Special CNC Vertical Lathe
---VTC Series CNC Vertical Lathe
With a vertical spindle layout and a horizontal rotary table, these CNC vertical lathes perform all the machining processes required for brake drum casting, including turning, drilling, grooving, balancing, and weight removal. Equipped with a four-station electric toolholder, the VTC series CNC vertical lathe support simultaneous switching between roughing and finishing operations, eliminating positioning errors caused by secondary clamping. This significantly improves machining accuracy (repeatability reaches 0.012mm) and surface quality (Ra 1.6 or below).

Equipment Processing Case Studies
Product Details
The base, column, and slide of the CNC vertical lathe are all made of high-grade gray cast iron and are tempered to ensure high strength and long-term precision stability.
The CNC vertical lathes utilize roller-type linear guides, offering exceptional rigidity and heavy-duty load capacity. This significantly improves the positioning accuracy and load capacity of the machine's longitudinal and transverse feed motions.
The CNC vertical lathe's spindle pulley is connected to the CNC servo motor pulley via a belt. It can be equipped with a 22kW motor and features stepless speed change over a wide speed range, meeting the varying spindle speed requirements for roughing and finishing parts.
The CNC vertical lathe's vertical and horizontal feeds are automatically controlled by servo motors. Protective devices in both directions significantly extend the life of the lead screw.

Detailed process control
Follow-action cooling
Three external cooling outlets are located on the left side of the turret, providing high-flow cooling of the tool tip and workpiece flushing, ensuring maximum cleanliness during machining.
CNC vertical lathe manual scraping
In order to obtain higher matching accuracy and ideal contact surface, the fixed surface of the bearing unit and the main shaft are manually scraped and the scraping accuracy reaches above level 0.
CNC vertical lathe laser detection
Before shipment, a laser interferometer is used to eliminate lead screw pitch errors, achieving higher positioning accuracy.
