The slotting machine is actually a vertical planer, which belongs to the same class as the bullhead planer in terms of structural principle. The linear reciprocating motion of the insert knife with the ram in the vertical direction is the main motion, and the intermittent motion of the workpiece in the longitudinal direction and the circumferential direction is the feed motion.
The two main types of motion in machining are the primary motion and the feed motion. The primary motion is the main motion provided by a machine tool or manually to cause relative motion between the tool and workpiece so that the face …
According to the same or opposite direction of the main motion speed and the feed direction of the workpiece in milling, it can be divided into forward milling and reverse milling. The milling accuracy can generally reach IT8~IT7, and the surface roughness is 6.3~1.6 um.
Machining methods (Milling) Main motion is rotating motion done by tool. Feed motion is linear motion done by work piece. The cutting tool is multi-toothed tool and where the contact occurs intermittently, less heat generated. It is fast and fine machining used for all kinds of surfaces. Types of milling machines A. Column and base (knee) machines.
What are the cutting and feed motions of it? Cutting motion is the table (workpiece) Feed motions is the tool . Relative Motions in Shaping & Planning Machines Dr. Amr S. Fayed Page 18 Note the main differences between shaping and planning machines. Grinding Machine ... Surface grinding machines ( for flat or formed profiles) Cylindrical ...
The milling cutter rotates as the main motion, and the stainless steel forgings and the milling cutter do the cutting processing method for the feed motion. Milling is one of the main processing methods of plane. During milling, the rotation of the stainless steel forging with the milling cutter of the worktable is the main movement.
1) The speed change of main motion and feed motion of the machine are all adopted hydraulic pre-selection centralized control, which can save the auxiliary time and increase the working efficiency of the machine. The indicator lamps are lighted up to give the signal during the course of speed and feed changing.
Slotter is mainly used to machine the workpiece of trough type. The workpiece on the worktable is longitudinally, laterally or rotationally moved during machining, and the cutter is moved up and down to cut the workpiece.
