May 2, 2017 Facebook Twitter LinkedIn Google+ CNC Machine

Vertical milling machine and horizontal milling machine compared to the main difference is the vertical arrangement of the spindle, in addition to the spindle layout is different, the table can be up and down, vertical milling machine with a relatively flexible milling cutter, a wider range of applications. You can use end mills, machine cutter cutter, drill and so on. Can be milling keyway, milling plane, boring and so on.

Horizontal milling machine can also use the above tools, but not as convenient as the vertical milling, mainly can use the rack to enhance the tool (mainly three blade cutter, sheet cutter, etc.) strength. Can be milling, milling plane, cutting and so on. Horizontal milling machines are generally equipped with vertical milling head, although the vertical milling head function and rigidity than vertical milling machine is strong, but enough to deal with vertical milling. This makes the horizontal milling machine overall function than the vertical milling machine strong. Vertical milling machine does not have this feature, can not be processed for horizontal milling of the workpiece. Productivity is higher than horizontal milling machine.

2.2 Maintenance measures

Before operating the machine, you should carefully read the machine’s instruction manual, fully understand the machine’s technology and function, according to the provisions of the way.
Wearing a uniforms.
Always check the machine and the machine around the obstacles.
Do not use the wet hands to operate the machine.
Refer to the inspection parts of this specification for regular inspection, adjustment and maintenance.
Do not arbitrarily disassemble, change safety devices or signs and protective devices.

2.3 repair method

Vertical milling machine vertical milling head, the main wearing parts are spindle, spindle sleeve and sleeve body hole. These parts, in the absence of serious wear and tear in the case of failure can generally do some repair and continue to use. The repair of the wear parts are as follows:

1, the spindle repair: XA5032 vertical milling machine milling head spindle structure and XA6132 horizontal milling machine milling head spindle structure is basically the same, the repair method can refer to.

2, the sleeve hole repair: sleeve body hole wear will lead to roundness of the hole, cylindrical degree of error increases, the surface roughness deteriorated. Due to normal use, will not produce serious wear and tear, it is generally only need to repair by grinding, you can restore accuracy. But before the repair need to do a separate set of grinding rod for grinding use.

3, sleeve repair: When the sleeve wear is not large, the body hole repair volume is also small, the sleeve can be used after repair. The purpose of repair is to compensate for its outer diameter wear, so that the sleeve and the body with the gap to meet the requirements. The repair of the sleeve is generally done with a tinplate repair process or a new sleeve is replaced.

First, the spindle outer cone damage repair

The front end of the XA5032 vertical milling spindle front end is the mounting base of the bearing 3, and the left outer circle is the mounting plane of the adjustment ring 2. The wear between them affects the spindle accuracy and cutting performance. The repair using brush plating technology to repair. The main advantage of the brush plating is that the bonding strength between the brush coating and the spindle material (45 # steel) is greater than 70N / mm2, the workpiece heating temperature is less than 70 ℃, will not cause the spindle deformation and metallographic changes, to meet the spindle repair requirements.

1,Brush plating process

Spindle surface mechanical preparation → electricity net → tap water rinse → 1 # activating fluid activation → tap water rinse → 3 # activated fluid activation → tap water rinse → no electric wiping → brush plating special nickel playing base → brushing fast nickel for size layer to the specified thickness → post-plating treatment → mechanical processing of the coating.

2, Brush plating process content

(1) mechanical preparation before plating
The spindle mounted on the lathe, respectively, at both ends of the repair 60 ° center hole, surface roughness Ra0.8. And then on the universal cylindrical grinder to the center hole as a base grinding 1:12 outside the cone and the left side of the park, grinding less good. And then wash with acetone to be plated surface, and with polyester adhesive tape will not be plated adjacent parts of the paste to protect, to prevent misplaced.

(2) electricity net
In the above-mentioned clean-up on the basis of electricity with electricity liquid processing workpiece to be plated surface, to rust. To the oil standard is flushing water film can be evenly separated in the workpiece surface. Note that the net time should be short, to reduce the workpiece hydrogen leakage.

(3) activation
Select the appropriate activator to activate the surface of the workpiece to remove the oxide film on the surface of the workpiece so that the surface of the workpiece exposed metal matrix for the coating and the substrate to create a good combination of conditions. But should pay attention to avoid the current, the activation time is long, the workpiece temperature caused by the workpiece surface oxide layer. After the discovery of the oxide layer should be cleaned immediately.

(4) brush the transition layer
On the basis of activation, followed by brushing special nickel as a transition layer, the brush coating thickness of 2μm can be. Brush plating is mainly to improve the bonding strength and stability of the coating and the substrate.

(5) brush plating working layer
Brush the transition layer after brushing the working layer quickly nickel, without washing. First no electric wiping 3 ~ 5μm, the polarity, voltage, speed can be the same power and then brush plating. Soak the spindle with warm water, heat the bath to 50 ℃, start plating with low current, and then gradually increase the current, to avoid the spindle and the bath temperature is too low and the choice of high voltage, high current caused by excessive coating stress, coating cracking Peeled off.

(6) finishing after brush plating
Remove the shield to protect the anode, cleaning the remaining residue on the workpiece, and for rust treatment.

(7) spindle plating to restore the size of the mechanical processing
The spindle mounted on the universal cylindrical grinder, the choice of green silicon carbide wheel. Because the nickel coating in the grinding without spark, in order to facilitate the knife, coated with red powder on the coating. Because 1:12 outer cone is only a big end of wear, so just looking for positive 1:12 outer cone no damage to the large surface, the coating recovery at the level of grinding; also with the new bearing cone hole with research, Color coverage can reach more than 80%.

Second, the bearing E46117 preloaded work

In order to improve the stiffness of the spindle support and reduce the axial axial movement of the spindle, apply the preload to the bearing E46117 to make the pre-deformation between the rolling element and the inner and outer rings to eliminate the clearance, improve the shaft rotation precision and rigidity, reduce the vibration and noise, Bearing load uniformity and service life.
