What are the common movements of the three roller gates?

The three-roller gate, also known as the three-bar gate, is a kind of channel gate. It was originally introduced from abroad. The English name is “Tripod Turnstile Series”, which is the intelligent control terminal device for the entrance and exit of the pedestrian flow channel. It is specially used for the opening and closing of personnel exits and entrances, such as canteens, hotels, office buildings, museums, stadiums, clubs, subways, stations, docks and other places.
The rare three-roll gate movements in the country mainly have the following four models:
1. The popular all-active three-roller movement: It adopts the combination of electromechanical combined special-shaped sheave mechanism. When it is unobstructed, it actively reverses a certain angle forward, and the front pusher is smooth.
2, machine anti-reduction reverse three-roll gate movement: on the basis of a simple simple electromagnet movement to improve the past, can achieve anti-reverse, buffering effect.
3, the machine is simple and simple electromagnet three-roll gate movement: simple and easy to use, the effect is simple.
4. Fully active silent three-roll gate movement: Based on the foreign tributary high-speed three-roll gate, the ARM control technique adopted adopts an industrial-grade control method to achieve a brand-new product, and all products are started during operation. It is extremely stable with the shutdown, and can quickly achieve the brake lock.

The Introduction of PCD 
The PCD (Polycrystalline diamond) is a composite material, consisting of sintered diamond particles with a metallic binder. Diamond is the hardest material in absolute terms and therefore also the most resistant to abrasion. Used as a cutting tool, it has a good wear resistance, and a yield superior to traditional sharp carbide. The machined surface roughness with the PCD can reach comparable to the adjustment.

Main applications
â–²Processing of non-ferrous
â–²Aluminum alloys with high or low silicon content (pistons, engine blocks engine, wheels, carburetors, connecting rods, gear boxes, cylinders for brakes, etc.).
â–²Bronze and copper alloys (copper manifolds, engine bearings, bushings, connecting rods eyes, locations pumps etc.).
â–²Tungsten carbide (trafilatori rollers and other components sintered etc).
â–²Pieces composed of aluminum and lead, aluminum engine blocks with cast iron pipes reported
â–²Processing of non-metallic materials
â–²Very abrasive materials, such as ceramics industrial uncooked.
â–²Some fired ceramic: zirconia aluminum oxide, such as spark plugs and insulators.
â–²Glass, plastics with glass fibers, carbon fibers.
The Introduction of PCBN
PCBN has the characteristics of high thermal stability, high hardness, high wear resistance and. It`s inert to iron family element, hence PCBN is mainly used for the machining of high hardness and hard processed ferrous materials, such as d facing alloys, harden steel, pearlitic gray cast iron, high temperature alloy, high-speed steel, hard facing alloys, Ni-Cr alloy, powder metallurgy metals.
