The importance of engine turning in car performance
What is cylinder turning and why is it necessary?
Signs of the need to turn the cylinder
- Blue smoke coming out of the exhaust: This is a sign of oil burning, which usually occurs due to the expansion of the cylinder and the inability of the rings to seal the oil.
- Decreased engine compression: If the cylinder is oval, the compressor escapes and the engine power drops drastically.
crankshaft; The art of precision and balance
The specialized steps of turning the crankshaft in Heydari turning
- Crack detection test: Before sharpening, the crankshaft is tested with Magnaflox methods to ensure the absence of hairline cracks.
- Precise measurement: The diameter of the journals (axes) is measured to determine the appropriate bearing size.
- Polishing: After turning, the surface of the crankshaft is polished to minimize friction.
Why Heydari lathe is the best choice.
In today's competitive market, it is difficult to find a skilled turner who has both sufficient knowledge and modern equipment. Tashkari Heydari by combining traditional experience and modern knowledge, offers services that are different from other competitors.
1. Advanced and calibrated equipment
One of the basic principles in Heidari carving is to keep the equipment up to date. The cylinder turning machines, honing machines and crank stone machines available in this collection are all world-renowned brands and are periodically calibrated. This causes human error to be minimized and the accuracy of the work increases to the micron level.
2. Using the plateau honing technique
Many lathes are only satisfied with boring (rough turning). But in Cylinder Turning by Haidari Turning, the final honing operation (cylinder polishing) is done with special precision so that diagonal lines (Cross Hatch) are created to keep the oil on the cylinder wall properly. This technique causes better sealing of the rims and increases the life of the engine.
3. Speed and promise
We know that leaving the car in the repair shop is expensive. The Heydari turning team, with accurate time management, delivers orders for cylinder turning and crankshaft turning in the shortest possible time without sacrificing quality.
The effect of cylinder turning on fuel consumption and emissions
It might be interesting for you to know that the quality of the cylinder head has a direct relationship with the fuel consumption of the car. When the cylinder is properly cut and polished in Heydari turning, the piston rings have the best contact with the wall. This issue has two basic benefits:
Firstly, the escape of fuel and air mixture is prevented, so all fuel energy is converted into driving force. Second, the oil does not penetrate into the combustion chamber. The end result is reduced fuel consumption, increased acceleration and reduced exhaust emissions. Our services at Tashkari Heydari not only help the health of the engine, but also save on your current fuel costs.
Technical points about bearings and crankshafts
One of the main challenges in crank turning is maintaining the hardness of the crankshaft surface. Crankshafts are usually surface hardened. If the grinding is done too much, the hard layer will be destroyed and the crankshaft will be weak. Our experts in Heydari Carving with high technical knowledge only carry out the permitted amount of loading. If the damage of the crankshaft is deep, we sincerely offer the customer a replacement to avoid additional costs.
Also, the exact matching of the bearing with the machined crankshaft is of great importance. At Heydari Machining, after machining the crankshaft, we control the oil clearance using plasticage to make sure the engine oil pressure remains within the standard range.
Auxiliary services of Heidari turning
In addition to cylinder turning and crankshaft turning, Heydari turning group also offers other complementary services for complete engine rebuilding:
- Cylinder head reaming: removing warping of the cylinder head bottom and valve sealing.
- Cylinder bushing: If the cylinder is too widened and it is not possible to ream, we will return the cylinder to the standard size using high-quality bushings. Connecting rod.
- Pressure test (water test): Checking the cylinder block and cylinder head to find hidden cracks.
The cost of cylinder turning and crankshaft turning
The cost of turning services varies depending on the type of car (4 cylinders, 6 cylinders, etc.), the amount of damage and the type of service required. But Tashkari Heydari is always committed to providing fair and transparent prices. We believe that high quality does not necessarily have to come with an astronomical price. By referring to Heydari Carpentry, you will benefit from competitive tariffs and you will receive world standard services for the price you pay.
Investing in quality lathes actually saves you money. Because an unprincipled cylinder grinding or crankshaft grinding can jam the engine and impose costs of several tens of millions.
The role of engine oil in the life of machined parts
After your car's engine has been rebuilt at Tashkari Heydari, its maintenance becomes especially important. Newly machined parts (such as cylinders and crankshafts) require proper sealing. Using engine oil with the right viscosity and replacing the oil filter on time is the key to the longevity of the repaired engine.
At Tashkari Heydari, after delivering the parts, we will provide you or the relevant mechanic with the necessary advice on how to seal the engine (break-in period). This technical support shows our commitment to the final satisfaction of our customers.
Quality control process in Heydari lathe
No piece leaves the door of Heydari Carving workshop unless it has passed through strict quality control filters. After finishing turning of the cylinder, the final dimensions are checked with micrometers inside the gauge. Surface roughness (Ra) is measured to ensure the quality of honing.
In the case of crank turning, all journals are checked for roundness and taper. This obsession with quality control has made Heydari Carpentry recognized as a reliable reference for professional mechanics and authorized car dealers.
Bushing or cylinder turning? Which is better?
This is one of the frequently asked questions of customers at Tashkari Heydari. When the cylinder has scratches but the thickness of its wall allows it, cutting the cylinder and using a larger size piston (for example 0.50) is a better and less expensive option. This will keep the block's integrated structure.
But if the cylinder has already been cut several times or the damage is very deep, our experts at Heidari turning suggest bushing operation. In this method, the inner wall of the cylinder is shaved and a cast iron or steel bush with a standard size is pressed into it. Both methods are done with the highest accuracy in our collection, but our priority is always to preserve the original structure of the engine and reduce the customer's cost.
Customers' experience of Heydari turning services
Customer satisfaction is our biggest asset. Many customers who have turned to Heydari Machining for cylinder turning and crankshaft turning have expressed their satisfaction with the smooth running of the engine, the reduction of engine noise, and the complete elimination of oil burning. Collaborating mechanics also carry out the process of assembling the engine with more ease and reliability due to the high accuracy of machining our parts. When the precision parts are machined, the assembly of the engine will be faster and easier.
World-class technology in the hands of Iranian craftsmen
The automotive industry is constantly progressing and the alloys used in engines are changing. The technical team of Heydari Turning is constantly updating its knowledge in the field of new aluminum and cast iron alloys. The way of turning aluminum blocks with dry bush has fundamental differences with old cast iron blocks. Failure to follow these technical details can be disastrous. But at Tashkari Heydari, we have combined modern knowledge with experience to rebuild any type of engine, from domestic cars to luxury imported cars, with the best quality.
