II. Precautions for using the DGMF-Mold-Clamps-SMT30 cylinder head honing mandrel tool
1. Before honing, the reciprocating stroke of the honing head should be adjusted well. It is the part of the abrasive strip sticking out from the upper or lower end of the workpiece in the honing hole, which is about one-quarter of the length of the abrasive strip and chooses the suitable feeding amount.
2. Before using the new sanding strip, the strip should be rounded, i.e., the sanding strip should be ground with the workpiece hole. Only when the sanding bar is rounded can the roundness and cylindricity of the honed hole be guaranteed. The roundness and cylindricity of the honed hole can only be guaranteed if the sanding bar is rounded.

What is honing?
Honing, also known as boring, is finishing a finishing surface with an oil stone (also known as a honing bar/cylinder hone stone) set into the honing head.
Honing is used in conjunction with the honing oil stone. It can greatly improve the machining accuracy and productivity of the parts with high precision and measurability. It can complete the general honing process and platform honing technology, etc.
The product specifications range from φ15 to φ1000, and various non-standard specifications can also be made according to user requirements.
The deep-hole honing head is adapted to vertical or deep-hole cylinder heads. We can use the honing cylinder head to do all kinds of deep-hole workpieces. The same is a small field when the tool uses the boring process.
What is the honing processing?
The workpiece is mounted on the honing table or in a clamp when honing. The honing head with several cylinder hone stones is inserted into the machined hole, driven by the machine tool spindle to rotate and make axial reciprocating movements.
The oil stone/cylinder hone stone strips are brought into contact with the hole wall with a certain pressure to cut away a very thin layer of metal. The Engine Cylinder Honing Mandrel Tool honing head is generally connected to the spindle in a floating connection.
There are several types of Engine Cylinder Honing Mandrel Tool honing heads: mechanical pressurized, pneumatic, or hydraulic with automatic pressure regulation.
The hydraulic pressure regulating type Engine Cylinder Honing Mandrel Tool is mostly used in production.
What are the characteristics of the honing process?
① Honing is an efficient processing method to make the workpiece processing surface achieve high precision, high surface quality, and high life, which can effectively improve the dimensional accuracy, shape accuracy, and reduce Ra value, but cannot improve the position accuracy of the hole and other surfaces.
② It can process cast iron parts, hardened and unhardened steel parts, and bronze parts, but it is not suitable for processing tough non-ferrous metal parts.
③ Honing is mainly used for hole processing. The original processing hole center is used for guidance in the hole-honing process. The processing hole diameter range is φ5 ~ φ500, and the depth-to-diameter ratio can reach 10.
④ Honing is widely used in mass production for machining cylinder holes, cylinder barrels, valve holes, and various gun barrels. It can also be used in single-piece small batch production.
⑤ Coaxiality cannot be determined when honing.
⑥ Compared with grinding, honing reduces workers’ physical labor, high productivity, and easy automation.
What is the application of honing?
Honing is mainly used for processing various cylindrical holes with an aperture of 5 to 500 mm or larger, such as cylinder barrels, valve holes, connecting rod holes and box holes, etc. The ratio of hole depth to aperture can be up to 10 or even larger.
Under certain conditions, honing can also process external circles, flat surfaces, spherical surfaces, tooth surfaces, etc. Cylindrical honing surface roughness generally up to Ra0.32 ~ 0.08 micron, fine honing up to Ra0.04 micron or less, and can improve the geometric accuracy of a small amount, processing accuracy up to IT7- 4.
The surface quality of flat honing is slightly worse.
How does a honing machine work?
Honing is generally done with a honing machine. The machine tool spindle and engine cylinder honing head are generally floating coupled; however, to improve the ability to correct the geometry of the workpiece, a rigid coupling can also be used.
When honing a hole, the engine cylinder honing mandrel head is generally set with 2 to 10 oil stones/cylinder hone stones around the outer circumference, driven by the machine tool spindle to rotate in the hole and make a linear reciprocating motion at the same time, which is the main motion.
At the same time, through the Engine Cylinder Honing Mandrel Tool in the spring or hydraulic pressure control, oil stone is evenly outside up to be processed hole wall for radial feed.
