Effective parent metal processing for valve seat and valve guide holes
The metal processing of valve seat and valve guide hole is the most demanding machining task in automobile industry. Due to the high requirement of the circular shape, the form is high, the pore type is a single slot, the adjustable reamer is a classic tool for machining tasks, which guarantees the requirement of tool life. However, this tool has its limitations because it has only one flute, so it satisfies the need to reduce the cycle.
For this purpose, the company has developed a multi-flute and dual adjustable double-tube double winch, ideally satisfying the need for effective metal processing for valve seat and valve guide valves:
In the diameter setting of the cutting edge of the two steps, a very long tool life is used to achieve the highest accuracy.
The highest cutting parameters are due to multi-slot and optimal cooling.
When the tool is clamped, it can be operated on the diameter of two steps.
Perfect results, thanks to the best tool design
A multi-channel two-step feed is used for the metal processing and valve guide hole of valve seat. Two identical design methods are used for inlet and exhaust valve processing.
Exhaust: the diameter of the valve seat is 28.5mm, the diameter of the valve guide hole is 11 mm, and each diameter is 6. The diameter of the two steps can be adjusted independently.
Inlet: valve seat diameter is 35.5 mm, valve guide rail diameter is 11 mm, each has 6 flute. The diameter of the two steps can be adjusted independently.
When the tool is clamped, simple, fast, high-precision diameter Settings allow the diameter to be recalibrated at any time. It will then increase the service life of the tool.
The reamer design provides a reliable and compliant process that requires roundness, shape precision and porosity, as well as extremely long tool life with extremely high cutting rates.
The transport of coolant makes the cutting edge optimal lubrication and supports the evacuation of the chip.
In particular, the complete machining of cylinder head, precision and economic benefit are the main requirements of tool suppliers. Due to multi-valve technology, a large part of the machining cost of the cylinder head is a large part of the total cost in pre-processing and processing of valve seat and valve guide rail.
In order to reduce costs, compared with the traditional single groove tool, using multiple slot playback device at the same time, the increase of cutting speed at the same time, keep the same precision and longer tool life, designed for the two steps of the diameter of the Settings.
The second step of the patent pending diameter setting
The body of the inner tool as the second step extension screw.
The internal work is screwed together with the external unit.
The expansion of the diameter of the step is accomplished through the specific integration taper of the internal work.
The simple rotation of the internal work has led to the second step diameter setting.
Therefore, the second step diameter setting can also be executed when the tool is clamped.
The ground flat on the inner knife body is suitable for adjusting the wrench.
The expanded screws are integrated into the tool head
The expanded screw is fully integrated into the tool head.
Compared with the traditional solution, the reamer is used to drill down to the bottom of the hole without a problem.
It can be processed through holes and blind holes.
A double-step double step two-step two step feed with double adjustable double step is used to successfully apply the machining of the initial hole of the following work piece:
