SMTCL TK6913B HORIZONTAL BORING MILL

The SMTCL TK6913B is a Horizontal Boring Mill, specifically a Floor Type Boring and Milling Machine, often controlled by a CNC system such as the SIEMENS 840DE. Key technical specifications include a spindle diameter of 5.12 inches (or 130mm) with an ISO 50 taper. The machine is designed for heavy-duty metal working, featuring a maximum spindle speed of 1,500 RPM. Power is supplied by a main motor, typically rated between 30 kW and 37 kW (approximately 40 to 49 HP), although a higher specification of 68.8 HP is also noted. The working ranges vary by configuration but generally include a longitudinal travel of the column (X-axis) starting around 4000mm, a vertical travel of the spindle box (Y-axis) between 2000mm and 4000mm, a ram travel (W-axis) of approximately 800mm, and a boring spindle travel (Z-axis) around 700-800mm. The machine is engineered for high precision, with positioning accuracy typically around 0.02mm/1000mm on the X/Y axes.
