]]>Drilling as a machining process is often considered a challenging process due to multiple factors such as strain hardening, toughness, high plasticity, tendency to form built-up edges and difficulty in chip evacuation. The role of cutting fluid is indispensable to reduce both temperature as well as friction between chips and the drill flutes and additionally to clear off the hot chip debris. However, the conventional ‘flood lubrication’ process typically used for lubrication, cooling and chip evacuation, often trigger issues like frequent re-lubrication, abrupt tool wear, disposal of used coolant etc.
Among other lubricant application techniques, the process of spraying out limited quantity of cutting fluid as cold mist to the cutting zone has proved to be effective. With MQL, there is minimal or no need to clean the tool and workpiece regularly after every machining process. Additionally, the task of disposal of used medium gets eliminated completely.

]]>Exposure to regular bearing and part cleaners can cause uneasiness in the short term and adversely affect health in the long run.
Bearing cleaning and re-greasing is a part of the regular ‘Maintenance, Repair and Overhaul’ activity in all industries. Typically, the dismounted bearings contain used grease debris, scales and other foreign residues which need to be cleaned thoroughly for inspection prior to lubricating with fresh grease and re-use. Improper cleaning can impact performance and diminish bearing life. Based on the type of bearing, manufacturers have provided clear instructions on the process of dismounting and cleaning for small to large bearings.
While bearing manufacturers recommend an oil bath or rinse tank, It is common practice for maintenance teams in industries to set-up component cleaning machines that use water-based cleaners. This set-up is commonly observed in industries such as Railways where the quantum of bearings to be cleaned is huge and regular. Bearings cleaned through such parts washers with water-based emulsions are dried out thoroughly with hot air or through vacuum dry outs. BECHEM’s range of water-based cleaners (Beruclean 3843, Beruclean 113 EMF and Beruclean 111 EHF) for high pressure cleaning systems have provided excellent cleaning results in such set ups.
The alternate arrangement observed in heavy industries such as Steel and metal processing that operate with large, heavy duty bearings is to soak the used bearings in rinse tanks or by manually spraying and rinsing them with the cleaning agent. Subsequently the operator brushes off the residues from the bearing. Traditionally light oil, kerosene or degreaser based on Isopropyl alcohol are recommended as the cleaning agent. However, the industry practice has been to provide commonly available diesel, mineral turpentine oil (MTO) and kerosene as the cleaning agent to its Maintenance team.
While cleaning effect with diesel is good, the low flash point and continuous exposure of the personnel to the nauseating odour of diesel renders the working environment vulnerable. Apart from the known symptoms such as irritation to skin and eyes, continuous exposure to diesel without safety gear can affect central nervous system, immune and hormonal systems in adults.
Continuous exposure to kerosene is known to cause irritation to eyes and skin in humans. Studies have shown that chronic exposure to kerosene can result in drowsiness, irritability, restlessness and even convulsions. Flash point of kerosene varies between 23°C to 61°C.
Owing to their low flash points and associated safety concerns, authorities in many countries prohibit and dissuade industries from using diesel and kerosene as a cleaning.
Even more dangerous is the use of MTO as a cleaning agent, the health hazards and environmental impact associated with this traditional cleaning agent has been well established. Fortunately, with increased awareness, the use of MTO has waned within the industry. Disposal of used cleaning agent is also a factor that is controlled by Authorities and expensive to manage.

Beruclean Eco is a high-performance cleaner for de-greasing and cleaning of used industrial bearings and machinery components. Beruclean Eco is NSF H1 certified (food grade approved for incidental contact) and is biodegradable as well (OECD 301 F: 70% after 28 days). Compared to diesel which has a low flash point of 32°C, Beruclean Eco has a higher flash point of 70°C reducing the risk of accidental fire. The colourless cleaning liquid removes all types of oil and grease contaminations, waxes and typical residues within used bearing and parts. Beruclean Eco can be used for regular manual cleaning processes as well as in flood and immersion baths and ultrasonic cleaning machines.
As a bearing and parts cleaner with lower evaporation rate, Beruclean Eco is more stable than diesel thereby reducing the overall consumption rate. Irrespective of the size of bearing, Beruclean Eco has proven cleaning performance across industries including Steel, Automotive Components and Food & Pharma as well.

