CNC Milling Machine Spindle
The cnc spindle is the heart of any mill. It consists of a rotating assembly with a taper where tool holders may be installed. A cnc spindle motor with optional transmission…
Recirculating Ball Screw in CNC Machines
Due to high friction between screws and thread sliding friction replaced by rolling friction to increase accuracy and transmission efficiency of CNC machine. The Recirculating ball lead screw and nut…
How to Make a Lead Screw Nut for a CNC Machine
This tutorial will show you how I made the 5 start 2 TPI lead screw nuts for my CNC. Other types of lead screw nuts with a different number of…
Convert rotary motion into linear motion
Lead screws are a common technology used to convert rotary motion into linear motion, and are often used to provide actuation to a set of linear bearings. Plastic lead screw…
Anti-friction Linear motion guide ways
Metal to metal contact has a relatively high coefficient of friction and results in higher wear and heat generation. To minimize this, anti-friction linear motion guide ways are used on…
Anti-friction
Different Types of Anti-Friction Guide-ways are 1. Hydro-Static Guideways 2. Aerostatic Guideways 1) Hydro-static Guide ways:- In hydro-static guide ways, air or oil is pumped into the small pockets or cavities machined into…
Friction guideways
CNC machine tools has made necessary the rapid response of slides to a command signal and constant frictional resistance to slide movement is desirable. The phenomenon gives rise of the…
CNC GuideWays
CNC Machine Guideways Precise positioning and repeatability of CNC machine tool slides are the major functional requirements of CNC machines. The inaccuracies that are caused is mainly due to the…
Building a CNC Machine
This is the first post in a series of four where we’ll be talking about CNC related stuff, mainly because CNC milling is awesome! For a long time we at…
CNC grinding machines – modern machine tools
CNC grinding machines are machine tools which use a rotating grinding wheel to achieve material removal on a metallic workpiece by means of cutting. Grinding machines are mostly used for the hard-fine…
