Dalian THK manufacturer analysis: What issues need to be paid attention to when disassembling linear guides?

THK linear guides are high-precision motion components that require careful handling during installation and removal to prevent unevenness and loss of precision. What are some common problems encountered when disassembling linear guides? What issues need attention? 1. The linear guide slider has plastic parts at both ends and sides. Do not use hard tools to strike them during installation. During trial operation after installation, do not allow any objects to collide with it. If the plastic parts are broken, the balls will roll out, and the slider will fall. 2. It is strictly forbidden to disassemble the components of the linear guide at will, as this will affect the precision and flexibility. It is strictly forbidden to arbitrarily add non-compliant balls to the linear guide. 3. Do not remove the slider from the linear guide unless necessary. If removal is necessary, align the auxiliary linear guide first before removing the slider. 4. When cleaning, make sure to let the lubricating oil dry before adding more lubricating oil. Do not operate without lubricating oil. Dalian THK manufacturer, Maoming Machinery, specializes in THK guide sliders, linear guides, ball screws, precision worktables, gears and racks, and industrial shock absorbers.

What are the important roles of Dalian clamping device manufacturer HTPM clamping devices in rolling linear guide pairs?

Clamping devices are crucial components in rolling linear guide systems, ensuring quick braking and safe operation. They guarantee the safe and reliable operation of CNC machine tools and are suitable for workpiece fixation, positioning, and vibration prevention. Clamping devices consist of a main body, power unit, clamping unit, and contact unit, and are high-performance functional components used with LGR roller linear guide systems. In normally open clamping devices, there is a certain gap between the brake block and the guide surface. When braking is needed, a pneumatic cylinder drives a wedge block to bring the brake block and guide surface into contact, achieving braking through the strong frictional braking force provided by the wedge block. Normally closed types also have an emergency braking function in case of power failure. Normally closed clamping devices are often used to fix and precisely position the moving work platform of the guide, reducing vibration and improving overall rigidity. Features: 1. Safe and reliable, with strong clamping force for workpiece fixation, positioning, and vibration prevention. 2. Fast response, preventing Z-axis drops and collisions to protect the machine tool. 3. Easy installation, without requiring changes to the workpiece dimensions. 4. Durable, with nickel-plated surface for good rust prevention. 5. Novel design, avoiding rigid impact during clamping.

Dalian Detai Ke buffer manufacturer, Maoming Precision Machinery, explains the correct installation method for Detai Ke buffers.

