Jig and fixture design: Pneumatic or electric power?
Generally the fixture is powered by pneumatic or electric or both.
These 2 powers have their own advantages and disadvantages.
The pneumatic power has low efficiency, poor stability and large noise, which is suitable for some common products with low quality requirements. The electric motor running gently, high efficiency, good stability, the noise is small, suitable for precision, small products.
For above reasons, in many cases, the designer will choose a hybrid solution (which requires both electric and pneumatic drive), and will be more inclined to use electricity, The reasons are as following,
- The electric motor has wider adaptability and obvious advantages. For such fixture making, the cost of it may be higher than pneumatic one, but can be made up for in the production capacity and product quality;
- Because the pneumatic fixture has more cylinders and more control points, the program is not easy to develop; the motor, on the other hand, concentrates a lot of complex actions into a rotating period through the mechanism. Once every detail of the rotating period is electronically controlled, the efficiency and stability will be greatly improved. Also the subsequent process parameters can be easily adjusted or optimized.
At Accu, we provide CNC parts (metal parts, plastic parts), 3D printing (SLA, SLS) parts, sheet metal parts, vacuum casting parts. We are also able to design and manufacture jig and fixtures according to customers' requirements.
