Precautions for Clamping Workpieces and Tools in the CNC Machining Center

Precautions for clamping workpieces of the CNC machining center

  • When clamping the workpiece, pay attention to the position of the datum and ensure that the bolt on the pressing plate is of appropriate length. Also, be careful not to over tighten the screws when locking the foot.

  • Generally, copper parts are processed using locking plates. Before starting the machine, check the number of materials to be processed against the program list, and ensure that the screws on the receiving plate are tightened.

  • For situations where one copper material is received from multiple boards, ensure that the direction is correct and that the processing of each copper material does not interfere with each other.

  • When clamping the workpiece, pay attention to the dimensions of the workpiece as specified in the program list. The format for the size of the workpiece is XxYxZ. Also, if there are separate parts, verify that the graphics in the program list match with the separate part graphics, and pay attention to the direction and placement of the X and Y axes.

  • When clamping the workpiece of the CNC processing center, check if the dimensions of the workpiece match the specifications in the program list. DEED cnc machining center factory suggests that if there are separate parts, also verify if the sizes in the program list match with the separate part sizes.

  • Clean the workbench and the bottom of the workpiece prior to putting the workpiece on the machine. Use an oilstone to remove burrs and damaged areas on the machine table and workpiece surface.

  • When setting the datum, ensure that the datum will not be damaged by the cutter. If necessary, communicate with the programmer. If the bottom of the workpiece is a square pad, align the datum with the position of the square pad for balanced stress.

  • If using a collet chuck to clamp the workpiece, know the depth of the tool and avoid clamping the tool too long or too short.

  • Screws must be located within the T-block, and not just part of the thread. If screws need to be connected, the upper and lower screws must each use half of the joint thread, and the threaded bolts on the pressing plate must be fully used without leaving any unused threads.

  • When setting the Z depth value, check the touching point on the program list and the maximum Z-point value. After entering the data into the machine, verify again.

Precautions for clamping tools of the CNC machining center

  • Ensure that the tool is clamped tightly and not too short in the tool holder.

  • Before each tool change, check if the tool meets requirements. The length of the tool change should be determined according to the depth of processing specified in the program list, and should generally be 2 mm longer than the depth with consideration to whether the tool holder will collide.

  • When encountering deep processing, communicate with the programmer and consider using the strategy of indexing the tool multiple times. First index about half to two-thirds of the length, and increase the length when processing to the deeper position to improve processing efficiency.

  • When the cnc industrial machine using an extension sleeve for the tool, pay attention to the depth of the tool and the required length of the tool.

  • When installing the tool head, clean the tapered surface using a cleaning cloth, and clean the corresponding position on the machine tool holder to avoid iron chips affecting accuracy or damaging the machine tool.

  • Generally, use the method of aligning the tool tip to align the tool length (in special cases with application of CNC machine tools, use the middle of the tool to align the tool). Carefully check the program list before aligning the tool.

  • When the program is interrupted or when it is necessary to realign the tool, pay attention to whether the depth can be connected to the previous position. Generally, increase the height by 0.1 mm first and then adjust accordingly.

  • For a rotating and detachable tool head, if using water-soluble cutting fluid, conduct maintenance by soaking the tool in lubricating oil for several hours every half month to lubricate the internal components of the tool head to avoid wear and tear.
