Cnc Precision Parts Custom CNC Machining High Precision Cnc For Motor Spare Parts What is CNC machining? CNC (Computer Numerical Control) machining is a subtractive manufacturing technology: parts are created by removing material from a solid block (called the blank or the workpiece) using a variety of cutting tools. This is a fundamentally different way of manufacturing compared to additive (3D printing) or formative (Injection Molding) technologies. The material removal mechanisms have significant implications on the benefits, limitations and design restrictions of CNC. More on this below. CNC machining is a digital manufacturing technology: it produces high-accuracy parts with excellent physical properties directly from a CAD file. Due to the high level of automation, CNC is price-competitive for both one-off custom parts and medium-volume productions. Almost every material can be CNC machined. The most common examples include metals (aluminum and steel alloys, brass etc) and plastics (ABS, Delrin, Nylon etc). Foam, composites and wood can also be machined. The basic CNC process can be broken down into 3 steps. The engineer first designs the CAD model of the part. The machinist then turns the CAD file into a CNC program (G-code) and sets up the machine. Finally, the CNC system executes all machining operations with little supervision, removing material and creating the part.

The WBC series plastic barrel & case crusher is specially designed for recycling various vacuum plastic containers. Optimized design based on the traditional heavy-duty plastic crusher, increases the size of the crushing chamber, it does not need a shredder for primary shredding, and crush the material to the required size once. Thereby reducing the recycling process, reducing the cost, and improving the efficiency of recycling.

Zhejiang Laifual Drive Co., Ltd. is one of professional gear suppliers . We provide LSD Shorten Thin Harmonic Gearbox, LFS Ultra Flat Harmonic Gearbox, planetary reduction drive and so on. Want to know more? Please contact us. Planetary gearbox for sale can be powered by either electric motors, hydraulic motors, planetary drives for sale, or petrol or diesel combustion engines. The load from the sun gear in transmission is distributed to several sun planet gears which can either be used to drive an outer ring or a shaft or spindle. The central sun gear takes a high-speed, low-torque input. It drives several rotating external gears which increases the torque. The simple design is a highly efficient and effective way of transferring power from a motor to an output. Approximately 97% of the energy input is delivered as an output.

Wave Generator Harmonic Gear Reducer is made up of a ball bearing and an elliptical cam. The wave generator is usually attached to the input end, the inner ring of the bearing is fixed around the cam causing the outer ring of the bearing deforms to an elliptical shape. Flex Spline It is an elastic thin-walled component with gear teeth on the outer surface. Harmonic Gear Reducer is usually fitted to the output end. Circular Spline It is a rigid steel ring with internal teeth. Harmonic Gear Reducer usually has two more teeth than the flex spline, and generally mounted onto a housing. Harmonic drive working principle As a reducer, the harmonic gear reducer is often in status as the wave generator drives, the circular spline is fixed, and the flex spline is output end. When the wave generator is put inside of the flex spline, the flex spline is forced into an elliptical shape causing the flex spline teeth to engage with the tooth profile of the circular spline along the major axis of the ellipse, with the teeth completely disengaged across the minor axis of the ellipse. The rotation of the wave generator makes the flex spline deform continuously, the teeth change operating state in the process of engagement and disengagement, thus the motion transmission between wave generator and flex spline is realized. Characteristics of Harmonic Gear Reducer High accuracy A good percentage of harmonic gear reducer's teeth are meshed at all times and are engaged at two zones 180 degrees apart. This means influences of tooth pitch errors and accumulated pitch errors on rotational accuracy are neutralized, which assures high positional and rotational accuracy. High speed reduction ratio A harmonic gear reducer has high single-stage reduction ratios of 1/30-1/500. Three basic components along same axle without complex structures can provide high reduction ratios. High torque capacity Each tooth subjected to a negligible amount of force yet provides a high torque capacity because of the way the teeth come into contact with each other and because a good percentage of the teeth in the flex spline is engaged at all times. Small-sized and light weight While being less the size of conventional gearing mechanisms and less the weight, the harmonic gear reducer provides the same levels of torque and speed reduction ratios as its conventional counterparts enabling machinery and equipment to be made smaller and lighter. Superior efficiency and long life time As a professional harmonic drive company in China, Laifual produces harmonic drive reducers with superior efficiency and long service time. Quiet and minimal vibration operation Laifual's harmonic drive reducers also operate with quiet and minimal vibration.

ball valve is a shut off valve that controls the flow of a liquid or gas by means of a rotary ball having a bore. By rotating the ball a quarter turn (90 degrees) around its axis, the medium can flow through or is blocked. They are characterized by a long service life and provide a reliable sealing over the life span, even when the valve is not in use for a long time. Flanged ball valves are characterized by their connection type. The ports are connected to a piping system via flanges that are usually designed in accordance with a certain standard. These valves provide a high flow rate since they typically have a full-bore design. When choosing a flanged ball valve, besides the pressure rating, you also have to check the flange compression class which indicates the highest pressure this connection type can withstand.

KXC bellow seal valve has a compact structure and is one kind of control valve to balance the pressure. Bellows are used as the valve stem sealing components of the bellow seal valves. To avoid the leakage of the valve stem, the valve adopts the structure with bellows instead of stuffing boxes generally used for the ordinary valve or the structure with both bellows and stuffing boxes. The bellow seal valve is particularly suitable for pipelines of steam and flammable, explosive and hazardous media. Moreover, because of bellow's properties of deformation and aging resistance, the bellow seal valve overcomes the common latent defects, including temperature sensitivity and the aging of the stuffing box, and these defects are owned by the valve sealed by packing.
