（1）The thread of the chuck flange and the spindle is loose or the chuck positioning surface is loose; (2) The workpiece hole wall is thin and the clamping deformation: (3) The spindle bearing clearance is large, and the clearance between the outer diameter of the spindle sleeve and the box hole is large, or The roundness of the main journal is out of tolerance.
There are mainly eight aspects: (1) Blank bending; (2) The front and back centers are unequal in height or center offset.;(3) Improper top tightening force; (4) The axis of the main shaft of the lathe and the guide surface of the bed are not parallel in the horizontal plane;(5) The distance between the tool tip and the support of the follower tool post is too large; (6) The clamping rigidity of the workpiece is not enough; (7) The tool is worn out or the tool shaft is too thin in one feed, causing the tool to be cut (hole alignment); (8) Deformation caused by turning stress and turning heat.
(1) The tip of the turning tool is not aligned with the axis of the workpiece. (2) There is an error in the corner of the tool post or the offset of the tailstock.
It is often due to the following three reasons: (1) Poor lubrication, poor filtration of cutting fluid or improper selection. (2) The metallographic structure of the workpiece is not good. (3) The tool is poorly sharpened or the tool tip is higher than the axis of the workpiece.
The reasons are: (1) The axial movement of the main shaft is large or the main shaft bearing is seriously worn. (2) The chuck flange and the E-axis are loosely matched, the bottom surface of the square tool post and the tool post slide plate are in poor contact, and the gap between the medium and small slide plates is too large.
Generally it is caused by three reasons: (1)) The meshing gap of the transmission gear of the feed system is abnormal or damaged. (2) The gap between the pressure plates on the longitudinal sides of the large slide plate and the bed rail is too large. (3) The light bar is bent, and the coaxiality of the hole supporting the light bar and the light bar is out of tolerance or the bar is not parallel to the bed guide rail.
Linear tolerance range: within ±0.02mm; Angle tolerance range: ±1°; Roundness: within 0.005mm.
We have 2D coordinate measuring machine, 3D coordinate measuring machine, altimeter, caliper, micrometer, roughness meter, salt spray tester, CCD automatic tester, contour projector.
CNC machining center: 90 sets; CNC lathe: 65 sets.
Different product structures have different production and processing capabilities. Now each part can produce 12,000 pieces
There are several ways to press the tool: P is to clamp with the central cylindrical pin of the blade, and the clamping methods include lever type, eccentric type, etc. Moreover, the products provided by various tool vendors do not necessarily include all clamping methods, so please refer to product samples when choosing. Each clamping method is suitable for different forms of blades. For example, non-porous blades are commonly used for upward pressure (C type), and ceramic, cubic boron nitride and other blades are commonly used for this clamping method. The D and M models have reliable clamping and are suitable for occasions with large cutting forces, such as harsh processing conditions, rough machining of steel, and processing of short chips such as cast iron. P-type rake face is open, which is conducive to chip removal. Generally, medium and light cutting can be used. The S-type structure is simple and compact, and has no resistance to chip removal. It is a clamping method for counterbore inserts. It can be used with front inserts and is suitable for light cutting and small hole processing.
No kind of compression method is the most reasonable. It depends on the processing material and the occasion, and it must be combined with your company's inventory to meet the drawing requirements and save the cost of the tool is the most important.
Pay attention to the following points:
(1) Workpiece material and shape;
(2) Machine tool;
(3) Cutting edge related to the central axis of the part;
(4) Type of blade and chip breaker;
(5) Carbide grade and coating Layer;
(6) Other cutting conditions that affect tool life.
The cutting blade is determined by the size of the blade required by the drawing; and the cutting blade seat is determined by the fastening of the blade and the machine tool.
The rake angle can sharpen the cutting edge, make cutting more brisk, and reduce cutting force and cutting heat. However, if the rake angle is too large, the strength of the cutting edge and the cutting edge will decrease, and the heat conduction volume of the tool will decrease, which will affect the service life of the tool. The size of the rake angle also has a certain influence on the surface roughness, chip evacuation and chip breaking. The strength and hardness of the workpiece material is low, and the rake angle should be larger, and vice versa. Therefore, the rake angle will directly affect the surface roughness.
