The reverse clearance of the CNC factory live production CNC machine refers to the phenomenon where the actual displacement lags behind the commanded displacement when the feed axis direction is switched. This is due to the gap existing between the transmission components (such as screw and nut pair, bearings, gear pair, etc.) causing the actual displacement to be behind the commanded displacement. If the reverse clearance is too large, it will directly affect the processing accuracy: circular arc turning is prone to overcutting or undercutting, processing of stepped shafts results in dimensional deviations, and even leads to part scrapping. It can also cause unstable positioning accuracy of the machine tool and poor surface roughness. Therefore, it is necessary to conduct scientific investigation and handling. Then, does a large reverse clearance require manual calibration? The answer depends on the cause, size of the gap, and the status of the machine tool. It cannot be generalized.
Firstly, establish the logic of "measuring first, then processing", rather than directly starting the calibration. The first step is precise measurement: fix the dial indicator on the base surface of the slide plate or tool holder, select a feed axis, slowly move to the fixed scale and then move in the opposite direction, record the difference between the two displacements (i.e., the actual reverse clearance value); during the measurement, avoid external interference and ensure the dial indicator is firmly fixed and the movement speed is smooth to reduce human error. Generally, the allowable range of reverse clearance for CNC factory live production CNC machines is 0.01-0.02mm (varies slightly depending on the model), if the measured value exceeds this range, it is necessary to make targeted adjustments.
Secondly, determine whether manual mechanical calibration is required. Manual calibration is not a blind adjustment of components, it is only applicable to cases where the gap exceeds the limit due to mechanical looseness or insufficient pre-tightening: such as loose pre-tightening screws of the screw and nut pair, excessive axial clearance of the bearing, excessive clearance of gear meshing, etc. Such faults can be eliminated by manual adjustment of the gap. For example, for the screw and nut: first loosen the locking screw, evenly tighten the pre-tightening adjustment screw (the pre-tightening amount is controlled at 0.02mm to avoid excessive tightness and increasing transmission resistance or causing the screw to deform), and then measure the gap again; if it is a bearing problem, the thickness of the bearing end cover's spacer needs to be adjusted to eliminate axial movement, indirectly reducing the transmission gap.
The boundary of manual calibration needs to be clarified: if the reverse clearance is caused by irreversible mechanical damage such as wear of the screw or deformation of the guide rail, manual calibration can only temporarily alleviate the problem and cannot fundamentally solve it. Blind adjustment will even exacerbate component wear. Moreover, if the machine tool system supports clearance compensation (such as FANUC system 1851 parameters, Siemens system 32450 parameters), when there is still remaining clearance after mechanical adjustment, it can be compensated through parameter settings instead of relying excessively on manual operation.
At the same time, be vigilant about the misunderstandings of manual calibration: some operators only adjust based on experience without first measuring the clearance value, or apply uneven force, causing the screw to deform under force, which further increases the gap. The standardized manual calibration process should be: first measure and confirm the clearance value → investigate the mechanical root cause of the gap → make targeted adjustments to the corresponding components → measure again to verify if the clearance is within the standard, each step should be supported by data to avoid subjective misjudgment.
In conclusion, when the reverse clearance of the CNC factory live production CNC machine is too large, it does not necessarily require manual calibration: only when the gap is caused by mechanical looseness, insufficient pre-tightening, etc., and exceeds the allowable range, it is necessary to conduct standardized manual calibration; if it is irreversible mechanical damage, it should be handled by using parameter compensation or replacing components, avoiding blind operation that may cause secondary damage to the machine tool.

As industrial automation and robotic applications continue to advance, the product forms of CTLA28 linear actuators in China have become increasingly diverse. When purchasing personnel and engineers are selecting models, they often find that for the same CTLA28 linear actuator in China, products from different manufacturers vary greatly in their structural forms: there are two-finger parallel opening and closing ones, ones that rotate around a pivot point, and ones where three fingers contract simultaneously... Which structure is suitable for your application? This article will disassemble and explain in detail the five mainstream types of CTLA28 linear actuators currently available on the market, clearly presenting their structural principles, advantages and disadvantages, and the best application scenarios.
