Set groove on the parts, one is to facilitate the later order processing, such as lathe turning thread relief groove, grinding the process tank, etc. ;
2 it is to ensure the parts during assembly, the axial positioning accuracy, such as the shoulder slot;
3 it is to move or t-shaped road and fastening the dovetail groove, etc. ;
Four is on the movement of teamwork, set different forms of lubrication groove, seal or dust, and the function of seal groove and dust-proof slot, etc.
Groove structure form of the rectangular groove, forming, oblique tao and transverse groove, etc.
According to the groove area, can be divided into the groove and the groove.
Rectangular groove cutting: when turning the rectangular slot car slot cutter geometry parameters and the installation method and the cutting knife broadly similar, they also have two symmetric point, Angle and the auxiliary Angle, after the main cutting edge and workpiece axis parallel.
The basic ways of cutting rectangular groove is: 1)
When cutting a narrow rectangular slot, the width of the main cutting edge and the width of the groove are equal, the length of the cutting tools is slightly greater than the groove depth, turning a straight into the car.
Turning wide rectangular groove, usable narrow slot cutting knife, points about several rough turning up the knife, after the trough bottom and two sides leave allowance, and finishing tool car the size.
Grooving cutting, grooving including circular trough and the trapezoidal channel, etc.
Narrow circular trough or trapezoidal groove, groove groove grinding blade into the car and forming the shape and size of the same, in the form of a transverse feeding of the car.
Wide deep grooving, especially the inner hole grooving, due to restricted by turning stiffness, often take the following two ways: (1) cutting in two steps.
Usually use cutting knife first car straight flute, and then use forming knife cutting forming.
(2) about knife feed or oblique feeding.
Lathe when wei shaped groove, wide, deep, but in the slide horizontally into the mackerel, shake small skateboards, made tool or trace moving left or right, form a single cutting feed up around the edge of the sword;
Or skateboarding in the transverse feed at the same time, shake small skateboards, makes the tool trace moving along a direction for the single inclined to feed.
After rough turning left in quantity, reoccupy finishing tool car to size.
Oblique groove cutting: groove is used for the process groove grinding cylinder and end at the same time, the formation of the direction of the cylinder and the end face two empty knife.
Oblique grooved points straight and circular arc form, general inclination to 45.
, lathe cutting knife has the characteristics of inner hole tool, ought to according to the size of the trench arc, in various parts of the cutting edge, should be ground into the corresponding arc Angle.
When cutting, transfer small skateboard to 450, with a small skateboards cutting forming at a time.
Transverse groove cutting: cutting end groove cutting knife, a cylindrical turning tool and the comprehensive properties of inner hole tool, both inside and outside two point, an equivalent cylindrical turning tool, lathe another is equal to the inner hole tool.
Grinding cutting knife.
Facing straight groove end face straight groove cutting blade geometry.
The lathe tool lateral tip.
Equivalent of turning inner hole, so it should be according to the end, the size of the circular arc behind the vice deputy after grinding out corresponding circular Angle R, to prevent the back into the outer groove face.
T car tank lorry t-slot, application three turning points in three steps: 1)
With face straight groove cutting knife, longitudinal feed, the car out of the end face straight flute.
Switch to bend right cutting knife, hole straight flute like car, car out of the lateral grooves.
With bend left cutting knife, car inside groove.
Car dovetail tank lorry steps and methods of the dovetail groove and the method of cutting t-slot basic same, also divided into three steps with three kinds of tool, namely first and facing straight flute, use left, right knife bevel forming respectively, make the dovetail groove shape.
When turning T slot and dovetail groove, turning the cutting edge of outside, also should according to the principle of inner hole tool grinding.
Lathe again due to the width of the end face straight flute co. , LTD. , left, right elbow slotting knife and left, right knife bevel forming tool holder is small, the strength of the cutting head is poorer, so should be properly reduced feeding, and observe the chip removal condition, keep clear of in time.
In the use of high speed steel lathe tool, should also reduce the cutting speed, cutting fluid and filling.
