Equipment for ball joint repair is very popular today. Why? I propose to sort this out together.
The quality of roads, unfortunately, is far from always meeting the standards that we would like to see. This is well known not only to all drivers, but also to passengers. The first thing that suffers from this is the ball joints, which during the movement of the vehicle experience destructive effects from all sides. In the picture, the zones of maximum load exerted on the nodal connection are marked in red:
Sectional picture of a ball joint The node itself consists of two elements:
Sleeve; Swivel ball. Between them is a special polymer, which:
It softens the force of ball impact on the sleeve; Minimizes the effect of friction of metal parts against each other. All problems, including wrest the wheel on its side, are possible if the polymer liner is worn, which is inevitable over time.
Wrest the wheel-turned wheel example SJR technology avoids such a catastrophic outcome and, with timely intervention, maintains the performance of the ball joint almost endlessly. How it works? Let’s figure it out.
There are two methods for ball support recovery using SJR equipment:
Removal of old polymer Drill a hole in the case of the sleeve; Burn the remains of the old polymer with a gas burner; In the extruder, melt a new batch of polymer Under high pressure, the molten polymer is injected into the cavity between the ball and the sleeve through a hole previously made. The solution fills all the voids, solidifies and forms a new liner, not inferior in its characteristics to the factory insert. 2. Demountable
The collapsible method is more complicated and longer, but also more efficient. It is used when there is significant wear on the ball joint, the appearance of rust on the ball.
In this case, the repair begins with the following steps:
Cut the sleeve in half. Polish the ball. Brew sleeve. The final steps are the same as in the previous method.
The advantages of using this technology are quite obvious. It:
Economic benefit. Recovery is always cheaper than buying a new part; Universality. Suitable for the restoration of any ball joints and steering tips; The compact dimensions of the necessary equipment. Even the largest machine can easily be rearranged from one place to another by one person and can be comfortably located not only in a spacious car service, but also in a small garage workshop; Cheap consumables. Variants of suitable equipment
The operations described above can be carried out using various equipment that differs from each other:
At the cost of; In size; Power; In level of automation. We will briefly consider four models presented on our website.
Equipment for ball joint repair – Light version
The simplest version of equipment for recovery of ball joints and steering includes:
An extruder for heating and forming a polymer consistency; Three interchangeable adapter fittings, with which the solution is charged under pressure into the problem area; Remote thermometer that allows you to monitor the temperature of the detail at a distance; Five polymer rods, shipping container and instructions. The pressure of such a device is only 25 kg / cm2 , and it needs a compressor with a capacity of 7-10 atm at the service station. The set is quite economical in terms of financial expenses, as it costs only 180 $, and is compact, but quite demanding on additional equipment and labor costs from the operator.
Equipment for ball joint repair – Modification 1
This model is reinforced:
A more powerful piston capable of creating pressure up to 80 kg / cm 2 ; The control unit simplifies the operation of the device. But it also costs a little more: 370 $.
Equipment for ball joint repair – Modification 2
In the next modification, the piston power reaches 100 kg / cm2 . But its main advantage is the presence of a high-quality mechanism for centering the ball joint. Such an addition allows during the introduction of the molten polymer to firmly and reliably fix the part in one position. This facilitates the work of the operator, and the quality of the result improves.
The cost of such equipment reaches 640 $.
Equipment for ball joint repair – SJR 3 machine
The SJR 3 machine will cost 1 180 $ for your workshop, but will eventually work out every cent invested and will bring considerable profit from above. This is a fully automated unit, equipped with all technological advances.
Here are just a few of its most significant advantages:
The created pressure – 240 kg / cm 2 ; Full control of the melting process; Automatic nozzle feed; Mechanical clamp and centering of the ball joint; Robust cast housing. Conclusion
The restoration of ball joints and steering tips using SJR technology is a technologically advanced, profitable and easily feasible process in the presence of the necessary equipment. It is noteworthy that such equipment is available in different price categories, so that every car repair shop can make the optimal choice for itself.

