What should I pay attention to when buying second-hand Shadick AQ360L slow walking silk?
When purchasing second-hand Shadick AQ360L slow walking silk, it is necessary to consider the equipment condition, performance testing, relevant information, etc. to ensure that the purchased equipment meets the requirements and has reliable quality. The specific precautions are as follows:
1. Equipment condition inspection
-Appearance inspection: Check the appearance of the machine tool for obvious bumps, scratches, paint peeling, and other damages, and whether the body is deformed. Check whether the workbench is flat and free of defects such as wear and tear, as the flatness of the workbench directly affects the machining accuracy.
-Internal component inspection: Open the machine tool protective door and electrical cabinet to check whether the internal electrical components and circuits are neat, and whether there are aging, damage, short circuits, and other issues. Check the wear of transmission components such as screws and guide rails. If the screws and guide rails are severely worn, it will lead to a decrease in the positioning accuracy and repeat positioning accuracy of the machine tool. At the same time, check whether there is corrosion, leakage, and other phenomena in the working fluid system components such as the water tank and pump.
-* * Accuracy testing * *: Use professional testing tools such as laser interferometers, ball bar instruments, etc. to test key accuracy indicators such as positioning accuracy, repeat positioning accuracy, perpendicularity, parallelism, etc. of the machine tool. Request the seller to provide a precision testing report for the machine tool to understand the accuracy deviation of the machine tool in various coordinate axis directions. You can also observe whether the machining accuracy meets your production needs by actually processing some simple specimens.
-System check: Understand whether the version and functions of the control system meet the processing requirements, check whether the buttons, knobs, etc. on the operation panel are sensitive and effective, whether the display screen is clear, and whether there are any display abnormalities. At the same time, check whether the drive system of the machine tool is working properly, whether the motor is running smoothly, and whether there are any abnormal noises and vibrations.
2. Performance testing
-Cutting speed test: Run some standard cutting programs on the machine tool to observe whether its actual cutting speed matches the performance indicators specified in the equipment manual. If the cutting speed is significantly lower than the standard value, it may be due to problems with the pulse power supply, electrode wire drive system, etc. of the machine tool.
-Surface quality testing: Process some specimens with high surface quality requirements, such as mirror molds, and then use tools such as surface roughness measuring instruments to detect the roughness of the processed surface. If the surface roughness does not meet the expected requirements, it may be due to unreasonable discharge parameter settings of the machine tool, poor performance of the working fluid system, or problems with the quality of the electrode wire.
-* * Functional integrity testing * *: Test each function of the machine tool one by one, such as automatic threading function, multiple cutting function, taper machining function, etc., to ensure that all functions can operate normally. Check whether the accessories of the machine tool are complete, such as fixtures, electrode wire reels, filters, etc., and confirm the quality and applicability of these accessories.
3. Equipment history and usage
-* * Duration and frequency of use * *: Inquire about the age and average daily usage of the equipment to understand the approximate degree of wear and tear. Generally speaking, equipment with shorter service life and lower frequency of use has relatively less wear on its components, and the overall performance of the equipment will also be better.
-* * Maintenance Record * *: The seller is required to provide detailed maintenance records to understand the types of equipment failures, repair locations, and repair times that have occurred in the past. Through maintenance records, it is possible to determine whether there are any hidden faults in the equipment that are difficult to solve, as well as whether the maintenance and upkeep of the equipment are timely and in place.
-* * Processing object * *: Understand the material types, workpiece shapes, and precision requirements that the equipment mainly processed before. If the equipment has previously processed workpieces with high hardness and complex shapes, and requires high machining accuracy, the wear of the equipment may be relatively large, and the performance and accuracy of the equipment need to be checked more carefully.
4. Transaction related matters
-* * Price Evaluation * *: Before purchasing, consult professional equipment evaluation agencies or personnel by consulting the price information of similar second-hand equipment in the market, and make a reasonable evaluation of the price of the equipment to avoid buying at a high price.
-Contract Signing: Sign a detailed purchase contract that specifies the model, configuration, price, delivery time, after-sales service, and other terms of the equipment. Specify the acceptance criteria and methods for the equipment in the contract, as well as the solutions for any problems that may arise during the acceptance process.
-* * After sales service * *: Understand whether the seller can provide after-sales service for a certain period of time, such as equipment installation and commissioning, training, troubleshooting, etc. Inquire about the response time and service fees of after-sales service to ensure timely and effective support in case of equipment problems.
