Product Features

The boring machine is mainly used for repair welding post-processing of shaft pin holes, rotary holes and hinge holes in various engineering machinery structures, or used for inserting sleeves after expanding holes. It is also used for repairing and processing the concentric holes of excavators, loaders, cranes and other machinery. The boring machine can process parallel holes in multiple rows, and conducts one-time positioning processing on the multiple holes to ensure the coaxiality of the multiple holes.

The 110V motor is adopted by the spindle and supporting tools of the boring machine and has the characteristics of low rotating speed and high torque. The whole machine can achieve stable cutting processing and has superior performance. Axial movement and cutting performance are free of vibration. The important guarantee is provided for high precision, high efficiency, high stability and high flexibility boring machining. The stability is better, and the fault rate is lower.

The feed and spindle conduct stepless speed regulation. The speed can be adjusted through the independent remote controller and the speed knob on the main machine, and operation and control are easy and convenient.

The boring bar is of an alloy steel structure. After processing and heat treatment, it has the characteristics of high precision, high hardness, fatigue resistance, wear resistance, etc.

The electric control box is designed for the boring machine, the structure is compact, internal circuits are arranged orderly, and the circuit safety is effectively ensured. The motor controller is equipped with a dynamic delay braking device to avoid vibration during parking.

The tool rests can be installed and fixed at any position within the effective travel range. Different tool rests can be selected to adapt to different workpieces, so that the adaptability is higher. The tool rests are firm and durable and convenient to replace.

Operation Method

After the product is received, the boring machine is installed and used according to the following steps.

1. Installation of Supports
A. Positioning of Boring Rod
Install the supporting bases at the position, where welding is allowed, of the processed part. Fix the boring bar in the to-be-processed hole with supporting bolts, and position the boring bar with positioning sleeves at the two ends to ensure the coaxiality of the two holes.
B. Insert the boring bar into the supporting bases and assemble the two supporting bases at the appropriate position. During welding, pay attention to ensuring that each welding bolt is evenly attached to the workpiece and firmly welded to the workpiece, and also pay attention to ensuring that the boring bar can rotate flexibly and slide axially. If the boring bar is not smooth, adjust the nuts on the welding bolts until it is smooth.

2. After positioning the boring bar in the center through sleeving installation of the supporting bolts, assemble the host connection support (front support) and four M18*160 bolts together, then push the assembled host connection support to the end face of the machined hole along the boring bar, and adjust the gaps between the bolts and the end face to be consistent. Then firmly weld the bolts and the end face. In the same way, assemble the end face support (rear support), push it to the end face of the machined hole along the boring bar, adjust the gaps and weld them firmly.

3. After firmly welding the front and rear supports, remove the positioning sleeves, push and pull the boring bar to ensure smoothness, and at the same time, install a tool (which can be a boring tool) that can be used for straightening in the tool installation hole of the boring bar to conduct straightening operation. If there is a deviation, the operator can loosen the four M12 hexagon socket bolts for fixing the bearing pedestals (no need to completely loosen them, and apply a certain force). There are four M12 jackscrews around the bearing pedestals, and the boring bar can be fine-tuned to the ideal position through the jackscrews. The front and rear supports can be adjusted for several times to achieve the better effect. After adjustment is finished, be sure to remember to tighten the fastening screws of the bearing pedestals of the front and rear supports.

4. At this moment, push the host to the host connection bearing pedestal along the boring bar and connect the host and the host connection bearing pedestal. Align the bolt on the host with the fixing hole on the boring bar, insert the bolt into the fixing hole, lock them, and then tighten the host locking device. It is suggested that the single-side cutting amount should not exceed 2-3mm.

5. Choose the 110V power supply. Connect the plug of the electrical control box to the 110V power supply. When a generator is used, a voltage regulator is required.

6. Selection of Tool Rests
A. The hole diameter is within the range of 65-90mm, and the cutting tool is directly fixed in the tool groove.
B. The hole diameter is within the range of 90-400mm, there are two tool rests that can be selected according to the specific size of the hole positions.

7. Installation of Cutting Tool
Fix the CNC cutting tool to the boring bar or tool rest according to the size of the machined hole.
A. When the tool setting is conducted, please select the neutral gear and manually rotate the boring bar to adjust the tool and to ensure that the tool tip is about 0.2mm away from the workpiece.
B. During the initial cutting, choose the single-side cutting depth to be 0.5-1.0mm for cutting, and carefully observe the cutting condition of the tool to make accurate judgment for normal cutting.

8. During processing, the amount of feed should be selected according to the requirements of the cutting depth (single-side cutting depth: ≤2mm) and the machining accuracy, and the specific surface conditions of the processed workpiece. The amount of feed should be controlled to be 0.02-0.16mm per revolution, and the too fast feed can cause equipment damage.
