In order to cut costs, many of these firms purchase second-hand centre lathes.Ī used centre lathe is every bit as reliable as a brand-new machine, but it can be purchased at a significant discount. In modern facilities, the centre lathe is deemed too inefficient to be used for mass production processes, but many small companies still rely heavily on them. Replacement parts can be produced quickly and accurately by a centre lathe, which means machines being used for the main production process dont have to cease operations. However, a large number of businesses use them primarily for maintenance work. It is the simplest and most basic form of the universal lathe Headstock, tool slide, tailstock, workpiece mount, feed and a steady rest are its components Mainly used for maintenance work Quality Great offers Personalized What is a centre lathe used for A CNC centre lathe machine is commonly used in the manufacture of component parts for engines. These automated centre lathe operations are controlled by computers which are programmed in advance to carry out specific tasks. In recent years, however, CNC centre lathes have been introduced into large scale production facilities to speed up the process, cut production costs and remove the element of human error. The first centre lathes were manual machines that were operated directly by people. Perhaps the most common use for a lathe is the manufacture of component parts for the combustion engine. This versatile basic form of universal lathe can be extended with useful features (e.g.Ĭentre lathes differ on many technical parameters, such as turning diameter, turning length, centre height, distance between centres, spindle bore and jaw chuck.Īt Surplex you can quickly purchase by auction cost-effective used centre lathes -among other machine tools- including modern models from VDF and other manufacturers. The first 2-speed 6.54 hp motor was replaced by a 6.54.5 unit that allowed a choice of two speed ranges: the original 12.5 to 1000 rpm and a slower 10 to 800 rpm.Ī workpiece is fixed in the tailstock and clamped into place to ensure it cant move during the manufacturing process. The Celtic 20 also had changes made to the screwcutting arrangements with the new settings providing 53 inch pitches (63 previously), 45 metric threads (35 before) but the same number (54) and rates of longitudinal and traverse feeds. In line with these changes the optional threaded spindle was (thankfully) dropped and the options introduced of either a long-nose taper in a L0 size, a modern Cam-lock fitting or even a 2 Bayonet.

The lower-power 2-speed motor (2-1.6 hp) was dropped and the original high-power unit (3-2 hp) became the standard fitting with a 4-2-8 hp motor introduced for the high-speed version-although the spindle speeds remained, as before, at 24 to 1000 rpm and 38 to 1600 rpm.