In addition, it is best to choose a seller with a certain reputation and word-of-mouth when purchasing second-hand equipment. If necessary, the seller can be required to provide relevant documents such as the original purchase invoice and certificate of conformity of the equipment to ensure its legality and reliable source.

Boring Machine Bore Diameter: How to Choose the Right Machining RangeChoosing the correct boring machine bore diameter starts with the workpiece, not the machine catalogue. The finished bore, existing hole condition, access length and material determine whether a machine can complete the job efficiently. A quoted maximum diameter alone does not show whether the machine can enter the smallest hole or maintain a practical setup across the full machining range. Start with the workpiece and the finished bore Record the smallest and largest bore diameters that the machine must produce. Also note whether the hole is a through bore, blind bore, stepped bore or aligned set of holes. Measure the available access around the workpiece and the distance from the mounting position to the bore centerline. The minimum bore diameter must allow the boring bar, cutting tool and any required support components to enter the hole with safe clearance. The maximum bore diameter must include the actual cutting diameter required after considering the existing hole, machining allowance and finishing pass. If a job involves several bore sizes, use the complete range rather than selecting the machine from the largest size only. Use the real boring machine working range Workpiece condition Range to verify Why it matters Small existing hole Minimum tool and bar entry diameter Determines whether the tool can reach the bore without interference. Large repair bore Maximum finished cutting diameter Confirms that the machine can remove the required material and finish the bore. Deep or offset bore Boring bar length and support position Controls reach, clearance and the usable portion of the diameter range. Stepped or multiple bores Complete diameter sequence Shows whether one configuration can cover the job without repeated changes. The usable boring machine working range is narrower than a headline range when the workpiece requires a long reach, large material removal or restricted access. Confirm the machine's operating diameter at the required boring bar length, because a configuration suitable for a short bore may not provide the same practical capability at greater depth. Match boring bar length, tooling and material Boring bar length should be based on the distance from the mounting point to the deepest cutting location. Select the shortest bar that reaches the required position while preserving clearance. Excessive length can reduce rigidity and limit practical cutting conditions, especially in hard steel or interrupted repair surfaces. Tool selection also affects the usable bore range. Small diameters may require compact cutters and suitable insert clearance; larger diameters may require a different bar, cutter arrangement or support method. Cast iron, carbon steel, alloy steel and other materials can require different cutting tools and machining approaches. These choices should be confirmed together with the diameter and reach rather than treated as separate specifications. Submit actual dimensions for configuration confirmation Before ordering, provide the supplier with the smallest and largest finished bore, existing bore sizes, bore depth, workpiece material, machining allowance, access restrictions and required bore locations. A drawing or clear dimensional sketch allows the supplier to confirm the machine range, boring bar length and tooling configuration for the actual repair or production task. FAQ Is the maximum bore diameter enough for machine selection? No. The minimum bore, required reach, cutting allowance and tool clearance are equally important. A machine may reach the largest diameter while being unsuitable for the smallest hole or deepest section. How does boring bar length affect the machining range? A longer bar extends reach but can change the practical working range because access, rigidity and tool clearance become more restrictive. Confirm the diameter range at the required reach. What information should be sent for a bore range check? Send the real workpiece drawing or dimensions, finished bore range, existing hole sizes, bore depth, material, allowance and access conditions. These details support configuration confirmation before purchase.