]]>Personnel deputed at the component cleaning section of a reputed cutting tool manufacturer were not too happy with the pungent smell of ‘mineral turpentine oil (MTO)’ that polluted the work environment.
While MTO provided just adequate cleaning, the Production team was on the lookout for a product that would provide better cleaning effect. Additionally, with bulk consumption and used oil output, the management was keen for a bio degradable alternative.
An effective cleaner that was physiologically harmless and eco friendly at the same time was need of the hour.
The Customer, a well established Indian brand in manufacturing HSS cutting tools is the largest exporter in its category and also caters to the biggest names in Indian machining and automotive industry. With a comprehensive product range of over 50,000 tools, the company offers multiple options for various machining applications.
With production of close to 50 to 60k cutting tool units manufactured every day, the customer consumed tons of MTO as a part of the cleaning process during both the raw material preparation stage as well as in the final finishing stage.
During the raw material preparation stage, the cleaner was used to remove dirt, grease and other impurities from the metal bar prior to machining operations. Similarly, the finished component was cleaned off any oil residues or grinding dust after the final operations.
The customer had set up inline cleaning systems through dipping for initial raw material preparation and intermittent cleaning requirements. Ultrasonic machines were installed for the final finishing process.
The company had continued to use MTO as the inexpensive cleaning agent in all the cleaning processes. Personnel continuously exposed to the pungent odor of MTO experienced mild headaches and nausea at end of their shifts. The Management was keen to replace MTO that impacted work environment and employee morale.
While MTO has fairly low ‘acute toxicity’ that could impact through vapor inhalation or through continuous skin contact, continuous exposure could lead to drowsiness, nausea as well as severe irritant dermatitis or even chemical burns. Long term studies have shown continuous exposure could lead to chronic central nervous system effects impacting memory, concentration and irritability.
The Quality and Production team on the other hand were not too impressed with the finish of the cleaning with MTO. Traces of impurities and oil could still be seen on the components.
At this juncture, BECHEM’s Product team pitched in with an advanced cleaning formulation that had proven better cleaning finish, was odorless as well as bio degradable. The Customer’s Production team promptly opened up for a trial of Beruclean S 4050 and measured the performance on following parameters,
To compare the performance of both the products, two 300 ml beakers were filled in with MTO and Beruclean S 4050 and left in ambient conditions (30 °C) for a period of 3 days. While there was marked loss of about 100 ml in the MTO beaker, the beaker with Beruclean S 4050 showed minimal loss of about 25 ml. During trials on one of the cleaning lines with Beruclean S 4050, it was recorded that there was a reduction of consumption by 67% compared to MTO.
At the same time, the Operators informed that Beruclean S 4050 dried off from the cutting tools within 3 minutes approximately. This evidence was recorded with temperatures hovering about 30 to 32°C at the shop floor.
There was remarkable improvement in the cleaning effect with Beruclean S 4050. Hardened grease residues, high viscous oils and stubborn dirt that used to be stuck on carbide and HSS rods with MTO had been cleaned with Beruclean S 4050.
The company personnel were pleased to work with the odorless cleaning agent that did not give them a nauseating experience unlike MTO. The operators voted completely in favor of Beruclean S 4050.

]]>The production team at an auto component manufacturing company had trouble cleaning its component bins, impacting both component and shop floor cleanliness. Having embraced ‘total quality management’, the ISO/IATF certified company was keen to arrive at an effective solution to this niggling issue.
The Auto component manufacturer supplies to top Auto brands with exposure to both segments of passenger and commercial vehicles. Credited as one of the largest manufacturer of steering yokes in India, the company’s product portfolio also includes, connecting rods, automobile housing, gears as well as other precision turned components.
With close to 30 years of experience, and having imbibed the principles of ‘total quality management system’ the company had mastered complexities in manufacturing critical automotive parts. Supported by a highly aware and ‘quality conscious’ work force, the company had adopted stringent quality checks and was known for its commitment to fulfil clients’ requirements with precision.
During one of its regular exercises to identify areas for improvement, the Production team at the works noticed unclean bins in use for moving auto parts from one department to another. These bins would often contain grease and oil residues that in turn would attract dust contaminants resulting in dry sludge over time. Dirty bins meant contamination threat for finished components and possible rejection scenario from the Customer.The team realized that the existing cleaning system for bins in place was not effective despite the best efforts. As contaminants remained visible, the team had to establish a secondary manual cleaning process that was unproductive and affected the workflow.
However, unclean bins did not reflect the quality standards employed and posed a potential embarrassing situation for the Production team during Customer visits. Also, unclean bins are a major reason for corrosion of finished components
Finished auto parts are subjected to tests to ensure cleanliness at supplier’s end and also at customer’s end. Millipore test is one of the popular tests to check for impurities. Failure in this test at supplier’s end results in additional cleaning of parts. In case of failure at the customer’s end would result in rejection of the entire batch.
The existing cleaning agent wasn’t sufficient enough to obtain cleaner bins. During a regular prospecting visit, the BECHEM team learnt about the concern of unclean bins from the Production personnel. The BECHEM team understood the criticality of the issue and suggested an inspection of the existing bin cleaning process.
Cleaning machine installed at the works used jet spray to rinse off impurities from plastic bins. The cleaning process utilized DM (de-mineralized) water along with regular washing powder with cycle time of 5 minutes. The setup with tank capacity of 400-liter had in built heater that could maintain the sump temperature up to 60 °C. However, the team observed the lack of filtration system in the existing set up resulting in accumulation of excess sludge at the bottom.
Upon examining the process followed, BECHEM suggested few modifications to the existing setup including installation of pre-filtration system, repositioning of heat sensors and increasing the size of exit valves for better drainage of sludge.
Product recommendation was very critical as the bin cleaning system utilized jet spray and hot water for cleaning. A typical solvent based cleaner with low flash point could cause a potential fire incident during the process. A water based cleaner with good wetting and soaking properties was vital.
BECHEM recommended Beruclean 113 EMF, a universal water-soluble alkaline cleaning agent with low foaming properties. Equipped with special wetting additives, the high performance industrial cleaner is suitable for Aluminium, Cast Iron, Steel and non-ferrous metals as well. Although alkaline in nature, Beruclean 113 EMF is compatible with the piping or flanges from copper alloys used in cleaning systems. Also, Beruclean 113 EMF is highly recommended for spray jet cleaning.
Beruclean 113 EMF provided a much better result with bin cleanliness compared to the washing powder. Additionally, with Beruclean 113 EMF, the cycle time reduced from 5 minutes to 3 minutes as well as reduction in dilution ratio from 4% to 1.5%.

Beruclean 113 EMF |
|---|---|---|
| Washing Cycle | 5 mins | 3 mins |
| Concentration (in percent) | 4% | 1.5% |
| Cleaning Effects | Required additional rubbing | No additional cleaning |
The Production Dept. was delighted with the results as Beruclean 113 EMF enhanced output, reduced opex and helped them in achieving their 5S objective. Additionally, with lesser contamination on finished parts, the company had attained higher success ratio in Millipore test.

achining of Cast Iron, is a tricky and demanding process. Inherent composition and properties of the metal pose stiff challenge to even the experienced machinist. The fine graphite residues generated during the machining process tend to stick on to the machine parts rendering it with an unenviable look.
If unattended, these impurities tend to form a thin oxidized film on surface of the machine parts. Chances of rust formation also cannot be ruled out. These can not only lead to choking of pipelines and nozzles but also significant reduction of machine lifetime.
Dirty machines not only put a question mark on your maintenance effectiveness but can also impede efficiencies. While chances of tool breakage and poor finish increase, the biggest impact is on the morale of the operator!
Don’t be surprised if the operator starts complaining about skin irritation and foul smell. With tempers running high and production targets to be met, this certainly is an undesirable situation.
What you need is a dependable metal cutting fluid. Like Avantin from BECHEM. An advanced range of synthetic and semi synthetic based cutting fluids for regular to even the severest of the machining processes.
BECHEM’s Avantin range of metal cutting fluids are developed with special formulations with superior flushing and detergent properties that ensure less stickiness thereby a stain free and sparkling machine. Apart from low consumption and increased sump life, the Avantin range also provides excellent corrosion protection to machines and components.
