Horizontal machining centers with 500-1250 mm worktables use a T-shaped monolithic bed that provides the rigidity needed for heavy-duty cutting. The T-shaped bed distributes cutting forces evenly, reducing deformation during heavy cuts. By keeping heat buildup and vibration under control, the structure helps the machining center maintain stable accuracy throughout long operations.
Once clamped, the workpiece can undergo drilling, boring, reaming, tapping, milling and rough-to-finish contour machining without additional setups. These capabilities suit box-type components used in shipbuilding, automotive production, hydraulic and wind-power equipment, machine tool frames, mold bases and railway assemblies. These horizontal machining centers are built around a design approach that values precision, consistent efficiency, reliable performance, environmental responsibility and reasonable long-term upkeep, making them suitable for continuous production environments.

The four-point kinematic positioning structure, combined with hydraulic clamping, provides high positioning accuracy and strong locking force.
The spindle head uses a hydraulic counterbalance system to support vertical (Y-axis) movement. The hydraulic counterbalance system eases the load created by the spindle head’s weight, allowing the Y-axis to move more smoothly and stay accurate throughout long machining operations.
The ATC is built in two configurations. One uses a mechanical-arm magazine to hold and change tools, while the other relies on a swing-arm mechanism to carry out the tool exchange. The mechanical-arm uses two grippers to pick up and replace tools in a random sequence, and it can handle tools that weigh up to 25 kg without affecting the changeover motion. The spindle uses a No.50 taper interface and works with standard holders such as BT50, ISO50, SK50 and JT50. The tool magazine operates with a chain-type drive and is supplied with a 40-tool capacity as standard. Optional configurations include 60, 80, 100 and 120 tools to meet different production requirements.
The servo motor is connected directly to the ball screw through a precision coupling. The precision coupling minimizes deformation or lateral shift in the ball screw, even under heavy load, allowing the axes to keep their positioning accuracy and improving the overall machining result. The reduced mechanical stress also contributes to longer service life.
Double-screw chip conveyors (THM6380, THM6363A, THM6350 and TH6350) and chain-type conveyors (THM63100 and THM63125) are used to clear chips from the cutting area. The steep-angle guideway covers guide chips into the side channels, where the conveyors move them out of the working zone for smoother, more consistent evacuation. Different conveyor styles are selected according to the model and chip-handling requirements of each horizontal machining center.
Ball Screw
Linear Guideways
High-quality linear guideways and ball screws from THK and NSK are used to support the accuracy and long service life expected in precision machining. Both components are preloaded to remove backlash and maintain load capacity in every direction. The low-friction design allows fast axis movement, smooth low-speed travel and accurate positioning, even when the Z-axis is cutting under heavy load. Each linear guideway is equipped with an independent automatic lubrication system to ensure consistent performance over time. The mounting surfaces for the guideways are hand-scraped to achieve higher installation accuracy and stable motion during machining.

Horizontal machining centers handle complex shapes and parts that require reliable accuracy in repeated production. They are often used for box-type components and multi-surface structures, including engine blocks, aerospace engine elements, aircraft frame sections and turbine blades.
The horizontal layout with a pallet changer lets several faces of a part be machined in a single clamping. With less repositioning, it’s easier to keep the accuracy steady. The pallet system and the automatic tool changer help keep the process moving, so production stays stable even in larger batches.
Applications include automotive components, aerospace structures, marine power parts, construction-equipment housings and precision mold work. The combination of rigidity, accuracy and chip-control capability makes the configuration suitable for cast irons, steels and high-strength alloys.