The DSC series hydraulic heavy-duty buffer adopts a leading German-designed new airbag buffer reset structure, greatly expanding the buffer capacity (up to 930kJ) and stroke range (up to 1500mm). The reset structure of the DSC series replaces the mechanical reset spring with high-pressure nitrogen, effectively shortening the length of the buffer. During buffering, the hydraulic oil flows through multiple throttle holes, generating viscous damping force, converting the impact energy into heat dissipation. The hydraulic oil discharged from the multi-stage throttle holes compresses the volume of the airbag; when the load is removed, the hydraulic oil returns to the inner oil cavity under the pressure of the airbag, pushing the piston rod to reset. The DSC series hydraulic heavy-duty buffer meets global industrial safety standards such as OSHA, AISE, CMMA, DIN, and FEM. Compared with the DTH series, the DSC has a similar structure and working principle, but due to the advanced airbag reset design, the DSC series has lower peak reaction force and smoother buffering effect, making it well-applied in amusement equipment and automated warehousing industries involving personal safety. Installation Requirements: 1. The buffer needs to be fixed to the ground or mechanical equipment via flange. The fixing must be firm and reliable without any shaking; If fixed on mechanical equipment, ensure the rigidity and strength of the fixed position, which must not shake or deform due to impact; any form of loose fixing or support is prone to damage the buffer, thus failing to provide effective protection. 2. When horizontally installed, ensure that the direction of the buffer piston rod coincides with the impact direction of the load, and the linear included angle must be less than 0.5° (this is extremely important, lateral force will greatly affect the safety and lifespan of the buffer); also ensure that the impact contact surface between the load and the buffer is completely perpendicular to the direction of the piston rod; for buffers with a stroke greater than or equal to 300mm, front flange installation or double flange installation is recommended; for buffers with a stroke greater than or equal to 600mm, double flange installation (or an additional fixing bracket added by the customer) is strongly required. 3. When vertically installed, ensure that the direction of the buffer piston rod coincides with the impact direction of the load, which is usually free fall motion. Ensure the verticality of the buffer (the included angle between the piston rod and the vertical direction must be less than 0.5°. This is extremely important, lateral force will greatly affect the safety and life of the buffer); also ensure that the impact contact surface between the load and the buffer is completely perpendicular to the direction of the piston rod; for buffers with a stroke greater than or equal to 300mm, rear flange installation or double flange installation is recommended; for buffers with a stroke greater than or equal to 600mm, double flange installation (or an additional fixing bracket added by the customer) is strongly required. 4. For harsh working environments, such as a lot of dust, impurities, and rainwater, it is recommended to add a piston rod protective cover to the buffer when ordering to extend the service life. TECHNICAL DATA Compact design, high energy absorption, stroke up to 1500mm, suitable for various applications. The DTH series is a customized product, requiring customers to provide detailed application parameters. Through professional calculations and precise design, we provide customers with the most suitable product to achieve the ideal buffering effect. The design complies with OSHA, AISE, CMMA standards and DIN, FEM safety regulations. Compared with DTH buffers, DSC has lower peak buffering force and smoother buffering effect, and is widely used in amusement equipment industries involving personal safety. The outer cylinder is made of special corrosion-resistant epoxy spraying, and the piston rod is hard chrome-plated, so DTH products can be used in outdoor or marine high-corrosion environments. Wider temperature range, standard model (-10℃~+80℃), special model (-40℃~+120℃) A variety of accessories meet the various installation and use needs of customers. Maintenance Requirements: 1. Regularly check the surface of the piston rod for dirt and other impurities. If any, please wipe them clean. 2. Regularly check whether the piston rod of the buffer is fully extended; if not fully extended, there may be pressure loss, please contact Detec for further inspection; if the customer needs to add pressure by themselves, please confirm with Detec. 3. Regularly press the piston rod along the axis of the piston rod to see if there is any pressure loss inside the buffer; if there is pressure loss, the handling method is the same as item 2. 4. Regularly check the appearance of the buffer for any obvious oil leakage; if any oil leakage is found, stop using the buffer and contact Detec for further inspection. 5. For frequently used buffers, regularly check whether the buffer installation is still reliable and firm (e.g., check if the flange fixing bolts are loose). 6. For frequently used buffers, regularly check the included angle between the direction of the piston rod and the impact direction of the load to see if it has increased (exceeded 0.5°). Amusement equipment Stacker Port machinery Crane Heavy-duty emergency protection Papermaking machinery Drop hammer, etc. The buffer must be installed firmly and reliably, fixed and tightened with nuts at both ends, and cannot shake; unstable installation will cause the buffer to break when hit, and in severe cases, it will cause equipment damage. When installing, pay attention to the use of the stroke. Adding a sleeve or leaving a 1mm margin will help extend the service life of the buffer. Adjustment and Use Confirm that the adjustment knob is at position 0, correctly install the buffer on the work station, and start the impact. Judge the buffer by the impact sound and careful observation. If there is no obvious deceleration during the entire buffering stroke and there is a loud "bang" at the end of the buffering stroke, then the damping force is too small. Please adjust the scale of the buffer to position 1 and retest; if there is no improvement, continue to adjust to position 2, 3... If when adjusted to position X, the moving load can stop quickly and smoothly, and there is only a "poof" sound during the whole process, then the ideal buffer effect has been achieved. Use the L-shaped wrench in the product package to lock the locking screw and maintain this scale. Conversely, if the front or middle section of the buffering stroke suddenly decelerates and makes a loud "bang", then the damping force is too large, and the scale should be reduced and retested. If repeated adjustments and tests cannot achieve the ideal buffering effect, then there is a problem with the buffer selection, and it may be necessary to replace a larger model for testing. It is also recommended to reconfirm the selection.

