The GB42100 Gantry Horizontal Band Saw Machine is a heavy-duty metal cutting machine designed for sawing large-diameter and large-section metal workpieces. With a double-column gantry structure, hydraulic clamping, hydraulic stepless feeding and platform-type material feeding, the machine provides stable support for demanding heavy-duty sawing applications.

The GB42100 is mainly designed for cutting round discs, large cylindrical workpieces, shafts, square forged blocks and the end faces of large forgings. It is suitable for various ferrous metal materials and offers high cutting efficiency, a narrow kerf, reduced material waste and simple operation.

With a maximum cutting capacity of Ø1000 mm for round workpieces and 1000 * 1000 mm for square workpieces, the GB42100 is designed for large-scale metal processing applications where cutting capacity and machine stability are critical.

Key Features

1. Heavy-Duty Double-Column Gantry Structure

The GB42100 adopts a double-column gantry structure designed to provide reliable support and stability during heavy-duty cutting.

The columns are constructed from welded steel plates. Multiple linear guide rails are arranged on the columns to support stable saw-frame movement, while two hydraulic cylinders drive the saw frame simultaneously. This structure helps maintain stable vertical movement during cutting.

2. Extra-Large 1000 mm Cutting Capacity

The GB42100 provides a maximum sawing capacity of:

• Round workpieces: Ø1000 mm
• Square workpieces: 1000 * 1000 mm

This makes it suitable for large shafts, cylindrical workpieces, forged blocks and other large metal components.

3. Hydraulic Stepless Saw Feed

The saw band feed adopts hydraulic stepless adjustment, allowing the feed rate to be continuously adjusted according to different workpiece materials and cutting conditions.

4. Hydraulic Workpiece Clamping

The machine uses front and rear hydraulic vise cylinders to clamp the workpiece. This helps stabilize the material during cutting and supports consistent sawing performance.

5. Hydraulic Automatic Blade Tensioning

The band saw blade uses a hydraulic automatic tensioning system. After the blade is installed on the drive and tension wheels, the tension cylinder applies the required blade tension through hydraulic operation.

6. Stable Saw Frame Construction

The saw frame adopts an arched structure consisting of left and right saw-frame housings and a crossbeam. High-quality steel plates and reinforced welded construction are used, followed by vibration stress relief treatment to redistribute and reduce welding stress.

7. Multi-Guide Linear Rail Structure

The left and right columns are equipped with multiple linear guide rails to improve the stability of saw-frame movement. The saw frame is driven by two hydraulic cylinders simultaneously, helping reduce instability caused by uneven lifting forces.

8. Effective Cooling and Chip Cleaning

The GB42100 uses a centralized cooling pump to circulate coolant to the cutting area. Cooling points are positioned around the left and right guide arms and above the saw blade.

A motor-driven passive chip-cleaning brush is also provided to remove metal chips from the saw band, helping reduce heat accumulation and extend blade service life.

9. Platform Sliding-Carriage Feeding

The machine uses a platform sliding-carriage feeding system. Workpieces are placed on the carriage and moved forward and backward through a hydraulic cylinder.

Feeding and return operations are controlled by buttons, making the system suitable for handling different workpiece sizes.

The specified feeding stroke is 1000 mm, with a material carriage size of 1000 * 1000 mm.

10. Direct-Connected Main Transmission

The main transmission consists of a reducer and drive wheel. The reducer is directly connected to the drive wheel, providing good rigidity, low operating noise and stable power transmission. The machine uses a K-series helical bevel gear reducer for the main drive.
