Mini Bench Drill (Cast Iron Version)

I. Product Overview

The small bench drill of the cast iron version is equipped with a 60W brushed DC motor with a motor speed of 8,000 revolutions. Through the belt pulley transmission with a gear ratio of 1:4, it can achieve multiple rotational speed outputs and can conveniently adjust the forward and reverse rotation. The column supports heightening, which can increase the stroke. According to different needs (cast iron version), three specifications are provided for users to choose from.

III. Introduction to Functional Parts

1. Standard 755 Motor

- It has all-copper coils, power distribution: DC28V, power socket: Φ5.5 x 2.5, and is equipped with a motor forward and reverse switch.

2. Operating Handle

- The arm (made of cast iron).

3. Spindle Kit

- It is precision-machined, and the spindle uses 4 NMB bearings.

4. Reverse and Clockwise Function

- It can be used for drilling or cutting.

IV. Models and Performances

1. Model 04

- Runout accuracy: < 0.03, drill bit clamping range: 0.3 - 3.4, weight: < 1.96KG.

2. Model 05

- Runout accuracy: < 0.05, drill bit clamping range: 0.5 - 6.5, weight: < 2.02KG.

3. Model 06 (ER11)

- Runout accuracy: < 0.01, drill bit clamping range: 0.3 - 6.0, weight: < 1.95KG.

V. Precision Parts and Physical Display
1. Spindle

- It has a size of 30 and drill bit clearance holes. For Model 04: Φ4.0, for Model 05: Φ5.5, for Model 06: Φ7.0.

2. Drive Pulley Combination

- It adopts a rubber multi-ribbed belt (V - ribbed belt), which has the advantages of low noise and high friction. The transmission ratio is 1:4, and the transmission belt guard is 100%.

3. Cast Iron Base, Precision Machining

- The counterweight is 0.62KG, making it more stable. CNC clamping is used for processing surfaces and holes at one time, ensuring precise dimensions, high flatness and perpendicularity.
