Lathe Machine Operation

10 Lean Manufacturing Ideas for Machine Shops

Climb milling can be used advantageously on many kinds of work to increase the number of pieces per sharpening and to produce a better finish? We do indexing to divide circular work piece into six equal parts and then all the six parts are milled to an identical flat surface. Additionally, it can support the end of the workpiece using a center and can be adjusted to adapt to different workpiece lengths. An ordinary caliper may be classified as the following: 1.

Machone just clipped your first slide. Centering lathe c. The work is supported by a rectangular strip at one end and by a stop pin at the other side. The cutter used for this operation is cylindrical type or end mill type.

This machine shop realized significant savings after consolidating non-value-added walking time into the work done by just the two water spiders. It is curved portion at the opeations of the tool. Steel rule 2. It is box shaped, heavily ribbed inside and houses all the driving mechanism for the spindle and table feed.

Used for turning tool bits although it is very common in milling cutters and saw blades. The slotter has a vertical ram and a hand xnd power operated rotary table. Wheel lathe b. Turning is used to produce rotational, various di.

In addition to the right mix of traditional strategies, a new lean manufacturing toolkit can make high-mix, low-volume machining faster, more predictable and less expensive. Courtesy of Strategos Lean Manufacturing. Figure 2 : An example of material flows for a part family after implementation of a machining cell. Before, the parts machined followed a spaghetti diagram that sent them to different stations throughout the facility. Lean manufacturing for the machine shop might mean segmenting the product mix into manufacturing cells responsible for different part families. Co-location of all the machines, personnel and support services relevant to a given part family can streamline and simplify material flows.