1. Parallel opening and closing CTLA28 linear actuator (most common)
Structural principle
The parallel opening and closing gripper is the most widely used type of CTLA28 linear actuator in the market. The two gripper fingertips are driven by the transmission mechanism to perform symmetrical linear opening and closing movements along a direction parallel to the gripper body. No matter where they are opened or closed, the two fingertips always remain parallel.
Advantages
Good grasping stability: Parallel fingertips mean that the contact area on both sides of the workpiece is always consistent, the gripping force is distributed evenly, and it is less likely to slip or shift
Wide compatibility with workpieces: The same pair of fingertips can be compatible with different-sized workpieces, and there is no need to frequently replace them
Simple programming: The opening and closing stroke and force control parameters are intuitive, and the debugging cost is low
Rich product line: From micro-sized (with a few grams of gripping force) to heavy-duty (with hundreds of kilograms of gripping force), there are corresponding models available
Disadvantages
The structure is relatively large: To achieve parallel movement, internal gear racks or four-bar linkage transmission mechanisms are required, and the overall size is larger than that of the angular pendulum type.
The opening and closing stroke is limited: Due to the structural constraints, the maximum opening angle is usually limited, and it may not be sufficient for particularly large workpieces.
Typical applications
3C electronic component grasping, PCB board handling, small component assembly, laboratory automation
II. Angular Pendulum-type CTLA28 linear actuator China (rotational opening and closing)
Structural principle
The two fingertips of the angular pendulum-type gripper rotate in an arc around a fixed pivot point, similar to the "pinching" action of the thumb and index finger. The motor drives the fingertips to rotate around the axis through a worm gear, worm, or gear mechanism.
Advantages
Compact structure: There is no complex parallel transmission mechanism, and the volume can be made smaller and lighter
Large opening and closing stroke: The rotational motion naturally has a large opening angle, suitable for grasping workpieces with a wide range of sizes
Relatively low cost: The structure is simple, and the manufacturing and assembly costs are low
Disadvantages
The grasping stability is not as good as the parallel type: when the fingertips make an arc motion, the angle of contact with the workpiece is changing, which is prone to uneven contact for square workpieces.
The direction of the clamping force changes with the angle: the opening and closing angle of the fingertips is different, and the force applied to the workpiece is also different, which is not conducive to precise grasping.
The fingertips are frequently replaced: different shapes of workpieces usually require custom fingertips of different shapes.
Typical applications
Grasping of bottle and can containers, picking up pipe materials and rods, simple transportation and sorting
Three, Two-finger CTLA28 linear actuator China (linear or oscillating)
Structural principle
Strictly speaking, the two-finger gripper is not an independent type, but a basic form classified by the number of fingertips. The most common parallel type and angular oscillation type mentioned above are both two-finger structures. The two fingertips perform symmetrical motion to complete opening and closing grasping.
Advantages
The structure is the simplest and the control is the most mature: the control logic of the two fingers is the most direct, and the driver algorithm is the most mature.
The product selection range is the widest: most of the CTLA28 linear actuator China products on the market are two-finger structures, and there is a large selection space.
Maintenance is convenient: there are few components, and fault detection and maintenance are simple.
Disadvantages
The grasping stability is limited by the two-point contact: for circular or irregularly shaped workpieces, the stability of the two contact points is not as good as that of three or more contact points.
Large-sized workpieces are prone to eccentricity: if the center of the workpiece is not on the centerline of the two fingertips, it is easy to cause rotation.
Typical applications
General grasping scenarios, the transportation and assembly of most standard workpieces
Four, Three-Finger CTLA28 Linear Actuator China (Self-centering Grasping)
Structural principle
The three-finger gripper has three fingertips, which are symmetrically distributed at 120° intervals. The three fingers contract or open outward simultaneously under the drive of the transmission mechanism. This structure inherently has a "self-centering" function - regardless of how the size of the workpiece changes, the center of the workpiece will always be located at the geometric center of the three fingers.
