Precision machining is the process of cutting metal parts to make them fit today’s modern technologies. Impro specializes in hydraulic spools, pistons, engine fuel injectors, and assemblies using computer numerically controlled CNC machines and other tools. Our products are used across industries such as automotive, hydraulics, medical, and oil and gas. We excel in offering one-stop solutions to our global customer base.
Details about Precision Machining
To ensure the highest quality of the finished products, the use of computer programs is critical. CAD (Computer Aided Design) and CAM (Computer Aided Manufacturing) programs provide detailed blueprints about each step of the precision machining process. Programs like ProE and UG create extremely detailed three-dimensional blueprints. Precision machining can be used on many materials, including steel, aluminum, copper, bronze, and some special alloys.
Impro’s Precision Machining
Impro’s dedication to the precision machining process is extensive. We pride ourselves on our high-quality products and services, reasonable costs, and timely delivery of all our products. We hold quality certifications according to ISO 9001, ISO/TS 16949, ISO14001, and BS OHSAS 18001. We take orders for just a few pieces or up to several million. We are known for our specialization in steel alloys, stainless steel, and carbon steel for various markets.
Types of Machining Processes
Impro uses a multitude of special machining processes:
- Precision Honing: This process uses honing hole diameters ranging from 0.8mm to 100 mm and has depth up to 280 mm. The linear tolerance is 0.001 mm, roundness of 0.0005mm, and straightness of 0.0005 mm. The surface finish is Ra0.05μm. Horizontal and vertical honing machines are used and include single-spindle, twin-spindle, and six-spindle.
- Hard Turning: This is the process of single point cutting of hardened pieces. Our hard turning process can machine parts with hardness over 58 HRC after heat treatment, maximum turning diameter of 26 mm, turning length up to 100 mm, dimensional tolerance of 0.005 mm, and roughness Ra0.2μm.
- High Precision I.D. and O.D. Grinding: This process enables us to machine shafts with diameter with 750 mm, length within 1000 mm, roundness of 0.0004 mm, and cylindricity of 0.001 mm. The inner holes range from 3 mm to 100 mm.
- Deburring: Impro’s deburring capabilities include electrochemical machining, thermal energy method, and abrasive flow machining. These are used for hydraulic, automotive, and aerospace components with crossing holes and complex inner cavity to meet strict deburring requirements.
- High Precision O.D. Centerless Grinding: This is used for shafts with diameter with 200 mm, length with 400 mm, diameter tolerance of 0.001 mm, cylindricity of up to 0.0005 mm. It is available for both through-feed and infeed.
- Heat Treatment: Impro prides itself on our eight multi-purpose production lines with maximum temperature of 950℃, four vacuum furnaces with maximum temperature of 1320℃, five freezers (-190℃), nitriding and nitrocarburizing well-type nitriding furnaces, and two high-frequency quenching furnaces with case depth ranging from 0.5 mm to 4 mm.
At Impro, we pride ourselves on reliability, flexibility, and globalization. Our experts oversee the production process from start to finish. We offer one-stop solutions to our customers from design to production, heat treatment, surface treatment, and shipping and logistics. We also offer component assembly if required. Our clients globally and nationwide rely on us for concurrent design and engineering support, and materials and manufacturing support concerning properties and specifications. We have in-house rapid prototyping capabilities and in-house material testing, NDT, welding, and heat treatment.
