To orient a workpiece accurately for live tooling (like a drill), a rotary Caxis can be employed, creating a 4axis machine. Tiny motors in the tooling mounted on the turret convert the lathe into a conventional milling machine. These servomotors hold position to allow for contouring motion in 4axis CNC lathes.
"TCR Machining Ltd. is a long time user of Nakamura turning machines (SC200LMYS and AS200LMYS). Over the 10+ years I have gotten to know these machines very well. The learning curve can be slightly steeper than other machines, but once you understand the logic, there are very few limitations.
Milling machines are extensively used for facing seating and mating flat surfaces. Milling is often the first operation on the workpiece. Figure shows simple face milling fixture. The workpiece is positioned by three adjustable spherical ended pads 'A'. These pads are adjusted to suit the variation in the size of workpiece and lock in the

Vertical Milling Machine is Most Common • Milling machines are very versatile. They are usually used to machine flat surfaces, but can also produce irregular surfaces. They can also be used to drill, bore, cut gears, and produce slots. • The type of milling machine most commonly found in student shops is a
(a) Surface grinding machine (b) Cylindrical grinding machine (c) Internal grinding machine (d) Tool and cutter grinding machine Surface grinding machine: This machine may be similar to a milling machine used mainly to grind flat surface. However, some types of surface grinders are also capable of producing contour
Home // Mechanical Engineering // Production Technology. 645. Side relief angle of a single point tool is the angle. which the face of the tool is inclined sideways. which the face of the tool is inclined towards back. the surface of the flank immediately below the point and a line drawn from the point perpendicular to the base.
Milling is done using a cylindrical milling tool mounted in a milling tool holder that is then mounted in the tool spindle on the machine. End Mills End mills are the most common milling cutters. End mills are available in a wide variety of lengths, diameters, and types. A square end mill is used for most general milling appliions.

Horizontal Milling Machine. 1. Column Base. Column including base is the main casting that supports all other parts of milling machine. The column contains an oil reservoir and a pump which lubries the spindle. The column rests on the base and base contains coolant reservoir and a pump which is used during machining operation that requires ...
5 Axis machining implies that a workpiece can be automatically manipulated from five sides at one time. In addition to automatic movements along the X, Y, and Z axes, 5 axis CNC machines can select two of the three rotational axes (A,B,C) to use. The A, B, and C axes perform a 180° rotation around the X, Y, and Z axes, correspondingly.
