Lathe processing and slotter processing in Yokoyama, located in Takaida, Higashiosaka Yokoyama always sees a product like a photo. How is this shape? ? The procedure is roughly like this. First, determine the dimensions with a general-purpose lathe from the state of the bar, and then cut the outer shape with an NC lathe. At this stage, the tip is not yet square (in the picture above, the hexagonal tip is still a circle). In order to make it into a square shape, the outside is processed with a general-purpose milling machine such as square, hexagon, dodecagon ... and the shape like the photo is completed. Mr. Yokoyama, a master of general-purpose machines, sharpened the corners, grabbed them again and sharpened them repeatedly. The procedure is to change it four times for square machining and six times for hexagonal machining! After processing, measure the dimensions and finish while making fine adjustments. It looks like a beautiful craftsman, but it's an eye measure. Based on our many years of experience in manual processing, we are able to propose processing methods and cost cuts that are suitable for customers, and to be a consultant for processing. And the inside diameter processing is the slotter which was introduced last time. In the same way, cut grooves in squares, hexagons ... Convex ... Milling is used for processing such an outer shape. Concave ... On the contrary, processing of such an inside diameter is a slotter. Sizes Large to small with both hands. The round bar can be used in every form by Mr. Yokoyama who uses lathe, milling machine and slotter. It is used in processing in all fields such as processing of tools such as drivers and processing of automotive parts. Because of the abundant stock of materials and the flexibility of using general-purpose machines, it is possible to meet short-term delivery requests. Mr. Yokoyama is planning to add a new NC lathe in February to respond to more requests. Yokoyama who advances strongly with the attitude of "offensive" according to the trend of the times is truly! Next time, I will tell you if the level of Yokoyama Works will be improved by the introduction of NC machines. Thank you again, Yokoyama!
