Product Overview

The box-way lathe is a CNC horizontal turning machine using broad sliding bed ways rather than rolling linear guides. It is used for roughing steel forgings, cast valve bodies, stainless-steel shafts and other rotational parts with interrupted surfaces or substantial machining allowance.

Key Features

Hardened HT300 Guideway Bed

The bed uses HT300 cast iron with guideway surfaces hardened to HRC 52–58. When machining a forged shaft with an uneven outer skin, the hardened sliding surfaces resist concentrated carriage wear from repeated starts, reversals and changes in cutting force.

Wide Sliding Contact

Guideway width is at least 300 mm, and PTFE-lined sliding interfaces reduce low-speed stick-slip. During fine manual feed correction near a shoulder or shallow groove, smooth carriage motion helps the tool enter the cut without abrupt movement marks.

Cutting Force Capacity

The published X-axis cutting-load rating is at least 8,000 N and the Z-axis rating at least 12,000 N. When a tool crosses interrupted steel-casting features, the bed and saddle have the contact area required to absorb changing loads during heavy roughing.

Custom Box-way Lathe

Machine selection starts from stock hardness, cutting allowance, finished shaft diameter and support conditions. We adapt the workholding and control package to the intended roughing and finishing sequence, then fit and align the sliding assemblies during build.

Quality Control

Each sliding-way assembly is inspected for guideway contact, straightness and carriage travel. Feed movement is checked in both directions to identify binding or lost motion before spindle and tooling acceptance.

The factory verifies spindle alignment, cylindrical turning and surface condition using a standard test workpiece. The completed lathe is subjected to no-load and cutting tests, with inspection responsibilities assigned to individual operations and checked again before packing.
