First, the role of the knife The cutter cylinder is mainly used for the spindle cutter in the machining center machine tool, the CNC milling machine tool automatic or semi-automatic exchange mechanism, and can also be used as the clamping device of the clamp and other mechanisms. The 30# spindle ...Read more -
CNC machining center needs to do these things well for metal cutting
First, the turning movement and the formed surface Turning movement: In the cutting process, in order to remove excess metal, the workpiece and the tool must be cut relative to each other. The movement of the excess metal on the workpiece by the turning tool on the lathe is called turning motion,...Read more -
There are five ways to process aluminum alloy
1. Sand blasting is also called shot blasting The process of cleaning and roughening metal surfaces by the impact of high-speed sand flow. This method of surface treatment of aluminum parts can make the surface of the workpiece get a certain degree of cleanliness and different roughness,...Read more -
How to calculate the cutting speed and feed speed of CNC machining center?
Cutting speed and feed speed of CNC machining center: 1: spindle speed = 1000vc / π D 2. Maximum cutting speed of general tools (VC): high speed steel 50 m / min; super hard tool 150 m / min; coated tool 250 m / min; ceramic diamond tool 1000 m / min 3 processing alloy steel Brinel...Read more -
Machining accuracy of CNC lathe
1. Accuracy of machine tool: if the minimum accuracy of machine tool is 0.01mm, you can’t process products with an accuracy of 0.001mm on the machine tool in any case. 2. Clamping: select appropriate clamping process according to workpiece material, with moderate clamping force. For example...Read more -
7 steps to operate CNC machining center
1. Startup preparation After each start-up or emergency stop reset of the machine tool, first return to the reference zero position of the machine tool (i.e. return to zero), so that the machine tool has a reference position for its subsequent operation. 2. Clamping workpiece Before th...Read more -
