6 Tons Electric Servo Pullup Vertical Broaching Machine for Key Processing

Product Description

Electric Servo Vertical Broaching Machine
 

This series of vertical internal broaching machines can be used for broaching various geometric shapes of internal hole surfaces (such as internal splines of gears, etc.). It has high production efficiency, high precision, easy operation, and no pollution, and is suitable for mass production.



The machine tool adopts a broaching method in which the broach is fixed and the workpiece moves upward, which can improve the broaching accuracy of the workpiece. This series of machine tools can be made into a fully enclosed automatic loading and unloading broaching processing center according to customer needs. It has a loading mechanism, a transmission mechanism, a broaching main machine and a unloading mechanism, and can be connected with other machine tools to form a fully automatic production line.

This series of machine tools does not require a pit to be dug. The machine tool is equipped with an automatic brushing mechanism. It can also be equipped with an automatic rotating brushing mechanism according to customer needs to extend the service life of the tool.



This series of broaching machines can be equipped with our company's patented mechanisms such as pneumatic oil and gas cooling technology, automatic spray cleaning mechanism technology, and power brush cleaning technology, which can effectively clean the iron chips in the tool cutting groove, and play a cooling and lubricating role on the tool, control the temperature rise and deformation of the workpiece during the broaching process, and improve the broaching accuracy of parts.

The machine tool adopts servo drive and can be equipped with CNC system. It works smoothly, has stepless speed regulation, and is equipped with automatic, semi-automatic and manual working cycles. The machine tool is safely protected by electrical and mechanical devices.






Advantages:
Processing accuracy: Driven by electricity, the speed of product processing is completed in an instant, there will be no pause, and there will be no cutting marks on the surface of the product. The accuracy can be stabilized at 0.01~0.015mm (φ80), and the surface roughness is Ra1.6.
Safety and environmental protection: No oil leakage problem, low noise, anti-fool and anti-collision mechanism, meet the high requirements of safety and environmental protection.
More energy-saving: Power is consumed when the workpiece is processed, and no power is consumed when not processed. Energy saving comparison is more than 50%.
Lower maintenance cost: Only the ball head screws and magnetic levitation guide rails need to be replaced after long-term use, and they do not need to be replaced for 10 years of normal use. The control device has many error management functions and is easy to restore during repair.
More intelligent: Give instructions to the inverter through PLC for control.
Site requirements: Small footprint, no need to dig pits or ladders, easy to change sites.
Easy to replace: It is convenient to replace products, the cost of single-piece processing is low, and only simple operation training is required.
Automatic connection: The three sides of the equipment can be opened for connection, and the communication interface is reserved, which is easy to realize automatic connection.
Low failure rate: The failure rate is low. It adopts advanced Japanese technology to minimize the damage to components. It adopts three-stage filtration to further reduce the iron chips in the broaching oil.

A broach is a high-precision, high-efficiency multi-tooth tool that can be used to process internal and external surfaces of various shapes. Among them, carbide indexable broaches have the characteristics of high cutting efficiency and long service life, and their application is becoming more and more extensive. Due to the wide application of broaching processing methods, there are many types of broaches. According to the different forces, they can be divided into broaches and pushers. According to the different surfaces of the workpiece, they can be divided into internal broaches and external broaches. Internal broaches are used to process the inner surface of the workpiece, and common ones include round hole broaches, keyway broaches and spline broaches. External broaches are used to process the outer surface of the workpiece, such as flat broaches, forming surface broaches and gear broaches. According to the different structures of broaches, they can be divided into two types: integral type and combined type. The integral type is mainly used for medium and small-sized high-speed steel broaches; the combined type is mainly used for large-sized broaches and carbide broaches, which not only saves precious tool materials, but also can be replaced when the broach teeth are worn or damaged, extending the service life of the entire broach.
