Rajkot is one of Gujarat's great engineering towns. Its industrial areas, including Aji GIDC, Metoda GIDC and Shapar-Veraval, are home to thousands of units making diesel engines, pumps and motors, castings, forgings, auto components and machine tools. Most of them share the same lubrication problems: coolant that smells, CNC axes that chatter, parts that rust in the monsoon and belts that wear out early.
Most Rajkot machine shops can run on a short list: a soluble cutting oil kept at the right concentration, a neat cutting oil for automats and threading, a slideway oil for CNC guideways, an anti-wear hydraulic oil for chucks and power packs, an EP gear oil, a general EP2 grease, a rust preventive and the right V-belts. Control and consistency matter more than brand.
| Machine or process | Usual lubricant or belt | Watch point |
|---|---|---|
| CNC lathes and VMCs | Soluble cutting oil (about 4–6%), slideway oil VG 68 | Coolant concentration, tramp oil |
| Automatic and cam lathes, threading | Neat cutting oil | Staining on brass and copper parts |
| Grinding machines | Soluble oil at low concentration | Burn marks, rust |
| CNC chucks, turrets, hydraulic power packs | Anti-wear hydraulic oil, VG 32–68 as specified | Oil temperature in summer |
| Power presses | Gear oil and grease as specified | Clutch and bearing lubrication |
| Foundry sand plants, shake-outs | EP2 grease, EP gear oil | Abrasive sand everywhere |
| Induction furnace tilting and hydraulics near molten metal | Fire-resistant hydraulic fluid where specified | Fire risk from leaks |
| Lathes, drilling machines, compressors | Classical A and B V-belts | Tension, alignment |
Coolant problems cost Rajkot job shops in tools, rust claims and sick leave. The fixes are simple:
Automatic lathes, Swiss-type machines, thread rolling and gear cutting usually run better on neat cutting oil. For brass and copper parts, which are common in the region with the Jamnagar brass industry nearby, choose a non-staining neat oil. We compare the options in neat cutting oil vs soluble oil.
CNC guideways need a true slideway oil, not hydraulic oil, to avoid stick-slip and to separate from coolant. Using the right one improves surface finish and stops slideway oil from spoiling the coolant. Read our slideway oil guide.
Rajkot's monsoon humidity rusts machined parts quickly, especially castings waiting between operations. Keep coolant concentration up, dry parts before storage and use a rust preventive suited to the waiting time. Our rust preventive oil guide explains the choices.
Hydraulic leaks near induction furnaces, molten metal or hot forgings are a fire risk. Where the equipment maker specifies it, use a fire-resistant hydraulic fluid, and keep hoses and fittings in good condition.
Lathes, drilling machines, compressors, blowers and pumps mostly run on classical A and B section belts. The common causes of short belt life are loose tension, worn pulleys and mixing old and new belts. Use our V-belt size chart to identify sections and the tension guide at every change.
Many units keep 15 or more lubricants where 7 or 8 would do. A short list makes ordering, storage and training easier and cuts mistakes. Banesto is a Gujarat-based manufacturer of industrial lubricants and Beltone V-belts, and supplies across Gujarat. Send us your machine list and we will suggest a simple list for your unit.
Which cutting oil is best for CNC machines?For most CNC turning and milling of steel and cast iron, a soluble cutting oil at about 4–6%. For automats, threading and brass parts, a neat cutting oil often works better.
Which oil is used for CNC slideways?A slideway oil, usually ISO VG 68 for horizontal ways and VG 220 for vertical ways, as the machine maker specifies.
Why does coolant smell in machine shops?Bacteria growing in still coolant, fed by tramp oil and low concentration. Skim tramp oil, keep concentration right and circulate the coolant.
Which V-belts are used on lathes and drilling machines?Usually classical A or B section belts. Read the code on the old belt or measure its section and length.