(1.2) Productive Category
(1.3) Process Planning
(2) The instruction for benchmark
(3) CNC lathe machining Processing Cushion
(4) Scope of application
(5) Types of equipment
(6) China CNC lathe machining manufacturers
3. CNC lathe machining fundamental process
(i) Productive Process
Types of equipment productive processes are the process for making the products from raw material (unfinished blanks).
Types of equipment productive process include raw material transit and storage,
CNC lathe machining production preparing, unfinished blank making,
Precision parts’ CNC lathe machining and heat treatment, precision parts’ assembling, test, painting, and package, etc.
In the productive process, there is a technical process.
Technics process is the process to change the workpiece’s shape, dimensions, positions, and character, etc, and make the workpiece to finished precision parts or unfinished blanks.
Technics process is a key part of the productive process.
Technics process includes casting, forging, stamping, welding, CNC lathe machining, assembling, etc.
Types of equipment production technics process include precision parts’ equipment production technics process and types of equipment assembling technics process.
Others are auxiliary processes, for example, transit, storage, power supply, equipment repair, etc.
Technics process also consists of one or several tactic processes, one process consists of several steps.
A process is an elementary unit for types of equipment production technics process.
Process definition is the technics process, that one worker (several workers) finish production continuously on one machine (or one position) for the same workpiece (or several workpieces).
The main characteristic of the process is that it doesn’t change the workpiece, types of equipment, or operator, and continuously.
The step is based on the same CNC lathe machining surface, the same CNC lathe machining tools and the same volume of feed
The Feed is a working process, which is a step for production finish on the workpiece’s surface by tools.
When making the types of equipment’s technics process, you have to make sure how many steps the workpiece needs and the sequence.
Technics flow is a simple process of key processes and sequences.
Technics flow is very important for making technics process,
Its function is to select the correct processing method for each surface, make sure the sequence of each surface, and the number of processes.
(ii) Productive Category
Productive Categories are usually divided into three categories,
a. Single workpiece production:
Manufacture different structures’ and dimensions’ workpiece separately, and seldom repeat. b. Batch production:
Manufacture the same structure and dimensions’ workpiece among one year, there is some repeatability in the manufacturing process. c. Mass production:
The quantity is huge, manufacture the same process in the same place. (iii) Process planning
1. Every technological procedure is planned to make sure the quality of precision parts (types of equipment assembling), And reaches all the specifications as the drawing requests. 2. The technological procedure should have high productivity, The products made by technological procedures should be launched as fast as possible. 3. Try our best to decrease the production cost 4. Pay attention to reduce the intensity of labor to ensure production safety. Raw data
1.Assembling drawing, precision parts drawings
2.Inspection quality standard
3.Yearly production program
4.Conditions of manufacture, including types of equipment and specification, performance and current status, workers’ technological level, power and water supply, etc.
5.Process planning, manual, and standard.
6.Advanced manufacture data
1. Analysis product’s assembling drawing and precision parts’drawings.
2. Confirm the blank
3. Make technics flow and ensure the position reference surface
4. Prepare the types of equipment according to each preocess
5. Prepare the blades, jigs, measuring implement, and auxiliary tools
6. Ensure the specification and inspection method for each process
7. Ensure the allowance for CNC lathe machining, calculate the size and tolerance
8. Ensure the cutting parameters
9. Ensure the production time
4. The instruction for benchmark of CNC lathe machining
Precision part consists of several surfaces,
When analyzing the relative relation of the surfaces, you must confirm a benchmark.
Benchmark is a dot, line, and surface to confirm the part’s dot, line, and surface.
According to the different functions of the benchmarks, there two categories,
One is the design benchmark, the other is the technical benchmark.
