In general, the wider the wheelbase, the higher the driving comfort, but some home-made cars do not have directional assistance. If the front wheels are too wide, their steering wheel will be "heavy," affecting driving comfort. In addition, the track distance also has an influence on the total width, total weight, lateral stability and safety of the car. The greater the track distance, the more favorable the smoothness of the operation, and also the favorable shape of the body and the spaciousness of the carriage, the better the lateral stability. However, since the track width is wide, the total width and total weight of the automobile are also generally increased, and the problem of sluging to the side of the vehicle body is apt to occur. If the track width is too wide, it will affect the safety of the car. Therefore, the track distance should be compatible with the width of the car body. In general, the larger the wheelbase, the higher the driving comfort and the more favorable the smoothness of the operation. At the same time, it is also advantageous for the shape of the car body and the spaciousness of the carriage. The lateral stability is better. CNC Milling Machine is an automatic processing equipment developed on the basis of general milling machine.The processing techniques of the two are basically the same, and the structure is somewhat similar.CNC milling machines are divided into two categories: without a tool magazine and with a tool magazine.The CNC milling machine with a tool magazine is also called a machining center.

The front track and rear track are not necessarily the same.
The equal distance between the front and rear wheels is the best. Off-road vehicle selection.
The front track is more manoeuvrable than the rear track. Household cars usually use this form to help with safety and also help with the layout of the engine compartment and steering.
The front track is smaller than the rear track and has a tendency of transitional steering. The general sports car is used.
Features
In addition to the characteristics of ordinary milling machines, CNC milling has the following features:
1.The parts are highly adaptable and flexible, and can process parts with particularly complicated contour shapes or difficult to control dimensions, such as mold parts and shell parts;
2.It can process parts that cannot be processed or difficult to machine with ordinary machine tools, such as complex curve parts and three-dimensional space surface parts described by mathematical models;
3.Parts that can be processed in multiple processes after being able to process a single clamping position;
4.The processing precision is high, the processing quality is stable and reliable, the pulse equivalent of the numerical control device is generally 0.001mm, and the high-precision numerical control system can reach 0.1μm. In addition, the numerical control processing also avoids the operator`s operation error;
5.High degree of production automation, can reduce the labor intensity of the operator. Conducive to the automation of production management;
6.High production efficiency. CNC milling machines generally do not need special process equipment such as special fixtures. When replacing workpieces, it is only necessary to call the machining program, clamping tool and tool data stored in the numerical control device, thus greatly shortening the production. cycle.
Secondly, the CNC milling machine has the functions of milling machine, boring machine and Drilling Machine, which makes the process highly concentrated and greatly improves the production efficiency.
In addition, the spindle speed and feed speed of the CNC milling machine are infinitely variable, so it is beneficial to choose the best cutting amount.
The automobile wheelbase is the distance between the centerlines of the trajectories left by the wheels on the ground. If the ends of the axle are double wheels, the wheelbase is the distance between the two center planes of the two wheels. The car's track is divided into the front track and the rear track. The front track is the distance between the center planes of the front wheels and the rear wheel track is the distance between the center planes of the rear wheels.
