In the manufacturing of automotive engines, cylinder blocks and cylinder heads are core components. Each part has extremely high requirements for precision, which is directly related to the performance of the engine. At the same time, in order to pursue high profits, parts processing enterprises require tools to be able to adapt to the production needs of high speed and long service life. LINKUT Tools has provided effective solutions to the difficult problems in the precision machining of cylinder blocks and cylinder heads.

Overcoming Difficulties in the Precision Machining of Cylinder Blocks

Top Surface of the Cylinder Block: The top surface of the cylinder block is connected to the bottom surface of the cylinder head, and the sealing requirement is extremely high. Meanwhile, the burrs in the water tank, high speed, and special materials pose great challenges to the tools. LINKUT uses ceramic blades for cutting, with CBN finishing blades as a match.

Front and Rear End Surfaces of the Cylinder Block: The front and rear end surfaces play a sealing role and have high requirements for roughness. LINKUT adopts ceramic blades and combines them with CBN finishing blades with adjustable height, optimizes the machining parameters.

Thrust Surface of the Cylinder Block: The thrust surface has strict requirements for precision, and the machining depth is large. LINKUT selects short and thick tool shanks and anti-vibration tool holders to improve the rigidity of the tools. It uses CBN blades and adjustable tools to ensure machining accuracy.

Cylinder Bores: The internal quality of the cylinder bores is related to the performance of the engine, and the machining length is long. LINKUT uses CBN blades and tool body support strips, which not only ensure the machining cycle but also guarantee the overall roundness of the cylinder bores.

Breaking Through the Challenges in the Precision Machining of Cylinder Heads

Top and Bottom Surfaces: The top and bottom surfaces of the cylinder head are combined with other components and have high requirements for roughness and production cycle. LINKUT uses PCD blades to meet the requirements of the production cycle with high speed, and the adjustable tool tip axis ensures the machining stability.

Valve Guide Bushings and Valve Seats: The valve guide bushings and valve seats are key parts and have strict requirements for precision. LINKUT uses PCD reamers with supports to machine the valve guide holes, and CBN blades with precise angle adjustment to machine the valve seat holes. With the help of adjustable flange tool holders, it ensures machining accuracy.

Each Section of the Camshaft Sub-holes: Each section of the camshaft sub-holes has high requirements for coaxiality, etc., and the hole length is long. LINKUT uses adjustable flange tool holders to ensure accuracy, provides a variety of PCD blade edge and groove options, and ensures the quality stability of the tool body through mature tool body processes.

Fuel Injector Holes: The fuel injector holes have high requirements for roughness and taper, and the cutting force is large. LINKUT selects appropriate edge angles and chip-breaking grooves according to the characteristics of the parts, and uses mature PCD edge processes to ensure the service life of the blades and machining stability.

With these solutions, LINKUT Tools has solved the difficult problems in the precision machining of engine cylinder blocks and cylinder heads, providing reliable support for automotive engine production enterprises.
