KHB Series Horizontal Machining Center
Product Highlights
The KENT CNC KHB Series is built for power and precision, featuring a 10,000 rpm built-in spindle that delivers 310 ft-lb (420 Nm) of torque at 500 rpm, making it ideal for heavy-duty machining of ferrous materials. The B-axis rotary pallet uses a hydraulic locking unit to ensure massive clamping force and machining stability during demanding operations. The index table features a full-circumference hydraulic braking system with a large contact surface, enabling it to withstand high-load, heavy-cutting applications.
Designed with efficiency in mind, the KHB Series comes standard with a high-efficiency automatic pallet changer (APC) to minimize downtime between operations. It’s also compatible with Flexible Manufacturing Systems (FMS), offering scalable automation solutions for advanced production environments. This machine is a strong solution for manufacturers looking for precision, stability, and throughput in demanding metalworking applications.
