SMTCL TK6916 HORIZONTAL BORING MILLS

Technical Description

The SMTCL TK6916 Horizontal Boring Mill is a CNC floor-type machine designed for heavy-duty boring and milling operations, featuring a robust structure and high-precision control. This model is equipped with a boring spindle diameter of 6.30 inches (Ø160mm) and utilizes an ISO 50 spindle taper. Power is supplied by a main motor generating approximately 51-55 kW (68.5 HP), facilitating a broad spindle speed range, typically between 2 to 1250 RPM or 0.5 to 1500 RPM. The machine is controlled by an advanced CNC system, such as the SIEMENS 840DE, ensuring complex machining capabilities. Key travel specifications often include a longitudinal column travel (X-axis) of 4000+n*1000mm, a vertical boring head travel (Y-axis) of 3000-5000mm, and a boring spindle travel (Z-axis) around 900mm. The TK6916 provides high accuracy, with linear motion coordinates positioning accuracy typically around ±0.025/1000mm for X/Y axes and ±0.03/1000mm for Z/W axes. Its construction and technical parameters make it suitable for machining large workpieces with high precision.
