If you`re looking for a Cnc Plasma Cutter that provides industry-leading performance at an affordable price, Xuanlin CNC Plasma series presents several outstanding options. These CNC plasma cutting machines produce fantastic edge finishes, yielding unparalleled accuracy and quality of cut. Within our selection, we offer plasma Cnc Routers fitting every size and budget. Our CNC plasma tables are built for quality cuts.For our Xuanlin CNC plasma series, we use one-piece, all-welded steel frames, which ensure accuracy, longevity and the ability to handle more power. These machines are capable of using power supplies up to 120 amps, allowing a wide range of possibilities for what you can cut. Each CNC plasma cutter uses a helical rack and pinion drive system for the X and Y axes, while a precision ground ball screw is used for the shorter Z axis stroke. With automatic height control, the machine also maintains the proper height gap for the torch no matter where you are on the panel.

Circular gear pump internal gear machining process description:
1. Roughing shape on the lathe 2. Finished gear shape on the lathe 3. After the car is finished, it is sent to the inspection department, which passes the inspection and is delivered to the hobbing workshop 4. After receiving the roughing tooth 5. Fine milling tooth 6 After the delivery inspection department passes the inspection, it is delivered to the hard sector and the fire is completed.
Circular arc gear pump, that is, double arc plus sinusoidal curve compounded into a tooth shape, can completely eliminate the involute gear pump. The arc gear pump has continuous contact between the two meshing tooth profiles. It does not produce oil trapping phenomenon. It completely solves the phenomena of pump vibration, noise, and bearing load increase caused by the oil trapping phenomenon of the involute gear pump. Therefore, the arc gear pump has the advantages of low efficiency, low noise, and good energy-saving effect. This series of gear pumps are mainly composed of gears, shafts, pump bodies, pump covers, bearing sleeves, and shaft end seals. Gears are manufactured with double arc sinusoidal teeth. Compared with the involute gear, the most prominent advantage is that there is no relative sliding of the tooth profile during the gear meshing process, so the tooth surface is free of wear, smooth operation, no liquid trapping phenomenon, low noise, long life, and high efficiency. The pump is free from the shackles of traditional design, making the gear pump enter a new field of design, production and use.
