The main components and advantages of a bench drill

The main components of a bench drill include a base; Bed and column; Saw beam and transmission mechanism; Guiding device; Workpiece clamping; Tensioning device; Feeding rack; Hydraulic transmission system; Electrical control system; Lubrication and cooling system.

The base of the drill is a box shaped structure welded with steel plates, with the bed and column fixed to it. There is a large space in the inner cavity of the base. The front left side is an electrical button control box, the right side is an electrical distribution board box, and the middle is a hydraulic oil tank welded with steel plates. The cavity is equipped with a hydraulic pump station, hydraulic pipelines, and the right side is a cooling and cutting fluid tank and water pump; The table drill bed is made of cast iron and fixed on the base. The column is composed of a large and small cylinder. The large circular column serves as the guide rail for the saw frame to support the upward and downward movement of the saw beam and ensure accurate guidance. The small cylinder serves as an auxiliary role to ensure the normal cutting of the saw blade.

The center of the bench drill is a clamping vise and a manual feeding mechanism. The front of the vise is connected to a workbench that accepts finished products. The clamping device on the left side is a clamping screw that passes through the inner hole of the hydraulic clamping cylinder rod, and the handwheel or button is turned to move the left jaw left and right. Applicable occasions for bench drills: mainly used for cutting materials in machinery, forging, processing, etc. The hydraulic control of the bench drill sawing speed is infinitely adjustable. Oil cylinder control, stable feeding. Bundling devices can be added according to customer needs. There are semi-automatic and CNC fully automatic options available as needed. Can be used for angle cutting saw machines.

The development of bench drills has gone through a long history and has now become the most commonly used small diameter deep hole machining tools. Gun drills have indeed played an important role in processing cast iron and easily chip steel. Several manufacturers of deep hole machining tools in the country have also used them as their main products for many years. In the past, when it came to machining small diameter deep holes, one immediately thought of a bench drill. However, as the bench drill transitioned from high-speed steel to hard alloy, the linear speed requirements for chips further increased; At the same time, various advanced materials are widely used in production, such as titanium alloy and stainless steel. Under these conditions, using gun drilling to process often results in low processing quality, blade breakage, and tool body twisting.
