What Are The Differences Between Dovetail Slide Table And Cross Roller Slide Table?

The manual sliding table can be used in a variety of high-speed and high-precision places, such as tooling clamping, transfer, positioning, visual inspection, measuring equipment, etc., with a wide range of applications. Dovetail chute slide and cross roller slide are widely used in manual slide. Now let's talk about the difference between the two manual slides.Get more news about linear sliding table suppliers,you can vist our website!

1. The structure is different. The dovetail chute is a guiding mechanism that slides along the inner and outer dovetail chutes; The cross roller type sliding table is a guiding mechanism that arranges the rollers in a mutually orthogonal manner on two V-shaped groove guides, and the rollers roll along the V-shaped groove while the table moves.
2. The accuracy and stroke are different. The cross roller sliding table has high accuracy, and the straightness accuracy can reach 2 μ m. Small stroke; The straightness accuracy of dovetail chute is generally 20~30 μ m. Its sliding is flexible and can achieve greater stroke.

3. The operation adjustment speed is different, the dovetail groove sliding movement adjustment speed is fast, the gear rack type adjustment knob can move forward or backward 18mm for one turn, while the cross roller type sub micrometer knob can only move forward or backward 0.5mm for one turn. Fourth, the price is different. The dovetail groove type slide is simple in structure and cheap, while the cross roller type slide is relatively complex in structure, high in precision and high in price.
We should consider the following aspects when purchasing the manual sliding table:

1. Is the sliding table movement;

2. It refers to the moving accuracy of the sliding table, including straightness and parallelism accuracy;

3. It refers to the load resistance of the sliding table, and refers to the force that the sliding table can bear when the center of gravity of the workpiece is located in the center of the sliding table;

4. It refers to the allowable torque load of the sliding table, which refers to the force that the sliding table can bear when the center of gravity of the workpiece deviates from the central part of the sliding table.
