What Horizontal Boring Machines Are

By Aisha Jacaruso


When asked, few will tell you what a horizontal boring machine is. They are not even aware of how it can be used in their stores. Doweling is the oldest method that everyone knows about. The purpose of horizontal boring machines is the same but they work uniquely.

With the necessity to produce vast amounts of furniture owing to the growing population resulting to high demand, there was need to come up with an easier way to go about it. This is the root of creation of machine- based horizontally designed drilling process.

At most instances, the mills have been designed in a way that they play the role of an adapter which connects the tool used for cutting to the spindle. This spindle in turn initiates power development and sets motion which stops when tools for cutting are positioned. A bar support operates in various capacities depending on the length of the bars needed to complete the process, Accessibility of bores and levels of finish stringency.

The main types of bars used in drilling are stubs bars and line bars. The stub ones are mounted on spindle end and are used if the holes to be drilled are near the headstock. For regular ones, the provided slots are placed lengthwise to enable the operator insert a flat cutter. Some setscrew require precise placement while other may be adjusted to suit the design. The tools used can be single or double edged. In the event of multiple cutting, extra cutter can be added.

To increase your productivity, use a boring fixture. It gives support to ensure that the piece is aligned to the bars before boring starts. Milling cutter of any type can be used here. End mills make slots, holes and even grooves. Facing cutters are to be used for surface finishing. If you have to achieve circular grooves, you need to be careful. The working parts and constructions of horizontal drilling machines ensure good results.

They have several uses. One is to connect rails to stiles when working on cabinet flushes. The stile at the end is linked to edge at the bottom of rail. Also it can be used to join to an apron to corner square legs. Any two sides of a particular leg are connected to apron using drills. Connection of various narrow boards can be done by employing this machines too. The desired product is a large paneled piece.

You need to consider the power capability of the machine before buying it. Anything between three quarters to two HP is okay. The set table to do the work on should be large enough to support the work pieces. It should have a height adjustability allowance of three to four inches. This is for ease to center holes on both thick and thin work pieces edges. It should be able to be tilted to various angles and if in any case has a slot then the better.

A well sized fence is preferred because it is able to add stops that ensure the holes are placed in consistent manner when doing repetitive tasks on multiple pieces. A good quality boring machine offers you less spindle stroke of three inches.
