With the development of modern machinery processing industry, the requirements for the quality and precision of cutting have been continuously improved, and the requirements for improving production efficiency, reducing production costs, and having high-efficiency automatic cutting functions are also increasing. As a part of the cutting machine industry, the products we provide will be the most modern and technological. Welcome everyone to discuss cooperation. Details:/
CNC Cutting Machine (English: CNC Cutting Machine) refers to the use of the computer's computer control part to give digital instructions in the form of digital parts, according to a given digital command to drive the movement of the machine tool, according to the specific drawing of the metal sheet according to the requirements of the Cutting programmed machine. The numerical control part of the CNC cutting machine can be divided into single-chip computer system and industrial computer system. Generally, the electronic image drawn by CAD is earned on a CNC cutting machine through a mobile storage device (such as a u disk), and the numerical control cutter then issues a digital command to cut the metal plate according to the drawn image.
CNC cutting machine stepper motor is an actuator that converts electrical pulses into angular displacements. Generally speaking, when a stepping driver receives a pulse signal, it drives the stepper motor to rotate in a set direction by a fixed angle (and stepping angle). You can control the angular displacement by controlling the number of pulses, so as to achieve the purpose of accurate positioning; at the same time, you can control the pulse frequency to control the speed and acceleration of the motor rotation, so as to achieve the purpose of speed control.
CNC cutting machine stepper motor is divided into three types: permanent magnet (PM), reactive (VR) and hybrid (HB);
Permanent magnet stepping is generally two-phase, torque and volume is small, the step angle is generally 7.5 degrees or 15 degrees;
Reactive stepping is generally three-phase, and large torque output can be achieved. The step angle is generally 1.5 degrees, but the noise and vibration are large. Developed countries such as Europe and the United States have been eliminated in the 1980s; hybrid stepping refers to the combination of permanent magnet and reactive advantages. It is divided into two phases and five phases: the two-phase step angle is generally 1.8 degrees and the five-phase step angle is generally 0.72 degrees. This stepper motor is the most widely used.

A bicycle fork is the part of a bicycle that holds the front wheel.
A fork typically consists of two blades which are joined at the top by a fork crown. Above the crown, a steerer tube attaches the fork to the bicycle and the handlebars (via a stem) allowing the user to steer the bicycle. The steerer tube of the fork interfaces with the frame via bearings called a Headset mounted in the head tube.
At the bottom of the fork, dropouts hold the wheel. Usually, either the axle is bolted to the fork, or a skewer passes through a hollow axle, clamping the axle to the fork.
The term fork is sometimes also used to describe the part of a bicycle that holds the rear wheel[citation needed], which on 19th Century ordinary or penny-farthing bicycles was also a bladed fork. On most modern bicycle designs the rear wheel is now attached to a rear triangle made up of multiple triangulated tubes, rather than an actual fork, but the rear fork usage persists
