At our machining workshop, we specialize in a wide range of precision machining processes and work with an extensive variety of metals and alloys. Our goal is to provide high-quality components that meet the strictest industry standards for our clients in the automotive, aerospace, hydraulics, and other sectors.
We have the expertise to machine a comprehensive selection of materials, including both standard and specialty grades. Our capabilities cover:
Cast Irons: Gray Cast Iron and Ductile Cast Iron.
Carbon Steels: From low to medium and high carbon steel grades.
Alloy Steels: We work with standard grades and can source special grades upon request.
Stainless Steels: Including standard Stainless Steel and Duplex Stainless Steel.
Specialty Steels: Such as wear-resistant, corrosion-resistant, and heat-resistant steel.
Non-Ferrous Metals: Aluminum, Zinc, Brass, and Copper alloys.
Forgings & Profiles: We also machine alloy forgings, as well as steel and aluminum profiles.
Our state-of-the-art facility is equipped with a full suite of machining processes to handle complex and intricate part geometries. Our capabilities include:
We offer precision turning for parts with diameters up to 26 mm and lengths up to 100 mm. Our hard turning process can machine materials with a hardness exceeding 58 HRC after heat treatment, achieving a dimensional tolerance of 0.005 mm and a surface roughness of Ra 0.2 µm.
We provide both internal (I.D.) and external (O.D.) grinding services. We can precision-grind shafts with a diameter of up to 750 mm and a length of 1000 mm, achieving a roundness of 0.0004 mm and cylindricity of 0.001 mm. Our I.D. grinding capabilities cover holes ranging from 3 mm to 100 mm.
Our O.D. centerless grinding capabilities are ideal for high-volume production of shafts. We can handle shafts with a diameter up to 200 mm and a length up to 400 mm, achieving a diameter tolerance of 0.001 mm and a cylindricity of up to 0.0005 mm. We offer both through-feed and in-feed grinding methods.
We use both horizontal and vertical honing machines, including single, twin, and six-spindle configurations. Our honing capabilities cover hole diameters from 0.8 mm to 100 mm with a depth up to 280 mm. We achieve exceptional precision with a linear tolerance of 0.001 mm, a roundness of 0.0005 mm, and a straightness of 0.0005 mm, resulting in a surface finish of Ra 0.05 µm.
To meet the strict requirements of hydraulic, automotive, and aerospace components with complex geometries and crossing holes, we offer advanced deburring services. Our processes include electrochemical machining, thermal energy method (TEM), and abrasive flow machining.
In addition to the specialized services above, we are also proficient in a wide range of standard machining operations, including Milling, Drilling, Boring, Facing, Planning, Shaping, Grooving, Threading, Tapping, Lapping, and Gear Hobbing.
