Overview

What This Machine Does

The TB8016 is a vertical fine boring machine used mainly for reboring single line and V-engine cylinders of automobiles, motorcycles and tractors, and for other machine element holes. Its defining feature is air-floating location with automatic pressure: the machine is floated into position over the bore quickly and precisely, then set down, rather than being cranked into place. On a V-engine that saves the operator from wrestling the setup for every bank. A tool setting and measuring device is fitted so the boring tool is set to size at the machine, and a separate vertical measuring device covers depth. Spindle speed is chosen to suit the boring work rather than left at one value, and the machine is rigid enough to take a real amount of cutting. Standard and optional accessories are listed separately, so a buyer can specify what actually gets used in their shop rather than paying for a full set.

Key Benefits

Why Buyers Choose This Machine

  • Air-floating location with automatic pressure puts the spindle over the bore quickly and precisely
  • Handles V-engine cylinders as well as single line cylinders, so both banks are bored on one machine
  • Tool setting and measuring device means the boring tool is set to size at the machine
  • Vertical measuring device controls boring depth without a separate gauge
  • Suitable spindle speed for the boring work rather than a single fixed value
  • Good rigidity allows a useful amount of cutting per pass
  • Standard and optional accessory lists let the buyer specify only what the shop will use
Application

Where Cylinder Vertical Air-Floating Fine Boring Machi Earns Its Place

Problems It Solves

  • Repositioning a boring machine by hand over every cylinder of a V-engine is slow and awkward
  • Setting the boring tool away from the machine adds a round trip on every size change
  • Boring depth drifts without a vertical measuring device on the machine
  • A machine without rigidity chatters and spoils the bore on a heavier cut
  • Paying for a full accessory set wastes money when only part of it is used

Who It Is For

  • Engine rebuild shops working on both inline and V-engine blocks
  • Automobile motorcycle and tractor repair workshops
  • Machine shops taking in precision hole boring alongside engine work
  • Distributors equipping engine reconditioning workshops in export markets

Application Scenarios

  • Reboring V-engine cylinders where each bank must be reached in turn
  • Single line automobile engine cylinder reboring
  • Motorcycle and tractor cylinder work in a mixed repair shop
  • Boring other machine element holes to the same accuracy as engine work
  • Batch cylinder work where fast repositioning between bores drives the cycle time

Comparison

How It Compares With the Alternatives

XAIMC T8014A and T8016A cylinder boring machinesThose are clamped boring machines set on the block; the TB8016 is a floor machine with air-floating location that moves to each bore quickly
XAIMC FT7 cylinder boring machineThe FT7 uses a floating table with 4-point automatic centring; the TB8016 uses air-floating location with automatic pressure and adds a vertical measuring device
Boring without a tool setting deviceWithout on-machine tool setting every diameter change means measuring away from the machine, which adds time to every size
Use Guide

Running the Machine

Step 1

Mount the cylinder block on the machine

Step 2

Float the spindle into position over the first bore and let the automatic pressure set it

Step 3

Set the boring tool to size on the tool setting and measuring device

Step 4

Set the boring depth using the vertical measuring device

Step 5

Select a spindle speed suited to the bore diameter and material

Step 6

Bore the cylinder and measure before moving on

Step 7

Float to the next bore, including the opposite bank on a V-engine

FAQ

Questions About Cylinder Vertical Air-Floating Fine Boring M

Can it bore V-engine cylinders?

Yes. It is used for reboring single line cylinders and V-engine cylinders of automobiles motorcycles and tractors, as well as other machine element holes.

What bore diameters and depths does it cover?

Send us the bore diameter range and depth of the cylinders you rebore and we will confirm the machine capacity before you order.

How is the tool set to size?

A tool setting and measuring device is fitted on the machine, so the boring tool is set at the machine rather than at a separate bench.

How is boring depth controlled?

A vertical measuring device is fitted for depth.

Which accessories are standard and which are optional?

The machine comes with a standard accessory set and further items are available as options. Tell us the work you plan to do and we will list exactly what is included in your quotation.

What voltage will it be supplied for?

We set supply voltage and frequency to your market. Confirm your shop supply when you place the order.

What are your payment and trade terms?

FOB CFR and CIF. Payment is 30 percent by T/T on order and 70 percent before shipment, or an irrevocable L/C at sight.