Dalian Kate htpm manufacturer Maoming Machinery Co., Ltd. analyzes the performance characteristics of the LGS series single circular arc linear guide.

The LGS single-arc linear guide belongs to the high-self-aligning series and is designed for small and medium-load machine tools with large installation errors, friction sensitivity, or high sealing and dust-proof requirements. LGS series features: 1. Self-aligning capability The circular arc groove is a DF (45º-45º) combination, which has self-aligning capability. Even if the mounting surface has a certain deviation, it can be absorbed by the internal guide, resulting in high-precision, smooth and stable linear motion. In general, the accuracy and surface quality requirements of the mounting surface do not need to be very high, and fine planing or fine milling can be used. If the guide is required to achieve very high accuracy after installation, the mounting surface must also have high accuracy. 2. High rigidity in all aspects The LGS series guide uses a four-row circular arc groove, and the 45-degree contact angle design of each groove ball makes the load-bearing capacity of the slider uniform in the up, down, left, and right directions. Pre-pressure can be applied to improve rigidity as needed. Kate Precision Machinery has measured the rigidity of the LGS series guide using its self-developed rigidity measuring machine, and the rigidity has reached the same level as that of famous foreign brands. 3. Smooth and stable movement The optimized design of the transition area at both ends of the slider raceway effectively reduces the vibration caused by the entry and exit of the steel balls into the raceway. 4. High sealing performance The LGS guide uses a new type of double-lip sealed end cover, which can further improve the dust-proof and anti-pollution capabilities compared to traditional sealed end covers. 5. Good interchangeability The LGS series guide is precision-ground, and the accuracy of the guide rail and slider grooves is strictly controlled, achieving a certain level of product interchangeability. 6. Chrome-plated guide rails with corrosion resistance The LGS guide provides corrosion-resistant chrome-plated guide rails. 7. Locking and unlocking guide rails

Dalian THK genuine imported guide rail slide block HSR25C4SS+558L, available from Dalian Maoming!

The HSR series products are characterized by high rigidity and durability. THK linear guides HSR series steel balls roll along the LM rail and LM slider via four rows of rolling surfaces; the steel ball row circulation movement is achieved through end plates assembled on the LM slider. Because the steel balls are held by retainer plates, the steel balls will not fall off even if the LM slider is pulled out from the LM rail, except for the HSR8, 10, and 12 types. Each steel ball row is designed to be configured at a contact angle of 45 degrees to allow the four directions of action on the LM slider to have the same rated load, so it can be used in any posture. Moreover, because uniform pre-pressure can be applied, the friction coefficient is kept low while rigidity is enhanced. In addition, stable high-precision linear motion can be performed. THK linear guide HSR-A type is a type in which the flange part of the THK linear guide slider is subjected to thread machining. THK linear guide HSR-B type is a type in which through-holes are machined in the flange part of the THK linear guide slider, which can be used in cases where through-holes for assembling bolts cannot be drilled on the worktable. THK linear guide HSR-R type is a type in which the width (W) of the THK guide slider is reduced, and thread machining is performed, making it ideal for miniaturized designs. THK linear guide HSR-YR type: When using two THK linear guide units facing each other, it used to take a lot of time to process the worktable, and difficulties were encountered in achieving the required precision and adjusting the clearance. However, since the HSR-YR type has threaded holes on the side of the THK linear guide slider, the structure is simplified, the number of processes is greatly reduced, and the processing accuracy is significantly improved. THK linear guide HSR-LA type has the same cross-sectional shape as the THK linear guide HSR-A type, but the overall length (L) of the THK guide slider is extended, increasing the rated load. THK linear guide HSR-LB type has the same cross-sectional shape as the HSR-B type, but the overall length (L) of the THK linear guide slider is extended, increasing the rated load. Among all THK linear guides, the non-retainer type linear guides have high usability and can be used in a wide range of conditions/environments, from ordinary to extreme. For example, Dalian THK Maoming Precision Machinery believes that as long as the correct options are selected, it is possible to use them even under conditions such as vacuum and high temperature where resin parts cannot be used.
