Adopting advanced power high speed CNC grinder from Germany and Switzerland as well as high precision (3DX technology) grinding of high

High-impact-resistant diamond tungsten steel (for intermittent cutting)

High hardness diamond tungsten steel (for high wear resistance) HRF10/SR10T

Tungsten steel meeting ISO standard (for general machining) PR40/PRA5

High cobalt HSCo8(SKH59), ASP60 German standard (DIN) series complete grinding (2-flute~6-flute) end milling，

(2-flute~4-flute) ball milling

Type of flute:

(standard and non-standard 1-flute~12-flute series mill, reamer): deep groove, round head, end angle R, hollow, oblique flute (tapered), long flute, for aluminum, copper application, chip-dividing groove (for rough mill application)

MRll diameter:

(miniature) φ0.10mm---φ53.00mm (solid tungsten steel), φ20.00mm--φ80.00mm (brazing)

Tolerance:

(standard and non-standard) tolerance of flute diameter of diamond tungsten steel can be up to ±0.001mm (±1μm) high, and tolerance of holder diameter is more than h6.

Helical angle: 0°,25°,30°,35°,45°,50°,55°,60°

Cold-hard machining replacing grinding can improve precision, hard milling replacing grinding can improve efficiency。

(Non-coated diamond steel tooling for high hardness steel machining can replace TiALN coated ultra micro-grain carbide, ceramics. After cutting, CBN tooling has excellent smoothness and lower tooling cost.)

Miniature and profile compound tooling can be machined according to drawing or sample

When placing an order, please indicate: name (flute type) ＊ number of flute ＊ flute diameter ＊ flute length ＊ holder diameter ＊overall length＊type of shank＊ (inclination) ＊ helical angle ＊ required tolerance

HRF10
ultra micro-grain quality carbide, has excellent wear resistance, but its impact resistance is not so good. It is applicable for medium and low speed cutting of high hardness materials(HRC45°-65°) requiring thermal refining and quenching or for various materials having higher wear resistance and non-ferrous metal. Generally it is applied in good working condition\stable cutting\excellent part fixing and continuous light machining. Corresponding to ISO K10.

PR40：

super micro-grain diamond tungsten steel, extensively applied, it can be applied in medium speed cutting and finish cutting of various materials with HRC≤28°. It has excellent impact resistance and general wear resistance, and has extensive application. Generally, it is applied for thicker cutting, discontinuous cutting and bad part fixture. After being coated, it has better result, can machine various materials of HRC50°. Comparing with ISOK20&general tungsten steel, it has 1-2 times lifetime and excellent wear resistance

From high-class products (via 6-axis/ 7-axis Blocking CNC-machine Tool (Class-AAA)) to medium-class products (via 3-axis/ 4-axis Blocking CNC-machine Tool (Class-D)), different quality and price, our reliable products can replace to first-class products, and we are professional in wholesale, R&D, producing & processing, as well as design revision according to client's designs and samples of special, non-standard, abnormal shape and new products with high cost-performance ratio, also our on-demand service will decrease your comprehensive cost greatly!

Referencing to the page footer, please provide your sample and specify the detailed specification, material type, size tolerance, drawing of semi-product and finished product, applied equipment, equipment value (RMB, to judge its market value  is rigid or floating), monthly consumed quantity, type of original product and its deficiency, when you make inquiry. What is the processed material and its HRC? Work piece drawing and notes, and please supply us new and old bestperformed samples.