Advantages
High self-centering accuracy: The symmetrical structure of the three fingers ensures that the workpiece automatically aligns, especially suitable for grasping and assembly tasks that require precise centering
Best grasping stability: Three-point contact forms a stable triangular support, and the workpiece is less likely to slip or shift
Excellent grasping effect for circular workpieces: The three fingers simultaneously contact the outer wall of the circular workpiece, with good enveloping performance
Capable of grasping internal holes: Some three-finger grippers support reverse expansion actions, which can insert into the internal holes of the workpiece for internal support grasping
Disadvantages
Complex structure, high cost: Three sets of transmission mechanisms move synchronously, with high manufacturing precision requirements. The price is usually 2-4 times that of the two-fingered grippers of the same specification.
Poor adaptability for square workpieces: When three fingers have a symmetrical structure and grasp square or irregular workpieces, the distribution of contact points is not ideal.
Limited opening stroke: Limited by the three-finger linkage mechanism, the maximum opening angle is generally not as good as that of the two-finger gripper.
Typical applications
Motor rotor/stator grasping, flange transportation, pipe fitting internal support grasping, precise parts centering and assembly
Five. Multi-finger Bionic CTLA28 Linear Actuator China (Lively Hand)
Structural principle
The multi-finger bionic gripper is the most advanced type in the CTLA28 linear actuator China. It is usually equipped with 4-5 fingers, and each finger has multiple joints that can move independently or cooperatively. Its design is inspired by the human hand, striving to achieve the dexterous operation capabilities similar to those of a human hand at the robot's end.
Advantages
Highest operational flexibility: Can perform various complex hand movements such as grasping, pinching, holding, and pulling
Self-adaptive grasping: The multi-joint fingers can automatically fit the surfaces of different shapes of workpieces without the need to replace the fingertips
Extremely versatile: Theoretically, it can grasp almost any shape of object
Disadvantages
High cost: The multi-motor, multi-sensor, and multi-joint structure determines a high price, usually ranging from tens of thousands to tens of thousands of yuan.
Complex control algorithm: The coordinated control of multiple degrees of freedom requires extremely high computing power and algorithm proficiency for the controller.
Limited load capacity: To maintain flexibility, the finger structure is usually made relatively lightweight, resulting in a lower grasping force compared to dedicated grippers.
Reliability is still being verified: The product's maturity is relatively low, and there are not many large-scale industrial application cases.

Hardware tools should not be used without maintenance. Otherwise, their service life will be shortened. Today, we will discuss the use and maintenance of pneumatic screwdrivers in the hand pliers selection.
The hand pliers selection is mainly used for tightening assembly, in industries such as automotive manufacturing, electronics, home appliances, automotive parts production, equipment maintenance, and aerospace. Precision, reliability, and durability are the functional criteria of hand pliers selection. The quality of rotating hand pliers selection depends on six aspects:
1. The performance of the built-in pneumatic motor (rotational power);
2. The metal materials and processing methods used for transmission mechanism components;
3. The processing accuracy of components and the assembly accuracy of the tool;
4. The innovation, optimization, and improvement of tool design and production;
5. Quality control;
6. Correct and reasonable usage.
The basic six key points for the operation and maintenance of hand pliers selection: 1. Correct gas supply system: The intake pressure at the tool's inlet (not the output pressure of the air compressor) is generally 90PSIG (6.2Kg/cm^2). Both too high and too low pressures will damage the tool's performance and lifespan. The intake must contain sufficient lubricating oil to allow the pneumatic motor inside the tool to be fully lubricated (a piece of white paper can be placed at the tool's exhaust to check if there is oil stain, which should be present normally). The intake must contain as little moisture as possible. It is inappropriate if the compressed air has not been dried by an air dryer.
2. Do not dismantle the tool's parts randomly and operate. This will not only affect the operator's safety but also cause damage to the tool.
3. If the tool has minor faults or cannot achieve its original function after use, it should not be used any further. It should be immediately checked.
4. Regularly (about once a week) inspect and maintain the tool, add grease (Grease) to the bearings and other rotating parts, and add engine oil (Oil) to the pneumatic motor area.
5. When using various tools, always follow all safety regulations and operation instructions.
6. Select the appropriate tool for work. Tools that are too large are likely to cause work injuries, while tools that are too small are likely to cause damage to the tool.
