Horizon Mold Adds a 50-Ton Six-Axis Deep-Hole Driller, Brings Dual-Angle Holes and Compound Frames In-House
Date : 2026-09-24

A six-axis high-precision deep-hole drilling machine with a 50-ton table load capacity has just been installed and commissioned at Horizon Mold’s shop, and it’s already running trial parts. When the machine first landed, quite a few of the senior machinists gathered around it. What makes it stand out is that it can drill deep holes, mill, and handle dual-angle compound frames and hole patterns.

Deep-hole work on large die-casting mold frames has always been a headache. Cooling lines, ejector holes, and compound-angle oil passages rarely run in the same direction. In the past, that meant moving the part from one machine to another, clamping it three or four times, and spending a lot of time on alignment each round. Errors in angle and position could also stack up. This six-axis deep-hole driller has a tilting spindle head and a rotary table, so holes and frames at multiple angles can be machined in one setup. High-pressure through-spindle coolant and synchronized chip evacuation are also on board. Chips clear out smoothly during deep drilling, so they don’t pack up in the hole, and bore finish and straightness stay consistent.

The 50-ton load rating is a practical number for Horizon. The mold frames being built now keep getting bigger—often dozens of tons—and putting them on ordinary equipment feels risky. This machine’s table takes the weight directly, which cuts down on lifting and repositioning. On the trial run, the process team ran a job with a dual-angle compound frame. After machining, it went to the CMM, and both angle and position were within drawing tolerance. The operator said that kind of job used to take two setups. Now it’s done in one, saving nearly half the time.

The machine has been linked to the shop’s MES system, and its maintenance schedule and accuracy records are already in the system. Horizon has been putting serious money into large integrated die-casting mold frames over the past few years. From machining centers to deep-hole drills, the goal is to fill the gap in very large compound machining. With this machine in place, dual-angle deep holes and frame work no longer need to be outsourced. Lead time and accuracy stay in-house.
