When using ordinary milling cutters on a horizontal milling machine, the movement trajectory of the cutter edge is a cycloidal curve. Therefore, during upward milling, the chip thickness increases from thin to thick, and the cutter experiences a light initial force followed by a heavy final force, preventing the cutter edge from breaking due to impact. During downward milling, the chip thickness decreases, and the cutter experiences a heavy initial force followed by a heavy final force, making it more susceptible to impact and cutter edge breakage.
When milling on a horizontal milling machine, roughing uses upward milling, and finishing uses downward milling. When using downward milling, the milling machine screw needs a backlash elimination device; otherwise, vibration is likely to occur, resulting in poor cutting surfaces.
Advantages of Horizontal Milling Machines
① High machine rigidity, capable of bearing heavy cutting loads.
② High-power spindle motors with a wide speed range, fully utilizing tool efficiency for high-speed cutting.
③ Wear-prone castings are made of vanadium-titanium wear-resistant cast iron, and critical parts are made of high-quality alloy steel, ensuring stability and durability.
④ The machine tool has a complete lubrication system.
⑤ Horizontal milling machines can be configured with digital display devices according to user needs. This product is easy to operate and reliable in performance. It can be used to process various planes, inclined surfaces, grooves, etc. with various cylindrical milling cutters, disc milling cutters, angle milling cutters, form milling cutters, and end milling cutters.
