The Materials used for manufacturing bearing rings are Alloy Steel, 52100 grade and are procured from the Steel Mills approved (ISMT, MUSCO & MUKAND) by SKF and FAG as per their specifications. We have state of the art, Metallurgical testing lab to carry out all kind of inspection of the materials received through the above mills. To ensure the desired quality and consistency we keep track of each and every lot of steel supply received at our end.
Forging is the process of converting the round bar raw material into the desired shape and size to make the parts as per the specified drawings of the client. The hot cut pieces are pressed, punched and pierced to put through rolling into the required size. All forging press lines are highly flexible, which gives the company the inherent advantage to simultaneously meet different customer demands and optimize capacity utilization.
Computerized Pit Type Electric Annealing Furnace
Sphereodize annealing is process to improve machinability of hypereutectoid steel. This process will change the spheroidal or globular form of carbide in a ferritic matrix which makes the machining easy. The process is called Spheroidizing. The benefits of a Sphereodize annealing are: Improved ductility, Removal of residual stresses that result from cold working or machining, Grain refinement. Annealing reduces the hardness; yield strength and tensile strength of the steel.
CNC (Computer Numerical Controlled) Machining
The machine shop at Ravi Technoforge has inbuilt versatile capacities. We have installed a series of best of the breed CNC turning machines to maintain quality, accuracy and productivity. Our state-of-the-art machining facility is the largest of its kind and added to this are our flawless Inspection and Testing facility that further take manufacturing standards to levels of excellence.
Crack Detector Machine and Steel Grade Sorting machine
Crack detector machine are for to check any possible crack within the forged part. We do cent per cent MPI test on all forged products. The experienced manpower in the processing division is qualified for MPI- Level II certification. Steel grade sorting is carried out to remove any possible mixing of materials during stacking of RM or at forging shop. During this operation any material mixed up other than the specified material is identified and removed from the forged parts.
Quality – Physical Inspection
Inspections of pre-turned races are done randomly and continuous dimension inspection is done during turning process. 100% Crack Detection testing, 100% Visual inspection for dent, forging sports, rust & Burr of turned races is done.
Quality – Laboratory Inspection
Ravi Technoforge strives continuously to improve its Quality standards to satisfy the need & expectations of the customers by establishing effective process control & Prevention Techniques and by supplying quality assured goods on time. The tests are conducted as per I.S. & A.S.T.M. standards in the Laboratory, such as Chemical Composition, Inclusion Rating, Carbide, Grain Size and other tests.
Over last 2 decades Ravi Technoforge Pvt. Ltd has expertise the art of manufacturing high quality rings. The rings include Ball bearings, tapered, spherical and cylindrical rings. In addition to this the rings manufactured at Ravi Technoforge's state-of-art production facility is capable of producing Railway bearing components and spacers with operations of drilling, turning and marking. Ravi Technoforge's expertise lies in grasping the exact requirement of the client and exceeding the expectations by producing products that exactly suit customer needs.
