Upon receiving the raw material, we proceed to perform wire drawing.Prior to usage, all the raw material is subjected to rigorous testing to ensure it meets the metallurgical, chemical, and physical specifications. Our raw material procurement strategy involves planning for a range of diameters, allowing us to cater to any possible bearing rollers requirement with ease. Given the fundamental role played by raw material in determining the final product, we place a premium on planning and have honed our skills in this area to a high degree. Following the annealing and wire drawing processes, we then inspect the annealing structure and HRB to ensure that they meet our exacting standards. For Annealing process we are using sequence bell type furnace For draw process we are using Wire draw machine , ludhiana make.
We produce all of our forging tooling by using RAWNE MAKE WPS D 2 and maintain our machines in-house. Our arsenal of tools and equipment includes CNC machines, VMC machines, bore grinding machines, OD grinding machines, and surface grinding machines, all of which are capable of producing top-quality tools and dies. By relying on our in-house capabilities, we are able to exercise precise control over the tools and equipment needed to produce each roller to its exact specifications.
The cold forging process, also known as ‘heading’, is utilized to achieve a near-net shape, thereby controlling scrap. Our machines are capable of forging a range of diameters, from 6mm to 28 mm , using different machines, including the polishing, H mann,that we have installed.
Rollers are indisputably the most vital component of a bearing, with the bearing’s overall performance being highly dependent on the physical and metallurgical properties of the rollers. To meet these stringent requirements, our heat treatment plant has a monthly capacity of 80 metric tons . Our skilled team of metallurgical and heat treatment experts ensures regular activity and product analysis through the creation of samples and microscopic examinations of each lot. To facilitate this process, we have a cutting, polishing molding machine .
in place to ensure prompt and precise sample preparation for examination under a OLYMPUS MAKE microscope, yielding accurate results.
The production of a precision roller involves subjecting it to multiple grinding processes across different types of machines, such as centerless grinding machines and duplex grinding machines. These processes are crucial as they transform the raw material into a precision roller. To ensure that we achieve the desired outcomes, we have installed some of the world’s best machinery, including , WMW, Scarlo, Pariwartan. In addition, we understand the significance of coolant filtration in achieving optimal grinding efficiency, which is why we have installed a filtration plant to ensure the highest quality output.
Super finish is the final process which is carried out as per the customer’s requirement of profile, roughness, Rt, Rz, cylindricity & roundness. Machines are installed to get the best results. All parameters are checked on high precision measuring instruments & calibrators.
For achieving Ra we have facilities of Vibro finishing m/cs
At Macwell Industries, we hold ourselves to a high standard of quality, which is evident in our quality inspection lab. We conduct in-process and random checks to ensure that our rollers meet the highest standards of quality. These checks include but are not limited to roughness, form error, roundness, OD radius, and microstructure checks. To ensure that our inspections are accurate and precise, we have a well-equipped lab that includes advanced tools such as Mitutoyo surftest, Olympus microscope, Mitutoyo roundtest, and hardness tester, among others. This allows us to maintain our commitment to delivering rollers that meet or exceed our customers’ expectations.

At Macwell, we are committed to providing zero-defect quality rollers to our customers. To ensure this, we conduct 100% visual inspections on all our rollers. Our visual inspection team is highly trained and skilled, and they are dedicated to ensuring that every roller meets the highest standards of quality. We regularly carry out cross-checks and verification of each team member to ensure that they have the necessary skills and capabilities to carry out the inspection process accurately and efficiently. This helps us to maintain our commitment to delivering rollers of the highest quality to our customers.
We have installed grading machines that can achieve grading in 5 micron for diameter . Our machines are highly precise and can handle rollers of various sizes and specifications. We are committed to meeting the highest standards of quality and precision, and our grading processes are no exception. We take great care to ensure that all our rollers are graded accurately and efficiently, so that they meet the specific requirements of our customers.
We ensure that the rollers undergo a meticulous process of washing, cleaning, and oiling, which aids in achieving the required level of cleanliness for Millipore check . After cleaning, the rollers are filled into stainless steel bins, and MTO cleaning, drying, and rust preventive oil are sprayed on them. We take great care during the packaging and dispatching of the products to ensure flawless delivery.