Boring Machine Applications in Construction Equipment RepairWhen a pin joint develops play, replacing the pin alone may not solve the problem. Wear can leave the housing bore oval, tapered or out of alignment. A boring machine for construction equipment repair restores the bore so the joint can be fitted with a correctly sized pin or bush. This work is often performed on the machine in the field when removing a large component would add substantial downtime. Where bore wear occurs on construction equipment Repeated articulation, impact loading, inadequate lubrication and contamination can wear the bores that support pins and bushes. The repair target is the damaged joint bore, not simply the visible pin. Before machining, the technician needs to identify the joint layout, access, material condition and the relationship between connected bores. Equipment Typical bore Repair purpose Excavator Boom, arm and bucket pin bores Restore pin fit and joint alignment Loader Lift-arm and bucket pivot bores Correct wear at heavily cycled pivots Backhoe Dipstick, boom and stabilizer pin bores Re-establish fit across linkage joints Crane Boom and linkage pivot bores Address wear at structural articulation points Hydraulic equipment Cylinder-end and mounting pin bores Restore the connection between cylinder and structure How boring repair addresses the damage Construction equipment boring repair typically starts with inspection and measurement. The repair team checks bore diameter, roundness, wear pattern and alignment with related bores. If the housing is suitable for repair, a portable line boring setup machines the damaged bore to a controlled, consistent diameter. Depending on the repair plan, the bore may then receive a bush, or be finished to suit the specified pin or bearing arrangement. Where two or more bores form one pivot line, their alignment matters as much as the individual diameters. Machining them in a common setup can help restore the intended axis. The required dimensions and fit should come from the equipment specification or an agreed repair drawing; they should not be assumed from the pin size alone. Field conditions shape the repair plan Access, nearby structures, available setup space and the condition of the surrounding material affect whether on-site boring is practical. Cracks, severe distortion, damaged welds or a bore near a highly loaded structural area may require additional inspection or a different repair sequence. The machine must also be isolated and securely supported before work begins, following site and equipment safety procedures. For a field assessment, document the machine and joint location, report the symptoms, and provide measurements or photographs where available. Confirm whether connected bores need to be machined on the same axis, whether a bush will be installed, and what final fit is required. These details help establish a realistic repair scope before equipment is mobilized. Frequently asked questions Which excavator parts commonly need bore repair? Boom, arm and bucket pin joints are common locations, as are other pivot connections showing looseness or uneven wear. Inspection determines whether the bore, pin, bush or several parts need attention. Can loader pivot bores be repaired on site? Often, but feasibility depends on access, setup conditions, damage severity and the required machining sequence. A site assessment can establish whether portable boring is appropriate. Does every worn bore need a new bush? No. The repair method depends on the equipment design, bore condition and specified fit. Confirm the intended finished dimensions and component arrangement before machining.

Boring Machine Cost Guide: What Affects the Price of Industrial Equipment?Two boring machines intended for similar repair work canreceive very different quotations because the price reflects more than the machine’s basic size. Machine type, working range, drive power, accuracy requirements, tooling and included automation all affect the final configuration. To compare a boring machine price accurately, compare the scope of supply and the job requirements, not just the headline figure. What drives the quotation? Price factor Why it affects cost Details to specify Machine type and setup Portable systems and larger stationary equipment have different structures and intended applications. Equipment type, work location and setup constraints Bore size and machining range Required diameter, bar length and travel determine the working envelope and compatible components. Minimum and maximum bore diameter, machining length and access Power and duty Drive requirements depend on the material, cutting conditions and expected workload. Workpiece material, typical jobs and operating frequency Accuracy and tooling Accuracy requirements and the tooling package influence component selection and what must be supplied. Required results, cutters, mounts and other tooling needs Automation and customization Controls, optional functions and non-standard configurations add scope to the build. Required automation, special interfaces and quantity Configuration matters more than a bare price A lower-priced machine may have a narrower machining range, fewer included tools or less automation. A higher quotation may include a broader configuration or options that are unnecessary for a particular job. Neither price alone establishes suitability. For a portable boring machine price comparison, check that the quoted setup can reach the bore, fit the available work area and perform the required operation. Accuracy should also be described in terms of the work to be done. Share the required result and relevant workpiece details so the supplier can quote a configuration against the application. Avoid comparing quotations that assume different tooling, accessories, automation or customization. Prepare information for a useful quote For a meaningful boring machine cost estimate, provide the bore diameter range, machining length, material, workpiece or equipment details, site access constraints and expected operating frequency. List required tooling, accuracy expectations, automation and any special mounting or interface requirements. Include the purchase quantity and identify which accessories should be included. Ask suppliers to show the proposed configuration and included items in the quotation. This makes differences easier to trace and helps prevent a low initial figure from omitting components needed for the intended work. Submit the same job information to each supplier when comparing offers. Frequently asked questions Why is one boring machine much cheaper than another? The machines may differ in type, working range, power, included tooling, accuracy-related configuration, automation or customization. Compare the quoted scope against the same application before judging the difference. What information is needed to quote a boring machine? Provide the required bore diameters and machining length, material, workpiece and site constraints, expected use, accuracy needs, tooling and automation requirements, customization details and order quantity. These details help suppliers quote a configuration suited to the job.
