Our factory specializes in manufacturing high-precision boring
bars, core precision tool accessories for CNC machining centers,
lathes, milling machines, boring machines and deep hole processing
equipment. They are mainly used for precision internal boring, deep
hole machining, aperture correction and finish boring & milling
operations, widely applied in industries including machinery molds,
hardware processing, auto parts, aerospace components, woodworking
machinery and automated equipment part manufacturing.
As critical components for deep hole finishing, the rigidity,
straightness and stability of boring bars directly determine the
internal hole precision, surface finish and coaxiality of
workpieces, making them indispensable core parts for high-precision
hole machining.
Our boring bars are elaborately fabricated from premium high-grade
materials such as 40Cr alloy steel, tungsten carbide alloy,
high-speed steel and cemented carbide. The raw materials feature
high density, sufficient toughness and ultra-high rigidity with
outstanding bending resistance, vibration resistance and fracture
resistance.
Each product goes through multiple precise manufacturing processes:
integral quenching and tempering heat treatment, precision finish
turning, high-precision cylindrical grinding, straightening
correction and dynamic balance calibration. These procedures
completely eliminate internal material stress and prevent bending,
chatter and deflection during long-hour machining.
The boring bars boast superior overall straightness, precise
concentricity and excellent surface finish. No tool chatter or
vibration occurs during deep hole machining, effectively
eliminating processing defects such as internal hole ripples, taper
and inconsistent bore size deviation.
Our full range of boring bars are suitable for various machining
scenarios including fine boring, rough boring, deep hole boring,
through-hole and blind-hole machining, meeting the demands of
continuous high-precision, high-speed and long-stroke processing.
They feature wear resistance, high temperature resistance, stable
cutting performance and long service life.
We offer customized types per customers’ equipment requirements:
solid boring bars, hollow boring bars, extended-length boring bars,
anti-vibration boring bars and cemented carbide boring bars.
Customization of non-standard diameter, overall length, cutting
edge length, connecting thread positions and mounting structures is
available.
As an original manufacturer integrating production and sales, we
implement strict full-process quality inspection. Standard
specifications are kept in abundant stock with stable lead times.
We accept bulk orders and rush custom orders, serving as an ideal
supplier for machinery processing factories and equipment
supporting manufacturers.
