The special chamfer lead of the face reamer ensures that it does not necessarily follow the pre-drilled hole, but instead guides itself. This means that even the most demanding requirements for the alignment accuracy of consecutive holes can be met with a face reamer. Furthermore, the cutting face can also be used for machining the bottom of the hole.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ module_id=”high-performance-reamers” _builder_version=”4.25.1″ _module_preset=”default” locked=”off” global_colors_info=”{}”][et_pb_row module_class=”gue-row-1col-text-centered” _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.5″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”3_5,2_5″ module_class=”gue-row-vertical-aligned-content gue-row-2col-image-text” _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”3_5″ _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_video src=”https:\/\/www.youtube.com\/watch?v=24WqNYhXkoA” _builder_version=”4.25.1″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_video][\/et_pb_column][et_pb_column type=”2_5″ _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.5″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n A high-performance reamer enables particularly efficient machining at higher cutting speeds and feed rates thanks to its high-quality cutting material, special coating and particularly precise geometry.

A common mistake is to produce pilot holes with too little stock removal allowance. If there is too little stock removal left in the hole before reaming, the reaming tool cannot cut properly. This causes it to wear out quickly and lose its diameter. It is just as important for good machining performance not to leave too much material in the hole.<\/p>\n [\/et_pb_toggle][et_pb_toggle title=”Tip 4: secure clamping” _builder_version=”4.27.5″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n The workpiece must be securely clamped and the machine spindle must not have any play. Make sure you use a high-quality clamping chuck. If the reaming tool slips in the chuck, the tool may break, especially with an automatic feed. Limit the projection length of the tool from the machine spindle to a minimum.<\/p>\n [\/et_pb_toggle][et_pb_toggle title=”Tip 5: optimum cooling lubricant” _builder_version=”4.27.5″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n Only use recommended cooling lubricants to increase the tool lives and ensure that the cooling lubricant reaches the cutting edges.

This compromises the machining result. The deburring of cross holes in particular is often a time-consuming and cost-intensive work step that has to be carried out manually. This is where the deburring reamer EWR 500 finds its application. The gap between the reamer and hole wall is closed by applying cooling pressure and the burr is cut off cleanly at the root.<\/p>\nA well-rounded affair<\/h2>\n
