Recently, one customer from Argentina inquired about vertical-horizontal turret milling machines. The customer manufactures long shafts for loader and excavator spare parts. Their workpieces are long and large-size parts with a maximum length of 1500mm, so we recommended the XL6336CL model.
Principle of XL6336CL for Machining Long Shaft Workpieces
The XL6336CL is specially optimized for 1.6 m long shaft workpieces. From three dimensions including hardware structure, travel parameters and machining processes, it solves the pain points of standard turret mills such as short worktable, insufficient travel, vibration during long-part cutting and incapability of machining through keyways, enabling stable finish machining of long shaft workpieces.
1：Extended hardware for clamping and travel of long workpieces Equipped with an extended 1600×360 mm worktable and extra-long effective X-axis travel, the machine fully accommodates 1.6 m long shafts. The whole shaft can be clamped in one setup without cutting into segments or repeated re-clamping. It ensures consistent overall accuracy and eliminates errors caused by multiple clamping operations.
2：Heavy-duty rigid structure to avoid deformation and vibration in long-shaft cutting Compared with lightweight 4H/5H turret mills, this machine adopts thickened cast iron body and rectangular hardened wide guideways for greatly improved rigidity. Long shafts tend to vibrate and bend due to large span. The stable frame of XL6336CL absorbs vibration generated during long-distance cutting. No cutter chatter or position shift under heavy cutting, guaranteeing straightness and surface finish of long keyways and flat surfaces.
3：Combined vertical & horizontal spindles covering full long-shaft machining procedures The vertical ISO40 turret head can rotate 360° horizontally and swivel ±45° forward and backward, suitable for machining flat surfaces, steps, inclined planes and sectional keyways on long shafts. The independent horizontal ISO50 spindle is dedicated to through grooves and long slots on full-length shafts. It can complete through milling for the entire shaft in one pass, which is a key advantage unavailable on ordinary single-vertical turret mills.
