameter correction during batch production.

Custom PCD Face Mill

High-Quality Flat SurfacesPCD edge geometry and controlled axial runout support low roughness and consistent flatness across wide faces.
High-Speed Aluminum CuttingA lightweight, balanced cutter body is configured for productive spindle speeds in aluminum applications.
Maintainable Edge SystemCartridge, adjustable or brazed-edge options can be selected around the required accuracy and service strategy.
