2023 05 12 CNC CNC prototype machining is a manufacturing process used to create a sample or prototype of a product. It typically uses computer-aided design (CAD) software and computer numerical control (CNC) machines to precisely cut and shape materials to create a model that resembles the final product. These prototypes can be used to test product design and performance and make necessary modifications and improvements.

VMT 2023 01 12 Four standard threads of metric system, inch system, modulus and diameter control can be turned on the CNC lathe. No matter which kind of thread is turned, a strict motion relationship must be maintained between the lathe spindle and the tool: that is, each revolution of the spindle (that is, the workpiece One turn), the tool should move evenly by one lead (of the workpiece).

VMT 2023 01 10 CNC milling is a machining process that uses computer control and cutting tools to selectively remove material from a workpiece and produce custom-designed parts. A CNC milling machine has a table that automatically moves (or rotates) the workpiece in different planes so that the tool can work on it.

VMT 2023 01 07 Tolerance in CNC machining refers to the allowable variation of a parameter within a specific range. This parameter can be a variety of measurable physical properties such as temperature, humidity, noise level, stress, solar radiation rate and velocity, etc., or it can be a physical dimension, such as the size of the space.

VMT 2023 01 05 PEEK (polyetherimide) is a high-performance engineering plastic material with excellent heat resistance, chemical resistance, mechanical strength and wear resistance. PEEK material is usually used in applications under high temperature, high pressure, high load and harsh environment, such as aerospace, medical equipment, automotive industry, electronic equipment, oil and gas exploration and other fields. It is also widely used in manufacturing processes such as 3D printing, CNC machining, and injection molding.
