Main equipment configuration and function

 

1,The main shaft is driven by a gear box and a servo motor.

The headstock sliding device can easily remove the headstock and honing tools from the machined hole after a honing cycle, remove the spindle bracket, and easily inspect and measure the diameter, and facilitate the replacement of stones and workpieces. The tool holder supports the weight of the honing head, so that the honing head is in a safe state and avoids scratching the workpiece.


2,Control system
Schneider PC control control system. 15-inch LCD touch screen operation, friendly man-machine interface, large information capacity, simple and convenient operation.


Collect data in real time, feedback and adjust parameters in real time. After connecting to the Internet, remote fault diagnosis can be realized, and equipment maintenance becomes simple.


Our super dynamic database of processing parameters, the operator only needs to input ID of the workpiece, and the machine will automatically generate the corresponding parameters such as spindle speed, spindle box gear, maximum load rate, maximum protection torque, etc. Minimize the operator's workload and effectively prevent wrong operations.


When honing blind holes, after setting the relevant parameters, it can perform short stroke or small pause function on the blind end of the blind holes and the two ends of the through holes only when the operator starts the machine. The commutation accuracy reaches 0.1 mm,the independent machining load online measurement and automatic correction program can realize automatic control of local honing.


3,Honing stone feed system
The high and low points in the hole and the taper of the inner surface can be detected in real time during the whole processing, and reflected in the display screen in real time in the form of graphics. No manual operation is required for the found high and low points, the machine will repair the high point by itself with a short stroke; when the processing curve is close to a straight line, means the cylindricity is highly consistent. At the same time, it also supports manual setting short stroke repair, and the number and amplitude of short strokes can be adjusted.


4,Tool slide
After honing, the spindle bracket can be removed from the slideway, which is convenient for inspection and measurement of diameter, and convenient for replacement of workpieces and stones as well. The tool holder supports the weight of the honing head. It keeps the honing head in a safe state without scratching the workpiece.


5,Cooling and Filtration System
The equipment filter system is equipped with a webbing filter, a magnetic separator and a filter screen three-stage filter device. The magnetic separator can automatically remove the honing mud and reduce the labor intensity of the operator. The filtering precision is less than20μm.


6,Programmable touch screen
The programmable touch screen makes it easy to enter the size of the workpiece, the machine will recommend the correct tool selection, and calculate the appropriate spindle speed. The touch screen can also display the real-time working status: the load of the spindle, the high and low points in the workpiece, the position of the honing head, the honing time, the feed rate, the   power range, etc. For the main processing parameters, stroke, pressure, and time, there is a shortcut for direct adjustment using the touch screen. The machine's automatic repair function can automatically perform short-range repairs on this position after detecting the size where the inner diameter is too small.

 

Equipment and accessories

 

1,List: see following table 1 and 2 for details.
2,Tools necessary for machine installation.
3,Technical information: The manual includes: installation instructions, foundation diagram, electrical connection diagram, mechanical manual, electrical numerical control system manual and electrical schematic diagram, servo system maintenance manual and electrical schematic diagram, one set of product qualification certificate for each machine tool, etc. (English/Chinese)

 

Equipment installation and commissioning, quality assurance period and after-sales service

 

1,The equipment is pre-accepted before delivery, and the supplier is responsible for the reception of the buyer and completes the pre-acceptance work. When the equipment arrives at the site, the supplier will arrive at the buyer within the appointed time after receiving the buyer's notification for the installation, debugging and trial processing of the machine. The equipment installation shall be the responsibility of the supplier, who shall provide their own installation and construction tools. The supplier shall abide by the demander's company system and maintain the on-site 5S work during the installation na dconstruction process. This work will be completed within 5 days, and the trial production will be carried out once the installation and commissioning is completed, and the acceptance will be carried out according to the standard.


The supplier shall complete the training of the operator and maintenance personnel of the buyer at the buyer's site. The training time is 3 days; the trained personnel shall be jointly organized by both the supplier and the buyer to conduct theoretical and practical assessments until they meet the job requirements.


2,The quality guarantee period of the equipment is 12 months (except for consumables). During the quality guarantee period of the equipment, the manufacturer must immediately repair or replace it for free and debug it due to quality problems or failures caused by poor equipment design or production and the responsibility of other suppliers.


3,If the equipment fails during the warranty period, the seller must respond positively within 4 hours after receiving the notice from the buyer, and go to the buyer's site to deal with it or assist the buyer to solve the problem as soon as possible by telephone, video, etc.

 

Equipment inspection and acceptance criteria

 

1.Quality: first, the quality of the processed products meets the technical requirements of the buyer, secondly, the tubes are processed continuously for 3 days and the quality meets the technical requirements.
2. The electrical components used in the equipment are all high-quality products and ensure reliable operation;
3. The equipment requires stable operation, flexible control, no oil leakage, water leakage and abnormal noise;
4. The overall outer surface of the equipment is required to be smooth, bright and free of unevenness.
5. The supplier guarantees that all parts of the machine tool are brand new.

 

Buyer's own items

1. 3 barrels of honing oil (180L/barrel), the model specified by seller must be purchased during acceptance.
2. Trial honing workpiece (the dimensions within the processing range of the honing machine)
3. Honing whetstone (Seller only provides 10sets of honing stone for acceptance testing)

4: Quality assurance! Before delivering to the customer, the quality supervision department of the factory strictly controls the quality.
5: Customize specialized honing machines and tools according to customers' needs for honing special workpieces.

 

Why does the size of the hole exceed the tolerance after honing

 

(1) The honing heat is high, and the size decreases after cooling,
(2) The boring station is unstable, resulting in small dimensions due to insufficient manpower

 

What are the specific reasons for honing size deviation

 

1: Excessive honing allowance and long honing time
2: High honing speed, low reciprocating speed; Oil stone blockage, rapid feed of self sharpening honing quantity:
3: Excessive honing pressure; Insufficient coolant or poor cooling performance.
