With the emergence of energy crisis, electric vehicles came into being and get rapid development. The shift from fuel vehicles to electric vehicles marks the shortening of the value-added chain of the automotive industry and its parts suppliers, and more and more car companies are beginning to extend upstream. As the traditional engine has been replaced, the number of mechanical parts on electric vehicles has been greatly reduced, and the market demand for special machining tools for engine cylinder blocks, cylinder heads, crankshafts, camshafts and connecting rods has been decreasing year by year.

At the same time, the emergence of electric vehicles has spawned new metal cutting projects, such as the metal cutting of motor shafts, motor housings, battery brackets, and newly added various molds. Most of its components are meeting higher Under the production efficiency, the requirements for processing accuracy and quality are more stringent. In addition, light weight is also very important for electric vehicles. The lightweight of its body is mainly reflected in the application of new materials and its structural design, mold design and corresponding process manufacturing technology, which poses new challenges to tool and machine tool manufacturers.

With more than ten years of accumulated experience in the field of auto parts processing, Arrow Stone can not only provide innovative, efficient and reliable special tools and processing solutions for complex precision parts such as engines and gearboxes. At the same time, for the processing of key parts of electric vehicles, Arrow Stone has also been fully prepared. For the machining of these parts, Nanjing Arrow Piercing Stone can provide a series of advanced tool solutions to meet various working conditions and customer needs.

1.Arrow stone advanced tool solutions for new energy automotive motor housings

In new energy vehicles, the motor is a very important key component, and its performance directly affects the performance of the power system of new energy vehicles.

Some of the motors are integrated with the reducer and differential, some are integrated with the axle housing, and some are integrated on the wheels, resulting in different shapes and structures of the motor housing, but the machining characteristics of the housing It is similar. In order to adapt to the general trend of lightweight development of automobiles, the typical material of the motor housing is cast aluminum alloy, such as A6061-T6. The machining process of the motor shell mainly includes: milling, drilling, boring, reaming, thread and other processing.

2. Motor housing hole processing

1. Non-standard bridge type coarse boring cutter

High tool dynamic balance design to ensure machining stability.
Stepped boring cutter design, removing the allowance of multiple step sizes at one time
The tool body is made of aluminum alloy, which reduces the weight and overturning torque of the tool and is convenient for automatic tool change of the machine tool.

2, non-standard guide bar fine reamer

The design of the guide bar adjustable fine reamer can easily cope with the processing of 6-level holes.
The dimensional stability of production is better.
The design of multi-blade guide bars can offset the deformation in deep hole processing.

3. Carbide drill bit

For the drilling of aluminum alloy parts, Arrow Stone can provide overall hard alloy material and PCD material for customers to choose from. Combined with its optimized polishing chip holding groove and high-precision internal cooling hole design, it can obtain longer tool life while ensuring hole quality. And can provide customized complex multi-stage forming drill bits according to working conditions and customer needs.