1. Design benchmark:
The benchmark to confirm the dots, lines, and surfaces on the drawings 2. Technics benchmark:
The benchmark for production and assembling. 3. Assembling benchmark:
The benchmark for confirming the parts’ position in the products when assembling 4. Measure benchmark:
The benchmark for inspecting the sizes and position 5. Locate benchmark:
The benchmark for CNC lathe machining. 5. CNC lathe machining Processing Cushion
When the blank is made to finish the product, you will be machining out the metal layer,
The total of the metal layer is called the total processing cushion.
The metal layer of every process is called process cushion.
As to the circle and hole, the processing cushion is on the diameter, called symmetry cushion.
The reason, why the workpiece has the processing cushion, is to CNC lathe machining out the tolerance or defect on the workpiece from the last process, for example,
The cold layer of casting parts, bubble hole of casting parts, the sand layer of casting parts.Oxide skin of forging parts, surface crack of forging parts, decarburized layer of forging parts.
The surface roughness of CNC lathe machining, etc.
The processing cushion can increase the precision and roughness of workpieces.
The volume of processing cushion will affect the product quality and production efficiency.
If the processing cushion is too big, it will increase the CNC lathe machining sum of labor,
Decrease the production efficiency, increase the loss for raw material, tools and power,
And increase the production cost.
If the processing cushion is too small, the tolerances and defects from the last process cannot be removed,
The tolerances for loading and unloading cannot be removed too.
The principle is selecting the smallest processing cushion based on high quality.
Scope of application
1. Different metal parts CNC lathe machining
2. Fabrication, box structure, metal structure
3. Titanium, high-temperature alloy, nonmetal CNC lathe machining
4. Design and manufacture of wind tunnel combustion chamber

3 Levels of manufacturers in China
During the development of more than 50 years, there are 3 levels of manufacturers in China,
10% is a top-quality manufacturer, 20% middle quality manufacturer, and 70% low quality & cheap price manufacturer.
The global markets
At present, many markets are growing all over the world, such as Poland, Czech, Turkey in Europe, Thailand, Vietnam, the Philippines, India in Asian, Brazil in South America.
Compared to these new growing markets, China has many advantages based on high quality.
China CNC lathe machining market developing
In the past, everybody think made in China is for cheap and low quality,
It’s because China doesn’t have high precision types of equipment and skilled workers,
It looks like these new growing markets very much.
But now, 10% top quality manufacturer is fully changed,
Their core advantage is high quality, they compete with European and North American famous factories.

If you’re feeling the summer heat, so is your car’s battery. Contrary to popular belief, summer highs rather than winter lows pose the greater threat to battery life, according to the non-profit Car Care Council.
“When most motorists think of dead batteries that cause starting failure, they think of severe winter weather, but summer heat is the real culprit,” said Nathan Perrine, executive director, Car Care Council. “Many battery problems start long before the temperatures drop. Heat, more than cold, shortens battery life.”
Sooner or later all batteries have to be replaced. Excessive heat and overcharging are the two main reasons for shortened battery life. Heat causes battery fluid to evaporate, thus damaging the internal structure of the battery. A malfunctioning component in the charging system, usually the voltage regulator, allows too high a charging rate, leading to slow death for a battery.
To get the most life out of a battery, the Car Care Council suggests the following simple steps:
Be sure the electrical system is charging at the correct rate; overcharging can damage a battery as quickly as undercharging. If your battery is the type that needs to be topped off, check it regularly, especially in hot weather. Add distilled water when necessary. Always replace a battery with one that’s rated at least as high as the one originally specified. Keep the top of the battery clean. Dirt becomes a conductor, which drains battery power. Further, as corrosion accumulates on battery terminals it becomes an insulator, inhibiting current flow. Driving habits such as frequent engine on/off cycles will cause more wear on the starter than a simple back and forth to work. Other factors include driving and weather conditions, mileage, vehicle age and excessive electrical draws like in-vehicle entertainment systems. Check the battery if you notice headlights and interior lights dim, accessories that fail to operate, or the “check engine” and/or battery light illuminated.
